Method of multi-computer back-up

Abstract

The present invention relates to a method of multi-machine backup. It is characterized by that any one main machine is connected with one or several stand-by machines, any one stand-by machine is connected with one or several main machines, in configuration file of every stand-by machine the IP address and backup cycle of main machine connected with said stand-by machine are recorded, and in the configuration file of every main machine the IP address or machine name of the stand-by machine connected with said main machine are recorded. Besides, said invention also provides the concrete steps of said method for implementing multi-machine backup.

Description

Technical field [0001] The present invention relates to a multi-machine backup method, in particular to a multi-machine backup in which one master machine can respond to backup requests of multiple backup machines, and one backup machine can also make backup requests to multiple master machines Methods. Background technique [0002] With the rapid development of network technology and the increasing scale of the network, the requirements for the reliability of the central server and other functional servers that store important data in the network are getting higher and higher. Stand-alone operation is far from meeting this requirement, so Important data servers must use the backup method of the main machine and the backup machine to back up the data. The current backup methods are both the main and standby modes of dual backup of the main machine and the backup machine, that is, one-to-one synchronization of the system and data files. The so-called dual-machine backup refers to ...

AI Technical Summary

Problems solved by technology

In order to ensure the real-time performance of the data, the master machine needs to detect the changes of the image file and the system in real time, so the performance of the master machine has a certain impact

At the same time, this method lacks identity recognition between the main machine and the standby machine, and cannot reject illegal backup requests, resulting in poor security

Moreover, systems that have high performance requirements for the master machine often do not have high requirements for real-time backup. However, in the existing dual-machine backup mode, in order to achieve real-time performance to the greatest extent, the master machine needs to detect changes in mirror files in real time. , has a great impact on the performance of the main machine, and cannot meet the requirements in an environment with high performance requirements for the main machine
