Automatically prune old backups
When BACKUP_RETENTION_DAYS is configured, the command will check if there are any archives in the remote storage backend(s) or local archive that are older than the given retention value and rotate these backups away.
{: .note }
Be aware that this mechanism looks at all files in the target bucket or archive, which means that other files that are older than the given deadline are deleted as well.
In case you need to use a target that cannot be used exclusively for your backups, you can configure BACKUP_PRUNING_PREFIX to limit which files are considered eligible for deletion:
version: '3'
services:
# ... define other services using the `data` volume here
backup:
image: offen/docker-volume-backup:v2
environment:
BACKUP_FILENAME: backup-%Y-%m-%dT%H-%M-%S.tar.gz
BACKUP_PRUNING_PREFIX: backup-
BACKUP_RETENTION_DAYS: '7'
volumes:
- ${HOME}/backups:/archive
- data:/backup/my-app-backup:ro
- /var/run/docker.sock:/var/run/docker.sock:ro
