224 NetBackup Troubleshooting Guide - UNIX
Startup Process
Before NetBackup can perform scheduled operations or respond to user-directed requests,
the NetBackup request daemon bprd must be started on the master server, and the Media
Manager device daemon ltid must be started on the master server and all media servers.
These two daemons, in turn, automatically start other daemons and programs as
necessary (see Figure 7).
On a media server, it is not necessary to start bprd because it is not used. NetBackup
automatically starts other required NetBackup programs when it accesses the media
server.
Another daemon that executes on all server and clients is the NetBackup client daemon,
bpcd. On UNIX clients, inetd starts bpcd automatically so no special actions are
required. On Windows NT clients, bpinetd performs the same functions as inetd.
Other PC clients do not use inetd or bpinetd but are usually configured to start bpcd
automatically (see their user’s guides for instructions).
There are no other daemons or programs that you must explicitly start. The necessary
programs are started automatically during the backup or restore operation.
Figure 7 shows the programs that must be running and how they are started. The Media
Manager functional description, later in this appendix, has details on the actions started
by ltid.
