  • System and method for network file system server replication using reverse path lookup
    Patent number: 9552367
    Abstract: The system and method described herein may use reverse path lookup to build mappings between file handles that represent network file system objects and full path names associated therewith and distinguish hard links between different file system objects having the same identifier with different parents or file names. The mappings and information distinguishing the hard links may then be cached to enable replicating changes to the file system. For example, a server may search the cached information using a file handle associated with a changed file system object to obtain the file name and full path name associated therewith. The server may then send the file name and full path name and metadata describing how the file system object was changed to a replica host, which may then replicate the change to the file system object.
