I use rsync to make a daily back up of my data on a second drive that is 
not normally mounted except when the backup is running.  The drive is 
inside the same box so this backup is still subject to loss if the box 
is stolen or destroyed.  I really should be backing up to an off site 

If you have a fire, flood, or other general disaster your local backup 
on an external drive isn't going to buy you anything unless you store 
the external drive off site.
