Volume Snapshots
  
Volume Snapshots
The cloud storage gateway can take snapshots of volumes. A volume snapshot is a read-only copy of a volume as it was at a particular point in time.
The cloud storage gateway automatically takes snapshots before performing a cloud backup or running an outgoing synchronization rule for a NEXT3 volume in order to ensure that a consistent image of all files is transmitted. In addition, you can schedule automatic daily snapshots and take snapshots manually.
You can use snapshots to access previous versions of your volumes and the files they contain.
The cloud storage gateway can take two types of snapshots: cloud snapshots and local snapshots on NEXT3™ volumes. NEXT3 snapshots are taken on a given volume if the volume is configured to support snapshots. It is recommended that you combine NEXT3 snapshots for fast recovery from non-disaster situations (such as an important file being accidentally overwritten by one of your office employees), with cloud snapshots for recovery from major disasters such as flood or fire.
Note: The snapshot mechanism is not supported for the XFS file system.
