OCEANPORT, N.J.--(BUSINESS WIRE)--Sept. 24, 2002

New Release Offers .NET Support, Document-level

Recovery for SharePoint Portal Server and

Expanded Granular Restore for Exchange Public Folders

Extending its position as the leading data protection solution provider for Microsoft enterprises, CommVault(R) Systems, Inc. today announced new levels of data protection specifically for Microsoft-based enterprises in version 4.1 of its CommVault(R) Galaxy(TM) data and storage management software. Through extremely close collaboration with Microsoft, CommVault now offers the most complete, flexible and robust Microsoft enterprise data protection available. Features specific to version 4.1 include:

-- Support for and seamless integration with Microsoft's .NET operating system, to simplify the implementation process and accelerate upgrades to .NET enterprises

-- The ability to perform "document-level" recovery for SharePoint Portal Server data files, speeding the restoration of the most critical enterprise data and minimizing business disruption

-- Robust scalability and parallel processing capabilities to reduce data backup windows and minimize enterprise downtime

-- Enhanced testing with Microsoft covering security and firewall port protection

-- Expansion of "granular restore" capabilities for Exchange Public Folders, offering IT management maximized flexibility and control during the recovery process to avoid redundant restoration routines and prioritize restoration of mission-critical data sets

"At CommVault, we made a fairly dramatic 'turnabout' decision in 1998 to focus first on developing backup solutions using Microsoft technology as a foundation," said Bob Hammer, CEO of CommVault Systems. "We have since extended our concept of application- and file-centric restoration out to all major enterprise platforms, and have steadily extended Galaxy's market share. Tight integration with Windows and .NET, however, remains a guiding principle in our strategy of providing new standards of speed and simplicity to companies seeking to minimize both the 'human costs' associated with data administration, and the revenue lost when data can't be recovered quickly and easily."

CommVault Galaxy software benefits include:

-- Simple -- "all-in-one" centralized, browser-based interface

designed to simplify management, training and installation, as

well as provide a single, streamlined view of global data

resources. Galaxy Storage Policies let IT staff logically

manage SAN, NAS & LAN data in complex enterprise networks, and

spans both Windows and UNIX platforms.

-- Speedy -- high-performance, fast data restoration to business

users at the application level, including LAN-free,

Server-free and Serverless data protection schemes

-- Seamless -- unified product; built from the ground up to

seamlessly scale in the most popular storage networking

environments
