NetWorker Services
NetWorker Server Processes
| Process | Function |
| nsrctld | The top-level NetWorker Server process that monitors, stops, and starts all NetWorker Server processes. |
| nsrd |
|
| nsrjobd | Monitors NetWorker activity during a backup or recovery operation. |
| nsrindexd | Provides an indexing service to read, write, and remove client file index (CFI) entries. The nsrd service starts on the nsrindexd process on the NetWorker server. The nsrindexd process spawns an additional helper nsrindexd process for each index session. NetWorker uses index sessions to read, write, or delete index entries. For example, when a user performs a file-level or browsable recover. When the read or write operation completes, the helper nsrindexd process closes. |
| nsrmmgd |
|
| nsrlogd | Supports the NetWorker audit log service, which is configured to run on the NetWorker server by default. |
| nsrcpd |
|
| nsrdispd | Handles RPC-based calls for the nsrd process, from remote or third-party processes. |
| nsrdisp_nwbg | Started by nsrdispd to handle NMC server requests for information from RAP and media databases on the NetWorker server. |
| nsrdisp_vproxy | Started by nsrdispd to handle RPC-based calls between NetWorker server and vProxy appliance. |
| nsrdisp_dd | Started by nsrdispd to handle RPC-based calls between NetWorker server and Data Domain (DD). |
| nsrlmc |
|
| nsrvmwsd | Provides a web service to manage VMware VM backups that are part of the NetWorker VMware protection feature. |
| Tomcat | Tomcat web server instance for the NetWorker authentication (authc) service |
| nsrexecd |
|
NetWorker Storage Node
| Process | Function |
| nsrmmd |
|
| nsrsnmd |
|
| nsrlcpd |
|
| nsrexecd | Authenticates and processes the NetWorker Server remote execution (nsrexec) requests and runs the save and savefs programs on the client. |
NOTE: Every NetWorker server has an embedded NetWorker storage node, the above processes may be found running on the NetWorker server where applicable.
NetWorker Management Console (NMC) Server
| Process | Function |
| nsrexecd | Authenticates and processes the NetWorker Server remote execution (nsrexec) requests and runs the save and savefs programs on the client. |
| gstd | Known as the Generic Services Toolkit (GST), controls other services that are provided by the NMC Server. |
| httpd | Starts the NMC Console user interface on the client through a web browser. |
| postgres | A database server that manages information pertaining to NMC Server Management. For example, Console reports. |
| gstsnmptrapd |
|
NetWorker Client:
- nsrexecd - Authenticates with NetWorker server andmanages requests from the NetWorker server to start the save and savefs processes to support backup requests.
NetWorker Web User Interface (NWUI) Server:
- nwuictld -Interacts with nwui postgres processes and database.
Starting and Stopping Services:
NetWorker services can be managed from the command-line on both Linux and Windows systems. Microsoft Windows systems can also manage NetWorker services from the Services.msc console.
Linux:

Ports
NetWorker Service Ports:
- 7937, 7938 - Fixed ports. Each NetWorker host uses these ports to start communication.
- 7937 - 9936 - Variable ports. NetWorker dynamically opens ports. A NetWorker host can allocate any port that is defined in this port range at random. This is the default recommended range, but it can be narrowed or expanded.
