基于CDP的数据容灾系统设计与实现

Implement of data disaster-tolerant system based on CDP

数据容灾系统是保障核心业务系统安全、稳定、持续地运行,增强抵御灾难和防范系统故障的关键.文章运用CDP技术,针对恢复点目标和恢复时间目标要求,构建一个具有持续数据保护功能和全面数据恢复能力的本地/异地的双重数据容灾系统.实践表明,该数据容灾系统实现了高性能的本地和异地数据容灾,同时系统将数据存储与容灾结合在一起,具有很好的实用性.

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.
