Hey there,
I’m in need of a bit of wisdom here:
I recently got myself a shiny new Vserver and have it running exclusively with docker containers that use regular volumes.
Now: how would I back this thing up? I mean, I have read a lot about borg for example, but I’m not sure how to do it the right way:
Do I just copy / to a repo and fiddle the data back in place if stuff goes wrong, or would it be wiser to backup the volumes, do a docker save and export the images to a folder and then send that to the storage box?
Since docker should stop the containers to prevent data inconsistency during a backup: How do I tell Borg to do that? I’ve seen several approaches (Borg Dockerized with some sort of access to docker’s .sock, Borg setup on the host, and some even wilder approaches).
Since Backups aren’t something you can “try again” once you need them, I’d rather have a solution that works.
For everyone here: I decided on restic and wrote a little script that backs up basically all docker volumes after stopping all containers. Now I just gotta collect and save all relevant docker compose scripts somewhere (and incorporate all the little changes I made to the containers after deployment)

Restic is awesome and has been rock solid for me for a few years now. Good choice.
