System backup and recovery method, and backpu and recovery server

Abstract

The invention discloses a system backup method with ID checking. The backup server judges whether the MAC address of backup aim board of sending the backup request is legal or not; if yes, then responding the request; otherwise, rejecting the request. This invention offers also a system restoration method as well as a backup and restoration server related to the above two methods. Using MAC address in multi-host backup to verify ID of backup aim board exerts advantages of hi-reliability of multi backup as well as realizes the ID checking in multi backup system based on the aid of the uniqueness of the MAC address.

Description

technical field [0001] The present invention relates to data processing technology in the communication field, and more specifically, relates to a system backup and recovery method and a backup and recovery server. Background technique [0002] The rapid development of network technology and new computer architecture has put forward higher requirements for the reliability of the central server and other types of servers that carry important data in the network. Stand-alone operation is no longer competent, and important data servers must be equipped with backup and recovery. Program. Currently, the most widely used system backup and recovery method is active-standby dual-machine backup. When this method is used, during the system operation, the two machines maintain the synchronization of the system and data through the communication cable. The current working machine is the master machine, and the other machine The station is a standby machine, and the standby machine cont...

AI Technical Summary

Problems solved by technology

However, due to various reasons, the IP addresses of the active and standby machines in many current systems often change during operation, especially when using such as DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) protocol to dynamically obtain the IP address , this method of authentication is even less feasible

In addition, when the system crashes, the operating system cannot be started, and the server cannot obtain the IP address of the host computer that needs to recover the system, which further limits the scope of application of this IP address-based authentication method.

[0004] It can be seen from the above description that due to the low reliability of the dual-machine backup method in the prior art, the authentication based on the IP address of the multi-machine backup method cannot be applied to the scheme of dynamically obtaining the IP address, nor can it be used when the system crashes. Therefore, the above two solutions cannot effectively solve the problems of low reliability and inability to perform identity verification during the system backup process.
