-  on Amazon S3. Instead, Garage uses the legacy path-style bucket addressing.
-  Remember to configure your client to acknowledge this fact.
+- **Be careful to DNS-style/path-style access:** Garage supports both DNS-style buckets, which are now by default

+garage bucket website --allow peertube-videos
+```
+
+Finally, we must allow Cross-Origin Resource Sharing (CORS). 
+CORS are required by your browser to allow requests triggered from the peertube website (eg. peertube.tld) to your bucket's domain (eg. peertube-videos.web.garage.tld)
+
+```bash
+export CORS='{"CORSRules":[{"AllowedHeaders":["*"],"AllowedMethods":["GET"],"AllowedOrigins":["*"]}]}'
+aws --endpoint http://s3.garage.localhost s3api put-bucket-cors --bucket peertube-playlists --cors-configuration $CORS
+aws --endpoint http://s3.garage.localhost s3api put-bucket-cors --bucket peertube-videos --cors-configuration $CORS
 ```
 
 These buckets are now accessible on the web port (by default 3902) with the following URL: `http://<bucket><root_domain>:<web_port>` where the root domain is defined in your configuration file (by default `.web.garage`). So we have currently the following URLs: 
-  * http://peertube-playlist.web.garage:3902
-  * http://peertube-video.web.garage:3902
+  * http://peertube-playlists.web.garage:3902
+  * http://peertube-videos.web.garage:3902
 
 Make sure you (will) have a corresponding DNS entry for them.
 
-### Configure a Reverse Proxy to serve CORS
-
-Now we will configure a reverse proxy in front of Garage.
-This is required as we have no other way to serve CORS headers yet.
-Check the [Configuring a reverse proxy](/cookbook/reverse_proxy.html) section to know how.
-
-Now make sure that your 2 dns entries are pointing to your reverse proxy.

+Backups are essential for disaster recovery but they are not trivial to manage.
+Using Garage as your backup target will enable you to scale your storage as needed while ensuring high availability.
+
+## Borg Backup
+
+Borg Backup is very popular among the backup tools but it is not yet compatible with the S3 API.
+We recommend using any other tool listed in this guide because they are all compatible with the S3 API.
+If you still want to use Borg, you can use it with `rclone mount`.
+
+
+
+## Restic
+
+Create your key and bucket:
+
+```bash
+garage key new my-key
+garage bucket create backup
+garage bucket allow backup --read --write --key my-key
+```
+
+Then register your Key ID and Secret key in your environment:
+
+```bash
+export AWS_ACCESS_KEY_ID=GKxxx
+export AWS_SECRET_ACCESS_KEY=xxxx
+```
+
+Configure restic from environment too:
+
+```bash
+export RESTIC_REPOSITORY="s3:http://localhost:3900/backups"
+
+echo "Generated password (save it safely): $(openssl rand -base64 32)"
+export RESTIC_PASSWORD=xxx # copy paste your generated password here
+```
+
+Do not forget to save your password safely (in your password manager or print it). It will be needed to decrypt your backups.
+
+Now you can use restic:
+
+```bash
+# Initialize the bucket, must be run once
+restic init
+
+# Backup your PostgreSQL database
+# (We suppose your PostgreSQL daemon is stopped for all commands)
+restic backup /var/lib/postgresql
+
+# Show backup history
+restic snapshots
+
+# Backup again your PostgreSQL database, it will be faster as only changes will be uploaded
+restic backup /var/lib/postgresql
+
+# Show backup history (again)
+restic snapshots
+
+# Restore a backup
+# (79766175 is the ID of the snapshot you want to restore)
+mv /var/lib/postgresql /var/lib/postgresql.broken
+restic restore 79766175 --target /var/lib/postgresql
+```
+
+Restic has way more features than the ones presented here.
+You can discover all of them by accessing its documentation from the link below.
+
+
+*External links:* [Restic Documentation > Amazon S3](https://restic.readthedocs.io/en/stable/030_preparing_a_new_repo.html#amazon-s3)

+
+## Duplicati
+
+*External links:* [Duplicati Documentation > Storage Providers](https://duplicati.readthedocs.io/en/latest/05-storage-providers/#s3-compatible)
+
+The following fields need to be specified:

+Use SSL: [ ] # Only if you have SSL
+Server: Custom server url (s3.garage.localhost:3900)
+Bucket name: bucket-name
+Bucket create region: Custom region value (garage) # Or as you've specified in garage.toml
+AWS Access ID: Key ID from "garage key info key-name"
+AWS Access Key: Secret key from "garage key info key-name"
+Client Library to use: Minio SDK
+```
+
+Click `Test connection` and then no when asked `The bucket name should start with your username, prepend automatically?`. Then it should say `Connection worked!`.

+
+## kopia
+
+*External links:* [Kopia Documentation > Repositories](https://kopia.io/docs/repositories/#amazon-s3)
+
+To create the Kopia repository, you need to specify the region, the HTTP(S) endpoint, the bucket name and the access keys.
+For instance, if you have an instance of garage running on `https://garage.example.com`:
+
+```
+kopia repository create s3 --region=garage --bucket=mybackups --access-key=KEY_ID --secret-access-key=SECRET_KEY --endpoint=garage.example.com
+```
+
+Or if you have an instance running on localhost, without TLS:
+
+```
+kopia repository create s3 --region=garage --bucket=mybackups --access-key=KEY_ID --secret-access-key=SECRET_KEY --endpoint=localhost:3900 --disable-tls
+```
+
+After the repository has been created, check that everything works as expected:
+
+```
+kopia repository validate-provider
+```
+
+You can then run all the standard kopia commands: `kopia snapshot create`, `kopia mount`...
+Everything should work out-of-the-box.

+## Minio client
+
+Use the following command to set an "alias", i.e. define a new S3 server to be
+used by the Minio client:
+
+```bash
+mc alias set \
+  garage \
+  <endpoint> \
+  <access key> \
+  <secret key> \
+  --api S3v4
+```
+
+Remember that `mc` is sometimes called `mcli` (such as on Arch Linux), to avoid conflicts
+with Midnight Commander.
+
+Some commands:
+
+```bash
+# list buckets
+mc ls garage/
+
+# list objets in a bucket
+mc ls garage/my_files
+
+# copy from your filesystem to garage
+mc cp /proc/cpuinfo garage/my_files/cpuinfo.txt
+
+# copy from garage to your filesystem
+mc cp garage/my_files/cpuinfo.txt /tmp/cpuinfo.txt
+
+# mirror a folder from your filesystem to garage
+mc mirror --overwrite ./book garage/garagehq.deuxfleurs.fr
+```
+
+
+## AWS CLI
+
+Create a file named `~/.aws/credentials` and put:
+
+```toml
+[default]
+aws_access_key_id=xxxx
+aws_secret_access_key=xxxx
+```
+
+Then a file named `~/.aws/config` and put:
+
+```toml
+[default]
+region=garage
+```
+
+Now, supposing Garage is listening on `http://127.0.0.1:3900`, you can list your buckets with:
+
+```bash
+aws --endpoint-url http://127.0.0.1:3900 s3 ls
+```
+
+Passing the `--endpoint-url` parameter to each command is annoying but AWS developers do not provide a corresponding configuration entry.
+As a workaround, you can redefine the aws command by editing the file `~/.bashrc`:
+
+```
+function aws { command aws --endpoint-url http://127.0.0.1:3900 $@ ; }
+```
+
+*Do not forget to run `source ~/.bashrc` or to start a new terminal before running the next commands.*
+
+Now you can simply run:
+
+```bash
+# list buckets
+aws s3 ls
+
+# list objects of a bucket
+aws s3 ls s3://my_files
+
+# copy from your filesystem to garage
+aws s3 cp /proc/cpuinfo s3://my_files/cpuinfo.txt
+
+# copy from garage to your filesystem
+aws s3 cp s3/my_files/cpuinfo.txt /tmp/cpuinfo.txt
+```
+
+## `rclone`
+
+`rclone` can be configured using the interactive assistant invoked using `rclone config`.
+
+You can also configure `rclone` by writing directly its configuration file.
+Here is a template `rclone.ini` configuration file (mine is located at `~/.config/rclone/rclone.conf`):
+
+```ini
+[garage]
+type = s3
+provider = Other
+env_auth = false
+access_key_id = <access key>
+secret_access_key = <secret key>
+region = <region>
+endpoint = <endpoint>
+force_path_style = true
+acl = private
+bucket_acl = private
+```
+
+Now you can run:
+
+```bash
+# list buckets
+rclone lsd garage:
+
+# list objects of a bucket aggregated in directories
+rclone lsd garage:my-bucket
+
+# copy from your filesystem to garage
+echo hello world > /tmp/hello.txt
+rclone copy /tmp/hello.txt garage:my-bucket/
+
+# copy from garage to your filesystem
+rclone copy garage:quentin.divers/hello.txt .
+
+# see all available subcommands
+rclone help
+```
+
+**Advice with rclone:** use the `--fast-list` option when accessing buckets with large amounts of objects.
+This will tremendously accelerate operations such as `rclone sync` or `rclone ncdu` by reducing the number
+of ListObjects calls that are made.
+
+
+## `s3cmd`
+
+Here is a template for the `s3cmd.cfg` file to talk with Garage:
+
+```ini
+[default]
+access_key = <access key>
+secret_key = <secret key>
+host_base = <endpoint without http(s)://>
+host_bucket = <same as host_base>
+use_https = <False or True>
+```
+
+And use it as follow:
+
+```bash
+# List buckets
+s3cmd ls
+
+# s3cmd objects inside a bucket
+s3cmd ls s3://my-bucket
+
+# copy from your filesystem to garage
+echo hello world > /tmp/hello.txt
+s3cmd put /tmp/hello.txt s3://my-bucket/
+
+# copy from garage to your filesystem
+s3cmd get s3://my-bucket/hello.txt hello.txt
+```
+
+## Cyberduck & duck {#cyberduck}
+
+Both Cyberduck (the GUI) and duck (the CLI) have a concept of "Connection Profiles" that contain some presets for a specific provider.
+We wrote the following connection profile for Garage:
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>

+        <array>
+            <string>garage</string>
+        </array>
+    </dict>
+</plist>
+```
+
+*Note: If your garage instance is configured with vhost access style, you can remove `s3service.disable-dns-buckets=true`.*
+
+### Instructions for the GUI
+
+Copy the connection profile, and save it anywhere as `garage.cyberduckprofile`.
+Then find this file with your file explorer and double click on it: Cyberduck will open a connection wizard for this profile.
+Simply follow the wizard and you should be done!
+
+### Instuctions for the CLI
+
+To configure duck (Cyberduck's CLI tool), start by creating its folder hierarchy:
+
+```
+mkdir -p ~/.duck/profiles/
+```
+
+Then, save the connection profile for Garage in `~/.duck/profiles/garage.cyberduckprofile`.
+To set your credentials in `~/.duck/credentials`, use the following commands to generate the appropriate string:
+
+```bash
+export AWS_ACCESS_KEY_ID="GK..."
+export AWS_SECRET_ACCESS_KEY="..."
+export HOST="s3.garage.localhost"
+export PORT="4443"
+export PROTOCOL="https"
+
+cat > ~/.duck/credentials <<EOF
+$PROTOCOL\://$AWS_ACCESS_KEY_ID@$HOST\:$PORT=$AWS_SECRET_ACCESS_KEY
+EOF
+```
+
+And finally, I recommend appending a small wrapper to your `~/.bashrc` to avoid setting the username on each command (do not forget to replace `GK...` by your access key):
+
+```bash
+function duck { command duck --username GK... $@ ; }
+```
+
+Finally, you can then use `duck` as follow:
+
+```bash
+# List buckets
+duck --list garage:/
+
+# List objects in a bucket
+duck --list garage:/my-files/
+
+# Download an object
+duck --download garage:/my-files/an-object.txt /tmp/object.txt
+
+# Upload an object
+duck --upload /tmp/object.txt garage:/my-files/another-object.txt
+
+# Delete an object
+duck --delete garage:/my-files/an-object.txt
+```
+
+## WinSCP (libs3) {#winscp}
+
+*You can find instructions on how to use the GUI in french [in our wiki](https://wiki.deuxfleurs.fr/fr/Guide/Garage/WinSCP).*
+
+How to use `winscp.com`, the CLI interface of WinSCP:
+
+```
+open s3://GKxxxxx:yyyyyyy@127.0.0.1:4443 -certificate=* -rawsettings S3DefaultRegion=garage S3UrlStyle=1
+ls
+ls my-files/
+get my-files/an-object.txt Z:\tmp\object.txt
+put Z:\tmp\object.txt my-files/another-object.txt
+rm my-files/an-object
+exit
+```
+
+Notes:
+  - It seems WinSCP supports only TLS connections for S3
+  - `-certificate=*` allows self-signed certificates, remove it if you have valid certificates
+
+
+## sftpgo {#sftpgo}
+
+sftpgo needs a database to work, by default it uses sqlite and does not require additional configuration.
+You can then directly init it:
+
+```
+sftpgo initprovider
+```
+
+Then you can directly launch the daemon that will listen by default on `:8080 (http)` and `:2022 (ssh)`:
+
+```
+sftpgo serve
+```
+
+Go to the admin web interface (http://[::1]:8080/web/admin/), create the required admin account, then create a user account.
+Choose a username (eg: `ada`) and a password.
+
+In the filesystem section, choose:
+  - Storage: AWS S3 (Compatible)
+  - Bucket: *your bucket name*
+  - Region: `garage` (or the one you defined in `config.toml`)
+  - Access key: *your access key*
+  - Access secret: *your secret key*
+  - Endpoint: *your endpoint*, eg. `https://garage.example.tld`, note that the protocol (`https` here) must be specified. Non standard ports and `http` have not been tested yet.
+  - Keep the default values for other fields
+  - Tick "Use path-style addressing". It should work without ticking it if you have correctly configured your instance to use URL vhost-style.
+
+Now you can access your bucket through SFTP:
+
+```
+sftp -P2022 ada@[::1]
+ls
+```
+
+And through the web interface at http://[::1]:8080/web/client

+
+## Configuring a bucket for website access
+
+There are two methods to expose buckets as website:
+
+1. using the PutBucketWebsite S3 API call, which is allowed for access keys that have the owner permission bit set
+
+2. from the Garage CLI, by an adminstrator of the cluster
+
+The `PutBucketWebsite` API endpoint [is documented](https://docs.aws.amazon.com/AmazonS3/latest/API/API_PutBucketWebsite.html) in the official AWS docs.
+This endpoint can also be called [using `aws s3api`](https://docs.aws.amazon.com/cli/latest/reference/s3api/put-bucket-website.html) on the command line.
+The website configuration supported by Garage is only a subset of the possibilities on Amazon S3: redirections are not supported, only the index document and error document can be specified.
+
+If you want to expose your bucket as a website from the CLI, use this simple command:
+
+```bash
+garage bucket website --allow my-website
+```
+
+Now it will be **publicly** exposed on the web endpoint (by default listening on port 3902).
+
+## How exposed websites work
+
+Our website serving logic is as follow:
+
+  - Supports only static websites (no support for PHP or other languages)
+  - Does not support directory listing
+  - The index file is defined per-bucket and can be specified in the `PutBucketWebsite` call
+     or on the CLI using the `--index-document` parameter (default: `index.html`)
+  - A custom error document for 404 errors can be specified in the `PutBucketWebsite` call
+    or on the CLI using the `--error-document` parameter
+
+Now we need to infer the URL of your website through your bucket name.
+Let assume:
+  - we set `root_domain = ".web.example.com"` in `garage.toml` ([ref](@/documentation/reference-manual/configuration.md#root_domain))
+  - our bucket name is `garagehq.deuxfleurs.fr`.
+
+Our bucket will be served if the Host field matches one of these 2 values (the port is ignored):
+
+  - `garagehq.deuxfleurs.fr.web.example.com`: you can dedicate a subdomain to your users (here `web.example.com`).
+
+  - `garagehq.deuxfleurs.fr`: your users can bring their own domain name, they just need to point them to your Garage cluster.
+
+You can try this logic locally, without configuring any DNS, thanks to `curl`:
+
+```bash
+# prepare your test
+echo hello world > /tmp/index.html
+mc cp /tmp/index.html garage/garagehq.deuxfleurs.fr
+
+curl -H 'Host: garagehq.deuxfleurs.fr' http://localhost:3902
+# should print "hello world"
+
+curl -H 'Host: garagehq.deuxfleurs.fr.web.example.com' http://localhost:3902
+# should also print "hello world"
+```
+
+Now that you understand how website logic works on Garage, you can:
+
+ - make the website endpoint listens on port 80 (instead of 3902)
+ - use iptables to redirect the port 80 to the port 3902:  
+   `iptables -t nat -A PREROUTING -p tcp -dport 80 -j REDIRECT -to-port 3902`
+ - or configure a [reverse proxy](@/documentation/cookbook/reverse-proxy.md) in front of Garage to add TLS (HTTPS), CORS support, etc.
+
+You can also take a look at [Website Integration](@/documentation/connect/websites.md) to see how you can add Garage to your workflow.

+
+The main reason to add a reverse proxy in front of Garage is to provide TLS to your users and serve multiple web services on port 443.
+
+In production you will likely need your certificates signed by a certificate authority.
+The most automated way is to use a provider supporting the [ACME protocol](https://datatracker.ietf.org/doc/html/rfc8555) 
+such as [Let's Encrypt](https://letsencrypt.org/), [ZeroSSL](https://zerossl.com/) or [Buypass Go SSL](https://www.buypass.com/ssl/products/acme).
+
+If you are only testing Garage, you can generate a self-signed certificate to follow the documentation:
+
+```bash
+openssl req \
+    -new \
+    -x509 \
+    -keyout /tmp/garage.key \
+    -out /tmp/garage.crt \
+    -nodes  \
+    -subj "/C=XX/ST=XX/L=XX/O=XX/OU=XX/CN=localhost/emailAddress=X@X.XX" \
+    -addext "subjectAltName = DNS:localhost, IP:127.0.0.1"
+
+cat /tmp/garage.key /tmp/garage.crt > /tmp/garage.pem
+```
+
+Be careful as you will need to allow self signed certificates in your client.
+For example, with minio, you must add the `--insecure` flag.
+An example:
+
+```bash
+mc ls --insecure garage/
+```
+
+## socat (only for testing purposes)
+
+If you want to test Garage with a TLS frontend, socat can do it for you in a single command:
+
+```bash
+socat \

+reuseaddr,\
+fork,\
+verify=0,\
+cert=/tmp/garage.pem" \
+tcp4-connect:localhost:3900
+```
+
+## Nginx
+
+Nginx is a well-known reverse proxy suitable for production.
+We do the configuration in 3 steps: first we define the upstream blocks ("the backends")
+then we define the server blocks ("the frontends") for the S3 endpoint and finally for the web endpoint.
+
+The following configuration blocks can be all put in the same `/etc/nginx/sites-available/garage.conf`.
+To make your configuration active, run `ln -s /etc/nginx/sites-available/garage.conf /etc/nginx/sites-enabled/`.
+If you directly put the instructions in the root `nginx.conf`, keep in mind that these configurations must be enclosed inside a `http { }` block.
+
+And do not forget to reload nginx with `systemctl reload nginx` or `nginx -s reload`.
+
+### Exposing the S3 endpoints
+
+First, we need to tell to nginx how to access our Garage cluster.
+Because we have multiple nodes, we want to leverage all of them by spreading the load.
+In nginx, we can do that with the `upstream` directive.
+
+Then in a `server` directive, we define the vhosts, the TLS certificates and the proxy rule.
+
+A possible configuration:
+
+```nginx
+upstream s3_backend {
+  # if you have a garage instance locally
+  server 127.0.0.1:3900;
+  # you can also put your other instances
+  server 192.168.1.3:3900;
+  # domain names also work
+  server garage1.example.com:3900;
+  # you can assign weights if you have some servers 
+  # that are more powerful than others
+  server garage2.example.com:3900 weight=2;
+}
+
+server {
+  listen [::]:443 http2 ssl;
+
+  ssl_certificate     /tmp/garage.crt;
+  ssl_certificate_key /tmp/garage.key;
+
+  # You need multiple server names here:
+  #  - s3.garage.tld is used for path-based s3 requests
+  #  - *.s3.garage.tld is used for vhost-based s3 requests
+  server_name s3.garage.tld *.s3.garage.tld;
+
+  location / {
+    proxy_pass http://s3_backend;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header Host $host;
+  }
+}
+```
+
+### Exposing the web endpoint
+
+To better understand the logic involved, you can refer to the [Exposing buckets as websites](/cookbook/exposing_websites.html) section.
+Otherwise, the configuration is very similar to the S3 endpoint.
+You must only adapt `upstream` with the web port instead of the s3 port and change the `server_name` and `proxy_pass` entry
+
+A possible configuration:
+
+
+```nginx
+upstream web_backend {
+  server 127.0.0.1:3902;
+  server 192.168.1.3:3902;
+  server garage1.example.com:3902;
+  server garage2.example.com:3902 weight=2;
+}
+
+server {
+  listen [::]:443 http2 ssl;
+
+  ssl_certificate     /tmp/garage.crt;
+  ssl_certificate_key /tmp/garage.key;
+
+  # You need multiple server names here:
+  #  - *.web.garage.tld is used for your users wanting a website without reserving a domain name
+  #  - example.com, my-site.tld, etc. are reserved domain name by your users that chose to host their website as a garage's bucket
+  server_name *.web.garage.tld example.com my-site.tld;
+
+  location / {
+    proxy_pass http://web_backend;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header Host $host;
+  }
+}
+```

+## Traefik v2
+
+We will see in this part how to set up a reverse proxy with [Traefik](https://docs.traefik.io/).

+```toml
+[http.services]
+  [http.services.my_garage_service.loadBalancer]
+    [[http.services.my_garage_service.loadBalancer.servers]]
+      url = "http://xxx.xxx.xxx.xxx"
+      port = 3900
+```
+
+It's possible to declare multiple Garage servers as back-ends:
+
+```toml
+[http.services]
+    [[http.services.my_garage_service.loadBalancer.servers]]
+      url = "http://xxx.xxx.xxx.xxx"
+      port = 3900
+    [[http.services.my_garage_service.loadBalancer.servers]]
+      url = "http://yyy.yyy.yyy.yyy"
+      port = 3900
+    [[http.services.my_garage_service.loadBalancer.servers]]
+      url = "http://zzz.zzz.zzz.zzz"
+      port = 3900
+```
+
+Traefik can remove unhealthy servers automatically with [a health check configuration](https://doc.traefik.io/traefik/routing/services/#health-check):
+
+```
+[http.services]
+  [http.services.my_garage_service.loadBalancer]
+    [http.services.my_garage_service.loadBalancer.healthCheck]
+      path = "/"
+      interval = "60s"
+      timeout = "5s"
+```
+
+### Adding a website
+
+To add a new website, add the following declaration to your Traefik configuration file:
+
+```toml
+[http.routers]
+  [http.routers.my_website]
+    rule = "Host(`yoururl.example.org`)"
+    service = "my_garage_service"
+    entryPoints = ["web"]
+```
+
+Enable HTTPS access to your website with the following configuration section ([documentation](https://doc.traefik.io/traefik/https/overview/)):
+
+```toml
+...
+    entryPoints = ["websecure"]
+    [http.routers.my_website.tls]
+      certResolver = "myresolver"
+...
+```
+
+### Adding gzip compression
+
+Add the following configuration section [to compress response](https://doc.traefik.io/traefik/middlewares/http/compress/) using [gzip](https://developer.mozilla.org/en-US/docs/Glossary/GZip_compression) before sending them to the client:
+
+```toml
+[http.routers]
+  [http.routers.my_website]
+    ...
+    middlewares = ["gzip_compress"]
+    ...
+[http.middlewares]
+  [http.middlewares.gzip_compress.compress]
+```
+
+### Add caching response
+
+Traefik's caching middleware is only available on [entreprise version](https://doc.traefik.io/traefik-enterprise/middlewares/http-cache/), however the freely-available [Souin plugin](https://github.com/darkweak/souin#tr%C3%A6fik-container) can also do the job. (section to be completed)
+
+### Complete example
+
+```toml
+[entryPoints]
+  [entryPoints.web]

+
+Garage is a stateful clustered application, where all nodes are communicating together and share data structures.
+It makes upgrade more difficult than stateless applications so you must be more careful when upgrading.
+On a new version release, there is 2 possibilities:
+  - protocols and data structures remained the same ➡️ this is a **straightforward upgrade**
+  - protocols or data structures changed  ➡️  this is an **advanced upgrade**
+
+You can quickly now what type of update you will have to operate by looking at the version identifier.
+Following the [SemVer ](https://semver.org/) terminology, if only the *patch* number changed, it will only need a straightforward upgrade.
+Example: an upgrade from v0.6.0 from v0.6.1 is a straightforward upgrade.
+If the *minor* or *major* number changed however, you will have to do an advanced upgrade. Example: from v0.6.1 to v0.7.0.
+
+Migrations are designed to be run only between contiguous versions (from a *major*.*minor* perspective, *patches* can be skipped).
+Example: migrations from v0.6.1 to v0.7.0 and from v0.6.0 to v0.7.0 are supported but migrations from v0.5.0 to v0.7.0 are not supported.
+
+## Straightforward upgrades
+
+Straightforward upgrades do not imply cluster downtime.
+Before upgrading, you should still read [the changelog](https://git.deuxfleurs.fr/Deuxfleurs/garage/releases) and ideally test your deployment on a staging cluster before.
+
+When you are ready, start by checking the health of your cluster.
+You can force some checks with `garage repair`, we recommend at least running `garage repair --all-nodes --yes` that is very quick to run (less than a minute).
+You will see that the command correctly terminated in the logs of your daemon.
+
+Finally, you can simply upgrades nodes one by one. 
+For each node: stop it, install the new binary, edit the configuration if needed, restart it. 
+
+## Advanced upgrades
+
+Advanced upgrades will imply cluster downtime.
+Before upgrading, you must read [the changelog](https://git.deuxfleurs.fr/Deuxfleurs/garage/releases) and you must test your deployment on a staging cluster before.
+
+From a high level perspective, an advanced upgrade looks like this:
+  1. Make sure the health of your cluster is good (see `garage repair`)
+  2. Disable API access (comment the configuration in your reverse proxy)
+  3. Check that your cluster is idle
+  4. Stop the whole cluster
+  5. Backup the metadata folder of all your nodes, so that you will be able to restore it quickly if the upgrade fails (blocks being immutable, they should not be impacted)
+  6. Install the new binary, update the configuration
+  7. Start the whole cluster
+  8. If needed, run the corresponding migration from `garage migrate`
+  9. Make sure the health of your cluster is good
+  10. Enable API access (uncomment the configuration in your reverse proxy)
+  11. Monitor your cluster while load comes back, check that all your applications are happy with this new version
+
+We write guides for each advanced upgrade, they are stored under the "Working Documents" section of this documentation.

+**WARNING.** At this point, there is no comittement to stability of the APIs described in this document.
+We will bump the version numbers prefixed to each API endpoint at each time the syntax

+
+The Garage administration API was introduced in version 0.7.2, this document

+
+
+## Access control
+
+The admin API uses two different tokens for acces control, that are specified in the config file's `[admin]` section:
+
+- `metrics_token`: the token for accessing the Metrics endpoint (if this token
+  is not set in the config file, the Metrics endpoint can be accessed without
+  access control);
+
+- `admin_token`: the token for accessing all of the other administration
+  endpoints (if this token is not set in the config file, access to these
+  endpoints is disabled entirely).
+
+These tokens are used as simple HTTP bearer tokens. In other words, to
+authenticate access to an admin API endpoint, add the following HTTP header
+to your request:
+
+```
+Authorization: Bearer <token>
+```
+
+## Administration API endpoints
+
+### Metrics-related endpoints
+
+#### Metrics `GET /metrics`

+### Cluster operations

+#### GetClusterStatus `GET /v0/status`
+

+    }
+]
+```
+
+#### GetClusterLayout `GET /v0/layout`
+
+Returns the cluster's current layout in JSON, including:
+
+- Currently configured cluster layout
+- Staged changes to the cluster layout
+
+(the info returned by this endpoint is a subset of the info returned by GetClusterStatus)
+
+Example response body:

+      ]
+    }
+  }
+}
+```
+
+#### UpdateClusterLayout `POST /v0/layout`
+
+Send modifications to the cluster layout. These modifications will
+be included in the staged role changes, visible in subsequent calls
+of `GetClusterLayout`. Once the set of staged changes is satisfactory,
+the user may call `ApplyClusterLayout` to apply the changed changes,
+or `Revert ClusterLayout` to clear all of the staged changes in
+the layout.
+
+Request body format:
+
+```json
+{
+  <node_id>: {
+    "capacity": <new_capacity>,
+    "zone": <new_zone>,
+    "tags": [
+      <new_tag>,
+      ...
+    ]
+  },
+  <node_id_to_remove>: null,
+  ...
+}
+```
+
+Contrary to the CLI that may update only a subset of the fields
+`capacity`, `zone` and `tags`, when calling this API all of these
+values must be specified.
+
+
+#### ApplyClusterLayout `POST /v0/layout/apply`
+
+Applies to the cluster the layout changes currently registered as
+staged layout changes.
+
+Request body format:
+
+```json
+{
+  "version": 13
+}
+```
+
+Similarly to the CLI, the body must include the version of the new layout
+that will be created, which MUST be 1 + the value of the currently
+existing layout in the cluster.
+
+#### RevertClusterLayout `POST /v0/layout/revert`
+
+Clears all of the staged layout changes.
+
+Request body format:
+
+```json
+{
+  "version": 13
+}
+```
+
+Reverting the staged changes is done by incrementing the version number
+and clearing the contents of the staged change list.
+Similarly to the CLI, the body must include the incremented
+version number, which MUST be 1 + the value of the currently
+existing layout in the cluster.
+
+
+### Access key operations
+
+#### ListKeys `GET /v0/key`
+
+Returns all API access keys in the cluster.
+
+Example response:

+    "id": "GKe10061ac9c2921f09e4c5540",
+    "name": "test2"
+  }
+]
+```
+
+#### CreateKey `POST /v0/key`
+
+Creates a new API access key.
+
+Request body format:
+
+```json
+{
+    "name": "NameOfMyKey"
+}
+```
+
+#### ImportKey `POST /v0/key/import`
+
+Imports an existing API key.
+
+Request body format:

+{
+    "accessKeyId": "GK31c2f218a2e44f485b94239e",
+    "secretAccessKey": "b892c0665f0ada8a4755dae98baa3b133590e11dae3bcc1f9d769d67f16c3835",
+    "name": "NameOfMyKey"
+}
+```
+
+#### GetKeyInfo `GET /v0/key?id=<acces key id>`
+#### GetKeyInfo `GET /v0/key?search=<pattern>`
+
+Returns information about the requested API access key.
+
+If `id` is set, the key is looked up using its exact identifier (faster).

+(both are fast)
+
+Example response:
+
+```json
+{

+            "maxSize": null,
+            "maxObjects": null
+        }
+}
+```
+
+#### CreateBucket `POST /v0/bucket`
+
+Creates a new storage bucket.
+
+Request body format:
+
+```json
+{
+    "globalAlias": "NameOfMyBucket"
+}
+```
+
+OR
+
+```json
+{
+    "localAlias": {

+        }
+    }
+}
+```
+
+OR
+
+```json
+{}
+```
+
+Creates a new bucket, either with a global alias, a local one,
+or no alias at all.
+
+Technically, you can also specify both `globalAlias` and `localAlias` and that would create
+two aliases, but I don't see why you would want to do that.
+
+#### DeleteBucket `DELETE /v0/bucket?id=<bucket id>`
+
+Deletes a storage bucket. A bucket cannot be deleted if it is not empty.
+
+Warning: this will delete all aliases associated with the bucket!
+
+#### UpdateBucket `PUT /v0/bucket?id=<bucket id>`
+
+Updates configuration of the given bucket.
+
+Request body format:
+
+```json
+{
+    "websiteAccess": {
+        "enabled": true,
+        "indexDocument": "index.html",
+        "errorDocument": "404.html"

+    "quotas": {
+        "maxSize": 19029801,
+        "maxObjects": null,
+    }
+}
+```
+
+All fields (`websiteAccess` and `quotas`) are optionnal.
+If they are present, the corresponding modifications are applied to the bucket, otherwise nothing is changed.
+
+In `websiteAccess`: if `enabled` is `true`, `indexDocument` must be specified.
+The field `errorDocument` is optional, if no error document is set a generic
+error message is displayed when errors happen. Conversely, if `enabled` is
+`false`, neither `indexDocument` nor `errorDocument` must be specified.
+
+In `quotas`: new values of `maxSize` and `maxObjects` must both be specified, or set to `null`
+to remove the quotas. An absent value will be considered the same as a `null`. It is not possible
+to change only one of the two quotas.
+
+### Operations on permissions for keys on buckets
+
+#### BucketAllowKey `POST /v0/bucket/allow`
+
+Allows a key to do read/write/owner operations on a bucket.
+
+Request body format:
+
+```json
+{
+    "bucketId": "e6a14cd6a27f48684579ec6b381c078ab11697e6bc8513b72b2f5307e25fff9b",

+        "read": true,
+        "write": true,
+        "owner": true
+    },
+}
+```
+
+Flags in `permissions` which have the value `true` will be activated.
+Other flags will remain unchanged.
+
+#### BucketDenyKey `POST /v0/bucket/deny`
+
+Denies a key from doing read/write/owner operations on a bucket.
+
+Request body format:
+
+```json
+{
+    "bucketId": "e6a14cd6a27f48684579ec6b381c078ab11697e6bc8513b72b2f5307e25fff9b",
+    "accessKeyId": "GK31c2f218a2e44f485b94239e",
+    "permissions": {
+        "read": false,
+        "write": false,
+        "owner": true
+    },
+}
+```
+
+Flags in `permissions` which have the value `true` will be deactivated.
+Other flags will remain unchanged.
+
+
+### Operations on bucket aliases
+
+#### GlobalAliasBucket `PUT /v0/bucket/alias/global?id=<bucket id>&alias=<global alias>`
+
+Empty body. Creates a global alias for a bucket.
+
+#### GlobalUnaliasBucket `DELETE /v0/bucket/alias/global?id=<bucket id>&alias=<global alias>`
+
+Removes a global alias for a bucket.
+
+#### LocalAliasBucket `PUT /v0/bucket/alias/local?id=<bucket id>&accessKeyId=<access key ID>&alias=<local alias>`
+
+Empty body. Creates a local alias for a bucket in the namespace of a specific access key.
+
+#### LocalUnaliasBucket `DELETE /v0/bucket/alias/local?id=<bucket id>&accessKeyId<access key ID>&alias=<local alias>`
+
+Removes a local alias for a bucket in the namespace of a specific access key.

+## Available configuration options
+
+### `metadata_dir`
+
+The directory in which Garage will store its metadata. This contains the node identifier,
+the network configuration and the peer list, the list of buckets and keys as well
+as the index of all objects, object version and object blocks.
+
+Store this folder on a fast SSD drive if possible to maximize Garage's performance.
+
+### `data_dir`
+
+The directory in which Garage will store the data blocks of objects.
+This folder can be placed on an HDD. The space available for `data_dir`
+should be counted to determine a node's capacity
+when [adding it to the cluster layout](@/documentation/cookbook/real-world.md).
+
+### `block_size`
+
+Garage splits stored objects in consecutive chunks of size `block_size`
+(except the last one which might be smaller). The default size is 1MB and
+should work in most cases. We recommend increasing it to e.g. 10MB if
+you are using Garage to store large files and have fast network connections
+between all nodes (e.g. 1gbps).
+
+If you are interested in tuning this, feel free to do so (and remember to
+report your findings to us!). When this value is changed for a running Garage
+installation, only files newly uploaded will be affected. Previously uploaded
+files will remain available. This however means that chunks from existing files
+will not be deduplicated with chunks from newly uploaded files, meaning you
+might use more storage space that is optimally possible.
+
+### `block_manager_background_tranquility`
+
+This parameter tunes the activity of the background worker responsible for
+resyncing data blocks between nodes. The higher the tranquility value is set,
+the more the background worker will wait between iterations, meaning the load
+on the system (including network usage between nodes) will be reduced. The
+minimal value for this parameter is `0`, where the background worker will
+allways work at maximal throughput to resynchronize blocks. The default value
+is `2`, where the background worker will try to spend at most 1/3 of its time
+working, and 2/3 sleeping in order to reduce system load.
+
+### `replication_mode`
+
+Garage supports the following replication modes:
+
+- `none` or `1`: data stored on Garage is stored on a single node. There is no
+  redundancy, and data will be unavailable as soon as one node fails or its
+  network is disconnected.  Do not use this for anything else than test
+  deployments.
+
+- `2`: data stored on Garage will be stored on two different nodes, if possible
+  in different zones. Garage tolerates one node failure, or several nodes
+  failing but all in a single zone (in a deployment with at least two zones),
+  before losing data. Data remains available in read-only mode when one node is
+  down, but write operations will fail.
+
+  - `2-dangerous`: a variant of mode `2`, where written objects are written to
+    the second replica asynchronously. This means that Garage will return `200
+    OK` to a PutObject request before the second copy is fully written (or even
+    before it even starts being written).  This means that data can more easily
+    be lost if the node crashes before a second copy can be completed.  This
+    also means that written objects might not be visible immediately in read
+    operations.  In other words, this mode severely breaks the consistency and
+    durability guarantees of standard Garage cluster operation.  Benefits of
+    this mode: you can still write to your cluster when one node is
+    unavailable.
+
+- `3`: data stored on Garage will be stored on three different nodes, if
+  possible each in a different zones.  Garage tolerates two node failure, or
+  several node failures but in no more than two zones (in a deployment with at
+  least three zones), before losing data. As long as only a single node fails,
+  or node failures are only in a single zone, reading and writing data to
+  Garage can continue normally.
+
+  - `3-degraded`: a variant of replication mode `3`, that lowers the read
+    quorum to `1`, to allow you to read data from your cluster when several
+    nodes (or nodes in several zones) are unavailable.  In this mode, Garage
+    does not provide read-after-write consistency anymore.  The write quorum is
+    still 2, ensuring that data successfully written to Garage is stored on at
+    least two nodes.
+
+  - `3-dangerous`: a variant of replication mode `3` that lowers both the read
+    and write quorums to `1`, to allow you to both read and write to your
+    cluster when several nodes (or nodes in several zones) are unavailable.  It
+    is the least consistent mode of operation proposed by Garage, and also one
+    that should probably never be used.
+
+Note that in modes `2` and `3`,
+if at least the same number of zones are available, an arbitrary number of failures in 
+any given zone is tolerated as copies of data will be spread over several zones.
+
+**Make sure `replication_mode` is the same in the configuration files of all nodes.
+Never run a Garage cluster where that is not the case.**
+
+The quorums associated with each replication mode are described below:
+
+| `replication_mode` | Number of replicas | Write quorum | Read quorum | Read-after-write consistency? |
+| ------------------ | ------------------ | ------------ | ----------- | ----------------------------- |
+| `none` or `1`      | 1                  | 1            | 1           | yes                           |
+| `2`                | 2                  | 2            | 1           | yes                           |
+| `2-dangerous`      | 2                  | 1            | 1           | NO                            |
+| `3`                | 3                  | 2            | 2           | yes                           |
+| `3-degraded`       | 3                  | 2            | 1           | NO                            |
+| `3-dangerous`      | 3                  | 1            | 1           | NO                            |
+
+Changing the `replication_mode` between modes with the same number of replicas
+(e.g. from `3` to `3-degraded`, or from `2-dangerous` to `2`), can be done easily by
+just changing the `replication_mode` parameter in your config files and restarting all your
+Garage nodes.
+
+It is also technically possible to change the replication mode to a mode with a
+different numbers of replicas, although it's a dangerous operation that is not
+officially supported.  This requires you to delete the existing cluster layout
+and create a new layout from scratch, meaning that a full rebalancing of your
+cluster's data will be needed.  To do it, shut down your cluster entirely,
+delete the `custer_layout` files in the meta directories of all your nodes,
+update all your configuration files with the new `replication_mode` parameter,
+restart your cluster, and then create a new layout with all the nodes you want
+to keep.  Rebalancing data will take some time, and data might temporarily
+appear unavailable to your users.  It is recommended to shut down public access
+to the cluster while rebalancing is in progress.  In theory, no data should be
+lost as rebalancing is a routine operation for Garage, although we cannot
+guarantee you that everything will go right in such an extreme scenario.
+
+### `compression_level`
+
+Zstd compression level to use for storing blocks.
+
+Values between `1` (faster compression) and `19` (smaller file) are standard compression
+levels for zstd. From `20` to `22`, compression levels are referred as "ultra" and must be
+used with extra care as it will use lot of memory. A value of `0` will let zstd choose a
+default value (currently `3`). Finally, zstd has also compression designed to be faster
+than default compression levels, they range from `-1` (smaller file) to `-99` (faster 
+compression).
+
+If you do not specify a `compression_level` entry, Garage will set it to `1` for you. With
+this parameters, zstd consumes low amount of cpu and should work faster than line speed in
+most situations, while saving some space and intra-cluster
+bandwidth.
+
+If you want to totally deactivate zstd in Garage, you can pass the special value `'none'`. No
+zstd related code will be called, your chunks will be stored on disk without any processing.
+
+Compression is done synchronously, setting a value too high will add latency to write queries.
+
+This value can be different between nodes, compression is done by the node which receive the
+API call.
+
+### `rpc_secret`
+
+Garage uses a secret key that is shared between all nodes of the cluster
+in order to identify these nodes and allow them to communicate together.
+This key should be specified here in the form of a 32-byte hex-encoded
+random string. Such a string can be generated with a command
+such as `openssl rand -hex 32`.
+
+### `rpc_bind_addr`
+
+The address and port on which to bind for inter-cluster communcations
+(reffered to as RPC for remote procedure calls).
+The port specified here should be the same one that other nodes will used to contact
+the node, even in the case of a NAT: the NAT should be configured to forward the external
+port number to the same internal port nubmer. This means that if you have several nodes running
+behind a NAT, they should each use a different RPC port number.
+
+### `rpc_public_addr`
+
+The address and port that other nodes need to use to contact this node for
+RPC calls.  **This parameter is optional but recommended.** In case you have
+a NAT that binds the RPC port to a port that is different on your public IP,
+this field might help making it work.
+
+### `bootstrap_peers`
+
+A list of peer identifiers on which to contact other Garage peers of this cluster.
+These peer identifiers have the following syntax:
+
+```
+<node public key>@<node public IP or hostname>:<port>
+```
+
+In the case where `rpc_public_addr` is correctly specified in the
+configuration file, the full identifier of a node including IP and port can
+be obtained by running `garage node id` and then included directly in the
+`bootstrap_peers` list of other nodes.  Otherwise, only the node's public
+key will be returned by `garage node id` and you will have to add the IP
+yourself.
+
+### `consul_host` and `consul_service_name`
+
+Garage supports discovering other nodes of the cluster using Consul.  For this
+to work correctly, nodes need to know their IP address by which they can be
+reached by other nodes of the cluster, which should be set in `rpc_public_addr`.
+
+The `consul_host` parameter should be set to the hostname of the Consul server,
+and `consul_service_name` should be set to the service name under which Garage's
+RPC ports are announced.
+
+Garage does not yet support talking to Consul over TLS.
+
+### `kubernetes_namespace`, `kubernetes_service_name` and `kubernetes_skip_crd`
+
+Garage supports discovering other nodes of the cluster using kubernetes custom
+resources. For this to work `kubernetes_namespace` and `kubernetes_service_name`
+need to be configured.
+
+`kubernetes_namespace` sets the namespace in which the custom resources are
+configured. `kubernetes_service_name` is added as a label to these resources to
+filter them, to allow for multiple deployments in a single namespace.
+
+`kubernetes_skip_crd` can be set to true to disable the automatic creation and
+patching of the `garagenodes.deuxfleurs.fr` CRD. You will need to create the CRD
+manually.
+
+### `sled_cache_capacity`
+
+This parameter can be used to tune the capacity of the cache used by
+[sled](https://sled.rs), the database Garage uses internally to store metadata.
+Tune this to fit the RAM you wish to make available to your Garage instance.
+This value has a conservative default (128MB) so that Garage doesn't use too much
+RAM by default, but feel free to increase this for higher performance.
+
+### `sled_flush_every_ms`
+
+This parameters can be used to tune the flushing interval of sled.
+Increase this if sled is thrashing your SSD, at the risk of losing more data in case
+of a power outage (though this should not matter much as data is replicated on other
+nodes). The default value, 2000ms, should be appropriate for most use cases.
+
+
+
+## The `[s3_api]` section
+
+### `api_bind_addr`
+
+The IP and port on which to bind for accepting S3 API calls.
+This endpoint does not suport TLS: a reverse proxy should be used to provide it.
+
+### `s3_region`
+
+Garage will accept S3 API calls that are targetted to the S3 region defined here.
+API calls targetted to other regions will fail with a AuthorizationHeaderMalformed error
+message that redirects the client to the correct region.
+
+### `root_domain` {#root_domain}
+
+The optionnal suffix to access bucket using vhost-style in addition to path-style request.
+Note path-style requests are always enabled, whether or not vhost-style is configured.
+Configuring vhost-style S3 required a wildcard DNS entry, and possibly a wildcard TLS certificate,
+but might be required by softwares not supporting path-style requests.
+
+If `root_domain` is `s3.garage.eu`, a bucket called `my-bucket` can be interacted with
+using the hostname `my-bucket.s3.garage.eu`.
+
+
+
+## The `[s3_web]` section
+
+Garage allows to publish content of buckets as websites. This section configures the
+behaviour of this module.
+
+### `bind_addr`
+
+The IP and port on which to bind for accepting HTTP requests to buckets configured
+for website access.
+This endpoint does not suport TLS: a reverse proxy should be used to provide it.
+
+### `root_domain`
+
+The optionnal suffix appended to bucket names for the corresponding HTTP Host.
+
+For instance, if `root_domain` is `web.garage.eu`, a bucket called `deuxfleurs.fr`
+will be accessible either with hostname `deuxfleurs.fr.web.garage.eu`
+or with hostname `deuxfleurs.fr`.
+
+
+## The `[admin]` section
+
+Garage has a few administration capabilities, in particular to allow remote monitoring. These features are detailed below.
+
+### `api_bind_addr`
+
+If specified, Garage will bind an HTTP server to this port and address, on
+which it will listen to requests for administration features.
+See [administration API reference](@/documentation/reference-manual/admin-api.md) to learn more about these features.
+
+### `metrics_token` (since version 0.7.2)
+
+The token for accessing the Metrics endpoint. If this token is not set in
+the config file, the Metrics endpoint can be accessed without access
+control.
+
+You can use any random string for this value. We recommend generating a random token with `openssl rand -hex 32`.
+
+### `admin_token` (since version 0.7.2)
+
+The token for accessing all of the other administration endpoints.  If this
+token is not set in the config file, access to these endpoints is disabled
+entirely.
+
+You can use any random string for this value. We recommend generating a random token with `openssl rand -hex 32`.
+
+### `trace_sink`
+
+Optionnally, the address of an Opentelemetry collector.  If specified,
+Garage will send traces in the Opentelemetry format to this endpoint. These
+trace allow to inspect Garage's operation when it handles S3 API requests.

+
+Starting with version 0.7.2, Garage introduces an optionnal feature, K2V,
+which is an alternative storage API designed to help efficiently store
+many small values in buckets (in opposition to S3 which is more designed
+to store large blobs).
+
+K2V is currently disabled at compile time in all builds, as the
+specification is still subject to changes. To build a Garage version with
+K2V, the Cargo feature flag `k2v` must be activated.  Special builds with
+the `k2v` feature flag enabled can be obtained from our download page under
+"Extra builds": such builds can be identified easily as their tag name ends
+with `-k2v` (example: `v0.7.2-k2v`).
+
+The specification of the K2V API can be found
+[here](https://git.deuxfleurs.fr/Deuxfleurs/garage/src/branch/k2v/doc/drafts/k2v-spec.md).
+This document also includes a high-level overview of K2V's design.
+
+The K2V API uses AWSv4 signatures for authentification, same as the S3 API.
+The AWS region used for signature calculation is always the same as the one
+defined for the S3 API in the config file.
+
+## Enabling and using K2V
+
+To enable K2V, download and run a build that has the `k2v` feature flag
+enabled, or produce one yourself. Then, add the following section to your
+configuration file:
+
+```toml
+[k2v_api]
+api_bind_addr = "<ip>:<port>"
+```
+
+Please select a port number that is not already in use by another API
+endpoint (S3 api, admin API) or by the RPC server.
+
+We provide an early-stage K2V client library for Rust which can be imported by adding the following to your `Cargo.toml` file:
+
+```toml
+k2v-client = { git = "https://git.deuxfleurs.fr/Deuxfleurs/garage.git" }
+```
+
+There is also a simple CLI utility which can be built from source in the
+following way:
+
+```sh
+git clone https://git.deuxfleurs.fr/Deuxfleurs/garage.git
+cd garage/src/k2v-client
+cargo build --features cli --bin k2v-cli
+```
+
+The CLI utility is self-documented, run `k2v-cli --help` to learn how to use
+it. There is also a short README.md in the `src/k2v-client` folder with some
+instructions.

 The cluster layout in Garage is a table that assigns to each node a role in
 the cluster. The role of a node in Garage can either be a storage node with
 a certain capacity, or a gateway node that does not store data and is only
 used as an API entry point for faster cluster access.

+
+Data retrieval requests to Garage endpoints (S3 API and websites) are resolved 
+to an individual object in a bucket. Since objects are replicated to multiple nodes 
+Garage must ensure consistency before answering the request.
+
+## Using quorum to ensure consistency
+
+Garage ensures consistency by attempting to establish a quorum with the
+data nodes responsible for the object. When a majority of the data nodes
+have provided metadata on a object Garage can then answer the request.
+
+When a request arrives Garage will, assuming the recommended 3 replicas, perform the following actions:
+
+- Make a request to the two preferred nodes for object metadata
+- Try the third node if one of the two initial requests fail
+- Check that the metadata from at least 2 nodes match
+- Check that the object hasn't been marked deleted
+- Answer the request with inline data from metadata if object is small enough
+- Or get data blocks from the preferred nodes and answer using the assembled object
+
+Garage dynamically determines which nodes to query based on health, preference, and 
+which nodes actually host a given data. Garage has no concept of "primary" so any 
+healthy node with the data can be used as long as a quorum is reached for the metadata.
+
+## Node health
+
+Garage keeps a TCP session open to each node in the cluster and periodically pings them. If a connection
+cannot be established, or a node fails to answer a number of pings, the target node is marked as failed.
+Failed nodes are not used for quorum or other internal requests.
+
+## Node preference
+
+Garage prioritizes which nodes to query according to a few criteria:
+
+- A node always prefers itself if it can answer the request
+- Then the node prioritizes nodes in the same zone
+- Finally the nodes with the lowest latency are prioritized 
+
+

+
+**ListObjects:** Implemented, but there isn't a very good specification of what
+`encoding-type=url` covers so there might be some encoding bugs. In our
+implementation the url-encoded fields are in the same in ListObjects as they
+are in ListObjectsV2.
+
+*Note: Ceph API documentation is incomplete and lacks at least HeadBucket and UploadPartCopy,
+but these endpoints are documented in [Red Hat Ceph Storage - Chapter 2. Ceph Object Gateway and the S3 API](https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/4/html/developer_guide/ceph-object-gateway-and-the-s3-api)*

+
+**PutBucketWebsite:** Implemented, but only stores the index document suffix and the error document path. Redirects are not supported.
+
+*Note: Ceph radosgw has some support for static websites but it is different from the Amazon one. It also does not implement its configuration endpoints.*
+
+### ACL, Policies endpoints
+
+Amazon has 2 access control mechanisms in S3: ACL (legacy) and policies (new one).
+Garage implements none of them, and has its own system instead, built around a per-access-key-per-bucket logic.
+See Garage CLI reference manual to learn how to use Garage's permission system.

+
+### Versioning, Lifecycle endpoints
+
+Garage does not (yet) support object versioning.
+If you need this feature, please [share your use case in our dedicated issue](https://git.deuxfleurs.fr/Deuxfleurs/garage/issues/166).
+
+| Endpoint                     | Garage                           | [Openstack Swift](https://docs.openstack.org/swift/latest/s3_compat.html) | [Ceph Object Gateway](https://docs.ceph.com/en/latest/radosgw/s3/) | [Riak CS](https://docs.riak.com/riak/cs/2.1.1/references/apis/storage/s3/index.html) | [OpenIO](https://docs.openio.io/latest/source/arch-design/s3_compliancy.html) |

+
+
+**GetBucketVersioning:** Stub implementation (Garage does not yet support versionning so this always returns "versionning not enabled").
+
+### Replication endpoints
+
+Please open an issue if you have a use case for replication.
+
+| Endpoint                     | Garage                           | [Openstack Swift](https://docs.openstack.org/swift/latest/s3_compat.html) | [Ceph Object Gateway](https://docs.ceph.com/en/latest/radosgw/s3/) | [Riak CS](https://docs.riak.com/riak/cs/2.1.1/references/apis/storage/s3/index.html) | [OpenIO](https://docs.openio.io/latest/source/arch-design/s3_compliancy.html) |

+
+*Note: Ceph documentation briefly says that Ceph supports
+[replication through the S3 API](https://docs.ceph.com/en/latest/radosgw/multisite-sync-policy/#s3-replication-api)
+but with some limitations.
+Additionaly, replication endpoints are not documented in the S3 compatibility page so I don't know what kind of support we can expect.*
+
+### Locking objects
+
+Amazon defines a concept of [object locking](https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-lock.html) that can be achieved either through a Retention period or a Legal hold.

-# Backups (restic, duplicity...)
-
-Backups are essential for disaster recovery but they are not trivial to manage.
-Using Garage as your backup target will enable you to scale your storage as needed while ensuring high availability.
-
-## Borg Backup
-
-Borg Backup is very popular among the backup tools but it is not yet compatible with the S3 API.
-We recommend using any other tool listed in this guide because they are all compatible with the S3 API.
-If you still want to use Borg, you can use it with `rclone mount`.

-# CLI tools
-
-CLI tools allow you to query the S3 API without too many abstractions.
-These tools are particularly suitable for debug, backups, website deployments or any scripted task that need to handle data.
-
-## Minio client (recommended)
-
-Use the following command to set an "alias", i.e. define a new S3 server to be
-used by the Minio client:
-
-```bash
-mc alias set \
-  garage \
-  <endpoint> \
-  <access key> \
-  <secret key> \
-  --api S3v4
-```
-
-Remember that `mc` is sometimes called `mcli` (such as on Arch Linux), to avoid conflicts
-with Midnight Commander.
-
-Some commands:
-
-```bash
-# list buckets
-mc ls garage/
-
-# list objets in a bucket
-mc ls garage/my_files
-
-# copy from your filesystem to garage
-mc cp /proc/cpuinfo garage/my_files/cpuinfo.txt
-
-# copy from garage to your filesystem
-mc cp garage/my_files/cpuinfo.txt /tmp/cpuinfo.txt
-
-# mirror a folder from your filesystem to garage
-mc mirror --overwrite ./book garage/garagehq.deuxfleurs.fr
-```
-
-
-## AWS CLI
-
-Create a file named `~/.aws/credentials` and put:
-
-```toml
-[default]
-aws_access_key_id=xxxx
-aws_secret_access_key=xxxx
-```
-
-Then a file named `~/.aws/config` and put:
-
-```toml
-[default]
-region=garage
-```
-
-Now, supposing Garage is listening on `http://127.0.0.1:3900`, you can list your buckets with:
-
-```bash
-aws --endpoint-url http://127.0.0.1:3900 s3 ls
-```
-
-Passing the `--endpoint-url` parameter to each command is annoying but AWS developers do not provide a corresponding configuration entry.
-As a workaround, you can redefine the aws command by editing the file `~/.bashrc`:
-
-```
-function aws { command aws --endpoint-url http://127.0.0.1:3900 $@ ; }
-```
-
-*Do not forget to run `source ~/.bashrc` or to start a new terminal before running the next commands.*
-
-Now you can simply run:
-
-```bash
-# list buckets
-aws s3 ls
-
-# list objects of a bucket
-aws s3 ls s3://my_files
-
-# copy from your filesystem to garage
-aws s3 cp /proc/cpuinfo s3://my_files/cpuinfo.txt
-
-# copy from garage to your filesystem
-aws s3 cp s3/my_files/cpuinfo.txt /tmp/cpuinfo.txt
-```
-
-## `rclone`
-
-`rclone` can be configured using the interactive assistant invoked using `rclone config`.
-
-You can also configure `rclone` by writing directly its configuration file.
-Here is a template `rclone.ini` configuration file (mine is located at `~/.config/rclone/rclone.conf`):
-
-```ini
-[garage]
-type = s3
-provider = Other
-env_auth = false
-access_key_id = <access key>
-secret_access_key = <secret key>
-region = <region>
-endpoint = <endpoint>
-force_path_style = true
-acl = private
-bucket_acl = private
-```
-
-Now you can run:
-
-```bash
-# list buckets
-rclone lsd garage:
-
-# list objects of a bucket aggregated in directories
-rclone lsd garage:my-bucket
-
-# copy from your filesystem to garage
-echo hello world > /tmp/hello.txt
-rclone copy /tmp/hello.txt garage:my-bucket/
-
-# copy from garage to your filesystem
-rclone copy garage:quentin.divers/hello.txt .
-
-# see all available subcommands
-rclone help
-```
-
-## `s3cmd`
-
-Here is a template for the `s3cmd.cfg` file to talk with Garage:
-
-```ini
-[default]
-access_key = <access key>
-secret_key = <secret key>
-host_base = <endpoint without http(s)://>
-host_bucket = <same as host_base>
-use_https = <False or True>
-```
-
-And use it as follow:
-
-```bash
-# List buckets
-s3cmd ls
-
-# s3cmd objects inside a bucket
-s3cmd ls s3://my-bucket
-
-# copy from your filesystem to garage
-echo hello world > /tmp/hello.txt
-s3cmd put /tmp/hello.txt s3://my-bucket/
-
-# copy from garage to your filesystem
-s3cmd get s3://my-bucket/hello.txt hello.txt
-```

-# Websites (Hugo, Jekyll, Publii...)
-
-Garage is also suitable to host static websites.
-While they can be deployed with traditional CLI tools, some static website generators have integrated options to ease your workflow.
-
-## Hugo
-
-Add to your `config.toml` the following section:
-
-```toml
-[[deployment.targets]]
- URL = "s3://<bucket>?endpoint=<endpoint>&disableSSL=<bool>&s3ForcePathStyle=true&region=garage"
-```
-
-For example:
-
-```toml
-[[deployment.targets]]
- URL = "s3://my-blog?endpoint=localhost:9000&disableSSL=true&s3ForcePathStyle=true&region=garage"
-```
-
-Then inform hugo of your credentials:
-
-```bash
-export AWS_ACCESS_KEY_ID=GKxxx
-export AWS_SECRET_ACCESS_KEY=xxx
-```
-
-And finally build and deploy your website:
-
-```bsh
-hugo
-hugo deploy
-```

-  - [Hugo Documentation > hugo deploy](https://gohugo.io/hosting-and-deployment/hugo-deploy/)
-
-## Publii
-
-It would require a patch either on Garage or on Publii to make both systems work.
-
-Currently, the proposed workaround is to deploy your website manually:
-  - On the left menu, click on Server, choose Manual Deployment (the logo looks like a compressed file)
-  - Set your website URL, keep Output type as "Non-compressed catalog"
-  - Click on Save changes
-  - Click on Sync your website (bottom left of the app)
-  - On the new page, click again on Sync your website
-  - Click on Get website files
-  - You need to synchronize the output folder you see in your file explorer, we will use minio client.
-
-Be sure that you [configured minio client](cli.html#minio-client-recommended).
-
-Then copy this output folder
-
-```bash
-mc mirror --overwrite output garage/my-site
-```
-
-## Generic (eg. Jekyll)
-
-Some tools do not support sending to a S3 backend but output a compiled folder on your system.
-We can then use any CLI tool to upload this content to our S3 target.
-
-First, start by [configuring minio client](cli.html#minio-client-recommended).
-
-Then build your website:
-
-```bash
-jekyll build
-```
-
-And copy jekyll's output folder on S3:
-
-```bash
-mc mirror --overwrite _site garage/my-site
-```

-# Exposing buckets as websites
-
-You can expose your bucket as a website with this simple command:
-
-```bash
-garage bucket website --allow my-website
-```
-
-Now it will be **publicly** exposed on the web endpoint (by default listening on port 3902).
-
-Our website serving logic is as follow:
-  - Supports only static websites (no support for PHP or other languages)
-  - Does not support directory listing
-  - The index is defined in your `garage.toml`. ([ref](/reference_manual/configuration.html#index))
-
-Now we need to infer the URL of your website through your bucket name.
-Let assume:
-  - we set `root_domain = ".web.example.com"` in `garage.toml` ([ref](/reference_manual/configuration.html#root_domain))
-  - our bucket name is `garagehq.deuxfleurs.fr`.
-
-Our bucket will be served if the Host field matches one of these 2 values (the port is ignored):
-
-  - `garagehq.deuxfleurs.fr.web.example.com`: you can dedicate a subdomain to your users (here `web.example.com`).
-
-  - `garagehq.deuxfleurs.fr`: your users can bring their own domain name, they just need to point them to your Garage cluster.
-
-You can try this logic locally, without configuring any DNS, thanks to `curl`:
-
-```bash
-# prepare your test
-echo hello world > /tmp/index.html
-mc cp /tmp/index.html garage/garagehq.deuxfleurs.fr
-
-curl -H 'Host: garagehq.deuxfleurs.fr' http://localhost:3902
-# should print "hello world"
-
-curl -H 'Host: garagehq.deuxfleurs.fr.web.example.com' http://localhost:3902
-# should also print "hello world"
-```
-
-Now that you understand how website logic works on Garage, you can:
-
- - make the website endpoint listens on port 80 (instead of 3902)
- - use iptables to redirect the port 80 to the port 3902:  
-   `iptables -t nat -A PREROUTING -p tcp -dport 80 -j REDIRECT -to-port 3902`
- - or configure a [reverse proxy](reverse_proxy.html) in front of Garage to add TLS (HTTPS), CORS support, etc.
-
-You can also take a look at [Website Integration](/connect/websites.html) to see how you can add Garage to your workflow.

-# Configuring a reverse proxy
-
-The main reason to add a reverse proxy in front of Garage is to provide TLS to your users.
-
-In production you will likely need your certificates signed by a certificate authority.
-The most automated way is to use a provider supporting the [ACME protocol](https://datatracker.ietf.org/doc/html/rfc8555) 
-such as [Let's Encrypt](https://letsencrypt.org/), [ZeroSSL](https://zerossl.com/) or [Buypass Go SSL](https://www.buypass.com/ssl/products/acme).
-
-If you are only testing Garage, you can generate a self-signed certificate to follow the documentation:
-
-```bash
-openssl req \
-    -new \
-    -x509 \
-    -keyout /tmp/garage.key \
-    -out /tmp/garage.crt \
-    -nodes  \
-    -subj "/C=XX/ST=XX/L=XX/O=XX/OU=XX/CN=localhost/emailAddress=X@X.XX" \
-    -addext "subjectAltName = DNS:localhost, IP:127.0.0.1"
-
-cat /tmp/garage.key /tmp/garage.crt > /tmp/garage.pem
-```
-
-Be careful as you will need to allow self signed certificates in your client.
-For example, with minio, you must add the `--insecure` flag.
-An example:
-
-```bash
-mc ls --insecure garage/
-```
-
-## socat (only for testing purposes)
-
-If you want to test Garage with a TLS frontend, socat can do it for you in a single command:
-
-```bash
-socat \
-"openssl-listen:443,\
-reuseaddr,\
-fork,\
-verify=0,\
-cert=/tmp/garage.pem" \
-tcp4-connect:localhost:3900
-```
-
-## Nginx
-
-Nginx is a well-known reverse proxy suitable for production.
-We do the configuration in 3 steps: first we define the upstream blocks ("the backends")
-then we define the server blocks ("the frontends") for the S3 endpoint and finally for the web endpoint.
-
-The following configuration blocks can be all put in the same `/etc/nginx/sites-available/garage.conf`.
-To make your configuration active, run `ln -s /etc/nginx/sites-available/garage.conf /etc/nginx/sites-enabled/`.
-If you directly put the instructions in the root `nginx.conf`, keep in mind that these configurations must be enclosed inside a `http { }` block.
-
-And do not forget to reload nginx with `systemctl reload nginx` or `nginx -s reload`.
-
-### Defining backends
-
-First, we need to tell to nginx how to access our Garage cluster.
-Because we have multiple nodes, we want to leverage all of them by spreading the load.
-
-In nginx, we can do that with the upstream directive.
-Because we have 2 endpoints: one for the S3 API and one to serve websites,
-we create 2 backends named respectively `s3_backend` and `web_backend`.
-
-A documented example for the `s3_backend` assuming you chose port 3900:
-
-```nginx
-upstream s3_backend {
-  # if you have a garage instance locally
-  server 127.0.0.1:3900;
-  # you can also put your other instances
-  server 192.168.1.3:3900;
-  # domain names also work
-  server garage1.example.com:3900;
-  # you can assign weights if you have some servers 
-  # that are more powerful than others
-  server garage2.example.com:3900 weight=2;
-}
-```
-
-A similar example for the `web_backend` assuming you chose port 3902:
-
-```nginx
-upstream web_backend {
-  server 127.0.0.1:3902;
-  server 192.168.1.3:3902;
-  server garage1.example.com:3902;
-  server garage2.example.com:3902 weight=2;
-}
-```
-
-### Exposing the S3 API
-
-The configuration section for the S3 API is simple as we only support path-access style yet.
-We simply configure the TLS parameters and forward all the requests to the backend:
-
-```nginx
-server {
-  listen [::]:443 http2 ssl;
-  ssl_certificate     /tmp/garage.crt;
-  ssl_certificate_key /tmp/garage.key;
-
-  # should be the endpoint you want
-  # aws uses s3.amazonaws.com for example
-  server_name garage.example.com;
-
-  location / {
-    proxy_pass http://s3_backend;
-    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-    proxy_set_header Host $host;
-  }
-}
-
-```
-
-### Exposing the web endpoint
-
-The web endpoint is a bit more complicated to configure as it listens on many different `Host` fields.
-To better understand the logic involved, you can refer to the [Exposing buckets as websites](/cookbook/exposing_websites.html) section.
-Also, for some applications, you may need to serve CORS headers: Garage can not serve them directly but we show how we can use nginx to serve them.
-You can use the following example as your starting point:
-
-```nginx
-server {
-  listen [::]:443 http2 ssl;
-  ssl_certificate     /tmp/garage.crt;
-  ssl_certificate_key /tmp/garage.key;
-
-  # We list all the Hosts fields that can access our buckets
-  server_name *.web.garage
-              example.com
-              my-site.tld
-              ;
-
-  location / {
-    # Add these headers only if you want to allow CORS requests
-    # For production use, more specific rules would be better for your security
-    add_header Access-Control-Allow-Origin *;
-    add_header Access-Control-Max-Age 3600;
-    add_header Access-Control-Expose-Headers Content-Length;
-    add_header Access-Control-Allow-Headers Range;
-
-    # We do not forward OPTIONS requests to Garage
-    # as it does not support them but they are needed for CORS.
-    if ($request_method = OPTIONS) {
-      return 200;
-    }
-
-    proxy_pass http://web_backend;
-    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-    proxy_set_header Host $host;
-  }
-}
-```

-# Data resiliency for everyone
-
-Garage is an **open-source** distributed **storage service** you can **self-host** to fullfill many needs:
-

-
-Garage implements the **[Amazon S3 API](https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html)** and thus is already **compatible** with many applications:
-
-<p align="center" style="text-align:center; margin-bottom: 8rem;">

-
-Garage provides **data resiliency** by **replicating** data 3x over **distant** servers:

-## Keeping requirements low
-
-We worked hard to keep requirements as low as possible as we target the largest possible public.
-
-  * **CPU:** any x86\_64 CPU from the last 10 years, ARMv7 or ARMv8.
-  * **RAM:** 1GB
-  * **Disk Space:** at least 16GB
-  * **Network:** 200ms or less, 50 Mbps or more
-  * **Heterogeneous hardware:** build a cluster with whatever second-hand machines are available
-
-*For the network, as we do not use consensus algorithms like Paxos or Raft, Garage is not as latency sensitive.*
-*Thanks to Rust and its zero-cost abstractions, we keep CPU and memory low.*

-```
-
-The following gives details about each available configuration option.
-
-## Available configuration options
-
-#### `metadata_dir`
-
-The directory in which Garage will store its metadata. This contains the node identifier,
-the network configuration and the peer list, the list of buckets and keys as well
-as the index of all objects, object version and object blocks.
-
-Store this folder on a fast SSD drive if possible to maximize Garage's performance.
-
-#### `data_dir`
-
-The directory in which Garage will store the data blocks of objects.
-This folder can be placed on an HDD. The space available for `data_dir`
-should be counted to determine a node's capacity
-when [configuring it](../getting_started/05_cluster.md).
-
-#### `block_size`
-
-Garage splits stored objects in consecutive chunks of size `block_size`
-(except the last one which might be smaller). The default size is 1MB and
-should work in most cases.  If you are interested in tuning this, feel free
-to do so (and remember to report your findings to us!). If this value is
-changed for a running Garage installation, only files newly uploaded will be
-affected. Previously uploaded files will remain available. This however
-means that chunks from existing files will not be deduplicated with chunks
-from newly uploaded files, meaning you might use more storage space that is
-optimally possible.
-
-#### `replication_mode`
-
-Garage supports the following replication modes:
-
-- `none` or `1`: data stored on Garage is stored on a single node. There is no redundancy,
-  and data will be unavailable as soon as one node fails or its network is disconnected.
-  Do not use this for anything else than test deployments.
-
-- `2`: data stored on Garage will be stored on two different nodes, if possible in different
-  zones. Garage tolerates one node failure before losing data. Data should be available
-  read-only when one node is down, but write operations will fail.
-  Use this only if you really have to.
-
-- `3`: data stored on Garage will be stored on three different nodes, if possible each in
-  a different zones.
-  Garage tolerates two node failure before losing data. Data should be available
-  read-only when two nodes are down, and writes should be possible if only a single node
-  is down.
-
-Note that in modes `2` and `3`,
-if at least the same number of zones are available, an arbitrary number of failures in 
-any given zone is tolerated as copies of data will be spread over several zones.
-
-**Make sure `replication_mode` is the same in the configuration files of all nodes.
-Never run a Garage cluster where that is not the case.**
-
-Changing the `replication_mode` of a cluster might work (make sure to shut down all nodes
-and changing it everywhere at the time), but is not officially supported.
-
-### `compression_level`
-
-Zstd compression level to use for storing blocks.
-
-Values between `1` (faster compression) and `19` (smaller file) are standard compression
-levels for zstd. From `20` to `22`, compression levels are referred as "ultra" and must be
-used with extra care as it will use lot of memory. A value of `0` will let zstd choose a
-default value (currently `3`). Finally, zstd has also compression designed to be faster
-than default compression levels, they range from `-1` (smaller file) to `-99` (faster 
-compression).
-
-If you do not specify a `compression_level` entry, garage will set it to `1` for you. With
-this parameters, zstd consumes low amount of cpu and should work faster than line speed in
-most situations, while saving some space and intra-cluster
-bandwidth.
-
-If you want to totally deactivate zstd in garage, you can pass the special value `'none'`. No
-zstd related code will be called, your chunks will be stored on disk without any processing.
-
-Compression is done synchronously, setting a value too high will add latency to write queries.
-
-This value can be different between nodes, compression is done by the node which receive the
-API call.
-
-#### `rpc_secret`
-
-Garage uses a secret key that is shared between all nodes of the cluster
-in order to identify these nodes and allow them to communicate together.
-This key should be specified here in the form of a 32-byte hex-encoded
-random string. Such a string can be generated with a command
-such as `openssl rand -hex 32`.
-
-#### `rpc_bind_addr`
-
-The address and port on which to bind for inter-cluster communcations
-(reffered to as RPC for remote procedure calls).
-The port specified here should be the same one that other nodes will used to contact
-the node, even in the case of a NAT: the NAT should be configured to forward the external
-port number to the same internal port nubmer. This means that if you have several nodes running
-behind a NAT, they should each use a different RPC port number.
-
-#### `rpc_public_addr`
-
-The address and port that other nodes need to use to contact this node for
-RPC calls.  **This parameter is optional but recommended.** In case you have
-a NAT that binds the RPC port to a port that is different on your public IP,
-this field might help making it work.
-
-#### `bootstrap_peers`
-
-A list of peer identifiers on which to contact other Garage peers of this cluster.
-These peer identifiers have the following syntax:
-
-```
-<node public key>@<node public IP or hostname>:<port>
-```
-
-In the case where `rpc_public_addr` is correctly specified in the
-configuration file, the full identifier of a node including IP and port can
-be obtained by running `garage node id` and then included directly in the
-`bootstrap_peers` list of other nodes.  Otherwise, only the node's public
-key will be returned by `garage node id` and you will have to add the IP
-yourself.
-
-#### `consul_host` and `consul_service_name`
-
-Garage supports discovering other nodes of the cluster using Consul.
-This works only when nodes are announced in Consul by an orchestrator such as Nomad,
-as Garage is not able to announce itself.
-
-The `consul_host` parameter should be set to the hostname of the Consul server,
-and `consul_service_name` should be set to the service name under which Garage's
-RPC ports are announced.
-
-#### `sled_cache_capacity`
-
-This parameter can be used to tune the capacity of the cache used by
-[sled](https://sled.rs), the database Garage uses internally to store metadata.
-Tune this to fit the RAM you wish to make available to your Garage instance.
-More cache means faster Garage, but the default value (128MB) should be plenty
-for most use cases.
-
-#### `sled_flush_every_ms`
-
-This parameters can be used to tune the flushing interval of sled.
-Increase this if sled is thrashing your SSD, at the risk of losing more data in case
-of a power outage (though this should not matter much as data is replicated on other
-nodes). The default value, 2000ms, should be appropriate for most use cases.
-
-
-## The `[s3_api]` section
-
-#### `api_bind_addr`
-
-The IP and port on which to bind for accepting S3 API calls.
-This endpoint does not suport TLS: a reverse proxy should be used to provide it.
-
-#### `s3_region`
-
-Garage will accept S3 API calls that are targetted to the S3 region defined here.
-API calls targetted to other regions will fail with a AuthorizationHeaderMalformed error
-message that redirects the client to the correct region.
-
-#### `root_domain`
-
-The optionnal suffix to access bucket using vhost-style in addition to path-style request.
-Note path-style requests are always enabled, whether or not vhost-style is configured.
-Configuring vhost-style S3 required a wildcard DNS entry, and possibly a wildcard TLS certificate,
-but might be required by softwares not supporting path-style requests.
-
-If `root_domain` is `s3.garage.eu`, a bucket called `my-bucket` can be interacted with
-using the hostname `my-bucket.s3.garage.eu`.
-
-## The `[s3_web]` section
-
-Garage allows to publish content of buckets as websites. This section configures the
-behaviour of this module.
-
-#### `bind_addr`
-
-The IP and port on which to bind for accepting HTTP requests to buckets configured
-for website access.
-This endpoint does not suport TLS: a reverse proxy should be used to provide it.
-
-#### `root_domain`
-
-The optionnal suffix appended to bucket names for the corresponding HTTP Host.
-
-For instance, if `root_domain` is `web.garage.eu`, a bucket called `deuxfleurs.fr`
-will be accessible either with hostname `deuxfleurs.fr.web.garage.eu`
-or with hostname `deuxfleurs.fr`.
-
-#### `index`
-
-The name of the index file to return for requests ending with `/` (usually `index.html`).

+
+Garage v0.6 introduces a new data model for buckets,
+that allows buckets to have many names (aliases).
+Buckets can also have "private" aliases (called local aliases),
+which are only visible when using a certain access key.
+
+This new data model means that the metadata tables have changed quite a bit in structure,
+and a manual migration step is required.
+
+The migration steps are as follows:
+
+1. Disable api and web access for some time (Garage does not support disabling
+   these endpoints but you can change the port number or stop your reverse
+   proxy for instance).
+
+2. Do `garage repair -a --yes tables` and `garage repair -a --yes blocks`,
+   check the logs and check that all data seems to be synced correctly between
+   nodes.
+
+4. Turn off Garage 0.5
+
+5. **Backup your metadata folders!!**
+
+6. Turn on Garage 0.6
+
+7. At this point, `garage bucket list` should indicate that no buckets are present
+   in the cluster. `garage key list` should show all of the previously existing
+   access key, however these keys should not have any permissions to access buckets.
+
+8. Run `garage migrate buckets050`: this will populate the new bucket table with
+   the buckets that existed previously. This will also give access to API keys
+   as it was before.
+
+9. Do `garage repair -a --yes tables` and `garage repair -a --yes blocks`,
+   check the logs and check that all data seems to be synced correctly between
+   nodes.
+
+10. Check that all your buckets indeed appear in `garage bucket list`, and that
+    keys have the proper access flags set. If that is not the case, revert
+    everything and file a bug!
+
+11. Your upgraded cluster should be in a working state. Re-enable API and Web
+    access and check that everything went well.

+# Specification of the Garage K2V API (K2V = Key/Key/Value)
+
+- We are storing triplets of the form `(partition key, sort key, value)` -> no
+  user-defined fields, the client is responsible of writing whatever he wants
+  in the value (typically an encrypted blob). Values are binary blobs, which
+  are always represented as their base64 encoding in the JSON API. Partition
+  keys and sort keys are utf8 strings.
+
+- Triplets are stored in buckets; each bucket stores a separate set of triplets
+
+- Bucket names and access keys are the same as for accessing the S3 API
+
+- K2V triplets exist separately from S3 objects. K2V triplets don't exist for
+  the S3 API, and S3 objects don't exist for the K2V API.
+
+- Values stored for triplets have associated causality information, that enables
+  Garage to detect concurrent writes. In case of concurrent writes, Garage
+  keeps the concurrent values until a further write supersedes the concurrent
+  values. This is the same method as Riak KV implements. The method used is
+  based on DVVS (dotted version vector sets), described in the paper "Scalable
+  and Accurate Causality Tracking for Eventually Consistent Data Stores", as
+  well as [here](https://github.com/ricardobcl/Dotted-Version-Vectors)
+
+
+## Data format
+
+### Triple format
+
+Triples in K2V are constituted of three fields:
+
+- a partition key (`pk`), an utf8 string that defines in what partition the
+  triplet is stored; triplets in different partitions cannot be listed together
+  in a ReadBatch command, or deleted together in a DeleteBatch command: a
+  separate command must be included in the ReadBatch/DeleteBatch call for each
+  partition key in which the client wants to read/delete lists of items
+
+- a sort key (`sk`), an utf8 string that defines the index of the triplet inside its
+  partition; triplets are uniquely idendified by their partition key + sort key
+
+- a value (`v`), an opaque binary blob associated to the partition key + sort key;
+  they are transmitted as binary when possible but in most case in the JSON API
+  they will be represented as strings using base64 encoding; a value can also
+  be `null` to indicate a deleted triplet (a `null` value is called a tombstone)
+
+### Causality information
+
+K2V supports storing several concurrent values associated to a pk+sk, in the
+case where insertion or deletion operations are detected to be concurrent (i.e.
+there is not one that was aware of the other, they are not causally dependant
+one on the other).  In practice, it even looks more like the opposite: to
+overwrite a previously existing value, the client must give a "causality token"
+that "proves" (not in a cryptographic sense) that it had seen a previous value.
+Otherwise, the value written will not overwrite an existing value, it will just
+create a new concurrent value.
+
+The causality token is a binary/b64-encoded representation of a context,
+specified below.
+
+A set of concurrent values looks like this:
+
+```
+(node1, tdiscard1, (v1, t1), (v2, t2)) ; tdiscard1 < t1 < t2
+(node2, tdiscard2, (v3, t3)            ; tdiscard2 < t3
+```
+
+`tdiscard` for a node `i` means that all values inserted by node `i` with times
+`<= tdiscard` are obsoleted, i.e. have been read by a client that overwrote it
+afterwards.
+
+The associated context would be the following: `[(node1, t2), (node2, t3)]`,
+i.e. if a node reads this set of values and inserts a new values, we will now
+have `tdiscard1 = t2` and `tdiscard2 = t3`, to indicate that values v1, v2 and v3
+are obsoleted by the new write.
+
+**Basic insertion.** To insert a new value `v4` with context `[(node1, t2), (node2, t3)]`, in a
+simple case where there was no insertion in-between reading the value
+mentionned above and writing `v4`, and supposing that node2 receives the
+InsertItem query:
+
+- `node2` generates a timestamp `t4` such that `t4 > t3`.
+- the new state is as follows:
+
+```
+(node1, tdiscard1', ())       ; tdiscard1' = t2
+(node2, tdiscard2', (v4, t4)) ; tdiscard2' = t3
+```
+
+**A more complex insertion example.** In the general case, other intermediate values could have
+been written before `v4` with context `[(node1, t2), (node2, t3)]` is sent to the system.
+For instance, here is a possible sequence of events:
+
+1. First we have the set of values v1, v2 and v3 described above.
+   A node reads it, it obtains values v1, v2 and v3 with context `[(node1, t2), (node2, t3)]`.
+
+2. A node writes a value `v5` with context `[(node1, t1)]`, i.e. `v5` is only a
+   successor of v1 but not of v2 or v3. Suppose node1 receives the write, it
+   will generate a new timestamp `t5` larger than all of the timestamps it
+   knows of, i.e. `t5 > t2`. We will now have:
+
+```
+(node1, tdiscard1'', (v2, t2), (v5, t5)) ; tdiscard1'' = t1 < t2 < t5
+(node2, tdiscard2, (v3, t3)              ; tdiscard2 < t3
+```
+
+3. Now `v4` is written with context `[(node1, t2), (node2, t3)]`, and node2
+   processes the query. It will generate `t4 > t3` and the state will become:
+
+```
+(node1, tdiscard1', (v5, t5))       ; tdiscard1' = t2 < t5
+(node2, tdiscard2', (v4, t4))       ; tdiscard2' = t3
+```
+
+**Generic algorithm for handling insertions:** A certain node n handles the
+InsertItem and is responsible for the correctness of this procedure.
+
+1. Lock the key (or the whole table?) at this node to prevent concurrent updates of the value that would mess things up
+2. Read current set of values
+3. Generate a new timestamp that is larger than the largest timestamp for node n
+4. Add the inserted value in the list of values of node n
+5. Update the discard times to be the times set in the context, and accordingly discard overwritten values
+6. Release lock
+7. Propagate updated value to other nodes
+8. Return to user when propagation achieved the write quorum (propagation to other nodes continues asynchronously)
+
+**Encoding of contexts:**
+
+Contexts consist in a list of (node id, timestamp) pairs.
+They are encoded in binary as follows:
+
+```
+checksum: u64, [ node: u64, timestamp: u64 ]*
+```
+
+The checksum is just the XOR of all of the node IDs and timestamps.
+
+Once encoded in binary, contexts are written and transmitted in base64.
+
+
+### Indexing
+
+K2V keeps an index, a secondary data structure that is updated asynchronously,
+that keeps tracks of the number of triplets stored for each partition key.
+This allows easy listing of all of the partition keys for which triplets exist
+in a bucket, as the partition key becomes the sort key in the index.
+
+How indexing works:
+
+- Each node keeps a local count of how many items it stores for each partition,
+  in a local Sled tree that is updated atomically when an item is modified.
+- These local counters are asynchronously stored in the index table which is
+  a regular Garage table spread in the network. Counters are stored as LWW values,
+  so basically the final table will have the following structure:
+
+```
+- pk: bucket
+- sk: partition key for which we are counting
+- v:  lwwmap (node id -> number of items)
+```
+
+The final number of items present in the partition can be estimated by taking
+the maximum of the values (i.e. the value for the node that announces having
+the most items for that partition). In most cases the values for different node
+IDs should all be the same; more precisely, three node IDs should map to the
+same non-zero value, and all other node IDs that are present are tombstones
+that map to zeroes.  Note that we need to filter out values from nodes that are
+no longer part of the cluster layout, as when nodes are removed they won't
+necessarily have had the time to set their counters to zero.
+
+## Important details
+
+**THIS SECTION CONTAINS A FEW WARNINGS ON THE K2V API WHICH ARE IMPORTANT
+TO UNDERSTAND IN ORDER TO USE IT CORRECTLY.**
+
+- **Internal server errors on updates do not mean that the update isn't stored.**
+  K2V will return an internal server error when it cannot reach a quorum of nodes on
+  which to save an updated value. However the value may still be stored on just one
+  node, which will then propagate it to other nodes asynchronously via anti-entropy.
+
+- **Batch operations are not transactions.** When calling InsertBatch or DeleteBatch,
+  items may appear partially inserted/deleted while the operation is being processed.
+  More importantly, if InsertBatch or DeleteBatch returns an internal server error,
+  some of the items to be inserted/deleted might end up inserted/deleted on the server,
+  while others may still have their old value.
+
+- **Concurrent values are deduplicated.** When inserting a value for a key,
+  Garage might internally end up
+  storing the value several times if there are network errors. These values will end up as
+  concurrent values for a key, with the same byte string (or `null` for a deletion).
+  Garage fixes this by deduplicating concurrent values when they are returned to the
+  user on read operations. Importantly, *Garage does not differentiate between duplicate
+  concurrent values due to the user making the same call twice, or Garage having to
+  do an internal retry*. This means that all duplicate concurrent values are deduplicated
+  when an item is read: if the user inserts twice concurrently the same value, they will
+  only read it once.
+
+## API Endpoints
+
+**Remark.** Example queries and responses here are given in JSON5 format
+for clarity. However the actual K2V API uses basic JSON so all examples
+and responses need to be translated.
+
+### Operations on single items
+
+**ReadItem: `GET /<bucket>/<partition key>?sort_key=<sort key>`**
+
+
+Query parameters:
+
+| name | default value | meaning |
+| - | - | - |
+| `sort_key` | **mandatory** | The sort key of the item to read |
+
+Returns the item with specified partition key and sort key. Values can be
+returned in either of two ways:
+
+1. a JSON array of base64-encoded values, or `null`'s for tombstones, with
+   header `Content-Type: application/json`
+
+2. in the case where there are no concurrent values, the single present value
+   can be returned directly as the response body (or an HTTP 204 NO CONTENT for
+   a tombstone), with header `Content-Type: application/octet-stream`
+
+The choice between return formats 1 and 2 is directed by the `Accept` HTTP header:
+
+- if the `Accept` header is not present, format 1 is always used
+
+- if `Accept` contains `application/json` but not `application/octet-stream`,
+  format 1 is always used
+
+- if `Accept` contains `application/octet-stream` but not `application/json`,
+  format 2 is used when there is a single value, and an HTTP error 409 (HTTP
+  409 CONFLICT) is returned in the case of multiple concurrent values
+  (including concurrent tombstones)
+
+- if `Accept` contains both, format 2 is used when there is a single value, and
+  format 1 is used as a fallback in case of concurrent values
+
+- if `Accept` contains none, HTTP 406 NOT ACCEPTABLE is raised
+
+Example query:
+
+```
+GET /my_bucket/mailboxes?sort_key=INBOX HTTP/1.1
+```
+
+Example response:
+
+```json
+HTTP/1.1 200 OK
+X-Garage-Causality-Token: opaquetoken123
+Content-Type: application/json
+
+[
+  "b64cryptoblob123",
+  "b64cryptoblob'123"
+]
+```
+
+Example response in case the item is a tombstone:
+
+```
+HTTP/1.1 200 OK
+X-Garage-Causality-Token: opaquetoken999
+Content-Type: application/json
+
+[
+  null
+]
+```
+
+Example query 2:
+
+```
+GET /my_bucket/mailboxes?sort_key=INBOX HTTP/1.1
+Accept: application/octet-stream
+```
+
+Example response if multiple concurrent versions exist:
+
+```
+HTTP/1.1 409 CONFLICT
+X-Garage-Causality-Token: opaquetoken123
+Content-Type: application/octet-stream
+```
+
+Example response in case of single value:
+
+```
+HTTP/1.1 200 OK
+X-Garage-Causality-Token: opaquetoken123
+Content-Type: application/octet-stream
+
+cryptoblob123
+```
+
+Example response in case of a single value that is a tombstone:
+
+```
+HTTP/1.1 204 NO CONTENT
+X-Garage-Causality-Token: opaquetoken123
+Content-Type: application/octet-stream
+```
+
+
+**PollItem: `GET /<bucket>/<partition key>?sort_key=<sort key>&causality_token=<causality token>`**
+
+This endpoint will block until a new value is written to a key.
+
+The GET parameter `causality_token` should be set to the causality
+token returned with the last read of the key, so that K2V knows
+what values are concurrent or newer than the ones that the
+client previously knew.
+
+This endpoint returns the new value in the same format as ReadItem.
+If no new value is written and the timeout elapses,
+an HTTP 304 NOT MODIFIED is returned.
+
+Query parameters:
+
+| name | default value | meaning |
+| - | - | - |
+| `sort_key` | **mandatory** | The sort key of the item to read |
+| `causality_token` | **mandatory** | The causality token of the last known value or set of values |
+| `timeout` | 300 | The timeout before 304 NOT MODIFIED is returned if the value isn't updated |
+
+The timeout can be set to any number of seconds, with a maximum of 600 seconds (10 minutes).
+
+
+**InsertItem: `PUT /<bucket>/<partition key>?sort_key=<sort_key>`**
+
+Inserts a single item. This request does not use JSON, the body is sent directly as a binary blob.
+
+To supersede previous values, the HTTP header `X-Garage-Causality-Token` should
+be set to the causality token returned by a previous read on this key. This
+header can be ommitted for the first writes to the key.
+
+Example query:
+
+```
+PUT /my_bucket/mailboxes?sort_key=INBOX HTTP/1.1
+X-Garage-Causality-Token: opaquetoken123
+
+myblobblahblahblah
+```
+
+Example response:
+
+```
+HTTP/1.1 200 OK
+```
+
+**DeleteItem: `DELETE /<bucket>/<partition key>?sort_key=<sort_key>`**
+
+Deletes a single item. The HTTP header `X-Garage-Causality-Token` must be set
+to the causality token returned by a previous read on this key, to indicate
+which versions of the value should be deleted. The request will not process if
+`X-Garage-Causality-Token` is not set.
+
+Example query:
+
+```
+DELETE /my_bucket/mailboxes?sort_key=INBOX HTTP/1.1
+X-Garage-Causality-Token: opaquetoken123
+```
+
+Example response:
+
+```
+HTTP/1.1 204 NO CONTENT
+```
+
+### Operations on index
+
+**ReadIndex: `GET /<bucket>?start=<start>&end=<end>&limit=<limit>`**
+
+Lists all partition keys in the bucket for which some triplets exist, and gives
+for each the number of triplets, total number of values (which might be bigger
+than the number of triplets in case of conflicts), total number of bytes of
+these values, and number of triplets that are in a state of conflict.
+The values returned are an approximation of the true counts in the bucket,
+as these values are asynchronously updated, and thus eventually consistent.
+
+Query parameters:
+
+| name | default value | meaning |
+| - | - | - |
+| `prefix` | `null` | Restrict listing to partition keys that start with this prefix |
+| `start` | `null` | First partition key to list, in lexicographical order |
+| `end` | `null` | Last partition key to list (excluded) |
+| `limit` | `null` | Maximum number of partition keys to list |
+| `reverse` | `false` | Iterate in reverse lexicographical order |
+
+The response consists in a JSON object that repeats the parameters of the query and gives the result (see below).
+
+The listing starts at partition key `start`, or if not specified at the
+smallest partition key that exists.  It returns partition keys in increasing
+order, or decreasing order if `reverse` is set to `true`,
+and stops when either of the following conditions is met:
+
+1. if `end` is specfied, the partition key `end` is reached or surpassed (if it
+   is reached exactly, it is not included in the result)
+
+2. if `limit` is specified, `limit` partition keys have been listed
+
+3. no more partition keys are available to list
+
+In case 2, and if there are more partition keys to list before condition 1
+triggers, then in the result `more` is set to `true` and `nextStart` is set to
+the first partition key that couldn't be listed due to the limit. In the first
+case (if the listing stopped because of the `end` parameter), `more` is not set
+and the `nextStart` key is not specified.
+
+Note that if `reverse` is set to `true`, `start` is the highest key
+(in lexicographical order) for which values are returned.
+This means that if an `end` is specified, it must be smaller than `start`,
+otherwise no values will be returned.
+
+Example query:
+
+```
+GET /my_bucket HTTP/1.1
+```
+
+Example response:
+
+```json
+HTTP/1.1 200 OK
+
+{
+  prefix: null,
+  start: null,
+  end: null,
+  limit: null,
+  reverse: false,
+  partitionKeys: [
+    {
+      pk: "keys",
+      entries: 3043,
+      conflicts: 0,
+      values: 3043,
+      bytes: 121720,
+    },
+    {
+      pk: "mailbox:INBOX",
+      entries: 42,
+      conflicts: 1,
+      values: 43,
+      bytes: 142029,
+    },
+    {
+      pk: "mailbox:Junk",
+      entries: 2991
+      conflicts: 0,
+      values: 2991,
+      bytes: 12019322,
+    },
+    {
+      pk: "mailbox:Trash",
+      entries: 10,
+      conflicts: 0,
+      values: 10,
+      bytes: 32401,
+    },
+    {
+      pk: "mailboxes",
+      entries: 3,
+      conflicts: 0,
+      values: 3,
+      bytes: 3019,
+    },
+  ],
+  more: false,
+  nextStart: null,
+}
+```
+
+
+### Operations on batches of items
+
+**InsertBatch: `POST /<bucket>`**
+
+Simple insertion and deletion of triplets. The body is just a list of items to
+insert in the following format:
+`{ pk: "<partition key>", sk: "<sort key>", ct: "<causality token>"|null, v: "<value>"|null }`.
+
+The causality token should be the one returned in a previous read request (e.g.
+by ReadItem or ReadBatch), to indicate that this write takes into account the
+values that were returned from these reads, and supersedes them causally. If
+the triplet is inserted for the first time, the causality token should be set to
+`null`.
+
+The value is expected to be a base64-encoded binary blob. The value `null` can
+also be used to delete the triplet while preserving causality information: this
+allows to know if a delete has happenned concurrently with an insert, in which
+case both are preserved and returned on reads (see below).
+
+Partition keys and sort keys are utf8 strings which are stored sorted by
+lexicographical ordering of their binary representation.
+
+Example query:
+
+```json
+POST /my_bucket HTTP/1.1
+
+[
+  { pk: "mailbox:INBOX", sk: "001892831", ct: "opaquetoken321", v: "b64cryptoblob321updated" },
+  { pk: "mailbox:INBOX", sk: "001892912", ct: null, v: "b64cryptoblob444" },
+  { pk: "mailbox:INBOX", sk: "001892932", ct: "opaquetoken654", v: null },
+]
+```
+
+Example response:
+
+```
+HTTP/1.1 200 OK
+```
+
+
+**ReadBatch: `POST /<bucket>?search`**, or alternatively<br/>
+**ReadBatch: `SEARCH /<bucket>`**
+
+Batch read of triplets in a bucket.
+
+The request body is a JSON list of searches, that each specify a range of
+items to get (to get single items, set `singleItem` to `true`). A search is a
+JSON struct with the following fields:
+
+| name | default value | meaning |
+| - | - | - |
+| `partitionKey` | **mandatory** | The partition key in which to search |
+| `prefix` | `null` | Restrict items to list to those whose sort keys start with this prefix |
+| `start` | `null` | The sort key of the first item to read |
+| `end` | `null` | The sort key of the last item to read (excluded) |
+| `limit` | `null` | The maximum number of items to return |
+| `reverse` | `false` | Iterate in reverse lexicographical order on sort keys |
+| `singleItem` | `false` | Whether to return only the item with sort key `start` |
+| `conflictsOnly` | `false` | Whether to return only items that have several concurrent values |
+| `tombstones` | `false` | Whether or not to return tombstone lines to indicate the presence of old deleted items |
+
+
+For each of the searches, triplets are listed and returned separately. The
+semantics of `prefix`, `start`, `end`, `limit` and `reverse` are the same as for ReadIndex. The
+additionnal parameter `singleItem` allows to get a single item, whose sort key
+is the one given in `start`. Parameters `conflictsOnly` and `tombstones`
+control additional filters on the items that are returned.
+
+The result is a list of length the number of searches, that consists in for
+each search a JSON object specified similarly to the result of ReadIndex, but
+that lists triplets within a partition key.
+
+The format of returned tuples is as follows: `{ sk: "<sort key>", ct: "<causality
+token>", v: ["<value1>", ...] }`, with the following fields:
+
+- `sk` (sort key): any unicode string used as a sort key
+
+- `ct` (causality token): an opaque token served by the server (generally
+  base64-encoded) to be used in subsequent writes to this key
+
+- `v` (list of values): each value is a binary blob, always base64-encoded;
+  contains multiple items when concurrent values exists
+
+- in case of concurrent update and deletion, a `null` is added to the list of concurrent values
+
+- if the `tombstones` query parameter is set to `true`, tombstones are returned
+  for items that have been deleted (this can be usefull for inserting after an
+  item that has been deleted, so that the insert is not considered
+  concurrent with the delete). Tombstones are returned as tuples in the
+  same format with only `null` values
+
+Example query:
+
+```json
+POST /my_bucket?search HTTP/1.1
+
+[
+  {
+    partitionKey: "mailboxes",
+  },
+  {
+    partitionKey: "mailbox:INBOX",
+    start: "001892831",
+    limit: 3,
+  },
+  {
+    partitionKey: "keys",
+    start: "0",
+    singleItem: true,
+  },
+]
+```
+
+Example associated response body:
+
+```json
+HTTP/1.1 200 OK
+
+[
+  {
+    partitionKey: "mailboxes",
+    prefix: null,

+    ],
+    more: false,
+    nextStart: null,
+  },
+]
+```
+
+
+
+**DeleteBatch: `POST /<bucket>?delete`**
+
+Batch deletion of triplets. The request format is the same for `POST
+/<bucket>?search` to indicate items or range of items, except that here they
+are deleted instead of returned, but only the fields `partitionKey`, `prefix`, `start`,
+`end`, and `singleItem` are supported. Causality information is not given by
+the user: this request will internally list all triplets and write deletion
+markers that supersede all of the versions that have been read.
+
+This request returns for each series of items to be deleted, the number of
+matching items that have been found and deleted.
+
+Example query:
+
+```json
+POST /my_bucket?delete HTTP/1.1
+
+[
+  {
+    partitionKey: "mailbox:OldMailbox",
+  },
+  {
+    partitionKey: "mailbox:INBOX",
+    start: "0018928321",
+    singleItem: true,
+  },
+]
+```
+
+Example response:
+
+```
+HTTP/1.1 200 OK
+
+[
+  {
+    partitionKey: "mailbox:OldMailbox",
+    prefix: null,
+    start: null,
+    end: null,
+    singleItem: false,
+    deletedItems: 35,
+  },
+  {
+    partitionKey: "mailbox:INBOX",
+    prefix: null,
+    start: "0018928321",
+    end: null,
+    singleItem: true,
+    deletedItems: 1,
+  },
+]
+```
+
+
+## Internals: causality tokens
+
+The method used is based on DVVS (dotted version vector sets). See:
+
+- the paper "Scalable and Accurate Causality Tracking for Eventually Consistent Data Stores"
+- <https://github.com/ricardobcl/Dotted-Version-Vectors>
+
+For DVVS to work, write operations (at each node) must take a lock on the data table.
