That looks backwards to me, presuming you have sparse files?
Although "man du" is, frankly, vague about what this means, I'd imagine from 
the description that it tallies the byte sizes of the files; du normally 
tallies "blocks" from the st_blocks stat field, which reports allocated blocks 
(which is lower than st_size/st_blksize if the file is sparse).

So how you get a smaller "du" with --apparent-size escapes me. You are duing 
the same directory, yes? Not the source and copied directories?

I'm still wondering if you do have sparse files; images generally are not.
