I realize that this thread is old, but I wanted to add what we are planning to do:
We were saving our footage to DVDs but that is not the best way to do it and a cataloging nightmare!
So we have purchased a Quantum LTO-3 Tabletop Drive, we didn't want to have to maintain a large amount of on-line media and I didn't want to worry about it crashing. The tapes hold about 400GB or 800GB compressed and are about $50 each - not too bad.
Now we also purchased the Network Tape Gateway system to add a keyword search and proxy to our archive. I actually have not recieved it yet, but I recommend you take a look at:

Since we are a smaller station without a large budget this still cost us around $17K, but will save us money when we are not looking through hundreds of old DVDs and reshooting footage.
Best of luck!
