摘要： Disk units operable under control of different disk control units 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 of an original disk control unit. When the original disk control unit 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 to the backup data or by copying the backup data to the original data.

摘要： A data processing system includes at least a first storage system, a second storage system and a third storage system. The third storage system maintains a replication of data stored in the first storage system. When updating data in the first storage system, the first storage system updates the replication of data stored in the third storage system and creates a journal. The journal is formed from a copy of data used for update and update information such as a write command for update, etc. The second storage system also maintains a replication of data stored in the first storage system. The second storage system obtains the journal, and updates data stored therein corresponding to data stored in the first storage system in the order of data update performed in the first storage system. When updating data stored in the third storage system corresponding to data stored in the first storage system, the third storage system creates a journal using data update numbers created in the first storage system. When the first storage system fails, the second storage system obtains the journal from the third storage system, and updates data stored therein corresponding to data stored in the first storage system in the order of data update performed in the first storage system.

摘要： A data processing system has a plurality of storage systems. In this system, data replication is performed at high speed and efficiency while maintaining data integrity. In addition, when failure has occurred in a configuration element, the time necessary to resume the data replication is reduced. In accordance with an instruction from first host computer, updating of replication-target data and creation of a journal are performed in a storage system A; and updating of replication data and creation of a journal are performed in a storage system B. A storage system C retrieves a journal from the storage system B in asynchronization with the updating, and performs updating of replication data. When failure has occurred in the storage system B, a journal-retrieving end is altered to the storage system, and the replication data is updated in accordance with the retrieved journal.

摘要： The data is automatically recovered to a desired arbitrary point in an external storage without imposing a burden on the 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 possible to register arbitrary plural points as a 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.
