I recently implemented a backup workflow for me. I heavily use restic for desktop backup and for a full system backup of my local server. It works amazingly good. I always have a versioned backup without a lot of redundant data. It is fast, encrypted and compressed.
But I wondered, how do you guys do your backups? What software do you use? How often do you do them and what workflow do you use for it?
I have a server with a RAID-1 array, that makes daily, weekly, and monthly read only btrfs snapshots. The whole thing (sans snapshots) is sync’d with syncthing to two rPi’s in two different geographic locations.
I know neither raid nor syncthing are “real” backup solutions, but with so many copies of the files living in so many locations (in addition to my phone, laptop, etc.) I’m reasonably confident its a decent solution.
