iCloud used as backup tool .. Not synchronization, doable?
I want to use iCloud for backup of my photo library ONLY without synchronization. Got 40k photos on my MacBook Pro and not interested in pushing them down to my iPhone (not even as thumbnails in optimized mode) .. so if I enable iCloud on my MAC -in Photos- and disable it on my my iOS device that should do it, right ?
Now I got 4 Photos libraries, but I understand I can only use iCloud with one (being the system library) .. can I enable iCloud for each one at a time (assign system library for each one at a time) ?
Thanks for any help ..
MacBook Pro (13-inch Mid 2012), OS X El Capitan (10.11)
