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 1):
A storage system comprising:\n 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, wherein the storage controller holds the last write time which is the time when a write request is last received from the host computer for each partition within the volume, and with respect to the partition not receiving a write request for a predetermined time or more from the last write time, when the same data as the data written to the partition from the host has been stored in the storage device, the storage controller performs a deduplication process so as not to store the data that is written to the partition into the storage device.
