摘　　要：随着数据信息越来越成为核心资源,网络信息系统的高可用性和容灾能力已成为焦点,如何构建远程容灾系统成为网络信息系统的关键之一.文章从容灾的基本原理入手、阐述了容灾系统的类型及主要性能指标,分析了容灾的关键技术及选用原则,最后给出了一种基于Internet的异地容灾系统实现方案.该方案采用两层容灾结构:网络服务系统容灾和网络存储系统容灾.With the trend that data information has become the most important resource, the high availability and disaster tolerance of Network Information System become a pressing need. How to construct remote disaster tolerant system is an important problem in the network information system area. First, the paper introduces the basic concept of disaster tolerant, the categories and main performance indicator of disaster tolerant system, then analyses its key technology and selective principle. Finally, a remote disaster tolerant system based on Internet has been presented, which adopts two levels disaster-tolerant system structure： network service system disaster tolerant and network storage system disaster tolerant.
