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 7):
A method for controlling a storage system,\n wherein the storage system 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, the storage controller performs: a step of recording the last write time which is the time when a write request is last received from the host computer; a step of detecting the partition not receiving a write request for a predetermined time or more from the last write time; and a step of performing a deduplication process on the detected partition in such a way that, of the data written to the partition, only data different from data already stored in the storage device is stored in the storage device.
