Last Backup Could not be Completed

Backing up your iOS device regularly is very important. However, many users who updated to iOS 9 have reportedly noticed that when they try to backup via iCloud, the backup would abruptly stop after a while and would display an error saying the last backup could not be completed. It seems that a simple reboot or several tries do not solve this problem. However, there are some steps that you can take to fix this error.

How to Fix iCloud Backup Error :

Before trying any of the following methods, please make sure that you do have enough storage in your iCloud for the backup. Also, try rebooting your device. In case this does not solve the problem, then try one of the following methods.

1. Backup via iTunes :

itunes backup ios 9

If iCloud backup is not working, then it is better to backup your device using iTunes before following any other methods. You don’t want to lose your data, right ? Once an iTunes backup is made, you can then go ahead and try solving the iCloud backup error with the next solutions.

2. Sign Out of iCloud and Sign In Again :

It is possible that the problem might be caused by caching in Apple servers. So you can try logging out and then log in again to see if it solves the error. To do this, go to Settings > iCloud Sign Out. Doing this will delete all the cards that you have saved with Apple Pay, but it is worth trying.sign-out-of-iCloud (1)

Now login again and see if you can backup via iCloud. If not, move on to the next one.

3. Reset Network Settings :

Go to Settings > General > Reset > Reset Network Settings. You will need to enter your password to confirm the action and reset the settings. Now your WiFi networks will be wiped and you will have to start fresh. reset iphone 6 ios 8 network settings

4. Change the Wi-Fi network :

It is quite possible that the WiFi network you are using might be having some problems and might not be connecting the internet properly. Try using your friend’s or neighbour’s WiFi to see if that is the case. ios_9_wifi_networks

5. Delete the Existing iCloud Backup :

This is the method that has solved the problem for many people. Seems like the existing backup caused the issue to crop up.  Go to Settings > iCloud > Storage > Manage Storage. Now choose your iOS device that is giving you the backup error and select the Delete Backup option at the bottom.Delete-iCloud-backup (1)


Many users reported that they were not able to delete the backup from that device, but they managed to delete the backup of that device from another iOS device that is connected to the same iCloud account. In case you have several iOS devices, then use another device than the problematic one and browse to Settings > iCloud > Storage > Manage Storage. Now delete the problematic iCloud backup.

6. Restore Your Device :

In case none of the above methods work for you, then it is suggested that you restore your iOS device, which resolves 99.99% errors. Go to Settings > General > Reset > Erase All Content and Settings.
