一种针对SAN构架企业的异地数据容灾系统设计方法

设计了一种针对SAN构架企业的异地数据容灾系统。该系统针对SAN构架的特性，将企业数据按特征划分为静态数据和动态数据。基于电子链接的方法论标准进行企业异地数据容灾系统的设计，通过虚拟磁带库的备份、传输及恢复，结合更改流程控制方法实现静态数据的异地容灾；通过对标准异步数据复制方式创新改进，实现动态数据的异地容灾，同时提高了复制效率，降低了链路最高带宽要求。更好的体现了系统的可靠性与经济性。

Design of Data Disaster Tolerance System Based on SAN Infrastructure

A remote data disaster tolerance system based on enterprise IT SAN infrastructure is presented.According to the characteristics of SAN infrastructure,enterprise data were classified into static data and dynamic data.This system was designed based on the electronic vaulting theory.The paper presents the remote disaster tolerance of static data by using virtual tape library to run data backup,transfer and restore,combining with the method of changing process control,and it presents the remote disaster tolerance of dynamic data by innovating and improving current standard data asynchronous replicating method.The results show that it improves the replicating efficiency,reduces the MAX bandwidth of data link.and represents the reliability and cost-saving capability of the system.
