<p>A storage device includes a data division unit (201) that divides data into data blocks, a duplicate storage determining unit (203) that determines whether the same data block as that to be stored has been stored in a storage unit (34) for discharge in an export process, and a data storage processing unit (206) that stores the data block to be stored in the storage unit (34) for discharge when the same data block has not been stored in the storage unit (34) for discharge and prevents the data block to be stored from being stored in the storage unit (34) for discharge when the same data block has been stored in the storage unit (34) for discharge. According to the storage device, it is possible to reduce the amount of data stored in the storage unit for discharge.</p> |
