    摘要: Proposed are a storage apparatus and its control method capable of restoring data of a virtual page to an appropriate device hierarchy according to its data value. This storage apparatus stores, in a backup-destination storage medium, data stored in the respective physical pages allocated with the virtual volume and management information of the virtual volume including information concerning the device hierarchy to which the respective physical pages belong according to a backup command of the virtual volume, and allocates a physical page of the same device hierarchy as the device hierarchy of the physical page that was allocated before the backup to each of the restoration-target virtual pages of the virtual volume, respectively, and writes corresponding data, which was read from the storage medium, into each of the allocated physical pages according to a restoration command of the virtual volume and based on the management information of the virtual volume stored in the storage medium.

    摘要: The present invention enables a unified way of accessing files generated by application programs configured to store contents in files in different formats, without using a conversion program.A database for holding correspondence between an identifier of a content and a storage position of the content is generated based on a backup catalog generated by a backup server, and contents are accessed by using this database. Contents generated by a plurality of different application programs are accessed in a unified way using a single name space.

    摘要: A secondary subsystem reads first differential data recorded in a magnetic tape device into a magnetic disk device, and manages such data based on second differential data that was created based on the read first differential data and differential management information. Then, whether differential data exists in partial data is determined based on the differential management information, and, if such differential data exists, the partial data is read into a cache memory, and differential data is applied to the partial data. Meanwhile, if differential data does not exist, the partial data is read into the buffer. Moreover, new full data is recorded by writing the partial data, which was read into the cache memory or the buffer, onto the magnetic tape device in parallel with other read processing.

    摘要: A storage apparatus installed in a first site generates a snapshot of a copy source logical device in an intermediate logical device. Next, an external storage apparatus including a logical device corresponding to the intermediate logical device is disconnected from the first site and connected to the second site. A storage apparatus in the second site is made to recognize the logical device in the external storage device as a logical device of a remote copy target. Next, the storage apparatus instructs the second site about writing in the copy target logical device through a global network on the basis of the difference data managed with the bit map.
