Study on Disaster Recovery System Model
灾难恢复系统模型研究

According to the requests of continuous service capability of a certain E-government Experimental and Demonstration Project of china, the paper presents a new Robust Disaster Recovery System Model. RDRSM strengthens the ability of safe communication and guarantees the secure command on disaster recovery. Its self-supervision capability can monitor the integrality and security of disaster recovery system itself. Using real-time visible platform provided by GIS, GPS and RS, the model can make disaster recovery system easier to use, manage and maintain. The model possesses features of security, robustness, controllability, and can be applied to highly security-critical environments such as e-government and bank. Conducted by RDRSM, an e-government disaster recovery system has been constructed over one year. Practice verifies the significance of some components in the model, such as disaster recovery planning, system supervision, communication support.
