The only time I use dd is when I have evidence that the file system
is unsuccessfully fsck'd, in which case I know that I will be reading
tea leaves and tossing chick'n bones.  Other than that, if the fs is
known clean, then cp -a provides a distinct advantage.  3 or 4 times 
have been the former, and all of the many others have been the later.
