Might sound daft to you but can I ask for backups of what.
I have checked my icloud and it seems I have never used it. I use Google Drive for virtual storage.
I do have an ipad but have never plugged it into the computer so presume I would have access to icloud from that if I ever wanted it.
I'm just trying to free up space on my laptop really and wondered if there was anything that came with iTunes that was useful I might be using without knowing it.
