摘　　要：根据某电子政务试点示范工程对业务可持续性的具体要求,论文提出一种灾难恢复系统模型。模型强化了通信保障能力,提供安全可靠的灾难恢复控制；创新地提出自我监测能力,实现对灾难恢复系统自身的完整性和安全性监测；使用GIS、GPS、RS技术使灾难恢复系统更易于使用、管理和维护。模型具有突出的安全性、健壮性和可管理性,适用于电子政务、银行等安全级别较高的环境。在RDRSM的指导下,某电子政务灾难恢复系统已经建设完毕并运行了一年。实践尤其验证了模型中灾难恢复计划、系统监测、通信保障的重要性。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.
