Backup and storage management in distributed heterogeneous environments

Abstract

Powerful but nevertheless easy-to-operate systems for backing up and reconstructing data from clients are necessary in a distributed heterogeneous environment. The concept of the Siemens Nixdorf Informationssysteme (SNI) AG is based on a client/server model. It runs under the control of a SINIX server and includes backup clients for various Unix systems, PCs such as those with MS-DOS/Windows, and PCs in the Novell NetWare network. Logical data backup and restore actions for any file or disk partition in a Unix system and for any file in a PC system can be performed automatically and at defined times during an operation. The backup media are tapes, DAT cartridges, magneto-optical disks, and associated autochangers and jukeboxes.<>
