I am clearly missing some with iCloud storage, every few weeks I get an email saying my storage is nearly full and I only have a couple of hundred MB left. So I am always deleting my back up and letting it back up overnight. When I back it up it's only about 3GB. Why is it consistently over the weeks always full? I have no apps being backed up to it either, they're all off. So how do I stop this and what is causing it?
Here is an example of what I mean. It backed up yesterday. I have all the apps off and it wants to back up another 192MB. I haven't sent s load of images in iMessage or anything like this in the last day so I don't know where the data is coming from. I don't take many photos anyway so it's not photos. Unless it has anything to do with Apple Watch? I can't see or find anything about activity app being backed up the cloud, but that's the only thing left I can think of
