摘要
传统的数据容灾技术由于存在种种的缺陷,不能满足用户对数据实时性保护的需求。文章研究了新型的持续数据保护技术(CDP),并设计和实现了文件的CDP系统。实验表明,系统能实现文件的粒度细保护,使文件能回退到文件之前的任意状态。
Due to the various defects,the technology of traditional data disaster recovery can not meet the needs of continuous data protection.Continuous data protection（CDP） technology as the latest technology is analyzed,the file protection system on CDP is designed and implemented.The experiments show that the system can protect files perfectly and files can be recoverted completely.
