Saving music and movies downloaded to iPhone iCloud.

[iRun26.2]

I have many CDs of music I put into my iPhone. I also have several DVDs of TV shows I own that I ripped and put into my iPhone.

I can’t figure out how to save them (back them up) in my iCloud account. Is that possible?

 

[now i see it]

They need to initially be stored in a app that has access to iCloud. Then its s simple matter of uploading them to iCloud Drive or iCloud.
I've got a few DVDs I've rippied that I uploaded to iCloud Drive. It doesn't make for a very good media player though.
