Best back up, photo use, iTunes and more for MAC

Hi,

Hoping for some advice. I’ve set up my MyCloud and have messed around with folders and settings to get use to things but having a few issues;

  • I want to place ‘Photos’ directly on to the MyCloud as my MacAir is short of space. I’m finding this a bit of an issue with lots of random folders being shown when i view through the mobile app and when i open on the Air it takes a good amount of time to load. What the best set up for this?

  • I want to do the same for ‘itunes’ 

  • In general i want to stream itunes to my Sonos, play some movies via a Playstation and back up 3 computers.

I hope you can poit me in the right direction.

Thanks in advance.
