Application of Remote Mirror based Data Level Disaster Recovery Technologies to Zhejiang Electric Power Company

To improve the risk-resisting ability of enterprise information systems and reduce the loss risk of important data, there is a very urgent need for Zhejiang electric power company to construct a safe and reliable data-level disaster recovery center. On the basis of in-depth analysis of existing disaster recovery technologies, for the Zhejiang electric power marketing business application system example, this paper takes its situations into consideration and successfully constructs its corresponding disaster recovery system using the remote mirror technology. The system achieves data level disaster recovery goals with no data loss and no delay. Practical experience will be helpful for further construction works of the global disaster recovery system.
