OCEANPORT, N.J. — October 15, 2003 — CommVault® Systems, Inc., a provider of unified enterprise data management solutions, today announced the availability of QiNetix™ DataMigrator™ Version 5.0 software that includes substantial platform, performance and integration enhancements. The DataMigrator solution lets customers move fixed content, such as files or e-mail, to less costly secondary storage, thereby immediately reducing storage cost and backup windows. Because DataMigrator retains transparent end user access to information, it reduces training and administration normally associated with implementing some hierarchical storage management strategies.

DataMigrator's policy-based lifecycle approach helps IT organizations manage access and storage by matching cost and performance of storage resources to the business value of application data. By providing unified management across different copies of data (nearline and offline), DataMigrator software helps to optimize storage utilization, expand end user access, shrink backup windows and improve application operational performance, thus lowering overall storage costs.

QiNetix DataMigrator Version 5.0 delivers many enhancements that include:

• Expanded platform support — Solaris file system support. Plus, new capabilities have been added to already supported environments including:

  • Microsoft Windows — includes 64-bit support, cluster support and migration of international character filenames.

  • Microsoft Exchange — enhanced migration rules and:

    • Outlook Web Access (OWA) support — view, differentiate and work with files in the OWA client view. Easy auto-recall function included.

    • .PST message migration support — migrate all message/attachment data to location designated by associated storage policy. Ensures centralized and uniform handling of e-mail across the organization. Eliminates need for end users to manage the size of their inbox.

• Performance enhancements — significantly faster message and file recall provides greater transparency for the end user. Dramatically reduces wait time and offers superior end user experience.

• Full integration with QiNetix Common Technology Engine (CTE) — utilizes proven QiNetix data movement, management, collection and preservation technologies and robust media management that are common to all QiNetix solutions. The CTE eliminates the need to set up and integrate separate vaulting, backup and HSM storage processes to implement a full information lifecycle management solution. DataMigrator can easily be combined with the QiNetix Storage Manager software module to provide assessment, monitoring and reporting of Microsoft Exchange application and Windows file systems environments. QiNetix Storage Manager enables customers with better intelligence to determine and tune criteria for migration strategies as well as measure and report on results.

"CommVault is proud to announce DataMigrator Version 5.0," said Bob Hammer, chairman and CEO of CommVault Systems. "DataMigrator has a great track record for helping customers manage storage capacity and reduce costs by storing data on secondary media. Our customers continue to point to DataMigrator as another crucial component in helping them map and optimize their data management processes across tiered storage-letting them leverage their storage resources, greatly reduce costs and maximum data access. Such benefits are crucial to the success of their businesses."
