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 use syncthing to sync files between phone, pc and server.
The server runs proxmox, with a proxmox backup server in VM. A raspberry pi pulls the backups to an usb ssd, and also rclone them to backblaze.
Syncthing is nice. I don’t backup my pc, as it is done by the server. Reinstalling the pc requires almost no preparation, just set up syncthing again
