SnapVault differs from SnapMirror in that it:

• A. Maintains versioned, long-term backups for compliance
• B. Provides synchronous replication between active sites
• C. Acts as a performance cache for origin volumes
• D. Allows writable mirrors for testing

Answer: (A)

The main idea here is understanding what SnapVault is designed to do: provide versioned, long-term backups for retention and compliance. SnapVault uses Snapshot-based backups from a source system and stores multiple versions over time on a vault destination, enabling point-in-time recovery and meeting archival requirements. It isn’t about keeping a live, writable copy for fast failover or testing; instead, it focuses on durable backup history that can be retained for extended periods. That’s why this choice is the best description. SnapMirror, by contrast, is about maintaining a live or near-live replica for disaster recovery—often enabling quick failover—whereas SnapVault emphasizes long-term, versioned backups. The other statements don’t fit SnapVault: synchronous replication is a SnapMirror capability, not a SnapVault backup mechanism; using SnapVault as a performance cache isn’t its purpose; and SnapVault backups aren’t writable mirrors used for testing.
