摘要： A first storage control device is provided with a virtual LU for showing a logical volume possessed by a second storage control device as if it were its own volume. When data processing requested from a host device is, for example, a specific processing of large load (such as direct backup, logical volume copy, and so on), whether or not the requested processing can be executed by the second storage control device is judged. When it is executable, a command is transmitted to the second storage control device to make it take over the processing.

摘要： A DBMS performs a checkpoint process for maintaining consistency of data. A snapshot acquisition control program detects the checkpoint process externally to the DBMS and creates a snapshot in an external storage according to the timing of the checkpoint. Correspondence between checkpoints and snapshots is maintained in a CP-SH correspondence management table to make it possible to restore in a short time data at the time of an arbitrary checkpoint.

摘要： 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.
