| Abstract: | 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. |
