- The need for saving a great many files becomes necessary in distributed file system environment. Particularly, some file systems maintain multiple file replicas for efficient failure recovery. Under these circumstances, however, all the file replicas have to be modified identically to update a file. If there are many clients to update the same file concurrently, the final images of all replicas can be inconsistent. In this paper, we propose a consistent update method so that a file can have the identical image in all replicas after concurrent modifications by multiple clients.
