Volume Snapshots : Manually Taking Snapshots
  
Manually Taking Snapshots
Note: Snapshots that are taken manually are retained until they are manually deleted.
1 In the Configuration tab, select Storage > Snapshots, and then select the desired NEXT3 snapshot-enabled volume.
2 Click Take Snapshot Now.
3 When the success message is displayed, click OK.
The snapshot is displayed in the lower pane.
Note: A snapshot retains all of the data that has changed on the volume since the snapshot was created. Therefore, the snapshot's size is zero upon creation, and its size grows as changes are made to the files on the volume.
