A copy control apparatus for controlling a copy process between disks includes a copy process execution unit, a data capacity measuring unit, and a changing unit. The copy process execution unit executes the copy process between disks by securing a storage area on a cache. The data capacity measuring unit measures a data capacity contained in a write request accepted from a host system during execution of the copy process between disks by the copy process execution unit. The changing unit changes a capacity of the storage area secured by the copy process execution unit in accordance with the data capacity measured by the data capacity measuring unit.
