<p>There are provided a mainframe 1 constituting a host device and a disk array system 2 having logical volumes (LDEV) 30 connected with the mainframe 1. The mainframe 1 is provided with an input/output device configuration definition information storage section 14 that stores the address of an LDEV 30a. By referring to the input/output device configuration definition information storage section 14, a command is then issued giving an instruction to perform back-up of the LDEV 30a specifying the address of the LDEV 30a. The disk array system 2 receives the back-up command, specifies the generation to which the LDEV 30a is to be backed up and backs up to an LDEV 30b to 30d corresponding to the specified generation.</p> |
