File synchronization method and system based on dual redundant system and storage medium

Abstract

The invention discloses a file synchronization method and system based on a dual redundant system and a storage medium, and the method comprises the steps that standby equipment loads first preset information of a first transmission file to a request data packet, and then transmits the request data packet to main equipment; the main equipment receives a request data packet of the first transmission file sent by the standby device, and extracts first preset information in the request data packet; the main equipment compares the first preset information with second preset information of a secondtransmission file in the main equipment, and judges whether the first preset information is the same as the second preset information or not; and when the first preset information is different from the second preset information, the main equipment sends a first response data packet to the standby device, and the main equipment synchronously transmits the second transmission file to the standby device. According to the file synchronization method and device, only different transmission files in the main equipment and the standby equipment are synchronized, the overall efficiency of file synchronization is improved, and therefore the standby equipment and the main equipment operate in a coordinated mode.

Description

technical field [0001] The invention relates to the technical field of high-availability system design, in particular to a file synchronization method, system and storage medium based on a dual-machine redundant system. Background technique [0002] Telecommunications equipment requires extremely high availability of business services. When developing and designing, it is necessary to take into account that functional modules such as the operating system, drivers, and hardware resources of the equipment can quickly restore normal business services. Therefore, the industry has widely used two relatively An independent device system provides a set of business service functions. One of the device systems is in an active state and provides business services, which is called the master device; the other device system is in an inactive state and does not provide business services. It is called it for spare equipment. When the primary device fails, it can quickly switch to the bac...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to provide a file synchronization method, system and storage medium based on a dual-machine redundant system, aiming to solve the problem that the primary device and the backup device do not synchronize files for the same file in the prior art. Necessary transfers greatly reduce the overall efficiency of file synchronization
