I do not think the OP was asking a question, they appeared to be trying
to show how to use rsync between two NAS devices. 

The use of '--numeric-ids' was interesting, as anyone that runs two or
more Samba AD DCs will know, you cannot rely on a user or group ID
being the same on multiple computers, unless they are domain members.

I do have one question though.

If I wanted to make all the shared folders on the old Synology NAS read only,
can I run the following command?

mount -o remount,ro /volume1

Verify:

mount | grep volume1

You should see (ro,?).

After I am done with rsync, I will run the following command to restore
read-write:

mount -o remount,rw /volume1

Will the above commands work on a Synology NAS with DSM 7.1.1? The old NAS is
DS713+.

Thank you.
