Container to use for automating docker-volume backups.

1. docker-volumes mounted as readonly in /volumes/
2. Backup directory mounted in /backup Now it will automatically backup docker volumes to the backup-directory daily @4:00am by default. You can change configuration options via environment variables shown below.

Optional configuration changes via environment variables:

TZ=Europe/London # default: UTC

CRON_BACKUP_PERIOD=0 4 * * * # by default every day @4:00 am. Check https://crontab.guru if you want to change this value.

BACKUP_LOG_RETENTION=30 # (number of logfiles, default 30)

BACKUP_DRYRUN=false # will run rsync in dryrun mode (no actual syncing). Use this for testing if everything is set up correctly. (default false)

Docker run

Without persistent log files (deleted when container is stopped)

docker run -it --rm --name volume-backup -v <your-volume-name-1>:/volumes/<your-volume-name-1>:ro <your-volume-name-x>:/volumes/<your-volume-name-x>:ro -v </your-backup-directory-bind-mount>:/backup -d iluvatyr/volume-backup:1.1

Optionally with persistent logfiles, mounted in /logs, where up to (default) 30 logfiles of each rsync backup are stored

With persistent log files mounted in docker-volume

docker run -it --rm --name volume-backup -v <your-volume-name-1>:/volumes/<your-volume-name-1>:ro <your-volume-name-x>:/volumes/<your-volume-name-x>:ro -v </your-backup-directory-bind-mount>:/backup -v <logs-volume or /bind mount>:/var/log/volume-backup -d iluvatyr/volume-backup:1.1
