STORAGE NETWORKING WORLD, ORLANDO, FL. — April 8, 2008 — As businesses struggle to balance organizational risk, CommVault (NASDAQ: CVLT) today announced new product updates to its Simpana® 7.0 Software Suite that provide users with expanded data protection and information management capabilities. The new updates include: Advanced eDiscovery/Legal Hold Capabilities, Enhanced Remote Office Data Protection with Disk Based Backup and Archive, Broadened Storage Resource Management capabilities, as well as support for key Microsoft applications. These updates will help customers ensure business continuity in the face of potential disaster and comply with regulatory requirements for data retention and availability.

"In order for data and information management solutions to be effective, they must keep pace with the rapidly evolving storage environment and align with business needs," said Michael Marchi, CommVault's vice president of product and segment marketing. "By delivering regular product updates, we are providing our users with the assurance that their CommVault data protection and information management solutions have the latest technology needed to mitigate organizational risk and keep data available in the event of a discovery request or business failure."

With a unique, singular approach to data and information management, CommVault continues to address customers' evolving needs by providing unified data protection and information management technologies designed to support an IT environment that is increasingly aligned with the changing demands of their businesses. By deploying a Singular Information Management® model, customers can maximize their existing heterogeneous IT infrastructure, reduce business risk and lower the overall cost of their hardware spend. This ROI methodology and CommVault's comprehensive approach to meeting the data availability requirements of businesses today, has received acclaim from storage industry analysts.

"Organizations not only need to align IT and business strategies with their data protection and information management solutions, but also take the complexity, cost and risk out of the equation," said Lauren Whitehouse, analyst, Enterprise Strategy Group.  "Leading the convergence charge for a few years now with its Singular Information Management model, CommVault has kept these requirements in mind and is simplifying the protection and discovery of information, while also adding business value."

The CommVault® Simpana 7.0 suite addresses the data protection and information management needs of enterprise businesses with the following key features and benefits:

• Advanced eDiscovery/Legal Hold Capabilities: A Legal Hold requires organizations to protect and preserve all of the information that is pertinent to a particular legal matter. In order to assist users in safeguarding their evidence, CommVault has unveiled advanced eDiscovery and Legal Hold capabilities. Advanced search result views provide virtual working collections of search hits allowing users to innovatively utilize annotation tags and organize search results. Powerful filters enable users to quickly cull down and reduce the number of files and email messages needed for review. Additionally, new usability features provide users with flexibility to save queries and control how results are displayed. Relevant items can then be easily designated for Legal Hold where collections are defined by case-specific retention rules. Legal Hold carries forward the full benefits of the CommVault Simpana platform (WORM media, reporting, group-based security, encryption, and multi-site support for dual copy requirements). These new features enable CommVault users to easily perform Advanced eDiscovery/Legal Hold functions and deliver actionable intelligence from their stored information across backup stores, email, file and document archiving policies resulting in lower discovery costs and early case assessments.

• Enhanced Remote Office Data Protection with Disk Based Backup and Archive: Enhancements to CommVault Continuous Data Replicator (CDR) lets users combine the power of replication with the bandwidth efficiencies and disk savings of single instance storage (SIS) for backup and archive data. By transferring only deduplicated data, CDR expedites the process of copying backup or archive data to a central location over a WAN or a LAN for secondary processing. This cost-effective, hardware independent solution is ideal for centrally managing data from multiple remote locations for content indexing, search, encryption and backup to tape, without impacting remote systems.

• Broadened Storage Resource Management with Added Platform and Application Support: With increased support for Linux operating systems and Microsoft 64-bit technologies, new features in CommVault Storage Manager 7.0 automate the identification of different data types, growth trends, and cost metrics across complex heterogeneous environments, enabling users to adopt a proactive approach to tracking and analyzing data with intuitive information management capabilities. These new management features give users the ability to administer storage pools, allocate new volumes when necessary, and forecast disk/tape growth and purchases for business cost savings.

Additionally, CommVault also introduced today increased support for Windows Server 2008. As businesses rapidly upgrade to new Microsoft technologies, IT users are demanding the ability to restore files from earlier versions of Windows, Linux and UNIX platforms. This flexibility helps ensure that customers can comply with regulatory requirements for retention and availability of data across Microsoft e-mails and documents, while leveraging the speed and performance of the Windows Server 2008 environment and applications such as Exchange Server that relies on Windows Server 2008. The CommVault Simpana suite is optimized to take advantage of the rich performance benefits of the 64-bit versions of Windows Server 2008 to help customers speed recovery and improve the performance of disk-based environments.
