a quick and easy backup program

[Jude DaShiell]

Actually there's another problem with 'cp -a /'.  Three directory trees 
get copied that are not supposed to get copied onto other machines since 
other machines are supposed to make those trees for themselves.  The 
/proc; /pts, and /dev trees need to be excluded.  That can be done with 
the right tar command, or there's another package called dar which can do 
this but haven't got its url now.  I did read a tutorial on it on the 
internet though.
