Demystifying Data De-Duplication:
Choosing the Right Solution
Selecting a data de-duplication solution that enables cost effective,
high performance, and scalable long-term data storage
A WHITE PAPER




Abstract: Data de-duplication has been described as “the next evolutionary
step in backup technology.” Many vendors lay claim to the best data de-
duplication approach, leaving customers to face the difficulty of separating
hype from reality. A number of key factors must be considered in order to
select a data de-duplication solution that actually delivers cost-effective,
high-performance, and scalable long-term data storage. This document
provides the background information required to make an informed data
de-duplication purchasing decision.

Executive Summary
In the August 2006 report from the Clipper Group entitled 'The Evolution of Backups - Part Two -
Improving Capacity', Dianne McAdam said, “De-duplication is the next evolutionary step in backup
technology.” Eliminating duplicate data in secondary storage archives can slash media costs, streamline
management tasks, and minimize the bandwidth required to replicate data.
