Abstract: PROBLEM TO BE SOLVED: To provide the simple backup and restoration methods by registering a system file and a shared file and monitoring the changes of these files. SOLUTION: An interface monitoring part 15 monitors the interface which changes the system file prepared by an OS 18. When the system file is changed, the contents of this change are sent to an extracted information management part 17 as the extracted information. A file monitoring part 16 monitors the change of a shared file. When the shared file is changed, the consents of this change are sent to the part 17 as the extracted information. The part 17 manages the extracted information which are received from both parts 15 and 16 and stores them in a storage 13 via the OS 18. If a request is received from a restoration processing part 19 for acquisition of the extracted information stored in the storage 13, these information are sent to the part 19 from the storage 13 via the OS 18.  Thus the information to be stored are limited only in a system component file, so that the time and the storage capacity can be saved compared with the conventional backup and restoration methods.
