摘要
随着网络技术的发展,数字图书馆起着越来越重要的作用,但其容灾措施未引起重视。文章首先描述了容灾的概念和原理,然后设计了一种基于复制技术的容灾系统,给出了详细的算法。该容灾系统通过增加服务器的远程备份节点以增强系统的可用性。
Digital library is playing an important role with the development of network. People don＇t attach importance to the method of disaster recovery about digital library. This paper firstly discribes concept and principle of the disater recovery, then designs a disaster recovery system for digital library based on replication, and presents detailed algorithms. In which the system usability can be strengthened by constructing replication of server.
