I see many posts asking about what other lemmings are hosting, but I’m curious about your backups.
I’m using duplicity myself, but I’m considering switching to borgbackup when 2.0 is stable. I’ve had some problems with duplicity. Mainly the initial sync took incredibly long and once a few directories got corrupted (could not get decrypted by gpg anymore).
I run a daily incremental backup and send the encrypted diffs to a cloud storage box. I also use SyncThing to share some files between my phone and other devices, so those get picked up by duplicity on those devices.
All of my servers have shell scripts that rsync important stuff to a subdirectory. Other scripts run database dumps a couple of times a day.
My primary server at home then rsyncs my servers’ backup subdirectories to its own, broken out by FQDN.
Leandra then uses Restic to back everything up (herself as well as the other servers’ backups) to Backblaze B2 on a two year cycle.
