Abstract
In a data center, when a server is disconnected from the Internet because of illegal manipulation of a file, valid files (not manipulated) are copied to a standby server and the processing is resumed after a short period of disconnection. According to the invention, a control program Pperforms manipulation checks for all files listed in a manipulation checklist. If any of them is manipulated, it issues a request to disconnect from the external network and a request to assign a standby server to a control program Pof a management server. Upon receipt of a disconnection completion signal and the address of a standby server b, the control program Pcopies valid files (not manipulated) to the standby server b, and for invalid files, requests the copies of their backup files. After finishing copying, the management server connects the standby server bto the external network to resume processing.
