At first glance, this looks like way too much to trust in the long run. I use git-annex since roughly 10 years to archive files I don't want to loose again. Does everything I want, and is pretty simple for what it gives me. A checksum for every file, replication on a file-basis, does not dictate the underlying filesystem I use. Full syncs are rather slow, but in reality, it doesn't really matter if I have to wait 3 hours or 2 days, just let it run in the background and do its thing.
