Abstract
The present invention allows a back-up site used for disaster recovery to be constructed in a shorter period of time. In a disk array deviceat a main site, a copyof a RAID groupis generated. In-frame mirroring is used to generate this copy. The RAID groupis removed from the disk array deviceby an operator and transported to a back-up site. The operator then installs each of the disks of the RAID group, respectively, in the disk array device, in such a manner that they adopt the same positions as in the RAID group. The configuration informationused in order to manage the RAID groupis downloaded to the disk array devicein the back-up site, by means of a portable storage medium, or via a communications network. Thereupon, the differential data between the disk array devicesis reflected in the disk array device, whereupon construction of the back-up site is complete.
