			==Backing up the environment==
			* Attach the hdd you wish to back up and the hdd you wish to store the back up to to the machine.
			* Boot in an enviroment that leaves both hdds as read only (i.e. BCCD).
			* Locate where each hdd is in the /dev structure.
			* Mount both drives and ascertain the dircetory locations of both hdd takes special note of the one that is to be backed up.
			** example: mkdir ~/hda0; mount /dev/hda/part0 ~/hda0; ls ~/hda0
			* Umount both drives.
			** umount ~/hda0
			* Use the dd utility to perform the backup. Make sure the drive to be backed up is the input to dd and the drive to back up to is the output. If you want back up hda to hdc, the command would look like:
			** dd if=/dev/hda of=/dev/hdc
