Agreed and there's more than one way to skin the cat. If you have a lot 
of data to backup, tape just takes too long and disk based backup is far 
more effective. The approach here is the have a pair of raid 5 groups 
mirrored by rsync daily, which are themselves mirrored to another 
machine  in a different location once a week, again using rsync across 
the network. It's essentially free, just works, is faster than tape and 
can be automated via scripts...
