In bed with tape - Computerworld:

Divorce is never easy.

"While elminating tape is technically feasible, there are several roadblocks that will in all likelihood prevent this, all of them economic."

Tape == pain. However, no Tape == More Pain.

Go figure.

"For those truly committed to the no-tapes vision, don't despair. I would suggest considering products that incorporate aggressive data-reduction technologies, such as delta-block differencing or commonality factoring, which can store backup data in a fraction of what would otherwise be required. Companies like Avamar Technologies, ExaGrid, Data Domain and others are pioneering the use of these and other technologies to make disk-only backup feasible."

If you're truly committed to a no-tape future, then I'm pretty sure your budget is a lot bigger than mine.
