The process of identifying the progress of the clones from the machine more easily and reduces the load on administrators, network network device on the data transfer is to be improved , including managers, and managing these systems, and a method for performing a process on the network devices connected to a network clone is proposed . A network device according to the present invention is a clone (clone) the data and the network manager storage unit for storing the location information , and perform a clone clone process on the basis of data , corresponding to the process-state clone of the clone process report progress control unit for generating data and , clone process status report generated by the network administrator for the data and a transmitter configured to transmit location information to the network administrator.
