Abstract: A data management apparatus of a computer system comprises, as a retention rule for volume data, change-time identification information for identifying a point-in-time for changing a logical unit, and migration-destination unit specification information for specifying a migration-destination logical unit. An edge storage apparatus stores first identification information, which enables the identification of volume data in a logical unit, and second identification information, which enables the identification of a logical unit in a storage system after associating the first identification information and the second identification information with each other. A data management apparatus (A1) transfers the volume data from a migration-source logical unit to the migration-destination logical unit conforming to the migration-destination unit specification information subsequent to a point-in-time identified in accordance with the change-time identification information. The edge storage apparatus (B1) associates the second identification information, which enables the identification of the migration-destination logical unit, with the first identification information, and stores the associated information in a storage device.

Abstract: Provided are a backup system and a backup method for backing up data written by a host into a logical volume provided by a storage system, wherein an update location in the logical volume updated by the host is managed, and the storage system is controlled to selectively back up the data written into the update location in the logical volume based on the management result of the update location. It is thereby possible to ensure a fast data read speed in the backup of raw volumes and an easy multiplatform backup, whereby a backup system and a backup method capable of performing backup efficiently are realized.
