A first storage subsystem 100 A comprises a first storage device 6 A 1 and one or more second storage devices 6 A 2, 6 A 3 . A second storage subsystem 100 B comprises a third storage device 6 B 1 and a fourth storage device 6 B 2 . A third storage subsystem 100 C comprises a fifth storage device 6 C 1 and a sixth storage device 6 C 2 . The first storage subsystem 100 A generates a data set, stores the generated data set in the second storage devices 6 A 2, 6 A 3 , and transmits the data set to the second and third storage subsystems 100 B, 100 C. Each of the second and third storage subsystems 100 B, 100 C stores the received data set in the third storage device 6 B 1 or fifth storage device 6 C 1 , reads a data set from the third or fifth storage device 6 B 1, 6 C 1 , and stores the write data within the data set in the fourth storage device 6 B 2 or sixth storage device 6 C 2.
