Patent 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.
