I agree, we use this approach as well. NDMP has scaling issues, doesn't
play nicely with TSM incremental backups or include/exclude lists, and ties
you into a single storage vendor for both backups and restores. That last
point is particularly scary for anyone writing DR plans, since who knows
what storage you'll end up with after a real disaster.
