NetWorker Components
Several components make up the NetWorker environment and provide the ability to protect
against data loss.
The following figure illustrates the main components in a NetWorker environment.
.
18 Dell EMC NetWorker Installation Guide
Figure 1 NetWorker components
Introduction
NetWorker Authentication Service
The NetWorker Authentication Service provides centralized token-based authentication to
components in a NetWorker 19.2 environment. You can configure the NetWorker Authentication
Service to use a local user database or external identity providers (LDAP, LDAPS, and AD) for
authentication.
NetWorker Server
The NetWorker Server is a collection of processes and programs that are installed on a host that
performs NetWorker services. The NetWorker Server also acts as a storage node and can control
multiple remote storage nodes.
Dell EMC NetWorker Installation Guide 19
Introduction
NetWorker Server databases
The following table summarizes the different databases that a NetWorker Server uses to manage a
datazone.
Table 3 NetWorker server database functions
Database Function
Client File Index (CFI) Tracks the files that belong to a save set. Each configured
Media database (mm) Tracks the following information:
NetWorker Client has one client file index. The client file indexes can
grow to become prohibitively large over time and can negatively
impact backup performance.
l
The volume name.
l
The location of each save set fragment on the physical media
(file number/file record).
l
The backup dates of the save sets on the volume.
l
The file systems in each save set.
Note: There is only one media database per server.
The media database can grow to become prohibitively large over time
and negatively impact backup performance.
Jobs (jobsdb) Stores, for a limited time, information about NetWorker job
operations, for example:
l
Scheduled and queued backup and recovery operations.
l
Realtime backup and restore related activities.
l
All NMC server communication.
Recovery operations do not require the data that is stored in the
jobsdb database.
Resource (resdb) Stores the configuration information for a NetWorker Server, for
example:
l
v backup configurations.
l
Scheduled recover configurations.
l
Pool configurations.
l
Device configurations.
Client push (cpdb) Stores configuration information for the Client push application.
nsrla Stores configuration information for the NetWorker Remote Exec
(nsrexecd) service.
20 Dell EMC NetWorker Installation Guide
NetWorker Message Queue Adapter
The NetWorker Message Queue Adapter component on the NetWorker Server enables programs
to use the message bus to access the NetWorker Server.
The NetWorker Message Queue Adapter daemon (nsrmqd) translates the communications that
occur between a message protocol and NetWorker Remote Procedure Call (RPC) functions.
The Backup and Recovery Manager software and the Hyper-V File Level Recovery (FLR) feature
in NetWorker Module for Microsoft (NMM) software use the message queue adapter to
communicate with the NetWorker Server and NetWorker Server components.
NetWorker Block-Based Backups
Block-Based Backup (BBB) is a NetWorker software feature that enables you to back up data on a
Windows or Linux host by traversing a volume or disk at the block level.
When you install the NetWorker software on a Window host, the installation automatically installs
the files that the BBB feature requires. On supported 64-bit Linux hosts, install a separate BBB

Introduction
NetWorker Base Client (NetWorker Client)
The NetWorker Client software communicates with the NetWorker Server to support backup and
recover functionality. The software provides you with two client packages: a base client package
and an extended client package. Install the NetWorker Client software on each host that requires
backup and recovery support.
Before you install the NetWorker Client software, ensure that NetWorker supports the specific
client operating system and hardware configuration. The

installs the NetWorker Extended Client package. The NetWorker Base Client installation does not
install the NetWorker Extended Client package.
On UNIX hosts, install a separate NetWorker Extended Client package to enable additional feature
support.
NetWorker Storage Node
NetWorker can back up data to local devices on a NetWorker Server or remote devices on a
storage node. A storage node controls storage devices such as tape drives, disk devices,
autochangers, and silos.
The NetWorker Server is a local storage node. Use a remote storage node to offload most of the
data movement in a backup or a recovery operation from the NetWorker Server. A remote storage
node improves performance, but it requires high I/O bandwidth to manage data transfer from local
clients or network clients to target devices. The operating system of a remote storage node can
differ from the NetWorker Server.
NMC Server
The NetWorker Management Console (NMC) server or Console server is a Java-based application
and database server. The NMC Server manages all NetWorker Servers and Clients. The NMC
Server provides reporting and monitoring capabilities for all NetWorker Servers and Clients in the
environment. The NMC Server relies on the NetWorker Authentication Service for user account
authentication.
NetWorker Management Web UI
The NetWorker Management Web UI is a web-based management interface that you can use to
manage a single NetWorker server. The NWUI Server relies on the NetWorker Authentication
Service for user account authentication.
The
NetWorker Management Web UI Online Help
Datazone
A NetWorker datazone is composed of a single NetWorker Server, its clients, and storage nodes.
You can add additional datazones as backup requirements increase.
NetWorker REST API
provides more information.
The NetWorker REST API is an interface that allows customer to access the NetWorker data
protection service and to build client applications that automate NetWorker operations. The
NetWorker REST API Getting Started Guide
NetWorker REST API Reference Guide
22 Dell EMC NetWorker Installation Guide
describes how to use NetWorker REST API, and the
provides a full description of the API resources.
NMC Client
A NetWorker Management Console (NMC) client is any host in the environment that uses a web
browser and NetWorker Runtime Environment or Java™ Runtime Environment (JRE) to display the
NMC Server GUI. Multiple users can access the NMC Server GUI simultaneously, from different
browser sessions.
NetWorker Daemons
The NetWorker software uses processes on Windows or daemons on UNIX to control and manage
NetWorker operations in the datazone.

Introduction
Note: On Windows platform, after NetWorker server upgrade, the NetWorker services fail to
start, and the daemon.raw logs a message notifying that RabbitMQ service failed to start. To
fix this issue, you must delete the RabbitMQ folder located in C:\Windows
\System32\config\systemprofile\AppData\Roaming file path and restart the
services.
Dell EMC Licensing Solution
NetWorker 9.0.x and later servers use the Dell EMC Licensing Solution.
The Dell EMC Licensing Solution is a licensing standard that stores all licensing information for the
environment in one license file, which is stored on both the NetWorker server and, if using a served
license, the License Server.
All new installations of NetWorker use the Dell EMC Licensing Solution. The chapter "Dell EMC
Licensing Solution" in the
Dell EMC Licensing Solution for new and upgraded installations of the NetWorker software. The
"Dell EMC Licensing Solution" chapter also describes the Dell EMC Licensing Server and the use
of the license file.
NetWorker Licensing Guide
provides information on how to implement the
Front-end Capacity Estimation
NetWorker supports an automatic reporting mechanism that communicates with Dell EMC's Usage
Intelligence portal. You must install the EMC Secure Remote Services (ESRS) appliance version
3.20.20.08 or later from the ESRS Virtual Edition Product Page, and configure NetWorker to
communicate with the appliance. Review the ESRS v3 Installation Training video for details about
how to install the ESRS appliance.
The ESRS RAP resource can be configured to send periodic license, configuration and usage
information to Dell EMC as well as track the liveness of NetWorker servers. Several reports are
sent, the details of the reports are extracted from command line tools.
The command line tool nsrcapinfo, generates an estimate of the total data protected in a
NetWorker datazone. The capacity estimate uses a simple heuristic where it measures the
maximum full backup for each application type and each client in the datazone, this is defined as
the client's capacity. The sum of each individual client's capacity provides a capacity estimate for
the entire datazone. Configuration information is extracted from the RAP database through the
command line tool nsrdump. The nsrdump tool automatically hides sensitive information like
passwords, but can also be configured to hide other information that customers may not wish to
share with Dell EMC.

Software Requirements
NetWorker Authentication Service
NetWorker 19.2 uses the NetWorker Authentication Service to authenticate NetWorker
Management Console (NMC) and command line interface (CLI) users.
To use a Linux NetWorker Server, install and configure the NetWorker Authentication Service
package on the NetWorker Server host before you install NMC Server software.
When you use a Windows NetWorker Server host, the NetWorker Server installation automatically
installs the NetWorker Authentication Service software on the NetWorker Server host.
The NetWorker Authentication Service requires NetWorker Runtime Environment or 64-bit Java 8.
Before you start the NetWorker Server installation, install the Java provided in NetWorker
Runtime Environment or the latest version of the 64-bit Java 8 on the host.
Before you install the NetWorker Server software, ensure that an application does not exist on the
NetWorker Server that uses an Apache Tomcat instance on port 9090. The NetWorker
Authentication Service listens on port 9090 by default. The section "Troubleshooting NMC GUI
and NetWorker Server connection issues" provides more information.
Note: If the installation does not detect NetWorker Runtime Environment, 64-bit Java 8 on the
host, the installation will not continue.
NMC Server Features and System Requirements
The NetWorker Management Console server (NMC Server) enables you to manage, monitor, and
generate reports for multiple NetWorker Servers across multiple datazones and from a single host.
The NMC Server embeds the following software:
l
Apache server, which downloads NMC jar files and starts the NMC Server daemons or
services.
l
PostgreSQL database, which stores reports and the NMC Server configuration information.
The NMC Server software package is supported on a Linux or Microsoft Windows host. The NMC
Server software requires the NetWorker Client software.
You can install the NMC Server software on the NetWorker Server. The minimum system
requirement for a NMC Server host is a 2 CPU processor and 8GB of RAM.
If NMC server is handling a large scale NetWorker server with a large number of users, then size
the NMC server with 32 GB RAM and 8 core CPU, with greater than or equal to 1.5 GHz.
It is recommended that you install the NMC Server software on a host that is not the NetWorker
Server in the following scenarios:
l
When the NMC Server manages a NetWorker Server with 50 or more clients.
l
When the NMC Server monitors multiple datazones.
Multi-locale Datazone Requirements
This section provides guidance for your multi-locale datazone NetWorker installation.
The NetWorker software enables you to configure hosts to run in different locales and supports a
multi-locale datazone. The NetWorker software includes language pack support for French,
Japanese, Simplified Chinese, Korean, and English locales.
The NetWorker command line interface (CLI), the NMC server graphical user interface (NMC
GUI), and the NetWorker User program are I18N compliant.
26 Dell EMC NetWorker Installation Guide
In a multi-locale datazone, you can display data and remotely manage the NetWorker environment
in the locale that is defined on the local host. NetWorker supports different locales on the local
host, the NetWorker server, and the NMC server.
The NetWorker software supports:
l
Languages and character sets that the underlying OS supports.
l
UTF-8 encoded input and output files.
l
Non-English scheduled backup and archive requests.
l
Non-English mounts on UNIX hosts. The NetWorker software detects these mounts during an
All save set backup.
l
Directed recovery to a non-English relocation directory.
l
Save set recovery of a non-English save set, independent of the locale of the source host.
NetWorker Administration Guide

General multi-locale considerations
Before you install the NetWorker software in a multi-locale datazone, consider how textual
elements might display or what message files support localization.
To view localized textual elements in the CLI, the NMC server GUI, and the NetWorker User
application:
l
Install the required language font on the operating system of the host that is accessing the
application interface.
l
Enable the corresponding language locale on the operating system of the host that accesses
the application interface.
l
Enable the corresponding language locale on the NMC server.
l
Install the corresponding language pack, which is included with the NetWorker software
package, on the NetWorker Client, NetWorker Server, NetWorker Storage Node, and NMC
Server.
Software Requirements
describes how to perform NetWorker tasks in a multi-locale
Note:
Textual elements include radio buttons, menu options, dates, times, and numbers.
The NetWorker software does not support locales that the operating system defines or code sets
that remap characters that have a special meaning for file systems, for example De_DE.646.
Depending on the file system, these special characters might include the forward slash (/), the
backward slash (\), the colon (:), or the period(.).
When the non-English font is unavailable on the NMC client, the NMC GUI renders the localized
textual elements in English or the elements might appear as illegible.
The CLI displays the data correctly when the current locale supports the characters and the
encoding. However, when the user and system locales do not match on a Windows host,
characters might display incorrectly.
The nsr_render_log command enables you to render English log file messages to the locale of
the user that runs the command. The
NetWorker Command Reference Guide
or the UNIX man pages
describe how to use the nsr_render_log command.
Message files that support localization include:
l
daemon.raw file—The main NetWorker log file.
l
nsrcpd.raw file—The client push log.
l
gstd.raw file—The NMC server log file.
Dell EMC NetWorker Installation Guide 27
Software Requirements
l
networkr.raw file—The Windows recovery log file.
NetWorker Administration Guide
The
describes how to view raw log files.
Windows requirements for multiple locales
Before you install the NetWorker software on a Windows host in a multi-locale NetWorker
datazone, review the following general locale requirements.
l
When non-UTF8 data from a UNIX host uses encoding that Windows does not support
natively, for example, euc-jp, the data from the UNIX host does not appear correctly in the
NMC GUI on the Windows host.
l
The NetWorker User program displays textual elements, dates, times, and numbers that are
based on the Regional and Language Options settings in the Control Panel.
l
For the French locale and other Latin 1 languages, the NetWorker application uses code page
1252. If the code page for a Windows terminal session is not 1252, CLI commands might not
work correctly. For example, when a code page mismatch occurs between the terminal console
and the recover command, NetWorker cannot mark or add some files when using recover
command. An error message similar to the following appears: <filename> not in index.
To resolve this issue, type chcp=1252 at the Windows command prompt, then type the
recover command.
UNIX requirements for multiple locales
Before you use a UNIX host to connect to the NMC server in a multi-locale NetWorker datazone,
review the following information, which describes how to use non-ASCII installation directories and
how to display non-textual elements.
l
NetWorker does not support a non-ASCII installation directory. Create a symbolic link between
the /nsr folder to a non-ASCII directory.
l
To display non-English textual elements, the dates, the times, and the numbers in the NMC
GUI, ensure that you:
n
Install the NetWorker language package on the client.
n
Define the
installed NetWorker language pack.
For example, on a Solaris host:
LC_ALL
and
LANG
environment variables from a console window, to match the
– To use the French NetWorker language pack, type:
setenv LANG fr
setenv LC_ALL fr
– To use the Japanese NetWorker language pack, type:
setenv LANG ja
setenv LC_ALL ja
– To use the Simplified Chinese NetWorker language pack, type:
setenv LANG zh
setenv LC_ALL zh
– To use the Korean NetWorker language pack, type:
setenv LANG ko
setenv LC_ALL ko
28 Dell EMC NetWorker Installation Guide
Data Domain System Requirements
NetWorker supports Data Domain systems with a minimum version of DDOS 5.7.
Before you install the NetWorker software on the NetWorker hosts, ensure that all Data Domain
systems run a supported DDOS version. The
NetWorker E-LAB Navigator
about the supported DDOS versions.
TCP/IP Requirements
The NetWorker software requires that you install and configure TCP/IP on each host.
Before you install the NetWorker software, ensure that the configuration meets the following
requirements:
l
The /etc/hosts file on each Solaris and Linux NetWorker host must contain an entry for the
IPv4 loopback address. For example, on Linux the /etc/hosts file contains the following
entries by default:
127.0.0.1 localhost localhost.localdomain localhost4
localhost4.localdomain4
Software Requirements
provides more information
. By default, NetWorker supports dual stack. "::1" is required to be in "/etc/hosts" file. If it is
not present, then NetWorker installation adds “::1” to /etc/hosts file.
l
On Windows hosts, NetWorker does not require changes to the hosts file. It is recommended
that you use the default hosts file settings for the IPv4 loopback address on Windows hosts.
l
The NetWorker server, when configured as a DHCP client, must use a reserved address that is
synchronized with DNS.
l
The name of the host that the hostname command returns on the system must match the
name that the IP address resolves to when using the nslookup command.
l
Forward and reverse DNS lookups for the host are successful.
l
Operating system tools, for example, the nslookup command, must resolve the IP address of
the host to the same hostname that you defined for the network adapter that NetWorker uses.
l
The hostname must not contain an underscore character (_).
Note:
On a Linux NetWorker Server, the NetWorker daemons cannot start when the IP
address 127.0.0.1 is inaccessible on the loopback interface. This requirement is true even in an
IPv6-only environment.
NetWorker Management Web UI Browser Requirements
You can install NetWorker Management Web UI and configure it to manage the NetWorker
servers.
The following are the supported web browsers for NetWorker Management Web UI:
l
Google Chrome
