Flags for silent install of backup client

I need to install the backup client silently on systems and specify FileBackupChoice as UserFiles. Currently when I run the client by default it is installing for allwithoutsystem. Is there a command line switch available to perform this? I am trying to avoid users going through the setup wizard.
Thank you

No command line switch for the installer for this.

I guess what usually is done in this situation is disabling client side changing of settings, then set the directories to backup on the server (+ the excludes).

OK and that is what I was thinking. Just to be clear, I just want the contents of c:\users, can I safely exclude c:* and then include the users directory? I presume include has priority over exclude. Thank you for the quick response.
