What is SnapMirror best used for in DR planning?

• A. Archival storage only.
• B. Replicate data to DR site and keep it up-to-date for quick failover.
• C. Local only; not suitable for DR.
• D. For orchestrating cluster upgrades.

Answer: (B)

SnapMirror is designed to keep a copy of your data at a remote DR site up to date so you can switch over quickly if the primary site goes down. In DR planning, its main use is to replicate data to the DR site and maintain current data so failover can happen with minimal or no data loss, depending on the replication mode and frequency. The replication can run asynchronously to balance bandwidth and recovery objectives, and you can test DR failover and failback without impacting the primary site. It’s not about archival storage, nor is it limited to local protection, and orchestrating cluster upgrades is a different capability.
