I’ve searched this long and hard and I haven’t really seen a good consensus that made sense. The SEO is really slowing me on this one, stuff like “restic backup database” gets me garbage.
I’ve got databases in docker containers in LXC containers, but that shouldn’t matter (I think).
me-me about containers in containers
I’ve seen:
- Just backup the databases like everything else, they’re “transactional” so it’s cool
- Some extra docker image to load in with everything else that shuts down the databases in docker so they can be backed up
- Shut down all database containers while the backup happens
- A long ass backup script that shuts down containers, backs them up, and then moves to the next in the script
- Some mythical mentions of “database should have a command to do a live snapshot, git gud”
None seem turnkey except for the first, but since so many other options exist I have a feeling the first option isn’t something you can rest easy with.
I’d like to minimize backup down times obviously, like what if the backup for whatever reason takes a long time? I’d denial of service myself trying to backup my service.
I’d also like to avoid a “long ass backup script” cause autorestic/borgmatic seem so nice to use. I could, but I’d be sad.
So, what do y’all do to backup docker databases with backup programs like Borg/Restic?
I have also been wanting to try borg for at least offsite backups. Currently been using a “long ass backup script” with how little time I currently have.
I’ve replaced my “long ass script” I was using for rsync with a much shorter one that uses borg. 10/10 would recommend.
Not sure how much time it will save because in both cases the stuff that took the most time was figuring out each tool’s voodoo for including/excluding directories from backup.
I’m coming from rsync too, hoping for the same good stuff
