Creating an iCloud backup is usually an afterthought since most people have their iCloud backups set to automatic. So, unless something goes wrong, your iCloud backup remains a worry free zone. But when something does go wrong, like seeing the, “last backup could not be completed” error, it can seem like a really big deal. Back ups are only really relevant when they are needed, so not being able to complete a backup can be distressing. But luckily, the solutions are pretty simple ones. 

How to fix “the last backup could not be completed” iCloud Error

When it comes to system errors like this, there are a few tried and true actions you can always try before you really need to panic. Before you try the following methods, make sure to try to back up your device to iTunes just to be on the safe side.

1. Reboot Your Device 

Just like with most electronic devices – if it’s not working, turn it off and try again. But this is not going to be a normal reboot. Instead of holding the Sleep/Wake button and sliding to power off, you are going to hold the Sleep/Wake button and the Home button simultaneously until your device is forced to reboot. Keep holding both buttons (for around 8 seconds) until you see the Apple boot logo. Then release the buttons and let the device turn on like it normally would.

Hopefully, when you go back to Settings -> iCloud and back up your device, you no longer see that error message. If you still do see that messages, read on.

2. Log Out of iCloud

Another quick fix could be simply logging out of your iCloud account then logging back in. Settings -> iCloud and find Sign Out at the bottom of the menu.

3. Reset Network Settings

Some folks have had success fixing the backup error by following these steps. Go to Settings -> General -> Reset -> Reset Network Settings. When you reset your network settings you’ll be turning everything back to factory default. So, the next time you use your phone you’ll need to reenter any network passwords or settings.

4. Delete Older Backups

To delete an older backup, head to Settings -> iCloud -> Storage -> Manage Storage and select the backup or backups that you’d like to remove. There will be multiple backups there if you have more than one device, so make sure to delete the backups on the device that you are having the backup error on.

5. Update Your Device

If you have been holding on to earlier iOS versions, now might be the time to try the latest version. Sticking with older iterations of operating systems does have its benefits, but the lack of support and attention from developers can lead to issues down the road. If none of the above suggestions have worked for you, this might be the next best option. Head over to Settings -> General -> Software Update to get going.
