Mountain View, CA and Sunnyvale, CA - March 20, 2002 -- Legato Systems, Inc. (NASDAQ: LGTO), a worldwide leader in enterprise software management solutions and Network Appliance, Inc. (NASDAQ: NTAP), a leading provider of enterprise storage solutions, today announced that Legato NetWorker® and Legato RepliStor™ support Network Appliance NearStore R100 solutions. NearStore provides customers with massive storage capacity using inexpensive disk technology for applications including backup and recovery of heterogeneous systems, data migration, and archival of infrequently accessed content. This joint effort delivers high-performance, disk-based protection for increasing amounts of data and cost-effective file-level replication for business continuity.

The combination of Legato NetWorker and Legato RepliStor with Network Appliance NearStore R100 provides customers with easy-to-deploy and easy-to-manage solutions that scale quickly to meet the ever-growing demands of today's enterprise and business customers at a competitive price point.

With more than 100,000 server licenses worldwide, Legato NetWorker protects the business-critical information of enterprise customers by simplifying and centralizing backup and recovery operations across heterogeneous environments. Built upon an open, highly scalable architecture, NetWorker reduces management overhead by automating the protection of storage assets in data centers and branch offices. NetWorker leverages the high-capacity disk storage aspects of the NearStore R100 by protecting terabytes of information quickly and efficiently. Providing optimum manageability, data can be backed up and recovered from disk and staged before moving to tape. Legato NetWorker and the Network Appliance NearStore R100 are extremely scalable, enabling businesses to protect critical information in less time and reduce downtime costs.

Legato RepliStor and the Network Appliance NearStore R100 provide flexible and cost-effective asynchronous data replication for high availability and rapid recovery of business-critical data residing on Windows NT® and Windows® 2000. In conjunction with NetApp® Snapshot™ technology, Legato RepliStor can economically protect data online by efficiently storing multiple point-in-time copies of data on the NearStore R100, enabling end users or administrators to perform much faster tapeless restores and centralized tape backups.

"Network Appliance and Legato customers can be confident that the storage technologies they're deploying deliver significant value while providing data protection and consistent high availability of that information," said Charles A. Fonner, vice president of worldwide marketing and strategic alliances, Legato Systems. "This announcement is part of a long and fruitful relationship with Network Appliance, developed through a shared vision to provide the highest levels of data storage and availability solutions to customers worldwide."

"Network Appliance and Legato Systems both recognize that customers require solutions that ensure business continuance, but without unnecessary levels of complexity," said Mark Santora, senior vice president of marketing at Network Appliance. "Legato's ability to offer support for our latest solutions gives enterprises the flexibility to cost-effectively protect their data, using technologies that work together seamlessly. This drastically reduces administration overhead as well as significantly lowers TCO."
