摘要
随着信息应用技术的发展,越来越多的信息系统投入使用,容灾备份技术作为系统高可用性的首要保障从未停止过研究,适合于不同场景的容灾备份解决方案日新月异。本文针对大型信息系统多地区分散部署、硬件设施不同和软件结构复杂的特点,提出一种多点多备的容灾备份系统方案使信息系统的每一个部署节点具备一对多和多对一的灾备能力,部署节点之间互为备份,最终实现多个节点的数据同时备份,每个备份数据都有多个异地备份副本的高可靠数据容灾。本文深入研究了实现多点多备的数据远程复制技术、数据备份方式和数据同步协议,提出了相应的实现方案和具体的同步协议。
With the development of information technology, more and more information system put into use.The study of the disaster recovery technology, as the primary guarantee of high availability system, never stopped,thus the disaster backup system can be applied to different scenarios. Based on large information system has characteristics of the more decentralized deployment, different hardware and complex software structure, puts forward a disaster recovery system solution of multi-point and multi-backup, which enable each deployed node have a one-to-multi, and multito-one disaster recovery ability and among deployed nodes are backup to each other, Finally realize backup multiple nodes and at the same time have multiple different backup copies each backup. This paper studied how to implement multi-point and multi-backup deeply, including the data remote replication technology, the way of data backup and the data synchronization protocol, also proposes the corresponding implementation scheme and the concrete synchronization protocol.
