Which statement is true about SnapMirror and SnapRestore usage?

• A. The Volume Must Not Be the SnapMirror Destination
• B. The Volume Must Be the SnapMirror Destination
• C. The Volume Must Be the SnapMirror Source
• D. The Volume Must Be Offline

Answer: (A)

SnapMirror keeps a replica of a source volume on a separate destination to stay in sync, while SnapRestore reverts a volume to a previous snapshot. If you SnapRestore the SnapMirror destination, you overwrite the mirrored copy and break the synchronization with the source, leading to divergence. Because of that, the volume involved in a SnapMirror relationship should not be the one you SnapRestore. In practice, you restore the source (or break the mirror and reinitialize after recovery) rather than restoring the destination. This is why the statement that the volume must not be the SnapMirror destination is the true one. The other options don’t reflect this constraint.
