Kien, I think what you are asking is: Do incremental checkpoints refer to chunks of state in a previous savepoint. Meaning that if the savepoint is deleted, will the checkpoint be missing some chunks.
The answer is: No, savepoints are always full snapshots and incremental checkpoints do not reference and savepoint state chunks.
