alt Hacker NewsNah, you can snapshot every 15 minutes. The snapshot interval depends on the frequency of changes and their capacity, but it's up to them how to allocate these capacities... but it's definitely doable and there are real reasons for doing so. You can collapse deltas between snapshots after some time to make them last longer. I'd be surprised if they don't do that.
As an aside, snapshotting would have prevented a good deal of horror stories shared by people who give AI access to the FS. Well, as long as you don't give it root.......

Nowadays I refuse to do any serious work that isn't in source control anywhere besides my NAS that takes copy-on-write snapshots every 15 minutes. It has saved my butt more times than I can count.
The problem isn't the granularity of the backup but since the worm silently nukes pages, it's virtually impossible to reconcile the state before the attack and the current state, so you have to just forfeit any changes made since then and ask the contributors to do the leg work of reapplying the correct changes
>Nah, you can snapshot every 15 minutes.
obviously you can. but, what is the actual snapshot frequency? like, what is the timestamp of the last known good snapshot? that is what matters.
in any case, the comment you are replying to is a hypothetical, which correctly points out that even a day or two of lost edits is fine (not ideal, but fine). your reply doesnt engage with their comment at all.
