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 usually just use Restic (not just for servers), for big databases i pipe pg_dump directly into it, and for even bigger ones, i recently moved to pgBackRest.
I ping to a selfhosted Healthchecks instance to see if my backups still run. (or the other way around)
On my main desktop (which recently became a mac, i am sorry) – i currently use Autorestic for multiple locations… its nice to have that yaml, but – well – i am used to bashscripts anyway so it is not that big of a benefit i guess… .
