1. A network configuration restoration method in which configuration files of network devices are saved in an operation server in response to a save request and registered configuration files designated by a restoration request issued subsequently are reconfigured into the network devices to restore network configurations, whereinthe operation server comprising a storage means which saves configuration file of the network device by linking it to a first identifier and a second identifierthe first identifier represents a timing at which a configuration file is saved in the operation server in response to each save request,the second identifier represents an updating timing at which a configuration file identified as a configuration file saved in the operation server is newly saved in the operation server, andthe network configuration server performing the steps of:

  • identifying a network device which has an operation record in response to a current save request;

    acquiring a configuration file from the identified network device;

    judging updating of each identified network device by comparing the acquired configuration file and a registered configuration file linked to a first identifier representing the latest save timing;

    saving the configuration file acquired from the network device whose configuration file has been updated by linking it to a first identifier and a second identifier representing a current save timing; and

    copying a registered configuration file linked to the first identifier representing the latest save timing of a network device whose configuration file has not been updated, and linking it to a first identifier representing a current save timing and a second identifier linked to the registered configuration file and saving it;

    receiving a restoration request including a restoration timing;

    identifying a network device which has an operation record in response to the restoration request;

    acquiring a configuration file from the identified network device;

    judging updating of each identified network device by comparing the acquired configuration file and a registered configuration file linked to a first identifier representing the latest save timing;

    saving the configuration file acquired from the network device whose configuration file has been updated by linking it to a first identifier and a second identifier representing a current save timing;

    copying a registered configuration file linked to a first identifier representing the latest save timing of a network device whose configuration file has not been updated, and saving it by linking it to a first identifier representing a current save timing and a second identifier linked to the registered configuration file;

    reading out a second identifier of a registered configuration file linked to a first identifier representing the latest save timing;

    reading out a second identifier of the registered configuration file linked to the first identifier representing the restoration timing;

    identifying a network device to be restored based on the result of comparison between the second identifiers of each network device; and

    reconfiguring the registered configuration file linked to the first identifier representing the restoration timing into the identified network device.
