ADIC and Stac Announce Certification for Replica and ADIC's Full Line of DAT & DLT Autoloaders -- Combination Offers Increased Data Storage Management Protection For Network Managers.

REDMOND, Wash.--(BUSINESS WIRE)--Sept. 5, 1996--ADIC, a division of Interpoint Corp. (NASDAQ:INTP), and Stac Inc. (NASDAQ:STAC) today announced the full certification of Stac's ReplicaTM 2.1 disaster recovery and backup software with support for ADIC's full line of DAT & DLT autoloaders: ADIC's 1200 Series, VLS 4mm Series, and VLS DLT Series.

In combination, Stac's award-winning disaster recovery and backup software and ADIC's 4mm & DLT autoloaders provide a fully automated desktop data protection and management system that gives system managers and individual users immediate access to up to 490GBs of stored data, and native transfer rates up to 300 MB/minute.

"With our customers reporting storage rates growing at 50 to 100% annually, LAN managers need the tools that the combination of Replica and ADIC autoloaders provide to help them manage the critical task of protecting data," commented Bill Britts, ADIC sales and marketing vice president. "Together, they give users a proven, high performance system which fully automates data protection and disaster recovery while providing the highest levels of control and flexibility."

Replica 2.1 is a simple and powerful disaster recovery and backup solution for NetWare servers that is complete, easy to use and extremely fast. Replica's patent-pending Logical Object Replication TechnologyTM enables complete server recovery, including DOS and NetWare as well as user data, with just three keystrokes, two disaster recovery diskettes and a tape. Additionally, system administrators can store replicated data on the same server, a standby server, or a streaming tape drive and then mount the tape directly as a NetWare volume with full NetWare security in place.

Users can then access and restore files themselves using familiar tools such as Windows FileManager without administrator assistance. Replica 2.1's new 7/24 Live Server Replication enables the server to have complete read/write activity during replication without interrupting users' daily routine. Users are no longer required to log off during backup and no open file errors occur.

ADIC's 4mm and DLT autoloaders were designed to increase data security and reduce system administration overhead by providing fully automated backup operations. The ADIC 1200 Series is the industry's leading 4mm desk-top library, providing fully automated backup with a total capacity of up to 96GB (12 DAT cartridges). The ADIC VLS 4mm series is a high performance dual-drive automated tape storage system suitable for enterprise wide backup and archiving, providing a total capacity of up to 120GB. Both products offer the new Sony Quad-Speed SDT-7000 4mm DDS-2, with transfer rates of 90 MB/minute -- 50% faster than standard 4mm DDS-2 and 8mm drives.

ADIC's VLS DLT Series delivers the performance to back up today's growing networks within the constraints of limited backup windows. It offers the latest in DLT tape drive technology, including the new DLT7000 drive with transfer rates of up to 300 MB/minute (native) and capacity of up to 490GB.

"ADIC and Stac both have a history of pioneering advances in data storage. We supply a powerful combination of automation, performance and ease-of-use," said Michael W. Harris, director of Stac's Storage Management Group. "Our combined efforts provide network administrators with systems that protect data reliably, efficiently and economically."
