The three primary types of NetWorker hosts in a NetWorker Data Zone are the NetWorker server, storage node(s), and clients.
A single NetWorker server, along with its storage nodes and clients, forms a NetWorker Data Zone within which data is protected.
An enterprise may have more than one NetWorker data zone, however, NetWorker servers and storage nodes may belong to only one data zone.
NetWorker clients may be backed up by multiple NetWorker servers and therefore, may belong to multiple data zones.
Additionally, NetWorker provides the ability to create multiple restricted data zones (RDZ) on a single NetWorker server to support multi-tenancy requirements of organizations like IT service providers and cloud hosting providers

The NetWorker Client is the largest and most fundamental NetWorker software component. The client’s most important functions are to generate backups called save sets, push them to a NetWorker storage node, and retrieve them during a recovery. NetWorker clients are usually the data servers in an IT environment. The types of data that are typically backed up as save sets include file system data and applications.
While performing a backup, the client also generates tracking information, including the file and directory names in the backup and the time of the backup, and sends it to the server to facilitate browsable Point In Time (PIT) recoveries.
Depending on the specific operating system, the client software may contain graphical user interfaces and command line utilities that allow users to manually perform backup and recovery operations.
Every host in a NetWorker data zone is a NetWorker client. NetWorker client software is installed on all participating hosts in the data zone, including hosts that also play the roles of server and storage node.

NetWorker Storage Nodes are hosts with directly-attached or SAN/LAN-accessible devices to support the storage of backup data.
During a backup, a NetWorker client sends backup data to a particular storage node based on that client’s configuration. The storage node organizes the client’s data and writes the client’s data to one of its devices.
Storage nodes also send tracking information about the save sets written to the volume during the backup to the NetWorker server. This information is used for future backups as well as for recoveries.
During a recovery, the client reads from the storage node. The storage node provides the device that contains the necessary volume.
The NetWorker server is always a storage node and is the default storage node for backups. A NetWorker server can manage many storage nodes, but a NetWorker storage node can be managed by only one NetWorker server. In other words, a storage node cannot exist in two data zones at the same time. Storage node hosts have both the NetWorker client and storage node software installed

The NetWorker Server manages and supports client backups and recoveries. It is the data zone host that stores the configuration information, such as client configurations, devices, and scheduling information. The NetWorker server also stores the online NetWorker databases that track the backups and volumes. As a client within the data zone, the NetWorker server automatically backs up the configuration and tracking databases to protect NetWorker data. There is a single NetWorker server per data zone and it must be available for any NetWorker activity to be supported in that data zone. The NetWorker server has the NetWorker client, storage node and server software installed.
Administration of a NetWorker server is performed using the NetWorker Management Console Server (NMC), commonly referred to as the console server. It is a Java-based graphical user interface accessible from any supported web browser. The console server provides a global view of the NetWorker environment, allowing you to centrally configure and manage one or more NetWorker data zones. The console server gathers information about backups from multiple data zones. The console server can prepare a number of preconfigured reports generated using information gathered from any or all of the NetWorker servers. Detailed customized reports can also be created. The NMC server is most often run on the same host as the NetWorker server, however, it can be run on a dedicated host. This is the preferred configuration in larger, busy environments.
The Resource Directory, also known as the resource database, is the directory that contains the configuration resource files.
The Media Database is the NetWorker database used to track the backups and the volumes they are stored on.
Client File Indexes, or CFIs, are the NetWorker databases that track each file or pathname in a client’s backup, allowing clients to browse their backups for files from a particular point in time. The NetWorker server creates and maintains one client file index per client.
Resources are configurable objects used to configure a NetWorker environment.
Each configurable component in NetWorker is represented by a resource and there can be multiple configurations for each type. Examples of resource types include clients, devices, tape libraries, backup start times, and policies.
Nearly all NetWorker resources are stored on and managed by the NetWorker server in the resource
