Abstract:
A storage system according to an aspect of the present invention includes one or more storage devices for storing write data to which a write request from a host computer is directed, and a storage controller that provides one or more volumes to the host computer. Further, the storage system manages the time when a write request is last received from the host computer for each partition within the volume. Then, the storage controller performs a deduplication process upon detecting the partition not receiving a write request for a predetermined time or more from the time when the write request is last received.

Claim (Index 6):
The storage system according to  claim 5 ,\n wherein the storage controller calculates a feature amount of the data written to the deduplication block, and records the mapping between the calculated feature amount and the data block allocated to the deduplication block, and after the calculation of the feature amount of the second deduplication block, when the same value as the feature amount of the second deduplication block is not stored in the search table, the storage controller allocates a second data block to the second deduplication block and stores the data written to the second deduplication block into the second data block.
