I’m in the process of setting up backups for my home server, and I feel like I’m swimming upstream. It makes me think I’m just taking the wrong approach.
I’m on a shoestring budget at the moment, so I won’t really be able to implement a 3-2-1 strategy just yet. I figure the most bang for my buck right now is to set up off-site backups to a cloud provider. I first decided to do a full-system backup in the hopes I could just restore it and immediately be up and running again. I’ve seen a lot of comments saying this is the wrong approach, although I haven’t seen anyone outline exactly why.
I then decided I would instead cherry-pick my backup locations instead. Then I started reading about backing up databases, and it seems you can’t just back up the data directory (or file in the case of SQLite) and call it good. You need to dump them first and backup the dumps.
So, now I’m configuring a docker-db-backup container to back each one of them up, finding database containers and SQLite databases and configuring a backup job for each one. Then, I hope to drop all of those dumps into a single location and back that up to the cloud. This means that, if I need to rebuild, I’ll have to restore the containers’ volumes, restore the backups, bring up new containers, and then restore each container’s backup into the new database. It’s pretty far from my initial hope of being able to restore all the files and start using the newly restored system.
Am I going down the wrong path here, or is this just the best way to do it?
I looked at Borgbase, but I think it will be a bit more pricey than Restic + Backblaze B2. Looks like Borgbase is $80/year for 1TB, which would be $72/year on B2 and less if I don’t use all of 1TB.
I get this, but it would be faster to restore, right? And the storage I’m going to use to store these files is relatively little compared to the overall volume of data I’m backing up. For example, I’m backing up 100GB of personal photos and home movies. Backing up the system, even though strictly not necessary, will be something like 5% of this, I think, and I’d lean toward paying another few cents every month for a faster restore.
Thanks for your thoughts on the database backups. It’s a helpful perspective!
