Preprocess your files with tar: Create a tar archive without
compression, it will preserve the file names. Just make sure
the tar archive itself does not contain "forbidden" characters
or names. :-)

If I understand correctly, you're not going to _use_ the files
on the "Windows" PC, right? In this case, you don't have to
worry about the fact that "Windows" is missing basic means for
archive processing.

You could maybe install Cygnwin or Mingw or something like that
on the "Windows" box to postprocess the tar archive after it
has successfully arrived, changing the timestamps with a
replacement command like "sed 's/:/./g'". The archive would
then be extracted and its _content_ can be accessed on "Windows"
too. The replacement run could simply eliminate all "offendig"
characters or strings for _all_ files in the archive.

Of course, you could do this kind of processing _before_ the
rsync run on the FreeBSD machine, which will probably be a lot
easier, and you don't have to involve tar archiving.

So much for interoperability on "Windows". ;-)
