Actually I think the agent is just the working part of the program.
But I wouldn't know, I never been able to install it. LOL
From the Ghost 15 manual (chapter 9):
The Norton Ghost Agent is the unseen “engine” that does the actual backing up
and restoring of data on a remote computer. Because the Norton Ghost Agent
functions as a service, it does not have a graphical interface.
The Norton Ghost Agent does, however, have a tray icon available from the
Windows system tray to provide feedback of current conditions and to perform
common tasks. For example, you can view backup jobs created for the computer,
reconnect the Norton Ghost Agent, or cancel a task that is currently running.
You can install the agent manually by visiting each computer you want to protect
and install the agent from the product CD. A more efficient method, however, is
to use the Norton Ghost Deploy Agent feature to remotely install the agent on a
computer in the domain whose data you want to protect.
