Abstract


The increasing number of threats to data security , data failure caused the loss is immeasurable . Although this data recovery technology has been more research , but with the urgent need for data security , and data recovery technology inherent limitations in recent years to improve the data recoverability related research widely expand accelerate the development of data recovery technology . Mirroring technology as a solution to the disaster caused by data insecurity has been widely used , continuous data protection technology as improve data recoverability way after a period of silence , gradually been adopted research being . However , a single data recovery technology limited role . Based on this situation, in -depth analysis on the basis of continuous data protection technology , there are several issues , integration of mirroring technology , the insecurity faced by current data storage of a data protection program TH - CDPS , the program design , a prototype system . TH-CDPS build based mirroring technology and continuous data protection technology applicable to data security with different RTO (Recovery Time Objective) and RPO (Recovery Point Objective) requirements of the enterprise or personal . Program unique organizational structure of the metadata , to solve the existing continuous data protection technology to restore data and delete data selection , and made ??a variety of means of performance improvement , including: \\after the same time the different data state) concept. Finally, the test of the the TH-CDPS current version , verify the correctness of the program and the effectiveness of a variety of technical means .
