Study on disaster recovery model for information system
信息系统灾难恢复模型研究

A robust disaster recovery system model was presented to make information systems own continuous service talent even under disaster condition. The safe communication ability was strengthened to guarantee the secure command on disaster recovery. The self-supervision talent was introduced to watch the integrality and the security of disaster recovery system itself. Real-time visible platform was suggested to makes disaster recovery systems easier to use, manage and maintain. This model suits critical security environments such as e-government and bank. A key e-government disaster recovery system of China has been constructed guided by the model. It is verified that the network convergence and application response time can satisfy the system requests through the practice and matching simulation.
