I've been using Duplicati forever. The fact that it's C# is a bit of a pain (some distros don't have recent Mono), but running it in Docker is easy enough. Being able to check the status of backups and restore files from a web UI is a huge plus, so is the ability to run the same app on all platforms.

I've found duplicity to be a little simplistic and brittle. Purging old backups is also difficult, you basically have to make a full backup (i.e. non-incremental) before you can do that, which increases bandwidth and storage cost.

Restic looks great feature-wise, but still feels like the low-level component you'd use to build a backup system, not a backup system in itself. It's also pre-1.0.

Interesting, I will check Restic out, I’ve heard other good things about it. Duplicity is a bit of a pain to set up and Restic’s single binary model is more straightforward (Go is a miracle). Thanks for the recommendation!

GPG is a bit quirky but I do regularly check my backups and restores (if once every few months counts as regular).

+1 for Restic

It's brilliant, works like a charm on freebsd windows and a rpi with linux since over 2 years.
