Companies Team to Increase Scope of Compatibility Testing and Align Go-to-Market Strategies for Data Protection Solutions SANTA CLARA, CA -- (MARKET WIRE) -- 03/22/07 -- Data Domain, a leading provider of Enterprise Protection Storage systems for disk backup and network-based disaster recovery, today announced that it has achieved the status of CommVault(R) Strategic Partner. CommVault, a leading provider of Unified Data Management(R) solutions, extends Strategic Partnership status to a select group of solution providers that have demonstrated an investment in time and resources to team with CommVault's technical, marketing and sales forces to deliver joint solutions. Data Domain is already a member in CommVault's PartnerAdvantage(TM) program. As a strategic partner, enterprise customers will benefit from Data Domain's elevated status since the two companies now will expand their compatibility testing and further align their go-to-market strategies to bring enhanced data protection offerings to market. The combination of Data Domain's deduplication-enabled Enterprise Protection Storage systems and CommVault Galaxy(R) backup and recovery have already allowed numerous enterprises to enjoy high performance disk-based backup and disaster recovery solutions that reduce costs and work more efficiently than tape-based solutions. "CommVault and Data Domain already have a strong relationship and a demonstrated track record of success together in the backup space," said Beth White, vice president of marketing at Data Domain. "Going forward, our goal is to further optimize our technologies for data protection application environments. Together, CommVault and Data Domain can offer solutions that leverage our respective strengths for the benefit of enterprise users." CommVault software products all use CommVault's Common Technology Engine (CTE) architecture, a unique scalable framework optimized for data management. Offering a suite of unified data protection, replication and storage resource management solutions that are built on a common set of management services, including secure data movement, a common management console interface, and shared device management, CommVault enables customers to meet their data management needs with a single software solution. "End users are demanding data protection solutions that reduce the complexity of managing data in enterprise IT environments, and interoperability is key to successfully deploying these solutions today," said Dave West, vice president of marketing and business development, CommVault. "We are pleased to collaborate with Data Domain to bring our jointly certified solutions to market and extend the benefit of our combined data protection expertise to our joint customers." Seattle-based Korry Electronics is a world leading manufacturer of electro-optical cockpit control and display solutions and a user of both CommVault's data management products and Data Domain's Enterprise Protection Storage systems. Korry Electronics first implemented Data Domain and CommVault products in November of 2006. "The power and simplicity of the CommVault/Data Domain value proposition is something Korry Electronics has experienced firsthand," said Raul Tabile, network administrator, Korry Electronics. "The Sunday evening after this past Thanksgiving, our Exchange server experienced a severe failure. The only solution was to perform a complete server restore. Normally, if it worked, our old restore from tape process would have taken about 8 hours. With our new CommVault/Data Domain solution, that same restore only took 20 minutes! The combination of Data Domain and CommVault saved us from what would certainly have been an administrative nightmare and could have compromised our service to users the following Monday morning. Given that their existing solutions already work so well together, the extension of CommVault and Data Domain's partnership is great news."
