You need a comma instead of a period. Otherwise it should work.

The behavior depends upon the XferMethod, which is tar in your
case. $Conf{BackupFilesOnly} is a set of directories to backup.
Each entry of $Conf{BackupFilesExclude} is sent to tar with the
--exclude option. This provides a set of regular expressions that
are applied to any file to see if it matches, and therefore should
be skipped. Therefore, $Conf{BackupFilesExclude} applies equally
to every directory in $Conf{BackupFilesOnly}. So I don't think
you can accomplish what you want with tar.
The only alternative I can think of is to split the top-level
directories into seperate "shares" (ie: put them in $Conf{TarShareName}
instead of $Conf{BackupFilesOnly}), and then use share-specific
settings in $Conf{BackupFilesExclude}. The causes a different
transfer (ie: tar) to be done for each "share".
Rsync allows richer exclude/include options, and by adding the
right --include and --exclude options to the RsyncClientCmd you
should be able to include just .o files below /lib/modules and
exclude all the others.
