What's your backup strategy? (feddit.nl)

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.

321 strategy: 3 copies of everything important, 2 on-site, 1 in cloud. I have a TrueNAS Scale NAS running RAID5 on ZFS. All the laptops, desktops, etc. backup to the NAS. (Mostly Macs, so we use time machine over the network). So the original laptop/desktop is 1 copy. The NAS is a second copy on-site, and then TrueNAS has lots of cloud options. I use Amazon S3 myself, but there are lots of choices.

Prior to this I had a Synology NAS. It was "small" (6TB), so it has a RAID mirror of 6TB drives and a single 6TB external USB that had a backup of the mirrored pair (second copy on-site). Then I also used Synology's software to backup to S3.

For my Internet-facing VMs, they all run in xcp-ng and I use Xen Orchestra to manage them. I run regular snapshots nightly, and then use NFS to copy them to a cloud server. That's sloppy, and sometimes doesn't work. So the in-the-house stuff is backed up well. The VMs are mostly relying on Xen snapshots and RAID 5.
