How to Backup Debian with Backupninja - home user

The home user how to make backups as easy as:
#backupninja -n

*Overview

Backups the never ending problem. Follow this How-To if you have:

a) a cd/dvd burner, (to use backupninja's makecd) OR
b) two linux pc's on a LAN, (to use backupninja's rdiff) OR
c) want an example of backupninja you can adapt to use:
-- a spare hard drive be it internal or usb (you can rdiff to a local directory/partition)
-- push backups over the net to another pc/server (that you have permissions to ssh into) (rdiff if trusted or duplicity to encrypt the data)

We will install, setup and use backupninja to create backups over a LAN and/or create iso images you can burn to cd/dvd using your favourite burning program.

Note: If mixing i386/amd64 and etch/sarge then see this post

*Information

There is very good documentation at backupninja and a guide to usage at debianhelp.co.uk (thanks to david23 for the link) and of course:
$man backupninja
$man ninjahelper

This excellent documentation and the way backupninja integrates backup into the sytem while providing multiple ways to backup at the same time are all good reasons to use it.
This How-To will not attempt to cover all that is available in the above, rather it aims to set up a easy backup system using cd/dvd and/or another pc on a home LAN.
