Networker Notes

The EMC NetWorker environment

The EMC NetWorker environment provides the ability to protect an enterprise against dataloss. As the enterprise grows, so does the complexity and importance of protecting data.

NetWorker software provides the power and flexibility to meet these challenges.

The NetWorker software is a cross-platform, client-server application that provides the

ability to remotely manage all NetWorker clients and servers from a web-enabled, graphicalinterface.

NetWorker components

Console server

All NetWorker servers and clients are managed from the NetWorker Console server. TheConsole server also provides reporting and monitoring capabilities for all NetWorker serversand clients.

Console user interface

The Console server is accessed through a graphical interface that can be run from any

computer that has a supported web browser and Java Runtime Environment (JRE). TheNetWorker Installation Guide provides information on supported web browsers and versionsof the JRE. Multiple users can access the Console server concurrently from different browser

sessions. A computer that hosts the web browser can also be a NetWorker client.

NetWorker server

NetWorker servers provide services to back up and recover data for the NetWorker clientcomputers in a datazone.

Datazone

A datazone is a single NetWorker server and its client computers. Datazones can be added

as backup requirements increase.

NetWorker storage node

A NetWorker storage node can be used to improve performance by offloading from theNetWorker server much of the data movement involved in a backup or recovery operation.

NetWorker client

A NetWorker client computer is any computer whose data must be backed up. The

NetWorker Console server, NetWorker servers, and NetWorker storage nodes are also

NetWorker clients.

Deduplication nodes

NetWorker supports EMC Avamar and Data Domain deduplication. The NetWorker AvamarIntegration Guide provides detailed information about setting up Avamar deduplication to

work with NetWorker. The NetWorker Data Domain Deduplication Devices Integration Guide

provides detailed information about setting up Data Domain deduplication to work withNetWorker.

Virtual environments

NetWorker clients can be created for virtual machines for either traditional backup orVMware Consolidated Backup (VCB). Additionally, the NetWorker software can automatically

discover virtual environments and changes to those environments on either a scheduled oron-demand basis and provides a graphical view of those environments.

NetWorker bare metal recovery (BMR) HomeBase Server

A NetWorker BMR server is an EMC HomeBase Server that manages and restores operatingsystem and server state data, collected as profiles. The HomeBase Server is the collection

point for profiles produced by HomeBase Agents. HomeBase Agents are automaticallyinstalled with the NetWorker client software. The profile data includes:

hardware configurations operating system levels system tuning network connections security

storage layouts.

The HomeBase Agent captures this information on a scheduled basis with a NetWorker saveset, and sends the profile results to a HomeBase Server for management and analysis.

A BMR recovery enables the restoration or migration of a server from one hardware type toanother. This type of recovery begins with the HomeBase Server and the profile data that is

gathered and includes the file system and application data restore from the NetWorker

server through the Console server.

HomeBase Server installation is separate from NetWorker server installation. The HomeBase

Server must be configured and available when:

A BMR client resource is created.

BMR backup data (profiles) are generated from NetWorker clients.

Networker Features

Performance features

Standard NetWorker performance features include:

Server parallelism, which enables several save streams to flow to the server orstorage node at the same time.

Multiplexing enables more than one save stream to write to the same device at thesame time.

Client parallelism, which enables the client to send more than one save stream at atime. Session management, which enables one to control the number of save streams per

device to maximize the performance of each device.

Backup to file-based devices and optional subsequent staging and cloning to near-line or offline volumes.

Backup to a cloud storage configuration.Ease of use

3/7

NetWorker software provides tools to make protection of critical data easy to manage. With

these tools, you can:

Use either the graphical interfaces or command-line programs to manage NetWorker tasks

and functions.

Use wizards to set up the following NetWorker items:

Client resources AFTD and Data Domain devices Common Console configuration tasks LDAP user authentication Administer and configure NetWorker functions from any network computer with a

web browser.

Grant permission to provide directed recovery operations. Directed recovery is thecapability for recovery of one client's data to another client computer.

Obtain immediate answers to questions by accessing online help and UNIX manpages. Microsoft Windows users can also access the NetWorker command referenceguide, which provides information similar to the UNIX man pages.

Take advantage of the automatic media management feature to enable theNetWorker server or storage node to label and mount volumes as needed forbackups.

Drag-and-drop functionality allows for an easy transfer of single or multiple objects. Use the integrated knowledge base and technical bulletins at the EMC Powerlink

website to find answers to common questions. Automatically discover and view a graphical map of virtual environments. Set up NetWorker Console server authentication to an external LDAP v3.1 compliant

server.

Support for automated Windows Disaster Recovery.Scalability

NetWorker software can be scaled as storage management needs grow. For example, youcan:

Upgrade the basic level of server functionality, add support for additional (or larger)autochangers, add support for more clients, or add optional software modules

without the need to reinstall the server software. Add special NetWorker Module client software to back up databases and other non-

file-system data.

Add support for remote storage nodes to control backup devices, while the datamanagement tasks remain centralized on a controlling NetWorker server.

Add the NetWorker License Manager (NLM) software to administer all of yournetwork's EMC software licenses from a single server.

Optional software additions

Optional additions to the NetWorker software include:

NetWorker Autochanger Module NetWorker Silo Software Module NetWorker Archive Module NetWorker Database Modules (for backing up several types of databases) NetWorker SNMP (Simple Network Management Protocol)

IPv4 to IPv6 transition

Internet Protocol version 6 or IPv6 is designed to replace the current Internet Protocolwhich is IPv4. IPv6 fixes a number of problems in IPv4, such as the limited number of

available IPv4 addresses. It also adds many improvements to IPv4 in areas such as routingand network auto configuration. IPv6 is expected to gradually replace IPv4, with the two

coexisting for a number of years during a transition period. The NetWorker Installation

Guide provides information about using NetWorker in an IPv6 environment.
