Abstract
In a storage system a first control device can restore in a restoration destination storage device a second set of data stored in a second storage device on the basis of a first set of data stored in a first storage device. A third storage device stores progress information indicative of the progress of restoration performed by a first control device. A second control device restores a portion of the second set of data which is not yet restored on the basis of the progress information stored in the third storage device at the time of detecting that the first control device has stopped.
