Who among us uses snap-sync?

hi, I’m currently testing snapsync, which consists in making incremental backups of btrfs subvolumes on an external medium, while making them visible and usable in snapper (or even btrfs assistant).

The problem is that this software is buggy and no longer seems to be maintained. In particular, I can’t launch a second backup without it crashing, or even delete old backups…

Has anyone managed to get it to work? If not, I’d have to use btrbk and that would multiply the number of interfaces for managing snapshots (snapper, btrfs assistant, command line). In short, not very practical.

thanks for your feedback.
