xfs_copy knows about the xfs format, so it only copies what it needs to.  dd 
will copy every bit on the source disk.  So, xfs_copy is more efficient.  There 
is no option to copy individual files.
Depending on the problem with your original filesystem, perhaps xfs_copy might 
not be the best choice.
