Abstract: A restoration control apparatus for restoring a status of data arrangement on a destination storage device to a status of data arrangement on a source storage device before backup. The restoration control apparatus includes a determiner and a controller. The determiner determines whether a first storage area, where the backed up data is to be restored, on the destination storage device preserves prior data. Upon determining by the determiner that the first storage area does not preserve prior data, the controller stores the backed up data in the first storage area. Upon determining by the determiner that the first storage area preserves the prior data, the controller stores the backed up data in an unused second storage area on the destination storage device or copies the prior data preserved in the first storage area to the second storage area to store the backed up data in the first storage area.
