OCEANPORT, N.J.--(BUSINESS WIRE)--Jan. 4, 1999--

-- OEM Agreement Offers CommVault Customers a Broad Range of

Standard Interface Devices and Ability to

Share Drives and Libraries --

Continuing to form strategic partnerships that strengthen its comprehensive storage management solutions, CommVault Systems(R), Inc. today announced a strategic Original Equipment Manufacturer (OEM) license agreement with Legato Systems, Inc. Through this agreement, CommVault will license and integrate Legato's SmartMedia(R) into its future family of enterprise-wide storage management products and storage area network (SAN) offerings.

"The integration of Legato SmartMedia ensures our enterprise storage management product will support a broad range of devices through standard interfaces," said Larry Cormier, CommVault's vice president of marketing and business development. "The ability to transparently share drives and libraries across different applications and systems is vital to controlling storage costs in the open systems arena."

This agreement will enable CommVault to swiftly adapt to evolution in the storage arena where new tape and optical storage technologies are competing for enterprise acceptance. In addition, a comprehensive media management solution will lower administrative costs and deliver a higher level of data protection by automating manual functions.

"Legato SmartMedia enables enterprises to reduce their overall cost of storage by providing robust media management solutions. We are excited to offer this product to our strategic partners," said Nora M. Denzel, senior vice president at Legato Systems, Inc. "Our partnership with CommVault is a natural fit in the enterprise arena, where the implementation of traditional client/server models, as well as emerging shared storage environments, can utilize Legato SmartMedia for device sharing."

This agreement further strengthens CommVault's commitment to deliver to its customers the most comprehensive and powerful enterprise storage management solutions available. By partnering with leading storage providers such as Legato Systems to help quickly expand the Company's storage management capabilities and service offerings, CommVault can more rapidly implement its vision of a comprehensive storage management solution. The CommVault solution offers its customers the following key benefits:

Application Integration

With unmatched integration capabilities, the CommVault solution quickly restores application data at the file, folder, mailbox or component level with all of the unique properties associated with the data intact. For example, documents with associated security clearance properties or e-mail boxes with attached files and associated addresses can be fully and individually restored. CommVault software recognizes the data within integrated applications as objects, capturing the permissions, rights and metadata associated with that data. Many competing approaches back up files and applications as straight bit stream data or file systems that require restoring an entire database or e-mail system to extract and restore a single document or folder. The granularity of the CommVault backup allows the software to quickly locate and individually restore only the requested data in seconds without any excess baggage.

Storage Management Foundation

CommVault's centralized storage management suite is the only storage management solution that is based on a single architectural foundation offering a built-in, tight integration of all storage management functions to meet enterprise user needs. These include:

-- File System and Database Backup and Recovery, -- Disaster Recovery, -- Hierarchical Storage Management, -- Archiving, and -- Data Migration.
