The standard /CLONE operation deletes extra files in the destination.
To avoid the deletion, you can just say /CLONE /Z0.

Now, if you want to set the Hidden attribute bit (/ASH) to those
files which are not present in the source, you should run a
separate XXCOPY command (probably after the /CLONE /ZO action),

XXCOPY \dst\ \src\ /BB /S /ASH

Here, the order of the original source and destination directories
(\src\ and \dst\ respectively) are reversed so that the /ASH
operation will be acted upon the files in the \dst\.
Now, if you recall my favorite chart,

The /BB switch selects the files that are present in the first
directory but not in the second directory (the opposite of
what what use to be the "extra" files in the destination).
