You can unmount (or delete) clones.
From the Snap Creator GUI main menu, select Management > Configurations.
From the Configurations tab, select a configuration file, and then select Actions > Unmount.
From the Additional parameters window, select the controller, volume, Snapshot copy policy containing the mounted backup, and specific Snapshot copy name on which the clone was created; then click OK.
The clone is unmounted; the Snapshot copy is not deleted.
