Preferred Digital Music File Backup?

Sending a physical device to restore is needed. Who does that?

That is a service offered by iDrive. The company will also send you a drive to load your files onto, saving you the burden of dealing with slow uploads.

I back up to external HD and iDrive and have been happy with their service.

I back up to a solid state drive on my computer which is only for music back up.  I also have a USB hard drive I back up the music files on.  I have 2 different back ups.  I did this because I lost all my files once with no back up and spent the next year re-ripping all my cd's.

A little off-subject, and totally optimistic, but I feel our tech overlords should offer lifetime streaming of any album on CD we have purchased.
We would send the CD to "them" and have permanent streaming rights.

"They" want to discontinue physical media forever and this would encourage people enter the streaming world. Once you are "on board" with streaming, any new purchases would be virtual. I have yet to stream as it seems to me like a gooey mess that I can't understand and have no reason to try. C'mon fat cats, give me a reason to switch.

Both. An external hard drive at home and crashplan in the cloud. 

Dweller,

GooglePlay music does exactly what you describe but unfortunately compressed for now.
