摘　　要：为了在数据出现丢失或系统崩溃时,迅速地恢复系统和数据,文中提出一种基于卷的持续数据保护(continuous data protection,CDP)备份方案.该方案首先对CDP技术进行研究,归纳总结CDP技术的特点;其次,结合卷级备份算法,分析卷级CDP备份原理;最后,依据CDP技术和卷级备份原理,构建卷级CDP备份方案模型.研究结果表明:文中提出的卷级CDP备份方案可以提供粒度无限的恢复点,通过挂载的方式即可查看和使用任意时间点的数据.The research on the backup solution based on continuous data protection established a volume level backup model for CDP continuous data protection.Firstly,the plan researched the CDP technology and summed up characteristics of CDP technology.Secondly,the plan combined with the volume level backup algorithm and made a conclusion on the the principle of CDP backup technology.Finally,according to CDP technology and the principle of volume level backup,we built up the CDP backup plan model.The study indicated that the volume level CDP backup plan proposed in the paper can provide unlimited recovery point （RPO）,view and use the da-ta at any time point by the way of mounting.
