I keep my container volumes in sub-directory of that of the docker compose file and tar them up and put them somewhere safe. I spent ages trying to figure out how to back up a container, because I thought that the state of a database was in memory, which I suppose it is, but when you stop it, it’s just a bunch of files like everything else, so I elected to keep it simple. I’ve been thinking of creating a cron job to do it routinely. I’m not sure what you mean regarding the codeberg question.
