摘 要：To remedy the defect of data storage possible overflow to lead the latest data loss in the data storage system,this paper proposed a method using data rewind mechanism to store data to solve data storage possible overflow problem.The result indicate that the discrete data storage area is turned into end to end of the closed loop Using data rewind mechanism,to realize a data storage does not overflow.In view of data rewind lead to the problem of incomplete data,the paper put forward the method of the backward analysis,by comparing the adjacent data storage space whether there is the intersection to determine the complete data,incomplete data is discarded.
