Abstract. Data storage security issues are expanding to global area, while -Internet+‖ Smart Energy is prospering in high speed. Therefore, the security backup for the distributed file system (DFS) has become the key factor in the construction of smart grid in electric power. However, due to remote data synchronization across multiple data centers, the reliability and robustness of the storage system is relatively weak. Our work proposed a novel active-active disaster recovery model, with a Virtual Redirection Network (VRN). Under the automatic control of VRN, the model provides a solution of data synchronization across large scope of power grid center. The results show that the system not only improves the IO performance in massive small files, but also increases the total system robustness over a long distance data transfer.
