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.
For my server I use duplicity, with a daily incremental backup and sending the encrypted diffs away. I researched a few more options some time ago but nothing really fit my use case, but I'm also not super happy with duplicity. Thanks for suggesting borgbackup.
For my personal data I have a NextCloud on a RPi4 at my parents' place, which also syncs between my laptop that I've left there. For an offline and off-site storage, I use the good old strategy where I bring over an external hard drive, rsync it, and bring it back.
I feel the exact same. I've been using Duplicacy for a couple years, it works, but don't totally love it.
When I researched Borg, Restic, others, there were issues holding me back for each. Many are CLI-driven, which I don't mind for most tools. But when shit hits the fan and I need to restore, I really want to have a UI to make it simple (and easily browse file directories).
