Timing For A Scheduled Remote Snapshot - HP StorageWorks P4000 User Manual

6. Select a retention interval for the primary snapshot, either number of days or number of snapshots.
You can retain up to 50 snapshots for a volume.
7. If you want to use VSS to quiesce the application before creating the snapshot, select the
Application-Managed Snapshot check box.
This option requires the use of the VSS Provider. For more information, see "Requirements for
application-managed snapshots" in the HP StorageWorks P4000 SAN Solution user guide. If
the VSS Provider is not installed, SAN/iQ allows creation of a point-in-time snapshot (not using
VSS).
This option quiesces VSS-aware applications on the server before SAN/iQ creates the snapshot.

Timing for a scheduled remote snapshot

When you set up a schedule for recurring remote snapshots with the previous procedure, check the
time zone setting first. The time zone displayed in the Schedule to Remote Snapshot a Volume window
is the time zone of the storage system through which you first logged in to the management group.
See "Best practices for scheduling remote snapshots" on page 29.
