Abstract
A first computer having a first interface connected to a backup storage device, and a second computer having a second interface differing in format from the first interface share a common storage device which can be connected to either the first interface or the second interface. The first and second computers are connected to the shared storage device via a storage device controller. In response to a data access command issued to the shared storage device by either the first computer or the second computer, the storage device controller converts a data address specified by the data access command to a data address used within the shared storage device. By using the data address obtained by the conversion, the shared storage device is accessed. The first computer creates, in the backup storage device, a backup of data stored in the shared storage device via the storage device controller.
