Focused on the existing file system in the fault-tolerance and reliability are much lower than the database system,this paper uses the principle of data multiple versions technology in database system to achieve quickly flashback and non-blocking read.By improving the meta-data structure of file system and the combination of copy-on-write techniques,this paper solves the problem of existing file system lack of fault tolerance and enhances the read performance of file system.MVFS is made by the method.Experimental results on MVFS show that the method applied to generate the file system posses excellent read performance,fault tolerance and reliability
