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.

    Use bind mounts instead of docker volumes. Then you just have normal directories to back up, the same as you would anything else.

    In general, it’s not a problem to back up files while the container is running. The exception to this is databases. To have reliable database backups, you need to stop the container (or quiesce/pause the database if it supports it) before backing up the raw database files (including SQLite).

      This is your answer. It also has the benefit of allowing you to have a nice folder structure for your Docker setup, where you have a folder for each service holding the corresponding compose yaml and data folder(s)
