You can perform online backup and recovery of volumes using any of several Data ONTAP features.
Data ONTAP provides the following features for traditional and FlexVol volumes to help you back up and recover data:
Makes a read-only image of a file system volume on the same disk.
Restores data to a corrupted volume from a previous Snapshot copy.
Maintains a replica of one volume in another volume and one qtree in another qtree.
Keeps copies of volumes on the server, from which individual qtrees are available to the client at any time, for long periods of time.
Copies data from one volume to another.
Maintains two identical copies of a volume at all times.
