Volume disaster recovery preparation overview
You can quickly protect a source volume on a peered ONTAP cluster in preparation for disaster recovery. You should use this content if you want to configure and monitor SnapMirror relationships between peered clusters for volume disaster recovery and do not need a lot of conceptual background for the tasks.
SnapMirror provides scheduled asynchronous, block-level data protection. SnapMirror replicates Snapshot copies and can replicate NAS or SAN volumes on which deduplication, data compression, or both are run, including volumes containing qtrees and LUNs. SnapMirror configuration information is stored in a database that ONTAP replicates to all the nodes in the cluster.
Use this procedure if you want to create SnapMirror relationships for volume-level disaster recovery in the following way:
You are working with clusters running ONTAP 9.
You are a cluster administrator.
You have configured the cluster peer relationship and the SVM peer relationship.
You have enabled the SnapMirror license on both the source and the destination clusters.
You want to use default policies and schedules, and not create custom policies.
You want to use best practices, not explore every available option (ONTAP 9.7 and earlier).
If these assumptions are not correct for your situation, or if you want more conceptual background information, you should see the following resources:
