When I still had a DLT-IV drive I considered DVD media to be very cost effective when you consider the difference ( 100X or more) in price of tape drives. But then with DVDs you will be spending a lot more time loading the media (I guess unless you get that 250 disk autochanger that was mentioned on the list last week). And then there is reliability. I from my own experiences I can easily say that DVD media is less reliable than tape but it does depend on several factors. I would never use RW media for a backup and always make at least 2 copies of your data if you are archiving and you should always verify a dvd backup after running it as if a disk is defective there is a chance that it will write without any errors but be totally unreadable after. I had that happen two weeks ago at home.
