One of the most tedious and complex jobs in the world of IT used to be data backup. Not anymore.
This paper first examines the state of the industry relative to Disk-to-Disk (D2D) adoption. It explores the issues
- tape backup
- cost aspects of new, less expensive disk with capacity optimization
- tangible and intangible benefits of moving to D2D
The second half of the paper discusses financial analysis such as Total Cost of Ownership (TCO), Return on Investment (ROI) and payback periods and how they can build a strong business case for D2D and Capacity Optimized Storage (COS). We present three case studies of actual users who are moving from tape to D2D in varying degrees (from disk backup as nearline storage with no changes in tape backup procedures, to a complete elimination of tape).

It's a straightforward discussion of the technology and where it fits.

Too Many Backup and Archiving Options Confusing the Issue?
Why Traditional Methods - Tape, Disk, and Archiving Fall Short.
