<p><P>PROBLEM TO BE SOLVED: To solve the problem that a conventional disaster recovery system is incapable of changing priority of transfer to a disaster recovery site according to contents of handled data. <P>SOLUTION: A computer at a DR site and a computer at a main site that constitute a DR system are so configured that even the computer at the DR site can grasp details of processing that the computer at the main site is performing so as to specify data which is not transferred to the computer at the DR site. Specifically, priority of a packet copy (or the packet itself) of a processing request is specified and transfer of the packet is controlled according to the specified priority. In this case, packets having higher priority may be transferred preferentially, for example, by transferring packets having priority as high as or higher than a threshold. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
