properly. First thing you need is an extra drive that is bigger than the
one you are cloning. Get your hands on a liveCD of ubuntu, any flavor will
do. Make sure two disk utilities are available, gparted and disk utility.
Gparted will allow you to easily format a disk. Disk utility will allow you
to do the same but is not as visually friendly as gparted.

In your liveCD make sure both disks, your primary one and the backup disks
are mounted. Create a folder in the second drive which will be used to
store the image.

Read this documentation on how to use "dd".

If you have two drives installed in your system, they will have these
names, /dev/sda and /dev/sdb. If they have partitions they will be
/dev/sda1 or /dev/sdb1 with one meaning partition one. What you will be
using is cloning /dev/sda to the folder residing in your second hard drive.
