  The place I came to work had a dying $5,000 tape deck that they couldn't 
afford to repair, and 80 GB tapes that they couldn't afford to replace 
because they cost about $80 each, and they were dying after a year or two 
(probably because the deck was bad, but they were replacing these tapes 
after a year anyway as standard practice). We ended up using spare space 
on several servers for the backups, which has been much less work and more 
reliable. My longer-term proposal was to buy a pile of 200 GB hard drives 
for about $80 each and have backups performed and rotated automatically. 
As far as reliability, these hard drives could be stored unpowered - or in 
a massive RAID-5, the functionality would be monitored in real time, and 
the chance of a double drive failure affecting a periodic backup that 
happened to be needed seems remote.

  Yours,

    Chris
