Abstract: Transmitting filesystem changes over a network is disclosed. A hash of data comprising a chunk of directory elements comprising one or more consecutive directory elements in a set of elements sorted in a canonical order is computed at a client system. One or more directory elements comprising the chunk are sent to a remote server in the event it is determined based at least in part on the computed hash that corresponding directory elements as stored on the remote server are not identical to the directory elements comprising the chunk as stored on the client system.
