iCloud backup won’t complete


Topic starter

Hello folks,

i just upgraded my iPad 2018 to a 10.5” iPad Pro.  I have been using iCloud to backup and restore all my iOS devices for the past year, and so far it has been working pretty nicely. Very easy to restore an old backup on a new purchase. I have PLENTY of free iCloud space on my plan  

However, I’m wracking my brains on this one. For some reason, I can’t seem to complete an iCloud backup for this device. I get a message that “some files were unavailable during the last backup”. 

I have tried deleting  the incomplete backup, tried signing out and signing back in to iCloud, I’ve tried renaming the device. I’ve tried both manually backing up using the “backup now” button, as well as leaving the iPad Pro over night with power on and locked. It simply never completes.  

i have made a local backup using imazing, but I would like to have iCloud backups working reliably. 

has anyone seen this behavior, and know of a fix? 

it is not a bad idea to check in with Apple Support as there are going to be times when they can think of things to try that others may not.

I would try the fixes found here:

It looks like deleting the last backup should solve the problem.

Deleting last backup did not solve the problem. Neither did logging out and logging back into iCloud. I wound up contacting apple tech support. They suggested resetting the device. After that the backup took several hours and did complete. However, the original backup was deleted from iCloud and I wound up losing a few things - but  I was lucky this time that I didn’t have to nuke and pave..

As John and Dave have mentioned many times in the past. Don’t rely only on iCloud to back things up. Have a local backup as well.

Happy clouding 


Thanks for the update. Glad you got your problem resolved. When in doubt, it is not a bad idea to check in with Apple Support as there are going to be times when they can think of things to try that others may not. 


I don’t mean to trivialise your troubleshooting steps so far, but just in case & because you haven’t explicitly mentioned it, have you done a full turn off & turn on (ToTo) of the iPad? I say this because it sounds like the backup is trying to use a file, or files, that are “locked”.

But I also wonder if iCloud is somehow getting confused by the fact this is a “restored” device and is being adversely affected by backups done for the previous iPad? Do iCloud backups still exist for that device?

yes I have power cycled the device, I’ve tried power cycling signed out of iCloud, then signing in.  Also tried closing all open apps. 

Something is confused alright. Im going to try apple support now


Well, it seems that you have tried all the possible methods. Are you now able to re-use iCloud for backup? I am so happy to hear that you have used imazing for a local backup, which is a wise choice. When you can't use iCloud to back up your iPhone, using other methods is the right choice.

Hey, I saw an article repairing the iPhone that can't be backed up to iCloud:


If so that,why not backup them to another devices (PC),that is good way,too.
