Volume Replicator snapback operation reattaches the plexes of the snapshot volumes back to the original data volumes in the RVG. Even if the snapback operation fails for one or more volumes, it continues to snapback the remaining volumes. This is unlike the snapshot operation. After the operation completes successfully for some of the volumes, appropriate error messages with names of the volumes for which the snapback operation failed along with the reasons for the failure, are displayed.

The default action of the snapback operation is to resynchronize the snapshot plex with the contents of the original volume. However, if the data on the original volume becomes unavailable due to corruption or some software error, you need to recover the lost data. This can be done by performing the snapback operation with the option of resynchronizing the original volume with the contents from the snapshot plex.

For information about using the Volume Replicator snapback operation from the command line,

Creating snapshots works on any type of file system and should be used when a point-in-time copy of volume is required. Otherwise, you can also create the data volumes with mirrors and break-off the mirrors to create a separate volume which is a point-in-time copy of the data.
