I've been using Duplicacy and like it. Everything backs up to my server via Seafile (files) and Immich (photos). Then Duplicacy has a couple of B2 buckets it backs everything up to. Seems to work pretty well so far.
I've tried numerous terminal based backups like restic and Borg, but my newb brain still needs a GUI I guess. I've seen various UIs for those last 2 but haven't tried them yet.
