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.
Im quite new in selfohsting and backups. I went for duplicaty and it is perfect, but heared bad stories and now I use kopia daily backups to another drive and also to B2. Duplicaty is still doing daily backups, but only few important folders to google drive.
Ive heared only good stories about kopia and no one mentioned it
