Legent Corp has added network back-up and storage software packages as Reliance/XP. There is a new hierarchical storage management software for Sun Microsystems Inc, Hewlett-Packard Co and IBM Corp Unixes called Reliance/XP Open Storage Manager. It does not replace existing files systems, the company says, but migrates them to disk, leaving stub files behind to provide a consistent file system view. Now up under Solaris 2.4 and on HP 9000 Series 700s, it costs from $6,500 to $25,000 for a 20Gb system. Reliance/XP will feature on RS/6000s from June. Reliance/XP Network Backup & Restore is built from the Alexandria Backup Librarian software Legent is taking OEM from Boulder, Colorado-based Spectra Logic Inc. It is up under Sun, Hewlett-Packard and IBM Unixes and supporting Spectra Logic, Exabyte Corp and Odetics Inc storage systems, and prices start from $6,500, rising to $25,000 on one server, 25 clients and support for two relational databases. Spectra Logic will add support to Alexandria for Legent’s AgentWorks for managing systems, network and databases. Legent claims the Unix-based Network Backup & Restore will not supersede or conflict with its existing ESM Computer Service Inc back-up software for OS/2 and Windows NT local networks. Network Backup & Restore is up against the likes of Epoch, Computer Associates and Legato offerings.
