7 Top Ways to Fix iCloud Backup Failed But I Have Space

What to do when iCloud not backing up even with enough storage

iCloud is a cloud server commonly used by Apple users, which is used to store private data. Sometimes we may encounter some iCloud issues when backup data. The most common problem we encounter is iCloud storage full, and we can solve it by freeing up space. 

But sometimes why iPhone won't backup even though iCloud has enough storage? The next content will be the causes and reasons for iCloud backup failures with enough space and introduce another two great backup utilities for iPhone: iTunes and AOMEI FoneBackup.

Part 1. 5 methods to fix iCloud not backing up with enough storage

In the following part, there are 5  methods below to help you figure out about iCloud not backing up with enough storage.

Method 1. Charge your phone with enough power

iCloud backup is relatively power-hungry, so backup requires enough power on the phone( more than 50%). There is a battery icon in the upper-right corner of your iPhone where you can check the battery level. If the phone battery is low, please charge it in time.

Method 2. Check your Internet

iCloud backup can only be performed under the condition of a stable network, so you ought to check your Internet. If you use cellular data, I suggest you switch to WIFI because it’s more stable than the former.

You can quickly open the Control Center (swipe down from the upper-right corner or swipe up from the bottom of the screen), and convert the network connection.

If your network condition is good but your iPhone still fails to back up, you could go to iPhone Settings > General > Reset > Choose Reset Network Settings to fix.

After resetting the network, you shouldconnect to WIFIagain.

Method 3. Turn off and on iCloud Backup

iCloud settings can also cause backup problems. You can fix the problem by restarting your iCloud Backup.

Step 1. Open the iPhone Settings, and then tap your name.

Step 2. Click iCloud and tap iCloud Backup.

Step 3. Switch off and on iCloud Backup.

Step 4. Tap on Back Up Now.

Method 4. Re-login to your iCloud account

Another simple way to fix iCloud is to log back into iCloud. This is a quick fix if the iCloud is faulty.

Go to Settings > Tap your name > Slide down and click Sign Out > Enter your Apple ID to sign in.

Method 5. Contact Apple Support

If you use the above methods and your iCloud backup still fails, you can contact Apple Support via the official website. They know their products better, so they can bring you a more effective solution.

Part 2. Backup iPhone with iTunes

You can utilize iTunes on your PC to back up your data as well. Compared with iCloud, iTunes is more complete on backup because iCloud has limited storage space.

Step 1. Download iTunes on the computer, and connect your iPhone to the computer.

Step 2. Click the device icon in the upper-left corner.

Step 3. Tap Summary, and click Back Up Now.

Part 3. Using AOMEI FoneBackup to backup your iPhone
