OK thanks, I glossed over that part. But really what I look for is (1) explicit claims about durability, and (2) a third party (e.g. Aphyr) actually tested the claims. If there's no claim, then it's impossible to test :) In particular, there are no numbers in the description you quoted. Litestream gives a relatively weak claim, but it could be tested, which actually gives me more confidence in it. If you look at what aphyr writes, a lot of it is claims from vendors that turned out to be false - https://aphyr.com/tags/jepsen https://aphyr.com/tags/jepsen
