[Debian Home Server Series] 8. Backup Server - rsync

Introduction
Occasionally, client machines like notebook or desktop may need to bereinstalled from scratch. The recovery of OS and different kinds ofapplication software is time-consuming, but usually risk-free. The mostimportant and challenging task is to recover user data with the mostup-to-date version. This is when the backup system comes in.

For a home-user environment, I have picked a simple tool - rsync. It has the following advantages:

* provides fast incremental file transfer
* easy to setup
* open source under GPL
