Well, I learned that lesson WAY back when I first started sysadminning, my own 
'My First Server' was a HP/Apollo HPUX box running Sybase database server, and 
backed up to a 1G DAT drive religiously, using tar.

Then one day I accidentally dropped an important database table, and learned 
the hard way that tar does not back up open files.

Like database data files, which are always open while the database is running.

As Titus' dad used to say "Betcha won't do THAT again!"

Sadly, this is how most places like this learn the lesson, the hard way.

I'd try very hard to prevail upon them to at least invest in new sets of tapes 
and, suggest, gently that they practice restoring some files from backup, now, 
while everything is fine, so that they're not doing this for the first time 
when the system's gone down and people are screaming for their data, pounding 
on your door with pitchforks and torches. Pitchforks and torches are very 
distracting and not optimal for learning new things :-)

That'll lead them right to the bad tapes, no doubt.
