Global data deduplication can yield significant capacity savings, but its most attractive feature may be the architecture it's built upon. The buzz around data deduplication continues unabated. Based on our experience, many IT users have already deployed data deduplication to some extent in their data centers. And many of those who haven't taken the dedupe plunge are planning to in 2011. Still, we estimate that only approximately 20% of worldwide enterprise data is protected on disk, with another 50% still to be added to that number. The rest will stay on tape or remain unprotected.

And many of those are wondering if global deduplication might actually deliver more efficiency across large amounts of data.
