Patent ID: 8301597

Claim:
A system for replicating a network file system using reverse path lookup, comprising: a master file system; a master host having one or more processors configured to: receive a request to apply one or more changes to the master file system and a file handle that represents an object associated with the one or more changes to the master file system from a client computer; interpret the file handle to determine the object that the file handle represents, apply the one or more changes to the object within the master file system, and determine a full path name that the object has within the master file system based on a parent that the object has within the master file system; build a mapping between an inode number that identifies the object within the master file system and the full path name associated with the object; and transmit the mapping and metadata that describes the one or more changes to the master file system to a replica host configured to replicate the one or more changes using the mapping and the metadata.
