Why each option
SnapMirror provides data protection for disaster recovery by asynchronously replicating FlexVol volumes, allowing clients to connect directly to the mirror image if the source is lost.
SnapMirror is a core replication technology designed specifically to provide robust data protection and enable disaster recovery solutions, ensuring business continuity.
SnapMirror does not typically involve restoring data from the secondary to the primary in a client-initiated manner; instead, clients access the secondary directly or the secondary becomes the new primary.
SnapMirror supports asynchronous replication, where data changes are copied to the disaster recovery replica with a slight delay, which minimizes performance impact on the primary source volume.
In the event of a source FlexVol volume loss or destruction, SnapMirror allows clients to connect directly to the mirror image on the destination, facilitating rapid data access and recovery.
