ABSTRACT:
In a configuration in which it is necessary to transfer data from a first storage system to a third storage system through a storage system between the storage systems, there is a problem that it is inevitable to give an excess logical volume to a second storage system between the storage systems. A remote copy system includes first storage system that sends and receives data to and from an information processing apparatus, a second storage system, and a third storage system. The second storage system virtually has a second storage area in which the data should be written and has a third storage area in which the data written in the second storage area and update information concerning the data are written. Data sent from the first storage system is not written in the second storage area but is written in the third storage area as data and update information. The data and the update information written in the third storage area are read out from the third storage system.
