good idea - problem we have is that the macbook currently runs off an external 
SSD drive , connected by one the 2 USB ports.  I ned to get my 4 USB Port thing 
connected tot the macbook to connect all these things together - didn’t have 
time yesterday. 

I remembered that I had some iPhone software called imazing https://imazing.com
so  connected both  external backup drive  and iPhone 7 to the macpro USB 
ports, then used iAmazing 2  ( which we have a license for)   to backup  iphone 
to the external hard drive.

will do for now.

thanks  for the suggestion about moving the photos database to a different 
drive - I recently did this on my macpro when I upgraded to El Capitan - i.e. 
el capitan on SSD boot drive, data on a separate hardisk.
