How to Fix Unable to Backup iPhone on iCloud

The key is to make sure the network is working well and there is enough iCloud storage space. Otherwise, the iCloud backup will fail.

Solution 1. Connect iPhone to A Secure and Fast Wi-Fi

When you use iCloud to backup iPhone, the Internet is the main factor to decide whether you could successfully backup your iPhone.

● Connect iPhone to a fast Wi-Fi: A fast Wi-Fi could let iPhone stably transfer the data. If your network is slow or your iPhone disconnected from the Internet several times during the backup progress, your iCloud backup would fail.
● Connect iPhone to a secure Wi-Fi: iOS is famous for caring about users' privacy, so if you connect iPhone to a public Wi-Fi, iOS would stop transferring the data.

Turn on Wifi iPhone

Solution 2. Clear iCloud Storage and Check iCloud Backup Size

You have just 5GB of free iCloud storage. If your iCloud storage is full and you are unable to backup iPhone to iCloud, you should clear the unneeded data in iCloud or reduce the content you are going to backup, or you need to pay for changing iCloud storage plan.

● Clear iCloud storage: Go to iPhone Settings > [your name] >iCloud > Manage Storage to check the status of iCloud storage. iCloud photos and old iCloud backups usually eat a large amount of iCloud storage. If you have some useful data, you could download iCloud backup to PC before deleting them.
● Check iCloud backup size: iCloud would save iPhone settings and app data to your backup, but you don’t need to save them all. You could go to iCloud > Manage Storage > Backups > [device name] to uncheck the app that you don’t need to save.

Solution 3. Enable iCloud Backup via iTunes

Sometimes you would find iCloud Backup button greyed out in iPhone Settings, so you can’t backup iPhone to iCloud by tapping Back Up Now. This could be caused by an insecure Internet connection or system bug. Except for connecting iPhone to good Wi-Fi, you could switch on the button in iTunes.

● Switch on iCloud Backup button in iTunes: You need to open iTunes on PC or Mac > connect iPhone to iTunes with USB cable > click the device icon in the upper-left corner > check iCloud in Backups > click Sync and you would find that iCloud Backup has been switched on.

How to Fix Unable to Backup iPhone to iTunes

Make sure that you have installed the latest version of iTunes on computer. iTunes downloaded from Microsoft Store is usually updated automatically when a new version is released. If you downloaded iTunes from Apple's website, you can open iTunes > click Help > choose Check for Updates to get the latest version.

Solution 1. Fix iTunes Connection Issues

If you can’t backup iPhone to iTunes, the first step is to fix the connection issues to let iTunes read your iPhone.

● Check USB cable and USB port: The physical connection should be established. You should use a lightning cable to connect iPhone to PC or Mac and make sure the USB port is not broken or loose.
Disable firewall and antivirus: Your iPhone might be wrongly recognized as a threat to your PC or Mac, so you could disable firewall and antivirus during backup progress.
● Update Driver: Apple Mobile Device USB driver is necessary to connect iPhone to PC. You need to connect the iPhone to PC > click the Start Button on desktop > select Device Manager > expand Potable Devices > right click your device > click Update driver > select Search automatically for updated driver software. After that, your iTunes would recognize your iPhone.

Solution 2. Change iTunes Backup Location

iTunes would always create iPhone backup in your C Drive, so if you don't have enough space in C Drive, you are unable to backup iPhone to iTunes. However, you could use Windows command to change iTunes backup location.

Step 1. You iTunes backup is saved in C:\Users\[PC name]\AppData\Roaming\Apple Computer\ MobileSync. You need to copy the folder Backup to another location like D Drive.
Step 2. Press Windows + R, input “cmd” in the box and press Enter.
Step 3. Enter mklink /J “C:\Users\[PC name]\AppData\Roaming\Apple Computer\MobileSync\Backup” “D:\MobileSync” (the target destination is up to you)and pressEnter.

Cmd Change iTunes Backup Location

Solution 3. Clear Old iTunes Backup and Encrypt This Backup

iTunes backup would be affected by the old backups. The incompatibility might let you fail to create an iPhone backup.

● Clear old backup: Except for going to C Drive to delete the old backups, you could directly delete them in iTunes. Open iTunes > click Edit > select Preferences > select Devices and you could select the old backups and delete them.
● Encrypt this backup: If your last iPhone backup is encrypted, this backup should be encrypted, too. Check Encrypt local backup before you click Back Up Now.
