Apple Icloud backup?

So I was signed into my mac and i had my iphone connected to it, and I saw that for my backups it said that "your iphone has never been backed up to icloud" I was wondering whether this is the device itself, or whether it was the account, since I recently changed accounts on the device, so I was wondering if the other account that was on the device had backed things up to icloud, or whether it was the device itself.

The device itself.
