What is a Snapshot copy primarily used for?

• A. A tape backup
• B. A clone used for testing
• C. A read-only folder
• D. Point-in-time copy of a volume used for quick restores, data protection, and DR; can be scheduled or created on-demand

Answer: (D)

Snapshots provide a point-in-time view of a volume to support quick restores, data protection, and disaster recovery. They’re created rapidly and are space-efficient because NetApp uses a copy-on-write mechanism, so the active data and the snapshot share blocks until changes occur. You can schedule snapshots to run automatically or create them on-demand when you need a restore point. From a snapshot, you can revert the volume to that exact state or clone it for testing without touching the production data. They’re not a tape backup, and a snapshot itself isn’t a clone or a read-only folder, though you can derive a clone from a snapshot if you need a separate test environment.
