Multi-point multi-level data real time backup method

Abstract

The invention provides a multi-point-multi-jump real-time data backup method. The method makes a real-time backup of table-level data between a master database server and a multi-target backup database server by the technologies of data real-time monitoring, data multi-point-multi-jump transmission and data remote redoing, wherein the multi-point refers to a plurality of database backup points between the databases of the same level (the same LAN), wherein the multi-jump refers to a plurality of database backup points between the databases of different levels (different LAN). The invention enables backup granularity to a table level and supports a plurality of backup points, which adopts the mechanism of data encryption and error control, thus ensuring the data transmission security. The invention has advantages of good real-time, high efficiency, convenient operability and broad application prospect.

Description

1. Technical field [0001] The invention provides a multi-point and multi-hop data real-time backup method, which belongs to the field of information security. 2. Background technology [0002] As disaster backup and recovery become a topic of increasing concern in the field of information security, disaster recovery systems are widely used in important industries such as finance, banking, and civil aviation, among which real-time data backup is a key technology to ensure the security of sensitive data. [0003] Commercial database management systems provide some database backup and recovery tools. However, these methods for real-time backup of table data have the following disadvantages: [0004] (1) Poor real-time performance and slow data update; [0005] (2) Cannot support multiple backup points at the same time; [0006] (3) Real-time backup of the entire database, the amount of backup data is large, and the requirements for the resource allocation environment are rel...

AI Technical Summary

Problems solved by technology

[0004] (1) Poor real-time performance and slow data update;

[0005] (2) Cannot support multiple backup points at the same time;

[0007] (4) Poor fault tolerance, when the network fails, it needs to be backed up again

[0008] The patent publication number is a data backup system described in CN1851662, which cannot realize multi-point multi-hop data real-time backup
