Communication between application and kernel is a key problem in the design of virtual tape library(VTL) based on embedded technology.

A computer simulation technology for a variety of types of format integration solutions,which adopts virtual tape library data security protection,can guarantee object-oriented data storage system performance and to be more intelligent.

Based on Virtual Tape Library technology,this paper establishs teritary storage backup architecture which is used to improve backup performance of mass data.
