That's what I thought, too, but it doesn't appear to work that way.

In the same way.  You have $filename and ._$filename for each file that 
has a resource fork.  Apple refers to these pairs as "AppleDouble 
files".  If you work with files over SMB (and presumably NFS), you get 
these same double files.  The Finder, of course, won't show these 
resource files, but ls will.  I also doubt that cp/tar/cpio will 
properly copy the resource forks from files that aren't AppleDoubled, 
which is why ditto exists.

FWIW, my backup/restore went well, so it looks like ditto did its job.
