If an alert says that there's not enough iCloud storage
Check how much iCloud storage you have available, then check your Next Backup Size. Then take steps to reduce the amount of information you store in iCloud, or upgrade your iCloud storage.
Check your iCloud storage and Next Backup Size in iOS or iPadOS
- Go to Settings > [your name].
- Tap iCloud. The amount of iCloud storage that you've used is listed at the top. Learn more.
- Tap Manage Storage.
- Tap Backups, then tap the device you're using. Next Backup Size is listed under Last Backup and Backup Size.
It may take a few minutes for your device to calculate Next Backup Size.
If a message says that your last backup couldn't be completed
