Are files in savepoint still needed after restoring if turning on incremental checkpointing

Hi, Flink Users

Assuming one flink job turns incremental checkpointing and restores from a savepoint. It runs fine for a while and commits one checkpoint and then it fully restarts because of one error. At this time, is it possible that the job still needs files in the original savepoint for recovery? If so, how to determine whether a savepoint is safe to delete?
