Sam: Nobody is going without tape. Remember backup and archive are two different things. The practical things the large shops do are use tape for archive purposes, and disk (RAID) subsystems for online and nearline backup. Tape is an inexpensive and easy method for backup, but it is not very practical for restoring (which is all that really matters anyway). Tape can restore at only a small fraction of the speed of disk. If I have terabytes of data to restore, maybe my accounts payable software can wait a few days, but you know payroll or credit card processing can't. So, tape just isn't practical anymore many backup/recovery requirements. Years ago, it was the only option you had. Now, advancements in disk speed and price makes tape unacceptable for data recovery. For archiving, however, tape is king and will remain that way until a new technology can replace it. David
