Cheyenne Software Announces Advanced Data Management Services for the Windows NT Market; ARCserve for Windows NT Further Extends Cheyenne's Architecture for Reliable Managed Storage (ARMS) Strategy for Providing Storage Management Across Heterogeneous Networks.

ROSLYN HEIGHTS, N.Y.--(BUSINESS WIRE)--November 7, 1994-- Cheyenne Software Inc. (AMEX:CYE), a leading provider of LAN-based storage management software, today announced ARCserve for Windows NT, a native Microsoft(R) Windows NT(TM) operating system-based backup and restore software solution.

The development of ARCserve for Windows NT solidifies Cheyenne's commitment to the maturing Windows NT market, in addition to bringing the company closer to realizing its technological vision as outlined in its ARMS (Architecture for Reliable Managed Storage) strategy, for delivering essential data management services across diverse enterprise computing environments.

ARCserve for Windows NT will provide the same high performance features as Cheyenne ARCserve for NetWare - Windows Edition, customized for the Windows NT environment. As a result of Windows NT's growing acceptance as a database server, throughout 1995 Cheyenne will make available optional database agents for ARCserve for Windows NT, enabling on-line backup of database servers, such as Oracle and SQL Server.

"We are pleased that Cheyenne Software is moving their popular ARCserve product to Windows NT. More and more business customers are standardizing on Windows NT Server as their platform for file, print, communication, and application server needs," said Jim Allchin, Vice President Business Systems Division, Microsoft. "Robust data management is a key reason why customers trust the BackOffice environment. ARCserve fits into this architecture nicely. ARCserve takes advantage of Windows NT services and security to meet customer's needs for unattended operations, and safeguards their corporate data."

"Hewlett-Packard Company's multi-year partnership with Cheyenne, the leading developer of server-based software, has enabled us to provide our customers with a range of storage management solutions to match their requirements," noted Robert Hill, marketing manager for HP's Computer Peripherals Bristol Division. "We're pleased that such a high-level of proven technology has been designed to support HP's DAT drives and autochangers."

"We look forward to the release of ARCserve for Windows NT," said Kelly Landreth, MicroLAN Manager for Southwest Oncology Group at Fred Hutchinson Cancer Research Center in Seattle. "One of the reasons we chose the Cheyenne backup software for Windows NT is Cheyenne's understanding of, and experience in, implementing a single approach for multiple clients and network operating systems."

ARCserve for Windows NT will offer many of the same powerful features as Cheyenne ARCserve for NetWare, including support for three levels of data verification ranging from none to complete byte-by-byte comparison with the disk, as well as the easy-to-use Windows(TM) operating system interface. Session password protection and network and file security, which protect backup session and files from unauthorized access are also offered in ARCserve for Windows NT.

Because it is 32-bit architected, and was developed specifically for the Windows NT environment, ARCserve for Windows NT has been optimized for Windows NT's advanced operating system and networking capabilities and functions as an operating system service rather than an application. Older 16-bit applications require Windows NT to emulate a Microsoft Windows-based environment resulting in degraded performance.

ARCserve for Windows NT was designed for easy porting to various CPU architectures. The initial release which is scheduled to begin shipping by the end of calendar year 1994, supports the Intel-based platform, which will be followed by support for other RISC-based machines, such as MIPS and Alpha, with other platforms to be added based on customer demand. Most leading peripheral devices will be supported upon release of the product.

"Windows NT is quickly becoming a significant element on the network," noted Jon Greene, Cheyenne ARCserve for Windows NT product manager. "As our customers' networks become more diversified, Cheyenne continues to strive to deliver the right solution for the intelligent storage of information, no matter what the environment."

Amplifying its commitment to the Windows NT market, Cheyenne is also currently developing native Windows NT-compatible versions of its integrated client/server anti-virus software solution, InocuLAN, as well as its NLM-based, high-performance, network facsimile product, FAXserve.

ARCserve for Windows NT will be available through the company's worldwide network of distributors and resellers. The U.S. suggested retail price is $895.00. Autochanger support will be offered as an optional software module, for unattended backup of large file systems, at a U.S. suggested retail price of $595.00.
