Are you getting the iCloud backup failed error on iPhone? In this guide, I am going to explain to you how to fix this issue on your device. iCloud always comes in handy to take a platformless backup of your important data. iPhones, by default, do not come with too much native storage.

However, almost all iPhone users tend to run out of storage on their iPhones due to storing high-resolution photos, videos, and other forms of media. So, taking an iCloud backup becomes necessary to avoid the issue of storage unavailability.

iCloud Backup Failed

The iCloud backup failed error may show due to various issues. I have listed them below.

Why Are You Getting the iCloud Backup Failed Error on iOS?

  • A slow internet connection may be causing hindrance and not allowing iOS to upload the data to the cloud.
  • It may be a bug on the iOS build that is causing the iCloud backup failed error.
  • iCloud storage space has been claimed, and there is no space to store new backup data.
  • The iCloud backup may be disabled on the iPhone.

Now, let us troubleshoot this error and enable iCloud backup on the iPhone.

Fix 1. Restart your iPhone

If you think you were able to take backup until now, and this is the first time this is happening, you can simply reboot your iPhone. Often I face the issue as well, and a restart fixes everything.

  1. Press the power button of the iPhone.
  2. On the next screen, tap and move the slider when you see Slide to Power Off.

  3. After a few seconds, restart the iPhone.

  1. Open the Settings.
  2. Tap on the Apple ID profile.

  4. Once the sign-in page shows up, enter your Apple ID and password to sign in.

Now, go to iCloud and try to create a backup. Check if the error message is still showing.

Fix 3. Clear Storage on iCloud

Apple provides a free storage space of 5GB. Once that space is filled up, you need to clear the iCloud storage to store the next batch of data from the iPhone as a backup. Otherwise, you can buy more iCloud storage space.

First, you need to check how much storage space on iCloud is available.

  1. Go to Settings.
  2. Tap on Apple ID.
  3. Then tap on iCloud.
    iCloud Option iPhone Settings
  4. Under that, you can check storage distribution for various apps which have a current backup stored on iCloud.
  5. Then tap on Manage Storage.

If you want to buy more storage, tap on Change Storage Plan.

Fix 4. Check Your Internet Connection

Router Reboot Internet

If you get ‘The Last Backup Could Not Be Completed‘ error, the culprit is often your Wi-Fi connection. Make sure that your iPhone is connected to Wi-Fi; the iCloud Backup process is not completely dependent on a cellular data connection. The backup process may get affected if your internet connection is too slow. Normally, when there are several media files of high resolution and the internet is slow, then it will be tough to create an iCloud backup.

Either the process will be too slow, or you end up seeing the iCloud backup failed error. You can switch to a network with better speed or fix your current network. The ISP may be carrying out maintenance for which the network may be down for a while. You can even contact the customer support of your ISP.

Fix 5. Disable Low Power Mode and Low Data Mode

Few apps are restricted from running in the background when the low battery mode or Low Data Mode is turned on. To keep the iPhone backup to iCloud, you need to disable Low Power Mode and Data Mode. Here is how you can do it:

  • Open Settings > Battery.
  • Switch off Low Power Mode.

How to Disable Low Data Mode?

Open Settings → Click on Mobile Data → Tap on Mobile Data Options→ Turn Off Low Data Mode Toggle.

Fix 6. Reset All Settings

You may also try to reset the settings of the iPhone if none of the above troubleshooting methods are able to solve the error.

  1. Go to Settings > General.
  2. Then tap on transfer or Reset iPhone.
    Transfer or Reset iPhone
  3. Next, tap on Reset.
    reset iPhone
  4. From the menu, select Reset All Settings.
    reset all settings
  5. Enter the passcode to proceed.

After you reset, the device will most likely reboot. Once that iPhone restarts, try to resume the iCloud backup, and you should be able to create a backup without the iCloud backup failed error showing up.

Fix 7. Update iOS

To eliminate the possibility of bugs causing the iCloud backup failed error, you may also upgrade to the latest build of iOS.

  1. Launch the Settings app.
  2. Next, tap on General.
    General Settings
  3. Then tap on Software Update.

Fix 8. Apple Server Maybe Down

While it is not very usual to see Apple servers go down, you can check the system status page of Apple. If iCloud services have any issue, that will be denoted by a red dot. If every service is working fine, then the same will be denoted by a green dot.

Check iCloud Services

  • Go to the Apple System Status page.
  • Check the status of iCloud services.

As of this writing, there is no issue with any iCloud service provided by Apple. Check the screenshot below.

Fix 9. Check if iCloud Backup is Enabled
