Snap back

Snap Back reattaches a detached snapshot mirror to its original volume.

After you are done using the snapshot, you can reattach it to the volume, where it is resynchronized to the datastore and continually updated. You can then get a current copy of the original volume, with minimal disruption to users, by issuing Snap Shot again.

Note:

Dynamic disks belonging to a Microsoft Disk Management Disk Group do not support the Snap Back command.

To reattach a snapshot mirror to the original volume

  1. Right-click the snapshot volume whose snapshot mirror you want to reattach to its original volume.

    A context menu is displayed.

  2. Select Snap > Snap Back.

    A dialog box appears with two options for resynching the snapshot.

  3. Specify whether the snapshot volume is to be resynchronized to match the original volume or the original volume is to be resynchronized to the snapshot volume, and click OK.

    One situation where you might want to resynchronize using the snapshot volume rather than the original volume is when something has happened to the original volume so that its data integrity is no longer sound.

    The middle of the screen displays a further explanation of the selected option.

    The snapshot mirror is reattached to the original volume, and the snapshot volume is deleted if it is the last plex of the volume. (If the snapshot volume has other associated mirrors, it is not deleted.)

    As shown in the following figure, the snapshot volume, identified as L in the previous figure, is removed from the Volumes folder in the tree view, and the snapshot mirror is now shown on the Mirrors tab for the original volume. After the resynchronization, the original volume is now in a similar situation as it was after the first Prepare command, but any changes to it have been updated on the snapshot mirror.

    Now it is possible to do another Snap Shot command on the volume and repeat the process. If you resynchronize to the original volume, the resynchronization should take very little time because that volume is constantly updated.

    Only the original synchronizing of the mirror in the original Prepare command takes the normal amount of time to create the snapshot mirror. Once you have completed the original Prepare command, the repeat procedure for Snap Shot and Snap Back are very quick. You have to do the Prepare command only once.

    Note that any mirrors that are added to the DCO volume of a snapshot volume are deleted when you snap back the snapshot volume.
