I agree with you George. A Hot Swappable SCSI NAS or SAN is far more cost effective than the tried and true tape backup. The only advantage tape has now is that tape, like floppy is portable so you can store tapes off site with minimal cost and fuss. You can do the same with drives but accidentally dropping a drive while shipping it off somewhere or banging around isn't good. Accidenally dropping a tape isn't likely to cause the problems that dropping a drive does.

Tape will go the way of floppy disks with NAS and SAN. It's only a matter of time.
