  In the backup and restore method for system setting information in the conventional software, the system setting information collected in the previous version is applied to the new version of the software. The version of the software needed to be compatible to read the configuration format of the previous version of the software. Therefore, when the contents and format of setting items are expanded by version due to updates such as patches, the new software maintains compatibility for understanding setting items of all previous or many versions of the format. There was a need to do.

  On the other hand, as a problem that exists at the time of restoration, for example, when returning to the previous version by reinstallation due to a hardware failure or the like, it is necessary to update the software system to a newer version than when collecting backup data in advance. In other words, when backup data is collected in a newer version than the software system configuration at the time of restoration, it is necessary to change the software system to a newer version than that at the time of collecting backup data before executing the restore. This is because the previous version of the software system may not support the setting format in the new version.

  In particular, when the entire system including not only hardware but also software is provided to companies, etc., when a system failure occurs in each company that provides the system, it is not possible to restore the system with awareness of the version. Not only was it bothersome, it was also the cause of mistakes.

  Therefore, the present invention provides a restore system and a restore method that allow a restorer to restore software at the time of backup together with data handled by the software without being aware of the software version. The purpose is to provide.

  According to the present invention, the package configuration list describing the package configuration of the software that has been operating the data together with the data is saved as backup data, and the data is restored when it is necessary to restore the data. In addition, there is provided a restore system that restores the software according to the contents described in the package configuration list.

  In the above restore system, if the package configuration list describing the current package configuration is compared with the restored package configuration list, and the two are different, the contents described in the restored package configuration list Thus, the software may be restored.

  In the above restore system, the package configuration list describing the current package configuration is stored in duplicate, and any package configuration list describing the current package configuration is compared with the restored package configuration list. You may do it.

  In the above restore system, software to be restored may be downloaded via a network.

  In the above restore system, the software to be restored may be stored in front of the network, and may be input without going through the network when restoring.

  As a part of system setting information or part of the system setting information backup data, record the configuration information including the version number of the software system at the time of collecting the current or backup, and then back up the system setting When restoring information, even if there is incompatibility of setting information between software versions, the necessary software configuration can be restored at the same time, and operation can be resumed in a system corresponding to the backed up setting information.
