App for backing up Andoid & iPhone contacts,, photos etc to WD

I currently backup my Galaxy S5 to the cloud but would prefer to back up on my NAS *WD EX2)

This would be a great APP if it also worked for the Apple iphone

It is my understanding that backing up this stuff is done by iTunes when you connect your iPhone to computer and iTunes program. So, do this, and then copy that content in iTunes directly to your NAS.
