Delete Non-CSM snapshots from AWS

To remove snapshots that are not taken by Cloud Snapshot Manager (referred to as Non-CSM snapshots) from your AWS cloud account, first filter the Non-CSM snapshots based on date, volume size, range, and so on in the Snapshots page of Cloud Snapshot Manager. Then select one or more snapshots, and click Expire Now. You can delete up to 1000 snapshots at a time.
