Restore a Volume from a Snapshot

NOTE: For synchronously-replicated volumes, you must first unconfigure synchronous replication before you attempt to restore the volume.

You can restore a volume from one of its snapshots. Before it is restored, a new snapshot is automatically taken of the existing state of the volume, even if third-party software is used.

You can restore a volume from either the local recovery point or the remote recovery point. The local recovery point is the last local snapshot taken for the volume. The remote recovery point is the last snapshot taken through replication.

After a volume is restored from a snapshot, the automatically created snapshot appears in the list of snapshots for the volume, and is identified with the original snapshot’s name appended with a timestamp of the date and time it was taken.

NOTE: When restoring a volume, it is recommended that you unmount the volume from the host before putting the restored snapshot online. Restoring a volume without stopping all host access can cause data corruption and system errors.
  1. Choose Manage → Data Storage.
  2. Select the volume that you want to restore.
  3. On the volume details page, click the Data Protection tab.
  4. Check the snapshot that you want to use to restore the volume.
  5. Click Restore.
    A warning displays asking if you want to take the volume offline (if it is online). You should check Set volume offline, otherwise the operation fails.
  6. Click OK to acknowledge the warning.
Set the volume online. See Change the State of a Volume.
