For my "most important" data, in your example, I would want to leave it to 26. But I can see that a "simple" rollback logic would probably leave it to 1, and that it is in fact use-case specific. And if the "correct" behavior is use-case specific, then I won't find it in any DB/Storage implementation. In other words, the answer would be: "No, there isn't one. You have to do it yourself."

comment What is the correct term to describe a “persistent transaction”?
While copy-on-write isn't exactly the term I was looking for, it is the technique that would be used implement such a function. And best of all, it can be done at the filesystem level, so it works for most DB. Great answer! Thanks!
