Which statement is NOT a prerequisite for using SnapRestore?

• A. The Volume to be Reverted Must Not Be a SnapMirror Destination
• B. Snapshot Copies Must Exist on the Storage System So That You Can Select a Snapshot for the Reversion
• C. You Must Enter the SnapRestore License Code Before You Can Use It
• D. The Volume to be Reverted Must Be Offline

Answer: (D)

SnapRestore works by restoring a volume from a snapshot, overwriting its current data with the snapshot contents. Because this process uses the snapshot data, you can perform the restore while the volume is online, so downtime is not required. The idea that the volume must be offline is not a prerequisite, which is why this statement is the one that isn’t needed. There are still real prerequisites to be aware of. A volume that is a SnapMirror destination cannot be used for SnapRestore, since restoring would interfere with the mirrored relationship. You must have an existing snapshot on the storage system to select as the restore target. And SnapRestore is a licensed feature, so you need the appropriate license code enabled before you can use it.
