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 5):
The storage system according to  claim 4 ,\n wherein upon receiving a write request to the partition as well as write target data from the host computer, the storage controller allocates a first storage area of the storage device having the same size as the partition into the partition, and stores the write target data into the allocated first storage area, when the state of the partition is changed to the second state, the storage controller is configured to divide the partition into a plurality of deduplication blocks, allocate a data block which is a storage area different from the first storage area and has the same size as the deduplication block, for each deduplication block, and manage mapping between the deduplication block and the data block, and in allocation of the data block to a second deduplication block of the deduplication blocks, when the data written to the second deduplication block is the same as the data stored in a first data block allocated to a first deduplication block, the storage controller allocates the first data block to the second deduplication block.
