Abstract
In a storage device, an information acquisition unit acquires and stores information in an information memory unit. A data acquisition unit acquires data. A deduplication unit divides the acquired data by a smaller division size than that indicated in additional information included in the information stored in the information memory unit, performs deduplication, and stores the resulting data in a data memory unit. The information memory unit stores the information including the additional information that indicates the division size used for dividing data in deduplication of another device.
