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.

摘要： The present invention is able to improve the processing performance of a storage system by respectively virtualizing the external volumes and enabling the shared use of such external volumes by a plurality of available virtualization storage devices. By virtualizing and incorporating the external volume of an external storage device, a first virtualization storage device is able to provide the volume to a host as though it is an internal volume. When the load of the first virtualization storage device increases, a second virtualization storage device 2 is newly introduced, and connected to the storage system. When a transfer direction is issued from a management terminal, the external volume relating to the selected logical volume is transferred from the first virtualization storage device to the second virtualization storage device.
