just trying to protect the tapes ( backups ) against the casual
"oops look what i found"  and they go and look at the HR records
or the  salary records or employee reviews etc..etc..

not trying to protect the tapes against the [cr/h]ackers ( different
ball game )  and even not protecting against the spies of nsa/kgb etc
either  ( whole new ballgame for those types of backup issues )

dont forget to lock the car/safe too :-)
and log who goes in and out of the "safe" area :-)

not my first choice for backups .. even offsite backups...

but if "management" takes out the $$$ to do tape backups... so it shall be
done ...
	ideally, everything works ...  but unfortunately, tapes
	are highly prone to people's "oops i forgot to change it
	yesterday"  or the weekly catridge

have fun
