“With the DD460 from Data Domain, we’ve been able to compress and store two to three months of backup data onsite. We’ve cut costs and reduced our reliance on offsite tape storage, and we can back up and restore data at incredible speeds. Best of all, we can easily verify the security and integrity of our data. We’re very pleased — the DD460 is everything we’d hoped for.” — Ephraim Baron

Data Domain Granted New Patent for Accelerated Deduplication Technology

New patent covers key techniques for maximizing system throughput of Capacity Optimized Storage solutions with less RAM

Santa Clara, CA — August 14, 2006 — Data Domain, the leading provider of Capacity Optimized Storage (COS) solutions, announced today that that the U.S. Patent and Trademark Office has granted Data Domain Patent Number 7,065,619 entitled “Efficient Data Storage System.” This patent covers key technologies to allow inline deduplication of data at high speed.

Comparing incoming small sequences of data with petabytes of stored data to check for redundancy is normally either high cost or very slow, or both. Data Domain has protected a method that reduces RAM requirements by several orders of magnitude, while also minimizing disk accesses. In combination with its other patents, this allows Data Domain to provide the best price/performance disk arrays in the Capacity Optimized Storage market and to deliver extremely efficient WAN replication and vaulting products for disaster recovery.

“In deduplication, the challenge is to maximize throughput at low cost,” said Dr. Hugo Patterson, Chief Architect for Data Domain. “Through the work highlighted in this patent, Data Domain has established a reliable mechanism that’s proven to be highly effective in hundreds of enterprise deployments. We expect that the techniques protected under this patent will provide us a continuing distinct competitive advantage in the marketplace.”

Data Domain has multiple patents pending in the area of capacity optimization. With Data Domain’s innovations, its systems can perform at high throughput and also enable end-to-end data integrity and recoverability verification at backup time. The patent’s inventors are Data Domain Senior Architect and co-founder Ben Zhu, Chief Architect Dr. Hugo Patterson, and Chief Scientist and co-founder Dr. Kai Li who is also a Charles Fitzmorris Professor of Computer Science at Princeton University. The patent references important prior work by Burton H. Bloom, Andrei Z. Broder, and Udi Manber.

“Data Domain’s deduplication technology is the cornerstone of our data protection solutions,” said Frank Slootman, president and CEO of Data Domain. “The approach we’ve employed not only accelerates throughput, but enables our solutions to scale both upwards and downwards without excessive application of expensive hardware. This patent not only serves to protect the techniques we use today for accelerating throughput, but going forward we expect it will offer a basis of continued differentiation as the Capacity Optimized Storage market grows.”
