What is SnapVault and how is it used?

• A. SnapVault is a primary volume snapshot repository for fast restores.
• B. SnapVault is a real-time replication channel for all data.
• C. SnapVault is a user authentication method.
• D. SnapVault is a secondary backup repository for SnapMirror data, enabling long-term retention and off-site copies.

Answer: (D)

SnapVault is a secondary backup repository for SnapMirror data, enabling long-term retention and off-site copies. It works alongside SnapMirror by storing incremental backups of the snapshot chain on a separate storage system, so you can keep older versions and have off-site copies for disaster recovery and compliance. You configure vault relationships and schedules to update the vault with deltas—avoiding the need to keep full replicas at the backup site. You can restore from the vault to recover specific points in time, or use it as the source for re-creating data at another site if needed. This is not the real-time replication channel for all data (that’s SnapMirror), nor is it a user authentication method or a primary local snapshot store for fast restores. It’s the durable, long-term backup target.
