I am trying to setup a restic job to backup my docker stacks, and with half of everything owned by root it becomes problematic. I’ve been wanting to look at podman so everything isn’t owned by root, but for now I want to backup my work I built.

Also, how do you deal with some docker containers having databases. Do you have to create exports for all docker containers that have some form of database?

I’ve spent the last few days moving all my docker containers to a dedicated machine. I was using a mix of NFS and local storage before, but now I am doing everything on local NVME. My original plan was having everything on NFS so I would worry about backups there, and I might go back to that.

    I do this at the file system level, not the file level, using zfs.

    Unless the container has a database, I use zfs snapshots. If it has a database, my script dumps the database first and then does a ZFS snapshot. Then that snapshot is sent via sanoid to a zfs disk that is in a different backup pool.

    This is a block level backup, so it only backs up the actual data blocks that changed.
