I haven't tested this, but I believe the order is to source the main config
file and then source the config file for the individual host being backed up
So you should be able to do something like this:
$Conf{RsyncArgs} = [ @$Conf{RsyncArgs}, '--copy-links' ];
Since you're dealing with Perl, you could probably create a file with a list
of slow hosts, read that into a hash (say, %slow_hosts, since I don't like
CamelCase)), and then you can say:
$Conf{RsyncArgs} = [ @$RConf{RsyncArgs}, '--bwlimit=128' ] if defined
$slow_hosts{$host};
