摘要： A disk subsystem assures the sequence and the coherence of data updating with two or more disk subsystems is provided with an asynchronous remote copy function. A main center 9 includes a computer system having the configuration of slave subsystems 3-2 to 3-n connected with a master disk subsystem 3-1. It secures the coherence between data at the main center 9 and the remote center 10 at the temporary suspension by repeating temporary suspension and release of the temporary suspension of the remote copy by the master subsystem 3-1 at predetermined opportunities. It also repeats temporary suspension and release of the temporary suspension of the remote copy by slave subsystems 3-2 to 3-n connected to it.

摘要： An asynchronous remote copy system is provided which can ensure the data renewal order and data integrity of the disk subsystems and are easy to be incorporated and free from degradation of the process performance of host computers. To this end, in the remote copy system for data mirroring, a main center has one gateway subsystem and a remote center has one gateway subsystem, and disk subsystems in each center to be remotely copied are connected to the corresponding gateway subsystem. Data is mirrored through synchronous type remote copy between a volume of the disk subsystem of each center to be remotely copied and a desired volume of the corresponding gateway subsystem, and the gateway subsystem of the main center sends the renewal data to the gateway subsystem of the remote center in accordance with the order of renewal of volumes of the gate way subsystem of the main center, to make the gateway subsystem of the remote center reflect the renewal data upon the volumes thereof through asynchronous type remote copy.
