PROBLEM TO BE SOLVED: To comparatively easily use latest data to recover data. SOLUTION: Data is remotely copied to an intermediate volume 260SP from a backup source volume 260P. When access by a host 30 is completed and when backup time arrives, the data is locally copied to a backup destination volume 260S from the intermediate volume 260SP. In time of the data recovery, a recovery source list presentation screen similar to a local copy management screen is created. A user can select each backup destination volume 260S, and also the intermediate volume 260SP as a recovery source candidate. COPYRIGHT: (C)2011,JPO&INPIT
