Hi all
I’m running several docker containers with local persistent volumes that I would like to backup. I haven’t found an easy method to do so.
What do you use / recommend to do that? AFAIK you can’t just rsync the volume directory while the container is running.
Besides using bind mounts(As @outcide@kbin.social) mentions, you can run a backup container, that mounts the volume, that you would like to create a backup for. The backup container would handle backing up the volume at regular interval.
This is what I do in thedocker-compose and k3s containers I backup. I can recommend autorestic as the container for backup, but there is a lot of options.
