Agreement Strengthens CommVault's Position in Near-Continuous Data Protection Market

OCEANPORT, N.J. and SANTA CLARA, Calif., March 7, 2007 /PRNewswire-FirstCall via COMTEX News Network/ -- CommVault(R) (Nasdaq: CVLT), a leading provider of Unified Data Management(R) solutions, today announced that it has extended its existing OEM agreement with Hitachi Data Systems Corporation, a wholly-owned subsidiary of Hitachi, Ltd. (NYSE: HIT), to include CommVault Continuous Data Replicator. Under the agreement, Hitachi Data Systems, which already co-brands CommVault's suite of data management solutions under the banner "Hitachi Data Protection Suite, Powered By CommVault(R)", will begin selling Hitachi Continuous Data Replicator across all of Hitachi Data Systems' worldwide market segments to help customers address their remote office data protection needs.

"Furthering the long-standing and profitable relationship between our two companies, this agreement builds on the mutual strengths of our product portfolios," said David West, CommVault's vice president business development and marketing. "Today's announcement signifies a strategic expansion of CommVault's addressable worldwide market, solidifying our efforts to expand beyond backup to bring near-continuous data protection (near-CDP) capabilities to customers with remote office data protection needs."

The agreement complements Hitachi's line of midrange storage systems and enterprise storage platforms with a near-CDP software offering targeted at smaller remote offices, where the need to optimize storage and bandwidth while lowering operational costs is paramount. According to Enterprise Strategy Group research, 89 percent of remote and branch office (ROBO) locations backup to on-site storage resources. As interest in remote backup grows, Enterprise Strategy Group found that 40 percent of organizations that do not currently use any remote backup technologies say they expect to deploy such technologies, with 19 percent expecting to deploy in the next 24 months.

"Unprotected or inadequately protected assets at ROBOs expose companies to data loss and compliance risk, and leave organizations vulnerable to loss of productivity and revenue," said Lauren Whitehouse, analyst at Enterprise Strategy Group. "Hitachi Continuous Data Replicator streamlines backup consolidation, thereby increasing operational efficiencies at ROBOs and centralizing data protection."

"For many companies, protecting remote office data can be a challenge that is both costly and cumbersome," said Jack Domme, executive vice president, Global Solutions Strategy and Development, Hitachi Data Systems. "Extending our partnership with CommVault to offer complementary best-in-class remote office data protection capabilities as part of the Hitachi Data Protection Suite, builds on our commitment to help customers centralize the management of remote office data and provide cost-effective disaster recovery."

Hitachi Continuous Data Replicator copies file changes of all remote data to a central location where customers may then use Hitachi Backup and Recovery software to back up the replicated data rather than the data on the source server. As IT managers look to adopt storage technologies that provide cost-effective protection of their company's mission-critical information regardless of where it resides, the seamless integration between Hitachi Continuous Data Replicator and Hitachi Backup and Recovery allows customers to achieve new levels of near real-time local and remote data recovery.
