Oliver Wyman, a global strategy consulting firm, was engaged by NetApp to conduct primary research on the cost of acquiring, deploying, managing, and maintaining data backup environments used to ensure the safety and security of corporate data. The NetApp objective for this study was to understand the total cost in typical enterprise deployments of two competing backup technologies: NetApp SnapVault® disk-todisk backup systems and traditional tape-based backup technologies. The findings included in this report are Oliver Wyman's, based exclusively on specific data provided by the backup operators, storage administrators, and IT managers who participated in this study.
