| 摘 要： | 通过分析传统容灾方案的不足,提出并实现了一种基于文件级的持续数据保护(CDP)系统.根据CDP三个属性,通过文件过滤驱动实时的跟踪和截获对文件的修改操作,并且对截获的内容以逆操作的形式记录到日志文件中,存放在非本地的存储设备里.当灾难发生时,可以根据日志文件快速恢复到过去的任意时间点,实现数据的恢复.

| Abstract: | The disadvantages of traditional projects of disaster recovery was analyzed,then one system of file-based Continuous Data Protection(CDP) was proposed and implemented.This system continuously captures or tracks data modifications of files and stores inverse operations of changes in log files independent of the primary data base on three fundamental attributes of CDP.When some disasters happen,CDP can offer fast data retrieval to any point in time according to log file to realize date recovery. |
