This paper presents a method of building backup bit-table and restore bit-table in block level continuous data tolerance system,improves the efficiency of data restore by eliminating redundant I/O operations during its procedure.It is proved by experiments that block level continuous data tolerance system adopted on bit-table can quickly restore protected data volume to any point in time accurately.
