Which NetApp solution provides zero RPO and near-zero RTO for NAS workloads?

• A. storage VM disaster recovery (SVM DR)
• B. MetroCluster over IP
• C. SnapMirror Business Continuity (SMBC)
• D. SnapMirror Synchronous (SM-S)

Answer: (C)

Zero RPO and near-zero RTO for NAS workloads come from having a DR setup that keeps a continuously updated, consistent copy of NAS data at a remote site and can switch over to it automatically with minimal downtime. SnapMirror Business Continuity delivers this by driving continuous SnapMirror replication for NAS data and providing orchestrated, automated failover and failback. With SMBC, the remote copy stays up to date, so there’s no data loss at failover, and the recovery process is streamlined and rapid, yielding the near-zero downtime NAS clients expect.

Other options tend to focus on different aspects or scales of DR. SVM DR operates at the SVM level and doesn’t always cover the full NAS data set with the same automated continuity guarantees. MetroCluster over IP is a powerful, more complex DR solution that can also achieve zero RPO, but its larger footprint and deployment requirements make SMBC a more practical choice for many NAS environments seeking seamless continuity. SnapMirror Synchronous can provide true zero RPO, but is typically more constrained by geography and deployment specifics; SMBC is designed to deliver NAS-focused business continuity with continuous replication and automated failover, aligning with the goal of zero RPO and near-zero RTO.
