Advanced Functionality Preserves Information Across Archive and

Backup Data Sets to Help Mitigate Risks Associated with eDiscovery

OCEANPORT, N.J.--(BUSINESS WIRE)--June 25, 2008--CommVault (NASDAQ: CVLT):

    --  Responding to the need for organizations to preserve and
        protect their information when litigation is reasonably
        anticipated, CommVault (NASDAQ: CVLT) today announced the
        availability of an advanced Legal Hold feature set, extending
        the capabilities of the eDiscovery features in the
        CommVault(R) Simpana(R) 7.0 software suite.

    --  CommVault's Legal Hold capability spans both archive and
        backup stores to help ensure information is preserved. By
        maintaining a legally defensible audit trail, these features
        allow customers to reduce the risks associated with
        non-compliance with regulations such as the US Federal Rules
        of Civil Procedure (FRCP) for eDiscovery as well as preserving
        the evidentiary integrity of content for court submission.

    --  With powerful features and no need for additional licensing to
        enable a wide-ranging eDiscovery toolkit, the Legal Hold
        capability uses a comprehensive, automated approach to search
        and retrieve data from backups, archives or any Electronically
        Stored Information (ESI) - such as emails and files - and
        retain a subset of the data for long-term accessibility.
        CommVault Legal Hold helps customers defensibly preserve
        responsive information that may already be under multiple
        retention policies. CommVault's Legal Hold also embraces
        object level holds, beyond file-based, for a granular level of
        recovery for both vaulted backup sets and archives at the
        message or document level.

    --  Post-hold considerations are also supported within the Legal
        Hold feature set, allowing post-hold data and content to be
        retained or removed as required.

Industry Demand for Legal Hold Solutions Calls for Sophisticated Features and Combined Archive and Backup Stores

   -- A legal hold is a process used by an organization to preserve
       all forms of relevant information when litigation is reasonably
       anticipated.

   -- Unlike traditional Legal Hold technologies which treat archives
       as a single entity and only tag messages located inside the
       archived storage pool, CommVault's Legal Hold feature spans
       both backups and archives, preserving data in all storage pools
       based on normal retention policies.

   -- Not limited to legal action, users abiding by internal
       governance rules can also leverage the Legal Hold feature set
       for adherence to company policies that mandate the retention
       and disposal of certain documents and information.

   -- As a result of CommVault's unique Singular Information
       Management(R) approach to Legal Hold, specific features and
       benefits are made available to customers including:

       -- Advanced search result views which allow users to utilize
           annotation tags and organize search results;

       -- Powerful filters that enable users to quickly identify and
           reduce the number of files and email messages needed for
           review to make better legal decisions, meet deadlines and
           avoid sanctions;

       -- Giving users the ability to save queries and control how
           results are displayed. This allows relevant items to then
           be easily designated for Legal Hold where collections are
           defined by case-specific retention rules; and

       -- Flexible post-hold management capabilities allow the
           reclassification, consolidation and/or timely destruction
           of held content, regardless of infrastructure.

    Supporting Quotes:

    --  CommVault software has helped to mitigate the pain of backup
        and recovery and has allowed my IT team to make significant
        progress in meeting legal, compliance and discovery demands,
        said Sarita Bennett, IT Policy and Projects manager,
        Carmarthenshire County Council in the United Kingdom. The
        ability to leverage these capabilities from a singular,
        unified console has saved us time in training, overall storage
        management and everyday archiving functions.

    --  ESG Research suggests that one out of every two
        organizations, regardless of size or industry, have been
        through an electronic discovery event in the past twelve
        months. As such, they are forced to preserve more and more
        information to meet legal hold requirements. Properly managing
        ongoing retention requirements creates additional IT overhead
        and costs, said Brian Babineau, senior analyst, Enterprise
        Strategy Group. CommVault Simpana software offers robust
        flexibility for organizations dealing with recurring
        electronic discovery requests, particularly those in post-hold
        activity, by offering reclassification of held content, data
        movement and consolidation with existing data stores, across
        backup, archive or both.

    --  We believe the fact that electronic evidence may be scattered
        across countless locations and diverse electronic formats has
        increased the risk organizations face when preparing for
        pre-trial conferences or litigation proceedings, said Michael
        Marchi, vice president of product and segment marketing,
        CommVault. With CommVault's unique Singular Information
        Management approach, however, ESI is managed from one standard
        interface and pooled into a single repository for collection.
        This makes implementing CommVault for legal hold and
        preservation a much easier, lower risk proposition for many
        enterprises than purchasing separate point solutions and
        cobbling them together.

    --  Today, the CommVault Simpana suite is the only product on the
        market that offers customers a single unified management
        platform that combines data protection, archiving, search,
        replication and resource management technologies, thereby
        eliminating the need for customers to deploy multiple point
        solutions and enabling added benefits including increased cost
        and operational savings, added Marchi.
