Which NetApp feature allows recovery verification of snapshots without affecting production data?

NetApp FlexClone technology creates a writable, space-efficient, point-in-time copy of a volume, LUN, or file from an existing Snapshot copy. This cloned volume is independent of the production volume and can be mounted to a test server. This allows administrators to perform recovery verification, application testing, or data analysis on the cloned data without any performance impact or risk to the live production environment. The clone is created almost instantly and consumes minimal additional storage space initially.

A. SnapMirror Sync: This is a synchronous data replication technology for zero data loss disaster recovery, not for testing or verifying snapshot integrity.

C. MetroCluster Failover: This is a high-availability solution that provides continuous data access by failing over to a secondary site; it is not used for snapshot verification.

D. SnapRestore Batch: This feature restores multiple files or LUNs from a snapshot directly into the production volume, which is a disruptive action, not a verification method.
