摘要： To provide a storage management device capable of performing restore at a high speed. In the storage management device that manages backup and restore of data stored in a storage device, a temporary restored image is created by applying each required delta image to the full backup image, a reverse delta image before the application of the applied delta image is created, and a number of delta application blocks concerning the applied delta image is recorded as cost information of applying delta. The delta backup restore unit determines a restore method by comparing a number of blocks, which is changed when restore is performed by applying each piece of the reverse delta image, with a number of blocks, which is changed when the restore is performed by applying each delta image, with reference to the cost information of applying delta.

摘要： A backup system is configured by interconnecting a backup management device and disk array device via a SAN. The backup management device allows an administrator to set backup cycle, number of backup generations, and save periods. On the basis of these settings, the backup management device performs an overwrite decision process, and executes backup processes in such a way that the administrator can manage the desired number of generations of backup data with a limited number of volumes. By so doing, the administrator is able to manage multiple generations of backup data, while being allowed to set the save period for each generation on an individual basis.

摘要： This storage system modifies the migration plan in accordance with the state of the migration destination when a plurality of volumes are migrated all at once. Migration-source volumes are migrated collectively to volumes inside the migration-destination storage apparatus. The user can make settings related to migration-source volumes and migration-destination volumes in a migration plan, and can establish a mid-process control plan for modifying the migration plan in the middle of processing. If a failure occurs in the migration-destination storage apparatus subsequent to the commencement of data migration processing, a processing method controller either cancels or temporarily halts the data migration processing, or changes the migration destination, on the basis of the mid-process control plan. When changing the migration destination, a previously selected alternate storage apparatus is selected as the new migration-destination storage apparatus. When a failure occurs in the alternate storage apparatus, yet another alternate storage apparatus is selected.

摘要： A computer system includes a host computer; a storage system for obtaining a snapshot, at a specific point in time, of a data volume, storing data written to the data volume after the specific point in time as a journal, and applying the journal to the snapshot for data recovery; and a management computer. In the computer system, the management computer instructs the storage system to determine whether data at a recovery point after a recovery point of the latest snapshot can be recovered within a specific period of time and to apply, if it has been determined that the data cannot be recovered within the specific period of time, a journal to the latest snapshot to update the latest snapshot to a new snapshot in such a manner that the data can be recovered within the specific period of time
