Well i don't know any ISO that says how to, say, clean your teeth either,
but everybody
tends to do in a couple of ways. 

It's a de facto convention to clean your teeth from up to down, and experts
says this is
the best way to do it, far better than right to left.

Just kidding ;-) ;-) ;-)

Now, seriously, i don't have access to ISO/IEC 17799 standard but i think
that's the applicable
(i don't know if delta backup is defined there).

Yep, this is a great program :-)
I'm enjoying myself tweaking bumpXXXXXX parameters in amanda.conf.
Thank you very much list, you are great :-)

Now for something completely different ( ;-) )

The chg-zd-mtx changer script knows about barcodes, but,
What's the difference between using it or don't?
Just time looking for the next tape on the changer?, or it will refuse/warn
to load
a non/bad barcoded tape?

Thank you very much
