docker-duplicity-backup

Docker container and script to backup a list of docker volumes to a remote duplicity target.

Usage

$ ./docker-duplicity-backup <config_file>

The config_file parameter is mandatory and must designate a script file which set these variables:

  • DOCKER_HOSTNAME: hostname used for the container running the backup (optional; defaults to 'backup'). This hostname should be the same through incremental backups, or duplicity will complain.
  • VOLUMES: space separated list of docker volumes to backup (mandatory).
  • DUPLICITY_REMOTE_URI: target URI for duplicity backup (mandatory; e.g. 'rsync://backup.example.com//target/path').
  • DUPLICITY_CACHE_VOLUME: docker volume name to use for duplicity cache persistency (optional; defaults to 'backup_cache').
  • INIT_FOLDER: local path to mount into the container as /root/init.d (optional). The scripts into this folder will be sourced by the container's entrypoint before starting the backup. Useful for starting an stunnel service.
  • DOCKER_EXTRA_OPTIONS: docker run options such as environment variables or extra volumes (optional). Useful for importing an ssh configuration folder.
