18 Dell EMC NetWorker Installation Guide

Introduction

Figure 1 NetWorker components

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

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
	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.

Media database (mm)	Tracks the following information:
	•	The volume name.
	• The location of each save set fragment on the physical media
		(file number/file record).
	• The backup dates of the save sets on the volume.
	• 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:
	• Scheduled and queued backup and recovery operations.
	• Realtime backup and restore related activities.
	• 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:
	•	v backup configurations.
	•	Scheduled recover configurations.
	•	Pool configurations.
	•	Device configurations.

Client push (cpdb)	Stores configuration information for the Client push application.

nsrla	Stores configuration information for the NetWorker Remote Exec
	(nsrexecd) service.

Introduction

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 software package to provide a NetWorker host with BBB support.

The NetWorker E-LAB Navigator provides more information about operating system support for BBB.

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 NetWorker E-LAB Navigator provides the most up-to-date information about compatibility.

NetWorker Extended Client package

The NetWorker software includes an NetWorker Extended Client package, which provides NetWorker hosts with additional feature support.

Install the NetWorker Extended Client package if you require the following functionality on the host:

•NetWorker Snapshot Management (NSM)

•Network Attached Storage (NAS) snapshot

•CLI utilities for server reporting and administration, for example mminfo and nsrinfo

•Firewall tunneling tools

•Cluster integration scripts

•Custom script integration tools (pre/post save)

•Audit log

•NetWorker Module for Meditech

•SCVMM Data Protection Add-in for NMM

Dell EMC NetWorker Installation Guide

Introduction

•Recovery of NetWorker Module for Microsoft (NMM) 8.2.3 and 8.2.4 backups by using NMM

•Cloning and staging

•ProtectPoint for VMAX

•ProtectPoint for Recoverpoint

On Windows hosts, the NetWorker Server or NetWorker Storage Node installation automatically 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 provides more information.

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

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 describes how to use NetWorker REST API, and the NetWorker REST API Reference Guide provides a full description of the API resources.

Introduction

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.

This table lists the NetWorker daemons for each software component.

Table 4 Daemons on a NetWorker host

Software component	Daemons


NetWorker Authentication Service	java.exe (Windows), jsvc.exec
	(UNIX)
NetWorker Server	nsrd, nsrexecd, nsrindexd, nsrmmdbd,
	nsrmmd, nsrjobd, nsrmmgd, nsrlcpd,

For more information about the NetWorker processes, review the following information:

•The nsrmmd daemon or the nsrmmd.exe process is present on a NetWorker Server or storage node that has one or more enabled devices.

•The nsrmmgd daemon or the nsrmmgd.exe process is present on the NetWorker Server when a media manager is enabled.

•The nsrlcpd daemon or the nsrlcpd.exe process is present on a NetWorker Server and storage nodes when an attached tape library exists.

•The nsrcpd daemon or the nsrcpd.exe process is present on the NetWorker Server during a Package Manager software upgrade.

The NMC Server daemon, gstd, starts these additional processes:

•postgres: The ProgreSQL database daemon on Linux. On Windows, the service associated with the postgres.exe process is EMC GST Database Service.

•httpd: The web server daemon on Linux. On Windows, the service associated with the httpd.exe process is EMC GST Web service. There are 2 or more httpd daemons.

•gstsnmptrapd: An optional daemon that is present on a Linux NMC Server when SNMP Trap monitoring is configured for a Data Domain system. On Windows, the service associated with gstsnmptrapd.exe process is EMC GST Trap Handler.

Dell EMC NetWorker Installation Guide

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 NetWorker Licensing Guide provides information on how to implement 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.

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.

The NetWorker Command Reference Guide provides more details on nsrcapinfo.

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:

•Apache server, which downloads NMC jar files and starts the NMC Server daemons or services.

•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:

•When the NMC Server manages a NetWorker Server with 50 or more clients.

•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

Software Requirements

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:

•Languages and character sets that the underlying OS supports.

•UTF-8 encoded input and output files.

•Non-English scheduled backup and archive requests.

•Non-English mounts on UNIX hosts. The NetWorker software detects these mounts during an All save set backup.

•Directed recovery to a non-English relocation directory.

•Save set recovery of a non-English save set, independent of the locale of the source host.

The NetWorker Administration Guide describes how to perform NetWorker tasks in a multi-locale datazone.

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:

•Install the required language font on the operating system of the host that is accessing the application interface.

•Enable the corresponding language locale on the operating system of the host that accesses the application interface.

•Enable the corresponding language locale on the NMC server.

•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.

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:

•daemon.raw file—The main NetWorker log file.

•nsrcpd.raw file—The client push log.

•gstd.raw file—The NMC server log file.

Dell EMC NetWorker Installation Guide

Software Requirements

•networkr.raw file—The Windows recovery log file.

The NetWorker Administration Guide 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.

•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.

•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.

•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.

•NetWorker does not support a non-ASCII installation directory. Create a symbolic link between the /nsr folder to a non-ASCII directory.

•To display non-English textual elements, the dates, the times, and the numbers in the NMC GUI, ensure that you:

nInstall the NetWorker language package on the client.

nDefine the LC_ALL and LANG environment variables from a console window, to match the installed NetWorker language pack.

For example, on a Solaris host:

–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

Software Requirements

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 provides more information 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:

•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

. 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.

•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.

•The NetWorker server, when configured as a DHCP client, must use a reserved address that is synchronized with DNS.

•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.

•Forward and reverse DNS lookups for the host are successful.

•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.

•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:

•Google Chrome

•Mozilla Firefox

•Microsoft Edge

•Microsoft Internet Explorer 11
