摘要：
A first storage subsystem includes a first storage device and a second storage device(s). A second storage subsystem includes a third storage device and a fourth storage device. A third storage subsystem comprises a fifth storage device and a sixth storage device. The first storage subsystem generates a dataset comprising an update number expressing the update order of the first storage device and write data stored in the first storage device, stores the generated dataset in the one or more second storage devices, and transmits the data set to the second and third storage subsystems. Each of the second and third storage subsystems stores the received dataset in the third storage device or fifth storage device, reads a dataset from the third or fifth storage device according to the update number, and stores the write data within the dataset in the fourth storage device or sixth storage device.
