Maintenance Commands nsrd ( 1m )
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. Required
resources include both devices, such as tape drives, and sufficient disk space for the
index daemons, (see nsrindexd(1m) and nsrmmdbd(1m)). The devices are controlled
by multiplexor software (see nsrmmd(1m)), and the disk space is used to maintain the
index of saved user files and volumes with corresponding files.
Each time a backup, recover, or another session begins, nsrd starts the 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 another session, and automatically
exits when a session completes. Using ps(1) or another process monitoring tool, you
can inspect the subsequent parameters of ansrd to see what kind of session it is moni-
toring. 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.
