— Data Protection Leader Recognized for Innovative,
Reliable Technology and Commitment to Channel —

Oceanport, NJ — July 22, 2008

• CommVault (NASDAQ: CVLT) today announced it has been selected by Everything Channel as a CRN Emerging Tech Vendor for its CommVault® Simpana® 7.0 Software suite. CRN's Emerging Tech Vendor list captures companies that are delivering high margins for solution providers with innovative and easy-to-use technology that is more attractive than industry giants.
• While the number of CommVault's enterprise deals, which consist of software transactions greater than $100,000, grew 51% in fiscal year 2008 and accounted for 41% of license revenues in the quarter ended March 30, 2008, in addition to the CRN Emerging Tech Vendor list, CRN acknowledged CommVault for its work serving the midmarket as well, as one of the "Hottest Midmarket Companies Right Now."
• The CommVault Simpana software suite, adopted by thousands of customers since its introduction in July of last year, helps address the problems end-users face as they try to manage data to fulfill their current data protection, risk mitigation, disaster recovery, or archive and compliance requirements. CommVault sells the Simpana software suite to both end users and as a licensed application for channel partners looking to offer advanced data and information management software as a service (SaaS).
• CommVault's unique Singular Information Management® approach transforms the way customers manage and access their information by providing a single, holistic view across application silos and storage tiers through a single data and information management platform. Today, customers can take advantage of CommVault technology to streamline storage management, improve data reliability and service levels and reduce the cost of protecting IT infrastructures. This approach not only helps IT organizations improve the access and availability of data but also lowers infrastructure complexity and costs while enabling customers to better respond to new business demands.
• CommVault's on-going success can be attributed to the contributions of its reseller partners. Through The CommVault Partner Network, CommVault provides sales, technical resources and support to train resellers and support their selling and services efforts. The CommVault Partner Network and new developments in the partner program will also allow top VARs increased access to Microsoft selling tools in North America through VAR-led seminars and campaigns.
• According to CRN, vendors who make the CRN Emerging Tech Vendor list must have, among other things, an established solution provider program, formal guidelines for recruiting channel partners and must not be a dominant market share player. Final selection to the Emerging Tech Vendor list was made at the discretion of the CRN editorial team after a review of the submitted information and conversations with current or targeted partners.
