The Method of Multi-Point Data Backup in Disaster Recovery Systems
Zhong Hui-hui, Wang Zheng-Xia · 2012
A multi-point data backup method for disaster recovery systems is proposed in this paper. It can effectively increase the data redundancy and improve the system reliability by backing up the data to multiple copies stored in different places. In this method, first, the local production server backs up data to the primary backup server which is selected by the server's load, and then the other backup servers will back up the data from the primary server regularly .In this way, it not only improved the stability of the system, but also reduced the impact on the local server performance greatly.
