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.
I’m paying Google for their enterprise gSuite which is still “unlimited”, and using rclone’s encrypted drive target to back up everything. Have a couple of scripts that make tarballs of each service’s files, and do a full backup daily.
It’s probably excessive, but nobody was ever mad about the fact they had too many backups if they needed them, so whatever.
