This paper analyzes the problems in the current block-level Continuous Data Protection(CDP),a CDP mechanism based on increment backup server is proposed.On the basis of TRAP-4,this paper improves the generation mode of log chain and compression methods of related data,validates the correctness of the log link periodically.The main work of continuous data protection is migrated to the increment backup server,then the workload of server system is alleviated effectively.Experimental results prove the validity of the mechanism.
