I practiced a question similar to this, and I feel like using PITR is the most straightforward way to get back to a specific time.

I think creating a clone from a read replica could work, but I can't recall if it has to be in the same region or if it can be in a different zone.

I remember something about point-in-time recovery being really useful for restoring databases, but I'm not sure if it's the best option here.
