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 realized at one point that the amount of data that is truly irreplaceable to me amounts to only - 500GB. So for this important data I back up to my NAS, then from there backup to Backblaze. I also create M-Discs. Two sets, one for home and one I keep at a fiends’ place. Then because “why not” and I already had them sitting around I also backup to two sd cards and keep them on site and off site.
I also backup my other data like tv/movies/music/etc but the sheer volume of data gives me one option, that being a couple usb hard drives I back up to from my NAS.
It's still a WIP but that's pretty much where I'm at as well, was going crazy trying to figure out which multi terabyte service I was going to use when in reality the actually irreplaceable stuff falls well under a single TB of data lol. Might go with Backblaze as well.
