System, method and apparatus used for safety information data disaster recovery backup

Abstract

The invention provides a system used for disaster recovery backup of safety information data, a method used for the disaster recovery backup of the safety information data, and an apparatus used for the disaster recovery backup of the safety information data. The system used for the disaster recovery backup of the safety information data includes a main data processing server, a shared data server and a backup data processing server; the backup data processing server keeps real-time synchronization between a backup safety information data table and a safety information data table in the main data processing server; and when a fault occurs on the main data processing server, the backup data processing server acquires a required backup file generation condition table and / or a primary key file from the shared data server based on configuration information from a user so as to execute disaster recovery backup operation and works for a new main data processing server later. The system, method and apparatus used for the disaster recovery backup of the safety information data of the invention are advantageous in high safety, high reliability and easiness in expansion.

Description

technical field [0001] The present invention relates to a system, method and device for disaster recovery and backup, and more particularly, to a system, method and device for disaster recovery and backup of security information data. Background technique [0002] At present, with the increasingly widespread application of electronic computers and network communications and the increasing variety of business types in different fields, it is used for security information data (that is, important information data that requires high security and reliability, such as financial systems) A system, method and device for disaster recovery backup of transaction data in . [0003] The basic working principle of the existing systems and methods for disaster recovery and backup of security information data is as follows: at periodic points in time (for example, multiple sessions per day) based on the file generation condition table, each security information data record Generate corres...

AI Technical Summary

Problems solved by technology

[0004] However, the existing systems and methods for disaster recovery and backup of security information data have the following problems: In order to achieve zero data loss in remote real-time synchronization, high software and hardware costs are required, and once the files are generated If there is a second-level error in the synchronization process of the conditional table (that is, the main data processing server fails), it will cause a large number of errors in the file generation process
