This paper designed mass buffer in network backup system(NBS),provided the definition,purpose,size assessment related to the backup cost,the design and implementation of mass buffer.Because of the delay caused by network transmission and process in remote backup center,the I/O rate in the local host is much faster than that of data backup,which caused the memory buffer queue will be more and more large.This problem was solved by the method of mass buffer,which was supported by secondary storage.The changes of data would be first put into mass buffer,from which the data then would be send to remote backup center.
