File synchronization of multi-machine system design and implementation based cloud storage

With the popularization of computers and social development, it is become more and more common the personal remote office and electronic office. The question is becoming that how to synchronization of large amounts of files between multiple computers. In this paper, the mechanisms of metadata is used to directory synchronization and control file version. According one of the properties of the cloud storage which can store additional and to improving the efficiency of large file transfers, file segmentation is used. To achieve synchronization between multiple computers, we used cloud storage to save and transit through the file.
