Deleting an Automated Snapshot

Only DWS can delete automated snapshots; you cannot delete them manually.

DWS deletes an automated snapshot if:

The retention period of the snapshot ends.
The cluster is deleted.

To help users restore a cluster deleted by mistake, DWS provides the following policies (supported only in clusters of version 8.2.0 and later):

If the latest snapshot is an automated snapshot, it will be retained for one day.
If the latest snapshot is a manual snapshot, the automated snapshot of the cluster will be deleted.
