- Question from Apple Community
iCloud is a built-in tool on iPhone. You could easily find it in iPhone Settings to backup iPhone data or the whole iPhone to the cloud. You could sync iPhone data on another Apple device with iCloud or restore iPhone when you set up it. However, there are chances that you are notified that your iCloud backup failed or encounter such issue "This iPhone cannot be backed up because there is not enough iCloud storage available."
There are two possibilities for receiving this message, one is that you have run out of your iCloud storage, and the other is that there is a mismatch in how Apple accounts for and reports on what is stored in your iCloud account. No matter what situation you are in, here in this guide, you can find a way out.
Every user could have 5GB of free iCloud storage. How can you solve the problem when iCloud storage is not enough? You should delete unneeded data on iCloud or reduce iPhone backup size.
#1 Deleting iCloud photos: iPhone photos could eat much iCloud storage for their high quality. You could not view iCloud photos on iPhone but there’s another way to view or delete them.
Go to the site of iCloud and sign in with your Apple ID > Click the icon of Photos > Press Ctrl and select pictures as many as you want to delete them.
The best way to clear iCloud storage is backing up iPhone photos to computer and then delete all the iCloud photos.
#2 Deleting other iCloud data: Even though you could not view the specific files in the cloud, you could view and delete the whole folder on iPhone.
Step 1. Go to iPhone Settings > [your name] > iCloud > Manage Storage.
Step 2. Delete the files you want, especially the old backup to release iCloud storage. You could see all the iCloud data and how much storage they have occupied.
#3 Check iCloud backup size: Except for clear iCloud storage, you could also reduce the content of iPhone backup.
Step 1. Go to Manage Storage > Backups > Tap the name of your device. You could find the device name there even though you haven’t backed up your iPhone with iCloud.
Step 2. Uncheck the apps you don’t want to backup
You could see when you backup iPhone with iCloud last time and the estimated backup size this time. How much storage that the app data is going to take is shown.
In most cases, even if you receive the notice that iPhone cannot be backed up because there is not enough storage, you still have space available in your iCloud account. If you are confident with your available iCloud storage space, try solutions in this part to troubleshoot the issue.
#1 Check iOS System Status: Sometimes Apple is maintaining or upgrading iOS service, so iCloud might give you wrong clue. You could check iOS System Status to see whether the issue is being temporarily open. You could wait until the issue is closed or contact Apple support to consult.
#2 Check for iOS update: Make sure your device is running the most recent version of iOS. Apple will repair some problems in your system and iCloud with each new release. Just go to Settings > General > Software Update to update to the newest version.
#3 Check iCloud sync settings: Ensure that any iCloud-enabled apps and services are correctly synced and are not taking up unnecessary space. If you do not want certain apps or data to be synchronized to iCloud and use up iCloud storage, you can disable backup for these apps in the iCloud storage management window shown in the first method.
#4 Sign out and in iCloud: Signing out and then logging in iCloud again on your iPhone can refresh the iCloud backup service, which can occasionally help with syncing issues and storage errors. To achieve this, go to Settings > your profile > Scroll down to the bottom and tap Sign Out.
#5 Contact Apple Support: If none of the above steps resolve the issue, you may need to contact Apple support for further assistance. They can help you troubleshoot the issue and may be able to offer additional solutions. Optionally, you can head to the next part to look for an iCloud alternative to manually backup iPhone to iCloud or computer.
