Disaster-tolerant system is the key for stable running of application system and preventing system fail- ure. This paper describes how to apply the CDP technology to building the local/remote data disaster-tolerant system with continuous data protection and overall data recovery. The practical application shows that the system combines the data storage and disaster-tolerance and has high performance of local/remote data disaster-toler- ance.
