Docker resetting and losing backup info

[BrandonMillerSwingtech]

I am running Backrest in Docker on my Unraid server. I have got it working pretty well, except for one thing. Any time I go into the Docker settings and change a path or variable, Unraid re-downloads and resets the container. I have the BACKREST_CONFIG environmental variable pointing to my persistent config path so that when it resets I no longer lose the configuration of the repos and plans. However, if it resets, any previous snapshots do not show up under the repo. If I run stats it picks it up and shows it in the operation list, but it shows it as an unassociated backup. Is there a setting I'm missing to make sure the snapshots show up and are still associated like usual if the docker gets reset? Thank you.

Hey, sounds like your environment variables (or mounts) are not setup correctly. Some portion of backrest's data is getting lost when the container restarts.

Make sure your config matches

services:
  backrest:
    image: garethgeorge/backrest
    container_name: backrest
    hostname: backrest #Use this to set the hostname instead of container ID to the config.json and WebUI.
    volumes:
      - ./backrest/data:/data
      - ./backrest/config:/config
      - ./backrest/cache:/cache
      - /MY-BACKUP-DATA:/userdata # mount your directories to backup somewhere in the filesystem
      - /MY-REPOS:/repos # (optional) mount your restic repositories somewhere in the filesystem.
    environment:
      - BACKREST_DATA=/data # path for backrest data. restic binary and the database are placed here.
      - BACKREST_CONFIG=/config/config.json # path for the backrest config file.
      - XDG_CACHE_HOME=/cache # path for the restic cache which greatly improves performance.

And in particular it sounds like the BACKREST_DATA directory is being lost. I recommend using the default value /data/ for the environment variable and making sure that you map your path on the host to /data in the container.
