Backup Linux /home to an external USB HD

I have Xandros debian 3 base OS, which has 1 4G /home device.
I like to backup /home to an external USB 80G HD. What is the easy way on doing it. Also my XP machine has the DVD RW drive, could I use that to backup my Linux /home FS. I am thinking to buy NeroLinux or a retail Nero.
The retail Nero allows me to get a free LinuxNero download.

Thanks for the comments :doh:

mount the USB Disk and tar the /home Directory to it.

tar -cvzf /where/is/the/usbdisk/home.tgz /home

But this has nothing to do with nero at all :wink:
