I have 25gb of storage on my iCloud account as I use an iPad and iPhone 6. Less than a quarter of it is full. My kids both have iPod touches and each only have the free 5gb of storage on their iCloud and they're both full so there is no more room to store stuff. Instead of me paying to upgrade their iCloud storage on their devices, is there any way I can back up their devices so that it saves to my iCloud storage? Is just a simple of case of signing into my iCloud storage account within the settings on their iPod touches?
