Abstract:
The control device acquires the archive deadline of archive target data and acquires, for storage devices of a plurality of types, a warranty deadline for the quality of data stored by the storage device and the unit cost which is the cost for each predetermined storage size of the storage device. The storage control device is a storage device which acquires a data migration cost and which obtains a storage destination for the archive target data from storage devices of a plurality of types on the basis of the archive deadline, warranty deadline, unit cost and data migration cost thus acquired. The storage control device selects a storage device for which the total cost is minimum when the archive target data is archived until the archive deadline.
