> Current when a new savepoint is created based on a source savepoint, then there are references in the new savepoint to the source savepoint. Here is the [State Processing API doc|https://ci.apache.org/projects/flink/flink-docs-release-1.9/dev/libs/state_processor_api.html] says: 
> bq. Note: When basing a new savepoint on existing state, the state processor api makes a shallow copy of the pointers to the existing operators. This means that both savepoints share state and one cannot be deleted without corrupting the other!
> This JIRA is to request an option to have a deep copy (instead of shallow copy) such that the new savepoint is self-contained.
