Data stored on tapes is a lot more stable than data on spinning disks, even when sitting on a shelf. I certainly would not replace a tape backup with spinning disk backups - rather, I would use the disks for routine backups and tapes for quarterly archives or similar. Although, for some of our systems, we use rotated tapes nightly. There's a good reason so many folks still use tapes for important systems.
