Yes, I know that this is the ideal solution.

However, this is an office with naive computer users, and a bunch of
servers.  Experience has taught me not to rely too heavily on
non-technical people to change tapes ;>  It is more important that we
get a good backup _every_ night, than to have somebody forget to change
the magazine, and go without backups for several days ;<
