Remote Mirroring

A remote mirror volume is a mirror volume with a source in another cluster. You can use remote mirrors for offsite backup, for data transfer to remote facilities, and for load and latency balancing for large websites. By mirroring the cluster's root volume and all other volumes in the cluster, you can create an entire mirrored cluster that keeps in sync with the source cluster.

Backup mirrors for disaster recovery can be located on physical media outside the cluster or in a remote cluster. In the event of a disaster affecting the source cluster, you can check the time of last successful synchronization to determine how current the backup is (see Mirror Status below).

The following sections provide information about how to create and use remote mirroring:
