Unison may be overkill. He could just use zip (or 7za) with the -u (update)
flag to keep a compressed backup of the directory.

ex:
@rem assume a working copy here:
c:\src\work\ProjectA

@rem run periodically (could put into a batch file)
zip -9ru e:\BACKUP\fred\ProjectA.zip c:\src\work\ProjectA

and run that periodically to update the zip. If there are no changes to the
working copy, then the zip file is not updated.

If you're user is using unison to keep two working copies in sync, then he
probably needs to change they way he's using svn.
