Something like this.
https://www.amazon.co.uk/WD-TB-Cloud...+my+cloud+home
I have 2 WD NAS Drives (2 & 3TB)
It has shared folders where I put the relavent files I.e Music in the music folder.
On the laptops that access it I create Mapped drives to the folders like this M:\Music, V:\Video
My smart TVs & Blu-Rays can find the shared folders, my android phones and tablets need a different app to see the NAS contents.

I forgot to say that I have set an area in which my laptop puts backed up files automatically.
I also set my mobile to backup videos and pictures to their own folder.
