Diligent Technologies' HyperFactor Technology Defines the Future of De-Duplication for Enterprise Networks.

Diligent's HyperFactor(TM) Technology "Encapsulates Where Capacity Optimization Will Be Heading in the Coming Years" According to New Taneja Group Report

FRAMINGHAM, Mass. -- Diligent Technologies Corporation, a leading provider of enterprise data protection solutions, today announced the availability of a new report that validates the unique capabilities of its HyperFactor(TM) data de-duplication technology. HyperFactor powers Diligent's ProtecTIER enterprise-class disk-based data protection solution and provides customers with an efficient, secure and reliable backup, recovery and archive solution.

"All enterprises with significant data protection requirements need to be looking seriously at how to control their data growth and disk-based storage capacities. Advanced de-duplication technologies like HyperFactor are now the best weapons in the arsenal," said Arun Taneja, analyst and founder of the Taneja Group. "Without question, enterprises evaluating their options for capacity optimization in D2D need to understand this proven technology from Diligent Technologies."

The Taneja report describes how it sees Diligent Technologies on the cutting-edge of a burgeoning market it terms capacity optimization. Capacity Optimization (CO) is the term Taneja Group uses to describe technologies that cut down an enterprise's physical storage requirements for secondary disc storage. Taneja Group says Diligent, with its ProtecTIER VT solution and its "secret sauce" - HyperFactor - stand out as extremely scalable, efficient, high-performance data de-duplication software and that its ability to de-duplicate data at 25:1, at in-line rates of 200 MB/s is "mind bending" and sets this technology apart as second to none.

"We are happy with the findings of the Taneja Group report. It is in line with the experiences of dozens of ProtecTIER enterprise customers who are able to dramatically transform their data-protection operations by improving the reliability and performance of their backup and restore, increasing the economical retention of backup and archive data on disk and eliminating trucks as a means for transporting data to disaster recovery and archive sites," said Doron Kempel, Chairman and CEO of Diligent Technologies. "Reducing the amount of physical space needed to store vital information is absolutely needed in enterprises of all sizes. By dramatically reducing the costs of storing and transporting data, Diligent's ProtecTIER is pushing the envelope of data protection effectiveness."

According to the validation report, HyperFactor can reduce capacities anywhere from 10:1 to 25:1 or more, depending on workload type and retention periods. Taneja Group states when this optimization efficiency is coupled with HyperFactor's scalability, it translates into some boggling figures: HyperFactor can scale to support 25 petabytes of managed data, which it will optimize down to a 1 petabyte physical storage repository, all managed under a single 4GB RAM index. The group adds that because of Diligent's breakthroughs in indexing design, HyperFactor's index can map an entire data repository at 250,000:1 ratio, which is an unprecedented level of efficiency. In contrast, hash-based algorithms require an index in orders of magnitude higher and are penalized with complex recoveries, performance degradation and the possibility of data integrity issues.

The report, "Diligent HyperFactor: Redefining De-Duplication" is available online at both Diligent Technologies' (www.diligent.com) and the Taneja Group's (www.tanejagroup.com) Web sites.
