Why each option
SnapMirror provides asynchronous disaster recovery replication of FlexVol volumes, allowing clients to fail over to the mirror replica if the source is lost. It is not designed for a traditional backup-restore workflow back to the original source.
SnapMirror's primary use case is disaster recovery - it continuously replicates data to a secondary site so workloads can resume if the primary fails.
SnapMirror is not designed for restoring data from a secondary back to a primary; that restore workflow is associated with SnapVault (backup) relationships, not SnapMirror DR relationships.
SnapMirror operates asynchronously by default, periodically transferring Snapshot copies from the source FlexVol to the destination replica to minimize RPO.
When the source volume is lost or destroyed, SnapMirror allows clients to be redirected to the destination (mirror) volume, which contains a consistent copy of the data.
