摘　　要：本文以某市"金保工程"为例,在分析SAN架构的基础上,设计了基于SAN架构的存储系统和软件架构模型,对目前主要采用的数据备份策略:完全备份、增量备份、差量备份的实质及特点进行了细致的分析,并在此基础上提出一种改进的备份策略:基于事务日志的差异备份方法,弥补了传统的备份体系中存在的漏洞,提高了备份速度。Differential backup was set up on the basement of ＂golden insurance project＂ in this paper. Storage sys- tem and software framework model of SAN was designed based on the analysis of SAN. The essence and characteris- tics of backup strategy are analyzed carefully, which including full backup, incremental backup and differential backup. An improved backup strategy was proposed that log-based differential backup methods which making up the vulnerabilities of traditional backup system contained and improving the speed of the backup.
