摘要： The data is automatically recovered to a desired arbitrary point in an external storage without imposing a burden on a host computer.
An application on a host computer instructs data recovery control processing of a disk control apparatus to set a recovery opportunity. It is made possible to register arbitrary plural points as recoverable point by setting a recovery flag included in journal data. In the case in which data is recovered due to occurrence of a failure or the like, the application requests a list showing recovery opportunities which have already been set. The application designates a point to which data is recovered on the basis of the recovery opportunity list. The disk control apparatus recovers the data to the designated point on the basis of a backup disk and a journal disk.

摘要： Disk units (4, 8) operable under control of different disk control units (3, 7) hold the same data. Under circumstances in which data is duplexed, when data is duplexed again after data that is generally saved as backup data was accessed for reading and writing, in order to efficiently duplex data, update places of both original data and sub-data updated during the duplexing of data is interrupted are registered on an access information management table (34) of an original disk control unit (3). When the original disk control unit (3) receives a duplexing resume command, the duplexing of data may be efficiently reorganized by copying original data corresponding to an access place produced during the duplexing is interrupted from information of the access information management table (34) to the backup data or by copying the backup data to the original data.
