-#### SSE-C encryption (since Garage v1.0)
-
-Since version 1.0, Garage supports server-side encryption with customer keys
-(SSE-C).  In this mode, Garage is responsible for encrypting and decrypting
-objects, but it does not store the encryption key itself. The encryption key
-should be provided by Nextcloud upon each request.  This mode of operation is
-supported by Nextcloud and it has successfully been tested together with
-Garage.
-
-To enable SSE-C encryption:
-
-1. Make sure your Garage server is accessible via SSL through a reverse proxy
-   such as Nginx, and that it is using a valid public certificate (Nextcloud
-   might be able to connect to an S3 server that is using a self-signed
-   certificate, but you will lose many hours while trying, so don't).
-   Configure values for `use_ssl` and `port` accordingly in your `config.php`
-   file.
-
-2. Generate an encryption key using the following command:
-
-    ```
-    openssl rand -base64 32
-    ```
-
-    Make sure to keep this key **secret**!
-
-3. Add the encryption key in your `config.php` file as follows:
-
-
-    ```php
-    <?php
-    $CONFIG = array(
-    'objectstore' => [
-        'class' => '\\OC\\Files\\ObjectStore\\S3',
-        'arguments' => [
-            ...
-            'sse_c_key' => 'exampleencryptionkeyLbU+5fKYQcVoqnn+RaIOXgo=',
-            ...
-        ],
-    ],
-    ```
-
-Nextcloud will now make Garage encrypt files at rest in the storage bucket.
-These files will not be readable by an S3 client that has credentials to the
-bucket but doesn't also know the secret encryption key.

-For standard S3 API requests, Garage does not encrypt data at rest by itself.
-For the most generic at rest encryption of data, we recommend setting up your
-storage partitions on encrypted LUKS devices.
+Garage does not handle data encryption at rest by itself, and instead delegates
+to the user to add encryption, either at the storage layer (LUKS, etc) or on
+the client side (or both). There are no current plans to add data encryption

-Garage does support [SSE-C
-encryption](https://docs.aws.amazon.com/AmazonS3/latest/userguide/ServerSideEncryptionCustomerKeys.html),
-an encryption mode of Amazon S3 where data is encrypted at rest using
-encryption keys given by the client.  The encryption keys are passed to the
-server in a header in each request, to encrypt or decrypt data at the moment of
-reading or writing. The server discards the key as soon as it has finished
-using it for the request.  This mode allows the data to be encrypted at rest by
-Garage itself, but it requires support in the client software. It is also not
-adapted to a model where the server is not trusted or assumed to be
-compromised, as the server can easily know the encryption keys.  Note however
-that when using SSE-C encryption, the only Garage node that knows the
-encryption key passed in a given request is the node to which the request is
-directed (which can be a gateway node), so it is easy to have untrusted nodes
-in the cluster as long as S3 API requests containing SSE-C encryption keys are
-not directed to them.
-
-Implementing automatic data encryption directly in Garage without client-side
-management of keys (something like
-[SSE-S3](https://docs.aws.amazon.com/AmazonS3/latest/userguide/UsingServerSideEncryption.html))
-could make things simpler for end users that don't want to setup LUKS, but also
-raises many more questions, especially around key management: for encryption of
-data, where could Garage get the encryption keys from? If we encrypt data but
-keep the keys in a plaintext file next to them, it's useless. We probably don't
-want to have to manage secrets in Garage as it would be very hard to do in a

 ```
 
-This command will simultaneously build all of the required Nix paths (using at

+For example, the Nix project does not provide binaries for cross compiling to i686 and thus we need to compile gcc on our own.
+We do not want to compile gcc each time, so even if it is a compile time dependency, we want to cache it.
+
+This time, the command is a bit more involved:
+
+```bash
+nix copy --to \

+   $(nix-store -qR --include-outputs \

+This is the command we use in our CI as we expect the final binary to change, so we mainly focus on
+caching our development dependencies.
+
+*Currently there is no automatic garbage collection of the cache: we should monitor its growth.
+Hopefully, we can erase it totally without breaking any build, the next build will only be slower.*
+
+In practise, we concluded that we do not want to cache all the compilation dependencies.
+Instead, we want to cache the toolchain we use to build Garage each time we change it.

-## Replacement scenario 3: corrupted metadata {#corrupted_meta}
-
-In some cases, your metadata DB file might become corrupted, for instance if
-your node suffered a power outage and did not shut down properly. In this case,
-you can recover without having to change the node ID and rebuilding a cluster
-layout. This means that data blocks will not need to be shuffled around, you
-must simply find a way to repair the metadata file. The best way is generally
-to discard the corrupted file and recover it from another source.
-
-First of all, start by locating the database file in your metadata directory,
-which [depends on your `db_engine`
-choice](@/documentation/reference-manual/configuration.md#db_engine).  Then,
-your recovery options are as follows:
-
-- **Option 1: resyncing from other nodes.** In case your cluster is replicated
-  with two or three copies, you can simply delete the database file, and Garage
-  will resync from other nodes. To do so, stop Garage, delete the database file
-  or directory, and restart Garage. Then, do a full table repair by calling
-  `garage repair -a --yes tables`.  This will take a bit of time to complete as
-  the new node will need to receive copies of the metadata tables from the
-  network.
-
-- **Option 2: restoring a snapshot taken by Garage.** Since v0.9.4, Garage can
-  [automatically take regular
-  snapshots](@/documentation/reference-manual/configuration.md#metadata_auto_snapshot_interval)
-  of your metadata DB file. This file or directory should be located under
-  `<metadata_dir>/snapshots`, and is named according to the UTC time at which it
-  was taken. Stop Garage, discard the database file/directory and replace it by the
-  snapshot you want to use. For instance, in the case of LMDB:
-
-  ```bash
-  cd $METADATA_DIR
-  mv db.lmdb db.lmdb.bak
-  cp -r snapshots/2024-03-15T12:13:52Z db.lmdb
-  ```
-
-  And for Sqlite:
-
-  ```bash
-  cd $METADATA_DIR
-  mv db.sqlite db.sqlite.bak
-  cp snapshots/2024-03-15T12:13:52Z db.sqlite
-  ```
-
-  Then, restart Garage and run a full table repair by calling `garage repair -a
-  --yes tables`.  This should run relatively fast as only the changes that
-  occurred since the snapshot was taken will need to be resynchronized. Of
-  course, if your cluster is not replicated, you will lose all changes that
-  occurred since the snapshot was taken.
-
-- **Option 3: restoring a filesystem-level snapshot.** If you are using ZFS or
-  BTRFS to snapshot your metadata partition, refer to their specific
-  documentation on rolling back or copying files from an old snapshot.

-Sled was supported until Garage v0.9.x, and was removed in Garage v1.0.
-You can still use an older binary of Garage (e.g. v0.9.4) to migrate
-old Sled metadata databases to another engine.
+Sled was the only database engine up to Garage v0.7.0. Performance issues and

+Since v0.9.0, LMDB is the default engine instead of Sled, and Sled is

 Performance characteristics of the different DB engines are as follows:
 
-- LMDB: the recommended database engine for high-performance distributed clusters.
-LMDB works very well, but is known to have the following limitations:
+- Sled: tends to produce large data files and also has performance issues,
+  especially when the metadata folder is on a traditional HDD and not on SSD.
 
-  - The data format of LMDB is not portable between architectures, so for
-    instance the Garage database of an x86-64 node cannot be moved to an ARM64
-    node.
-
-  - While LMDB can technically be used on 32-bit systems, this will limit your
-    node to very small database sizes due to how LMDB works; it is therefore
-    not recommended.
-
-  - Several users have reported corrupted LMDB database files after an unclean
-    shutdown (e.g. a power outage). This situation can generally be recovered
-    from if your cluster is geo-replicated (by rebuilding your metadata db from
-    other nodes), or if you have saved regular snapshots at the filesystem
-    level.
-
-  - Keys in LMDB are limited to 511 bytes. This limit translates to limits on
-    object keys in S3 and sort keys in K2V that are limted to 479 bytes.

-
-**This guide explains how to migrate to 1.0 if you have an existing 0.9 cluster.
-We don't recommend trying to migrate to 1.0 directly from 0.8 or older.**
-
-This migration procedure has been tested on several clusters without issues.
-However, it is still a *critical procedure* that might cause issues.
-**Make sure to back up all your data before attempting it!**
-
-You might also want to read our [general documentation on upgrading Garage](@/documentation/operations/upgrading.md).
-
-## Changes introduced in v1.0
-
-The following are **breaking changes** in Garage v1.0 that require your attention when migrating:
-
-- The Sled metadata db engine has been **removed**. If your cluster was still
-  using Sled, you will need to **use a Garage v0.9.x binary** to convert the
-  database using the `garage convert-db` subcommand. See
-  [here](@/documentation/reference-manual/configuration.md#db_engine) for the
-  details of the procedure.
-
-The following syntax changes have been made to the configuration file:
-
-- The `replication_mode` parameter has been split into two parameters:
-  [`replication_factor`](@/documentation/reference-manual/configuration.md#replication_factor)
-  and
-  [`consistency_mode`](@/documentation/reference-manual/configuration.md#consistency_mode).
-  The old syntax using `replication_mode` is still supported for legacy
-  reasons and can still be used.
-
-- The parameters `sled_cache_capacity` and `sled_flush_every_ms` have been removed.
-
-## Migration procedure
-
-The migration to Garage v1.0 can be done with almost no downtime,
-by restarting all nodes at once in the new version.
-
-The migration steps are as follows:
-
-1. Do a `garage repair --all-nodes --yes tables`, check the logs and check that
-   all data seems to be synced correctly between nodes. If you have time, do
-   additional `garage repair` procedures (`blocks`, `versions`, `block_refs`,
-   etc.)
-
-2. Ensure you have a snapshot of your Garage installation that you can restore
-   to in case the upgrade goes wrong:
-
-   - If you are running Garage v0.9.4 or later, use the `garage meta snapshot
-     --all` to make a backup snapshot of the metadata directories of your nodes
-     for backup purposes, and save a copy of the following files in the
-     metadata directories of your nodes: `cluster_layout`, `data_layout`,
-     `node_key`, `node_key.pub`.
-
-   - If you are running a filesystem such as ZFS or BTRFS that support
-     snapshotting, you can create a filesystem-level snapshot to be used as a
-     restoration point if needed.
-
-   - In other cases, make a backup using the old procedure: turn off each node
-     individually; back up its metadata folder (for instance, use the following
-     command if your metadata directory is `/var/lib/garage/meta`: `cd
-     /var/lib/garage ; tar -acf meta-v0.9.tar.zst meta/`); turn it back on
-     again.  This will allow you to take a backup of all nodes without
-     impacting global cluster availability.  You can do all nodes of a single
-     zone at once as this does not impact the availability of Garage.
-
-3. Prepare your updated binaries and configuration files for Garage v1.0
-
-4. Shut down all v0.9 nodes simultaneously, and restart them all simultaneously
-   in v1.0.  Use your favorite deployment tool (Ansible, Kubernetes, Nomad) to
-   achieve this as fast as possible.  Garage v1.0 should be in a working state
-   as soon as enough nodes have started.
-
-5. Monitor your cluster in the following hours to see if it works well under
-   your production load.

+
+Garage est un système de stockage de données léger, géo-distribué, qui
+implémente le protocole de stockage S3 de Amazon. Garage est destiné
+principalement à l'auto-hébergement sur du matériel courant d'occasion. À ce
+titre, il doit tolérer un grand nombre de pannes: coupures de courant, coupures
+de connexion Internet, pannes de machines, ... Il doit également être facile à
+déployer et à maintenir, afin de pouvoir être facilement utilisé par des
+amateurs ou des petites organisations.
+
+Cette présentation vous proposera un aperçu de Garage et du choix technique
+principal qui rend un système comme Garage possible: le refus d'utiliser des
+algorithmes de consensus, remplacés avantageusement par des méthodes à
+cohérence faible.  Notre modèle est fortement inspiré de la base de donnée
+Dynamo (DeCandia et al, 2007), et fait usage des types de données CRDT (Shapiro
+et al, 2011).  Nous exploreront comment ces méthodes s'appliquent à la
+construction de l'abstraction "stockage objet" dans un système distribué, et
+quelles autres abstractions peuvent ou ne peuvent pas être construites dans ce
+modèle.

+
+Garage is a lightweight geo-distributed data store that implements the Amazon
+S3 object storage protocol.  Garage is meant primarily for self-hosting at home
+on second-hand commodity hardware, meaning it has to tolerate a wide variety of
+failure scenarios such as power cuts, Internet disconnections and machine
+crashes. It also has to be easy to deploy and maintain, so that hobbyists and
+small organizations can use it without trouble. 
+
+This talk will present Garage and the key technical choice that made Garage
+possible: refusing to use consensus algorithms and using instead weak
+consistency methods, with a model that is loosely based on that of the Dynamo
+database (DeCandia et al, 2007) and that makes heavy use of conflict-free
+replicated data types (Shapiro et al, 2011).  We will explore how these methods
+are suited to building the "object store" abstraction in a distributed system,
+and what other abstractions are possible or impossible to build in this model.

-	\frametitle{Deployment advice for very large clusters}
-	\begin{itemize}
-		\item Metadata storage:
-			\begin{itemize}
-				\item ZFS mirror (x2) on fast NVMe
-				\item Use LMDB storage engine
-			\end{itemize}
-			\vspace{.5em}
-		\item Data block storage:
-			\begin{itemize}
-				\item Use Garage's native multi-HDD support
-				\item XFS on individual drives
-				\item Increase block size (1MB $\to$ 10MB, requires more RAM and good networking)
-				\item Tune \texttt{resync-tranquility} and \texttt{resync-worker-count} dynamically
-			\end{itemize}
-			\vspace{.5em}
-		\item Other :
-			\begin{itemize}
-				\item Split data over several buckets
-				\item Use less than 100 storage nodes
-				\item Use gateway nodes
-			\end{itemize}
-			\vspace{.5em}
-	\end{itemize}
-	Our deployments: $< 10$ TB. Some people have done more!
