Abstract
Whether a replication relationship is established between a first and a second storage device is determined. If it is determined that the replication relationship is established between the first and second storage device, then whether data in the first region of the first storage device has changed since a previously completed asynchronous data replication process is determined. If the data in the first region of the first storage device has changed since the previously completed asynchronous data replication process, then whether the changed data in the first storage device is data copied from the second region of the first storage device is determined. If the changed data in the first region of the first storage device is data copied from the second region of the first storage device, then data from the second region of the second storage device is replicated to the first region of the second storage device.
