Honestly, I sort of looked at it for conventional backup strategy...as in, i wonder if it could work as a replacement for tar-zipping up a directory, etc. But, not sure if the use cases is appropriate.
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).
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. ;-)
