摘　　要：随着IT系统的广泛深入应用,IT系统的高可用性和容灾能力问题日益成为一个关注的焦点,容灾系统的建设对于国防、政府、企业都有着重要的意义。容灾系统的目标在于提高IT系统的生存能力,保障业务流程的连续性,减少因各种灾难而造成的损失。 该文依照工程化的思想,以容灾系统生命周期模型为基础,提出了容灾系统的需求分析和设计方法,并对主要的容灾技术进行了比较分析。As IT system becomes a key component of business process, its high availability and disaster tolerance become a pressing need. Disaster tolerance system has significance to national defense, administrations, enterprise. The main aim of disaster tolerance system is to exalt system survivability, to keep business continuity and to reduce lost. According to engineering idea, a living cycle model is introduced. Based on this model, a new method for disaster tolerance system analysis and design is proposed and discussed. At last main disaster tolerance technologies are compared.
