Author here. We'd love this to be a thing, but this is young software, so we don't recommend relying on this as a single way of doing a backup for now. Bear in mind that our main use case is for things that you can reproduce in principle (builds of a commit history, see manyclangs).

I appreciate your response, and thanks very much for the clarification of use case; very helpful! Thanks also of course for building this!

For backup you probably want something like Borg to handle deduplication of identical content between backups.

Author here, I agree with xdfgh1112, please take care before using brand new software to store your backups!

Yes, any time that i use something new or different (or both) for something as essential as backups, i take great and deliberate care...and test, test, test...well before standardizing on it. ;-)
