Oceanport, N.J. - November 8, 2004 -- CommVault®, a provider of Unified Data Management solutions, today launched the second generation of its QiNetix Unified Data Management software suite. This second generation QiNetix software allows a customer's IT department to place data on the optimum storage medium, matching cost, access and recoverability to service level requirements. Unlike competitive solutions consisting of a loose collection of separate point products, CommVault's QiNetix suite is built on a common technology platform eliminating the need for users to build and maintain multiple back-end repositories to manage data access and availability for different business needs. This major new release has robust capabilities to help customers recover data faster in complex, heterogeneous networked storage environments as well as automate lifecycle policy operations by the intelligent cooperation of different QiNetix modules.

"While its competitors are just starting to talk about the value of integrated data management solutions, CommVault is way ahead with its QiNetix Unified Data Management platform," said Steve Duplessie, founder and senior analyst, Enterprise Strategy Group. "New and enhanced features further separate them from the competition, and give users the functionality they need today - improving the quality and speed of data recovery, simplifying backup while taking full advantage of solutions like disk-based backup - this is more of what users need, and CommVault continues to deliver."

CommVault recently posted 12 consecutive quarters of double-digit, year-on-year revenue growth. The company currently has over 2,000 customers with QiNetix products installed at more than 2,800 sites. The QiNetix suite includes backup/recovery, replication, automated data migration, archiving, storage resource management and service level management features. From a single console, the suite components share automated policy management and common job and event managers on the front-end and distributed metadata indexes, media management, and copy management on the back-end. The new QiNetix suite further leverages the efficiencies of the Unified Data Management platform to ease, automate and reduce the cost of data management. Significant new enhancements take data recovery to a higher degree of service than other products on the market.

"With this latest release of QiNetix, CommVault has once again demonstrated that they listen to our requirements and quickly deliver robust data and storage management software that protects data, cuts costs and makes our jobs easier," said David Free, an IT network systems consultant, from a large California-based insurance company. "Here, we have 36 sites where data and storage need to be managed, a monumental task if done with point products. With the QiNetix unified approach, we have a centralized view of our data and storage that lets us keep our finger on the pulse and adjust operations to meet our service levels."

Customers will particularly benefit in two key areas: faster recovery and smarter management of tiered storage environments.

Faster Recovery
QiNetix enhances capabilities to speed recovery time from individual files to full applications and provides unified views of protected data. It integrates several technologies to recover data as quickly as needed.

With the new and expanded offerings, QiNetix customers can:
