Overview
The HP EFS RCU is a command-line utility that runs on Windows 2000 or later. You
install the HP EFS RCU on a Windows client and server that communicate over a Wide
Area Network (WAN). The HP EFS RCU can be run through the Windows Services
Control Panel or the Command-Line Interface (CLI). You run the RCU commands
using the CLI.
The HP EFS RCU is designed to transfer data over a WAN link by minimizing the
number of round-trip handshakes and transferring only modified data blocks when it
executes consecutive copies of a set of files and directories. The HP EFS RCU
efficiently sends and copies data on high latency links when HP EFS WAN
Accelerators are deployed on the link. When a file or directory is copied using the HP
EFS RCU, Windows specific file features, such as security information (Access
Control Lists), NT file system streams, and file attributes are also copied.
