You can create a mirror relationship to a destination within a cluster to protect your data or, for greater disaster protection, you can create a mirror relationship to a destination in a different cluster in a different location.
You can create data protection mirror relationships to destinations on the same aggregate as the source volume, and on the same Storage Virtual Machine (SVM) or on a different SVM. For greater protection, you can create the relationships to destinations on a different aggregate, which enables you to recover from the failure of the source volume's aggregate. Neither of these two configurations protects against a cluster failure.
To protect against a cluster failure, you can create a data protection mirror relationship in which the source volume is on one cluster and the destination volume is on a different cluster. If the cluster on which the source volume resides experiences a disaster, you can direct user clients to the destination volume on the cluster peer until the source volume is available again.
You can also use mirror relationships for limited disaster recovery, off-loading tape backup, data distribution, and making offline copies of production data for research, such as data mining.
