Scheduling a Snapshot
On the Snapshots Scheduler page, a table displays the following information for
each scheduled snapshot on the NAS server:
■
Snapshot name
■
File volume name of the snapshot
■
Size allocated to the snapshot
■
Auto grow enabled
■
Frequency of re-occurrence of the snapshot
■
Scheduled time of the snapshot
■
Expiration date of the snapshot
When you schedule a snapshot, make sure your NAS server will have sufficient
space to accommodate the snapshot. (The system does not pre-allocate space and
assumes that space will be available at the time the snapshot is scheduled to take
place.) If space is not available on the volume group at the time the snapshot is
scheduled to occur, the snapshot will fail. To ensure that you have sufficient space,
you can view the Volume Groups page.
You should carefully plan snapshots to occur immediately before the creation of a
disaster recovery file (DRF). If snapshot(s) of file volumes are taken after DRF
creation and an outage occurs, snapshot(s) will not be recovered and any storage
space used by the snapshot(s) will be lost. See
Recovering from a Disaster for
more information.
Note: To schedule snapshots on a high-availability system, select the node that is
running the associated failover package.
To create a scheduled snapshot:
1. In Command View NAS, click the Storage tab.
2. Under Snapshots, select Snapshot Scheduler.
3. Select Actions > Create New Scheduled Snapshot.
4. Select the file volume you want to take a snapshot of from the File Volume
drop-down list.
5. Enter a Snapshot Name.
