Abstract
A storage system according to the present invention includes: a block detecting means for checking whether respective block data obtained by division are already stored in a storage device; and a data writing means for storing the respective block data obtained by division with duplicated storage eliminated into the storage device. The block detecting means detects a share rate representing a rate of a shared portion between a plurality of consecutive block data configuring a predetermined range in write target data among the block data obtained by division and a plurality of block data in a predetermined range already stored consecutively in the storage device. The data writing means, depending on the detected share rate, newly stores the block data obtained by division, into the storage device.
