During backup and restore of file system,it needs to merge current backup resource tree and previous one,namely operations between catalog tree and resource tree.It designates backup resource while incremental backup.Users can use these strategies to backup fully or partially according to time point.A parsing algorithm of backup resource tree is given and it is analyized,based on the algorithm the formal description of backup resource tree is given.
