iCloud backup
I deleted the backups in my iCloud to create more storage and it now will not let me backup to my iCloud because it says there is not enough storage but there is plenty. How do I get this phone to backup to the iCloud?
iPhone 7, iOS 13
It is possible that the size of your backup could exceed your available storage. You dint say how much iCloud storage you currently have. If you only have the 5GB of free storage, that can easily be used up in no time depending on what you backup with iCloud.
Maybe something in here will help as well.
If you can't back up to iCloud or restore from iCloud backup failed - Apple Support
