Are cross region RDS snapshot copies incremental?

For a scenario where the customer is transferring RDS snapshot copies from one region to another region on periodic basis. After the first snapshot copy (which I assume is always a full copy), are the subsequent copies incremental or full copy?

What if the customer deletes the first snapshot copy in the target region and then initiates a copy from the latest snapshot available in source region? Would this be a full copy?

As is the case with the other copy operations, the copy is done on an incremental basis, and only the data that has changed since the last snapshot of a given Database Instance will be copied. When you delete a snapshot, deletion is limited to the data that will not affect other snapshots.

For second part - Yes, The RDS system will ensure that the last snapshot has all the available data and the previous snapshots are not required
