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, which has a certain impact on the performance of the master machine
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

Embodiment Construction
[0026] The inventive idea of the present invention is in order to realize the many-to-many backup between a plurality of master machines and a plurality of backup machines, the master machine is more than one, and the backup machine is also more than one, and any master machine can be connected with One or more or all standby machines are connected, and any standby machine can be connected with one or more or all main machines.
[0027] Each main machine has a main machine processing module and an application management module, the standby machine has a standby machine processing module, and the main machine processing module has legal standby machine configuration and management, standby machine connection request authentication, standby machine connection request response and Standby machine backup request response function. The configuration file of the master machine records the IP address or machine name of the backup machine connected to it; the application management ...

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 invention relates to a method for multi-machine backup, in particular to a multi-machine backup in which one main machine can respond to backup requests from multiple standby machines, and one standby machine can also send backup requests to multiple main 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 storing 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 mode of the main machine and the standby machine to back up the data. The current backup methods are the main backup mode of dual-machine backup of the active machine and the standby machine, that is, one-to-one synchronization of the system and data files. The so-called dual-machine backup refers to ...
