Abstract
According to one embodiment, a file system includes a hash value calculator, an access controller and a deduplication controller. The hash value calculator calculates a hash value of at least one data block in a file to be stored in storage. The access controller stores, when the at least one data block includes a first data block and when a first hash value of the first data block is calculated, the first data block in a first location of the storage determined based on the first hash value, by using the first hash value as an identifier. The deduplication controller prevents the first data block from being stored in the first location when an effective second data block is already stored in the first location.
