Prerequisites for application-managed snapshots
Creating an application-managed snapshot using the LeftHand OS software is the same as creating
any other snapshot. However, you must select the Application-Managed Snapshot option in the
New Snapshot window. You can create application-managed snapshots for both single and
scheduled snapshots. See the HP StoreVirtual Storage Application Aware Snapshot Manager
Deployment Guide for server-side requirements for installing and configuring the Application Aware
Snapshot Manager.
The following are required for application-managed snapshots:

Application-managed snapshots for volume sets
When you create an application-managed snapshot of a volume in a volume set, the software
recognizes that the volume is part of a volume set, and prompts you to create a snapshot for each
volume in the volume set. The result is a snapshot set that corresponds to the volume set. To see
any associated snapshots, select a snapshot, click the Details tab, and look at the Snapshot Set
field.
NOTE: After you create snapshots for a volume set, typically you do not want to delete individual
snapshots from the snapshot set. You want to keep or delete all snapshots for the volume set. If
you need to roll back to a snapshot, typically you want to roll back each volume in the volume set
to its corresponding snapshot. The system gives you the option to automatically delete or roll back
all associated volumes.
