Every thing is recorded. edit: And I'm being down voted because? Because HN does not enjoy the truth?

  The downvotes are probably because the answer wasn't helpful and doesn't mesh with Amazon's statements.

    How did that work for everyone deleting their FB account?

      How is this conversation helpful to this thread? The question is not "how much does Amazon keep" but "how long/much/granular can I restore".

        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.

          An estranged statement? What does that mean? How do you know they use the snapshots method, rather than reversing the changes?
          • walru 8y ago
            Only 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.

              Well, as Bucephalus355 pointed out in another comment, Oracle has a similar feature and it's not implemented using snapshots.

          So, 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".
