That sounded like the original question to me. It's an estranged statement to believe otherwise.
So, yes, they save snapshots and take you back to the time of your choosing based off that.
- icebraining 8y agoAn estranged statement? What does that mean? How do you know they use the snapshots method, rather than reversing the changes?
- walru 8y agoOnly just twenty years of software development (and what makes sense). Seeing as the rest of this thread is full of conjecture (and children), I thought I'd influence some experience.

- icebraining 8y agoWell, as Bucephalus355 pointed out in another comment, Oracle has a similar feature and it's not implemented using snapshots.
- matthewmacleod 8y agoSo, yes, they save snapshots and take you back to the time of your choosing based off that. Okay, but you're most likely wrong with that. If you read about how Aurora works (https://www.allthingsdistributed.com/files/p1041-verbitski.pdf https://www.allthingsdistributed.com/files/p1041-verbitski.p...) it seems likely that they will be using log entries to rollback database state, rather than retaining "snapshots".
