Overview

The HP EFS RCU is a command-line utility that runs on Windows 2000 or later operating systems. 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 HP EFS 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. The HP EFS RCU can significantly accelerate the performance of more comprehensive backup products by allowing the shrinkage of backup windows and enhanced backup architectures. 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.
