I don't think Attic is a good choice anymore; it's unmaintained for ~2 years and has critical data integrity and security bugs. Borg is the active fork. The Borg team is developing new features while also triaging the Attic bug tracker, although they've worked through most of those Attic bugs by now: https://github.com/borgbackup/borg/issues/5 I like Borg overall. I've restored from it many times now, and it's always worked. The developers are actively maintaining and improving the software, and there is even a commercial offering (rsync.net). It's a very similar backup paradigm to Tarsnap (snapshots composed of deduplicated encrypted chunks), although the key management is less advanced. I'm not familiar with Duplicity so I can't compare it to Borg.
