摘要： PROBLEM TO BE SOLVED: To efficiently use a storage region by efficiently managing difference data to be held when providing a snap shot function. SOLUTION: In acquiring a snapshot, when data in a P-VOL 22 is updated, it is determined whether the same data as target data to be stored in a second storage area specified by a second address of a D-VOL 23 is already stored in a different second storage area specified by a different second address of the D-VOL 23, the target data being the differential data generated by the update. When the same data as the target data is stored, the target data is not newly stored in the D-VOL 23, and the different second address, specifying the different second storage area where the same data is stored, is registered in a snapshot management table (CoW table 131), in association with a first address where the target data has been stored.

摘要： PROBLEM TO BE SOLVED: To provide a technique that implements a snapshot function capable of reducing a drop in the data access performance of an operated storage by reducing data transfer between a server device and a storage device necessary to copy data in the storage. SOLUTION: In a storage system, a command processed by a CPU 112 of the storage device 111 includes a Copy and Write command to execute data copy processing and data storage processing in a predetermined order. The server device 101 issues the command to the storage device 111. Upon receiving the command, the storage device 111 first executes the data copy processing from a disk drive 117 to a disk drive 118 and next executes the data storage processing to the disk drive 117 to maintain a snapshot of data stored in the disk drive 118.

摘要： PROBLEM TO BE SOLVED: To back-up a disk array system equipped with a network server function and a storage area network function in a path which does not overlap with data other than back-up data easily at high speed without giving a load to a LAN. SOLUTION: When a network file server module 2 receives a back-up request, a back-up file 14 is copied in a back-up volume 12 from ordinary volumes 10 and 11 of the disk array system and, when copying is completed, a copying request to an external storage device 9 is notified to the storage area network module 3. The storage area network module 3 which receives the notice copies the back-up volume 12 at that time in the external storage device 9. COPYRIGHT: (C)2004,JPO
