摘要： Multiple storage area groups into which multiple storage areas provided by multiple storage devices are classified with reference to storage area attributes are managed. The multiple logical volumes to which, in accordance with a write request to at least one address included in multiple addresses in the logical volume, at least one storage area included in the multiple storage areas is allocated are provided. In accordance with the access condition of the at least one address in the logical volume, the data written to the at least one address by the write request is migrated from the at least one storage area included in one of the multiple storage area groups to at least one storage area in another storage area group included in the multiple storage area groups.

摘要： Provided are a computer system and its data control method that enable safe backup of data and reduction in the capacity of data to be backed up. A control processor refers to a differential and, if a differential bit is “0,” encrypts data of an online VOL with an encryption circuit by using key information, and transfers the encrypted data to a second storage system. If the differential bit is “1,” the control processor performs redundancy elimination processing to journal data, thereafter compresses the journal data with a compression circuit, encrypts the compressed journal data with an encryption circuit according to the key information, and transfers the journal data that was encrypted after compression to the second storage system.

摘要： When a computer 10 receives a request from the client computer 30 to access snapshot files, the target device to be used is identified. The computer 10 makes a request to the identified target device TD for attachment of the logical device LDEV that stores the snapshot files for which access is requested. When the computer 10 receives notification that the attachment has ended from the storage device system 20, the identified target device is mounted on the directory in which the snapshot files are stored.

摘要： In a storage system having a plurality of control units each connected with a plurality of disk units, it is provided that a replication is created in the volume of the disk units connected to different control units. The replication creation unit of a given control unit creates a replication in the volume of the disk unit connected to other control units in such a manner that the original volume information, the replication volume information in the control unit and information on the other control units are registered as volume pair information. Based on this volume pair information, a replication creation request is transmitted to the other control units.

摘要： In a storage system comprising multiple storage devices with different interfaces, the characteristics, including the type of interface, of the storage devices on which the source volume is constructed are checked, a volume having the characteristics that match them is selected as the destination volume, and the contents of the source volume are automatically replicated into the destination volume. Candidates for replication (destination) volumes are automatically selected and presented to the user or the administrator, and replication volumes are automatically allocated, without requiring the user or the system administrator to be concerned with the characteristics of the storage devices.
