<p>A determining unit selects one storage device each from storage devices of an external storage apparatus and storage devices of a storage apparatus to which the determining unit belongs. At this point, based on a copy request, the determining unit preferentially selects, within each of the external storage apparatus and the storage apparatus, a storage device including a larger number of logical volumes (LVs) which belong to copy unexecuted LV pairs compared to other storage devices therein. Further, the determining unit determines, as a copy execution target, a copy unexecuted LV pair in which a LV provided in one of the selected two storage devices is a copy source and a LV provided in the other storage device is a copy destination. A copy unit copies data stored in the copy source LV, which belongs to the determined LV pair, to the copy destination LV of the LV pair.</p> |
