摘要

A method of managing local and remote data storage as a single logical volume, displaying to a user combined file names referencing both local data files and remote data files (Fig 3). The user individually selects file names and assigns a location attribute to the file names (307): residing only on the remote data storage, residing only the local data storage; residing on both the local data storage and the remote data storage. The location attribute of residing only on the remote data storage causes the local data file to be erased (313). The location attribute of residing only on the local data storage causes the remote data file to be erased (311). The location attribute, of residing on both the local data storage and the remote data storage, causes the files to be synchronized (309).
