With 180-GB IDE (and soon Serial ATA/USB/FireWire) disks now becoming 
mainstream, 1 TB RAID-Sets costing $3K-5K will become a compelling case as 
backup medium. Today's IDE/ATA-based RAID NAS systems and commodity PC 
motherboards with the ability to have up to 8 IDE/ATA Discs (or a 7+1P 
RAID-5Set/or 8-Disk Concat) would allow data centers to have very fast backup 
media that could be offsited as conveniently as Tape media.  If it is indeed 
true that disk to disk backups now require a separate license in NetWorker - 
then I guess that is an acknowldegement that the day of disk based backups has 
finally arrived...
