ABSTRACT:
Provided is a method for mirroring data. A mirror policy indicating volumes in a first storage system is processed to mirror to volumes in a second storage system and volumes in the second storage system to mirror to volumes in a third storage system. The third storage system is at a first geographical location remote with respect to a second geographical location including the first and second storage systems. A command is transmitted to cause the copying of updates to the volumes in the first storage system to corresponding volumes in the second storage system indicated in the mirror policy. Upon an occurrence of an event, the causing the suspension of the copying of updates to the volumes in the first storage system indicated in the mirroring policy to the volumes in the second storage system. During the suspension of the copying of volumes between the first and second storage systems, causing the copying of updates to the volumes in the second storage system indicated in the mirroring policy to the volumes in the third storage system indicated in the mirroring policy.
