the RsyncP man page tells me this: http://search.cpan.org/~cbarratt/File-RsyncP-0.68/lib/File/RsyncP.pm File::RsyncP does not compute file deltas (ie: it behaves as though --whole-file is specified) or implement exclude or include options when sending file. File::RsyncP does handle file deltas and exclude and include options when receiving files. Thus no need to try the --whole-file option.
