To change the active DPM for a snapshot or VDG snapshot:

Renaming snapshots or VDG snapshots
To rename a snapshot or VDG snapshot:
1. Right-click the snapshot or VDG snapshot that you want to rename.
2. Select Manage > Rename. The Rename wizard opens to the New name screen.
3. In the New name field, enter a new name for the snapshot or VDG snapshot.
4. Click Next. A confirmation screen appears.
5. Click Finish. The snapshot or VDG snapshot is renamed.
Deleting snapshots or VDG snapshots
The snapshot service enables you to delete a snapshot or VDG snapshot if it is not being used by
another snapshot service component (for example, a PiT created on this snapshot or VDG snapshot).
CAUTION:
• When a snapshot or VDG snapshot is deleted, the hosts that use it lose access to the snapshot or
VDG snapshot. It is therefore recommended that you unmount the snapshot or VDG snapshot on
the host prior to deleting it on VSM. When a snapshot or VDG snapshot is deleted, all the data
modifications that the snapshot or VDG snapshot maintained are lost. The temporary virtual disks
allocated to store this data are deleted, and the capacity returns to the storage pools from which
they were allocated.
• When deleting a VSS snapshot from within VSM, you are prompted with a confirmation message
indicating that the snapshot was created by VSS. Confirming the deletion deletes both the VSS
snapshot and its VSS PiTs. For more information about VSS snapshots, see
“Working with VSS snapshots and PiTs” on page 225.
To delete a snapshot or VDG snapshot:
1. Right-click the snapshot.
2. Select Delete. A confirmation message appears.
3. Click Finish. The snapshot’s status changes to delete. When the deletion is complete, the snapshot
disappears from the snapshots list.
Working with VSS snapshots and PiTs
VSM is compatible with Microsoft’s Volume Shadow Copy Service (VSS) and enables you to view
VSS objects within VSM. You cannot create VSS objects using VSM.
