Well, that's not what nagios is executing. Your command_line specifies
'-a $ARG2$'. You do not pass an $ARG2$ to the command however so what
nagios is really executing is --

/usr/local/nagios/libexec/check_nrpe -H backuppc.foobar.local -c
check_backuppc -a 

Does _that_ work? I expect that it will fail spectacularly.
