NSRD(8)
NAME
nsrd − daemon providing the NetWorker service
SYNOPSIS
nsrd
ansrd [ commentary ]
DESCRIPTION
The nsrd daemon provides an RPC-based save and recover service. This service allows users to save, query for, and recover their files across a network. The RPC program number provided by nsrd is 390103.
Normally nsrd is invoked from a startup shell script (for example rc.local, rc.boot) at boot-time, and should never need to be started directly by a user. After it is started, nsrd starts up the other daemons it needs to provide the NetWorker service.
The nsrd command must be run on a machine with appropriate resources. These resources include such things as devices (e.g. tape drives) which are under the control of the media multiplexor software, nsrmmd(8), and sufficient disk space for the index daemons, nsrindexd(8), and nsrmmdbd(8), to maintain the index of user files that have been saved and which volumes contain which files.
Each time a backup, recover or various other sessions begin, nsrd starts another program, ansrd, to process the requested session. The ansrd program is called an agent. The agent is in charge of monitoring that backup, recover, or other session, and automatically exits when a session completes. Using ps(8) or another process monitoring tool, one can inspect the subsequent parameters of ansrd to see what kind of session it is monitoring. If necessary, agents can be forcibly terminated to abort a backup or recover session. Agents cannot be run directly; they can only be started by nsrd.
