Abstract
Duplicate storage elimination is performed in units of block data generated by dividing a data stream into arbitrary-sized blocks. Further, sub-block data is generated by further dividing the block data into a plurality of pieces of data, and sub-address data based on the data content of each of the pieces of sub-block data is stored in a predetermined storage device. As such, duplicate storage elimination is also performed in sub-block data units based on the sub-address data.
