I was thinking to use the whole-file option instead of letting it attempt to
chew through the files for diffs, as I had problems with rsync dealing with 
files in the 12-15gb range in the past, though it worked great when using 
--whole-file.  Would there be a more efficient program to use for just moving 
the bits over there?
