Continuous Data Protection(CDP) technology can choose backup the incremental data or original data as the continuous changed history data.This paper presents a Continuous Data Protection System(CDPS).It adopts backup the original data to storage device continuously.In order to achieve any point in time of rapid recovery,it also implements an optimized data recovery mechanism based on Bit-Table.Meanwhile it also gives two strategies to assure the availability of recovered data at utmost.It is proved by prototype experiments that the protected disk can be recovery to the right state quickly.
