Abstract:
A data processing system includes a first storage system that is connected to a host device and sends and receives data to and from the host device; a second storage system that is connected to the first storage system and receives data from the first storage system; and a third storage system that is connected to the first storage system and receives data from the first storage system. The first storage system, the second storage system and the third storage system are arranged to be changeable between a first status including first and second copy pairs and a second status including a third copy pair in response to a predetermined condition at the first storage system.
