EMC NetWorker
EMC NetWorker (formerly Legato NetWorker) is a suite of enterprise level data protection software that unifies and automates backup to tape, disk-based, and flash-based storage media across physical and virtual environments for granular and disaster recovery. Cross-platform support is provided for Linux, Windows, Macintosh, NetWare, OpenVMS and Unix environments. Deduplication of backup data is provided by integration with EMC Data Domain (DD Boost) and EMC Avamar storage solutions.
A central NetWorker server manages a datazone that contains backup clients and NetWorker storage nodes that access the backup media. Platforms supported by the core NetWorker server are: AIX, HP-UX, Linux, Solaris SPARC & x64, SGI IRIX 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 module can be used for client-less backups of NAS Filers like EMC Celerra or Netapp.
VMware virtual machines can be directly backed up either by installing the NetWorker client on the virtual machine or through the VMware vStorage API (VADP) provided by VMware.
NetWorker also supports backup and recovery of Microsoft Windows Server 2008 and Hyper-V virtual servers by using the Volume Shadow Copy Services interface. This support protects the parent and child partitions (guests) as well as applications running within the virtual machines.
History
NetWorker came to EMC by the acquisition of Legato in October 2003.
Legato was founded in 1988 by four individuals who worked together at Sun Microsystems: Jon Kepecs, Bob Lyon, Joe Moran and Russell Sandberg.
