Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention always monitors the possibility that various kinds of abnormalities may occur which cause the stop of the intranet or Internet server function of a device constituting a system in a computer or the destruction of programs and data. The present invention relates to a system for preserving a computer program and protecting stored data for quickly responding to a case where an abnormality is likely to occur and an actual occurrence of an abnormality and for restoring a normal state in a short time.

[0002]

2. Description of the Related Art In a conventional maintenance system of a server of an intranet or the Internet in a computer, when various values detected by sensors or circuits are out of a set range, that is, when an abnormality is detected. Automatically transfer the stored data and programs required for computer operation to another management device using a network, etc., and perform automatic restoration etc. using a recovery process command issued from the management device. Or simple recovery tasks can be automated, and advanced tasks that require complex operations can be supported by humans according to warnings displayed on the management device, or can be recovered by repair work according to the manual. And so on.

[0003] However, when a recovery method is artificially obtained by obtaining a recovery method from a management device via a communication means such as a network, if the network itself has a failure, it does not function at all. When providing personal support,
If a sufficient human support system was not in place, no response could be made at all, or even if it was possible, recovery would be significantly delayed. And
If the time until the start of human support is delayed, and if it takes time to respond, abnormal parts will multiply in the computer in proportion to the elapse of time, and the failure will progress without knowing,
It is often the case that data and programs are rewritten one after another in an abnormal state, making it more difficult to recover the original state.

[0004] Therefore, a system for responding to abnormalities as soon as possible and automatically restoring them has been provided for some abnormal matters such as, for example, a response to a power failure. However, since there has not been a comprehensive maintenance system that can respond to various types of abnormalities as a whole, computer programs and data are repaired in response to individual situations of the details of abnormalities.
In each case, the best response is not always the case.

[0005] For this reason, computer users have been relieved of anxiety about abnormal situations, for example, anxiety that business, stagnation of business activities, or suspension of product production lines due to destruction of programs and data may occur. Did not. And that was the biggest reason for reducing the reliability of computers.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and monitors the possibility of occurrence of various kinds of abnormalities on a computer intranet or Internet server. In order to quickly recover to a normal state, the system is built into the computer system as much as possible, and by further automating the work, an abnormal situation occurs in the computer system and programs that execute various computer processes. It also provides a reliable computer management system that can be reassured.
