# DEPENDENCIES: btrfs-progs curl rclone jq # DESCRIPTION:
# Script to backup all buckets on a Garage cluster using rclone.
#
# REQUIREMENTS:
# An access key for the backup script must be created in Garage beforehand.
# This script will use the Garage administration API to grant read access
# to this key on all buckets.
#
# A rclone configuration file is expected to be located at `/etc/secrets/rclone.conf`,
# which contains credentials to the following two remotes:
# garage: the Garage server, for read access (using the backup access key)
# backup: the backup location
#
# DEPENDENCIES: (see Dockerfile)
# curl
# jq
# rclone
#
# PARAMETERS (environmenet variables) # PARAMETERS (environmenet variables)
# $BACKUP_BASEDIR => where to store backups and btrfs snapshots # $GARAGE_ADMIN_API_URL => Garage administration API URL (e.g. http://localhost:3903)
# $GARAGE_ADMIN_TOKEN => Garage administration access token # $GARAGE_ADMIN_TOKEN => Garage administration access token
# $GARAGE_ACCESS_KEY => Garage access key # $GARAGE_ACCESS_KEY => Garage access key ID
# $GARAGE_SECRET_KEY => Garage secret key # $TARGET_BACKUP_DIR => Folder on the backup remote where to store buckets
