摘要： Overload of communication lines and the drop of through-put of task processing in a center computer is prevented. The center computer executes a plurality of task processing, writes the execution result to a center storage device and remote copies the same data to a plurality of remote storage devices. At this time, the center computer acquires loads of communication lines through load measurement portions and stops the execution of a part of the task processing involved with the transmission of the copy data through the communication line when its load exceeds a predetermined threshold value. When the center storage device and the remote storage devices switch the transmission route of the copy data to other route, the center computer starts again the execution of the task processing previously stopped and starts again the remote copy.

摘要： A plurality of second groups respectively including one or more second volumes are configured in correspondence with each of the first groups of a remote copy source in a remote copy destination, journals are acquired from the first storage apparatus periodically and in the order the journals were created for each of the configured second groups, and the acquired journals are reflected in the corresponding second volume in the corresponding second group. In addition, the latest time stamp of each of the second groups containing the journals retained in the second volume in an unreflected state is compared, the time difference of the latest and oldest time stamps is detected, and prescribed control processing is executed for acquiring the journals regarding the second group with the oldest time stamp in preference to the journals regarding other second groups when the time difference exceeds a preset threshold value.
