and Tru64

The Java based NetWorker Management Console (NMC) software, which is bundled with the NetWorker distribution, provides a user interface for functions such as client configuration, policy settings, schedules, monitoring, reports, and daily operations for deduplicated and non-deduplicated backups.

The core NetWorker software backs up client file systems and operating system environment. Add-on database and application modules provide backup services for products such as Oracle, DB2, SAP, Lotus, Informix, and Sybase, as well as Microsoft Exchange Server, SharePoint, and SQL Server. Client backup data can be sent to a remote NetWorker storage node or stored on a locally attached device by the use of a dedicated storage node.

NetWorker PowerSnap modules automate the generation of point-in-time data snapshots and cloning on supported storage arrays such as EMC CLARiiON, and Symmetrix. The NDMP
