making a backup of my linux filesystem with tar and bz2

[Nick Gawronski]

Hi, so what command would I run from the mount point where my USB drive was 
mounted to only backup the local ext3 filesystem using tar so the contents 
of the USB drive would not be included in my backup and when I wanted to 
restore it I would be in the directory where the USB drive was mounted and 
would mount my system on another mount point what would I type to do the 
restoration?
