摘要
分析了数据库物理备份与逻辑备份、静态备份与动态备份的相关特性及影响数据库容灾性能的几个关键因素。重点对基于OS(operation system)及存储的数据库容灾技术进行研究,并以结构图的方式显示了每种容灾技术的工作原理、特点及应用,该研究成果可为后续数据库容灾技术的理论研究与实践发展提供参考价值。
The related characteristics of database backup, including the physical backup, the logical backup, the static backup and the dynamic backup, were firstly analyzed in this paper. Besides, key factors of database disaster tolerance were reviewed from the viewpoint of database backup. Then, this paper mainly discussed database disaster tolerance technology based on OS（operation system） and storage, and illustrated the working principal, structural features and specific applications through structural diagrams. Research results provide useful reference for the theory and practice of the database disaster tolerance technology.
