摘要： Two data centers located in the vicinity are connected using a synchronous transfer copy function, and one of the data centers is coupled with a third data center disposed at a remote location by an asynchronous remote copying function. The order whereat a storage sub-system located in the vicinity has received data from a host is consistently guaranteed, and the third data center holds the data. Further, each storage sub-system includes a function whereby, during normal operation, data can be exchanged and the data update state can be obtained by the storage sub-systems located in the two data centers that do not directly engage in data transmission.

摘要： In a storage system, a logical volume is divided into a plurality of small areas called logical storage devices and only such an area designated by a user is made an object of remote copying or migratory copying. Also, there is provided a unit for forming a logical volume from any logical storage device of any RAID group. Thereby, the reduction of the deterioration in performance at the time of remote copying, the reduction of a storage area to be assigned to a secondary site as a copy destination, the shortening of a time required for migratory copying and the assignment of any area of a logical volume on any RAID group are enabled.

摘要： In an information processing system including a central processor for generating commands to process storage data stored and for executing a sequence processing and a storage subsystem including a plurality of storage media for transferring data between the plural storage media according to commands from the central processor, a data recovery method recovers data to a predetermined state upon occurrence of a failure in a sequence of processing executed by the central processor. Before execution of a sequence of processing, the central processor issues to the storage subsystem a saving request to save in the plural storage media a copy of data stored in either one of the storage media used in the sequence of processing. In response to the saving request, the storage subsystem saves a copy of data of the storage media.

摘要： The following steps are performed in a storage system: when volumes configuring each volume pair are used by separate applications, storing, for each pair in a memory, an address where updating of data has been made in the volumes as updated-location-managing information; in case a destination-of-restoring copy volume configuring one pair is to be restored to have the contents of a source-for-restoring copy volume belonging to another pair, obtaining, from the memory, pieces of the updated-location-managing information for each of the pairs; generating differential information by merging the pieces of updated-location-managing information obtained, the differential information indicative of a difference in the pieces of updated-location-managing information between the copy volumes; and reproducing the destination-of-restoring copy volume to have the contents of the source-for-restoring copy volume, by copying data designated by the differential information from the source-for-restoring copy volume to the destination-of-restoring copy volume.

摘要： A method of managing a generation of backup data in a storage system is carried out by a storage control device. The backup data is data generated in each of a plurality of pairs originating from one volume. The method includes: receiving, from a host computer, a split request for stopping synchronization between a primary volume and a secondary volume in one of the pairs, and version information about the split; performing a split process in which a backup between the primary volume and the secondary volume of the pair is performed in response to the split request and the synchronization of the pair is stopped; and storing, for each pair, version information of the split process in a predetermined storage section.
