<p><P>PROBLEM TO BE SOLVED: To provide a remote copy storage apparatus system and a remote copying method which prevent a communication path from being overloaded and avoid the throughput of job processing in a center computer from being decreased. <P>SOLUTION: The center computer 10 performs a plurality of job processes, writes the result to a center storage apparatus 20, and remotely copies the same data to a plurality of remote storage apparatuses 30a, 30b. The center computer 10 acquires a load of communication paths 5, 6 via load measurement sections 14, 14a, 14b, 14c and stops the performance of part of the job processes associated with transmission of copy data via the communication path whose load exceeds a prescribed threshold value. When the center storage apparatus 20 and the remote storage apparatuses 30a, 30b switches the transmission paths of the copy data to other paths, the center computer 10 restarts remote copy by restarting performance of the job process having been stopped before. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
