So yes you also need to install itunes to backup on your computer, because why directly mount it as a usb drive without an apple app?
That would also need zero effort from apple, but I was talking about an online backup with since forever established protocols.
"I can't back it up completely" and "I can't back it up completely the way I want to" are two different arguments. It's fine if the second is the argument you actually want to make, just be clear you're making it.
