1. Emc Networker Basic

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.

There are four main components of Networker Backup Software.

1. Networker Server

This software get installed on Server ( Windows or Linux Based ) and will provide Services to backup up and recover data on Networker client computers in a Datazone.

Data Zone: Clients, Storage Node and Single Networker Server.

2. Networker Storage Node 

Networker Storage Node Software get installed on Server and will helps in offloading the load from Networker Server. 

How off loading is Done?

1. Without Additional Storage Node.

During Scheduled Backup Networker Server will initiate backup job,Client whose backup to be taken will pass data to Networker Server as Networker Server also behave as Storage Node and then Storage Node i.e Networker Server itself in this case, will pass Data to Destination Storage which can be either Tape Library( Tape Based Storage Device) or Data Domain( Disk Based Storage Device).

2. With Additional Storage Node.

During Scheduled Backup Networker Server will initiate backup job,Client whose backup to be taken will now pass data to additional Storage Node which is configured  and then Storage Node will pass Data to Destination Storage which can be either Tape Library( Tape Based Storage Device) or Data Domain( Disk Based Storage Device).

So here we can see that we have offload the Data Movement load from Networker Server by configuring additional storage Node. Now Networker Server is responsible only for managing purposes.

We define Storage Node in Client Properties under Global ( 2 of 2 ). Based on these values Client will select Storage Node through which its Data Movement will be done. We can have multiple values in Storage Node. 1.2.3.4. Storage Node Selection will be done based on availability. Like if 1 is unavailable due to any reason then it will go to 2.

nsrserverhost is by default and it is Networker Server host itself.

3. NetWorker client

Networker Client is any computer whose Data has to be backed up. 

The NetWorker NMC server, NetWorker servers, and NetWorker storage nodes are also NetWorker clients.

4. Networker Management Console Server- NMC Server

Management of Networker Server and Clients is done by NMC Server. We can install NMC on Networker Server, Storage Node or can have separate Server for it.

NMC server also provides reporting and monitoring capabilities for all NetWorker servers and clients.

Networker Management Console Server Tab are as show below

Button Window Description

Monitoring -Monitor various activities related to the NetWorker server. For example, you can

monitor the progress of a scheduled backup and view any alerts.

Configuration -Manage the NetWorker server and its resources such as clients, backup schedules,

and policies. For example, you can create a backup schedule, add NetWorker clients,

and apply the backup schedule to several NetWorker clients.

Devices -Add, configure, and operate single or multiple devices, libraries, and silos for the

NetWorker server.

Media- Manage activities and resources related to backup volumes. For example, you can mount a backup volume or create a template for labeling backup volumes

Recover: This is a new Recovery Wizard embedded in Networker GUI console from version 8.1 which allows to recover data from centralized location, i.e. NMC GUI itself.
