-- Early Adopter Program Validates Strategy -- Wins Over 500 Accounts, including Spacelabs Medical --

OCEANPORT, N.J. — May 11, 2005 — CommVault®, a provider of Unified Data Management™ solutions, today announced that since its launch in January, 2005, Galaxy Express software has been adopted by Spacelabs Medical and over 500 other small- and medium-business customers demanding easier, more cost effective ways to manage explosive data growth with limited resources. Customers chose Galaxy Express for its enhanced, easy-to-use backup features and aggressive SMB-price. This software's success further demonstrates CommVault's customer commitment and is a significant step in CommVault's strategy of providing powerful, integrated and easy to use products that seamlessly scale in customers' storage environments.

"We are a Galaxy Express customer and are extremely happy with our purchase decision and implementation at our new UK site," said Andrew Dutton, Senior Systems Administrator, Spacelabs Medical. "Galaxy Express has made a positive impact on our IT operation. We had to find a solution that fit the size, budget and requirements for our new infrastructure. In the past we have been challenged with remote backup processes and products that caused administrative headaches, lost data and downtime. With Galaxy Express, we alleviate the administrative overhead, have faster restores and know that our data is always there if we need it. And, as our needs evolve, Galaxy Express can grow with us."

Galaxy Express is a feature sub-set of the enterprise Galaxy product, specifically targeted to meet the needs of small-to-medium businesses requiring reliable, simple and cost effective data protection. Customers choose Galaxy Express over competitive products for two reasons: Robust features and investment protection. Contrary to other products, Galaxy and Galaxy Express are built on a common code base which "future-protects" the customer- they do not have to deploy a new product when their environment expands and requirements change, which is often the case. With a simple purchase of an enabler key, customers can easily upgrade to the full Galaxy product as opposed to a "forklift upgrade" with other vendor point solutions. This approach eliminates software changes, migrations, retraining and other problems associated with upgrades of competitive products. In addition, the CommVault products can be expanded to provide a platform for advanced data management functions including, hierarchical storage management, archiving for compliance, and replication for high availability.

"While other vendors talk about how critical unified solutions are, CommVault is the only company offering solutions built on a unified platform," said Arun Taneja, Founder, President and Consulting Analyst at Taneja Group. "The company understands the data management needs and differences within the enterprise and SMB markets. It has carefully designed Galaxy Express software so the out-of-the-box experience for SMB users meets their business needs and expertise level. The advantage of CommVault's common platform is that as SMB customers' data management requirements evolve and grow, they can easily take advantage of the higher-level functions and the additional capabilities of the unified data management suite."

CommVault software was recently honored by Senior IT Executives attending the Midsize Enterprise Summit (produced by Vision Events®, a Gartner, Inc. company) for demonstrating the highest level of innovation and excellence in the software category.

Bob Hammer, CommVault's chairman and CEO said, "This program's success fulfills an important part of our long term business strategy — high volume distribution in the SMB space. Coupled with the large enterprise segment's continued, rapid adoption of our QiNetix products, this further solidifies a broad distribution engine for the future."
