[lug] Tape backup error

[Bob Collins]

Thank you Hugh.  

That works just as you said it would and it will work just fine for what
I am trying to do.  I have used the taper backup application before, it
is base on tar.  That is why I was trying to figure out how to make it
work with tar.  The taper application comes with linux.

Thanks again.

Bob
