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 )

are highly prone to people's "oops i forgot to change it
yesterday" or the weekly catridge
