Enabling Snapshots
You can use the snapshot feature to create a read-only point-in-time copy of a file

2. You must enable Snapshots before launching the software. Select Snapshots.
In the resulting screen, the Status field indicates whether the software is
enabled. If Disabled appears, select Actions > Enable/Disable Application.

window (on the Storage tab), you can access the following capabilities:

See Using Snapshots on page 135 for more information.
Creating a Snapshot
You can use the snapshot feature to create a read-only point-in-time copy of a file
volume.
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 create snapshots on a high-availability system, select the node that is running
the associated failover package.
To create a new snapshot:
1. In Command View NAS, click the Storage tab.
2. Under Snapshots, select Snapshot Summary.
3. Select Actions > Create New 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.
