ADIC and Network Appliance Team to Deliver Proven Data Protection Solutions

Redmond, WA and Sunnyvale, CA - March 20, 2002 -- Advanced Digital Information Corporation (NASDAQ: ADIC), the leader in Intelligent Storage™ solutions, and Network Appliance (NASDAQ: NTAP), a leading provider of enterprise storage solutions, today announced comprehensive mutual support for multitiered data protection applications using ADIC's scalable line of automated tape storage systems and the new Network Appliance NearStore R100 storage platform.

The NearStore R100 provides very large-scale network storage capacities using inexpensive disk technology. ADIC's tape libraries provide a full range of intelligent automated systems for backing up and restoring data to tape in a broad range of SCSI, SAN, and NAS environments. Together, the Network Appliance NearStore R100 and ADIC tape libraries will allow end users to cost-effectively consolidate backup of multiple NetApp® filers and other storage devices into a unified system that combines proven long-term data protection with rapid data recovery and ease of deployment.

The new, multitiered data protection system allows users to consolidate backups from multiple NetApp filers to a NearStore R100, using Network Appliance SnapVault™ software, then back it up to an ADIC tape library in background mode using industry-standard data protection software. The data is protected in a centralized ADIC library with full media management, off-site vaulting, and media rotation control, while duplicate copies of recent data are kept on NearStore R100 to provide rapid recovery. The system gives end users a centralized backup system with a single management interface, and it provides faster access to the most recent backup data.

"The NearStore R100 is an innovative tool for IT departments struggling to protect their data in the most cost-effective way," commented Bill Britts, ADIC executive vice president of sales and marketing. "Our ongoing development and support work with Network Appliance has proven that using large, inexpensive disks as active cache and a medium-term storage location can play a key role in many users' backup plans, saving them time and money while increasing their overall data security."

"ADIC and Network Appliance are working together to deliver advanced, complementary solutions that provide greater levels of data protection while reducing administrative overhead as well as TCO," said Mark Santora, senior vice president of marketing at Network Appliance. "We continue to broaden the scope of our storage solutions to meet expanding customer needs and believe that combining our solutions offers enterprises extended functionality."
