Your rsync(1) command is not deleting files on the destination that do 
not exist on the source.  See the various '--delete' options.  You might 
have leftover files or directories on the destination that do not exist 
on the source.


Your du(1) command is displaying disk usage, not apparent size.  See the 
'-A' option.  It is unlikely that UFS and ZFS will use the exact same 
amount of disk space for the same content.
