Can't enable iCloud backup

I recently had an issue backing up my iPhone 6s to iCloud due to storage issues. So I cleaned up a bunch of things and even deleted the backup. Now when I go to my storage settings I'm told that I have 4.4gb available and my next backup size will be 3.2gb. But on the app list it says Photo Library is 5.5gb.(Pic attached) I don't even do an iCloud photo library and my camera roll is only 2.5gb. When I try and turn off a backup, it won't let me. I've done network resets, turned off and on iCloud backups. But I still cannot backup to iCloud. (I have backed up to my computer as a safety net)


Please help.

I'm experiencing the same issue.


After upgrading my iPad mini to iOS 9.2.1, I decided to delete my backup from the cloud as I recently uninstalled a number of apps that were causing the cloud backups to become larger. Shortly after this, I attempted to run a manual backup to iCloud but it consistently failed with the the message below.


'The last backup could not be completed.'


This continued after restarting my iPad and after I removed and re-added my iCloud account to my iPad. When I attempt to re-enable iCloud Backup after disabling it as a test, I am consistently seeing the message below.


'There was a problem enabling iCloud Backup.'


My automatic and manual backups had been working normally for a long time. I suspect that deleting the iCloud backup caused this problem rather than the recent upgrade to 9.2.1 as this seems to have been ongoing for a long time.


I also have exactly the same issue. I deleted my iPhone 5s' old iCloud backup, but when I decided to turn iCloud backup on again the iPhone prompts with an error message about enabling iCloud backup. iCloud backup though may be enabled via iTunes, but even then no manual nor automatic backup can still be done on the iPhone.


I am just gonna go ahead and subscribe to this thread with the hopes that someone someday can find a solution to my problem.

Same here (it's around a week now) and the latest update (9.2.1) didn't change a thing (iPhone 5s). It all began when I deleted the remote backup (which I've been doing from time to time without any problem).


Just to be clear (and to let you know what didn't work):


  1. I tried wiping out the iPhone and restoring from a local backup
  2. I tried logging out and in again from iCloud
  3. I even tried changing the name of the iPhone, just in case there was some corrupted hidden preference file somewhere
  4. I played with iTunes settings all the possible ways (same results: iCloud backup apparently active but it doesn't work and shows - only locally on my iPhone - zero Kb). Local backup still works fine.


Two other iOS devices are working fine and I have plenty of iCloud space available. From Apple's System Status all services are up and running.

I've been working on this issue for about a week, all started when i installed 9.3b on my iPhone, i don't think its related, but noticed 9.3b wasn't backing up to icloud even though it was enabled, first thing i tried was delete previous backups in icloud, turned off backup and after that wouldn't turn back on. Thought it was 9.3 issue, so i restored back to 9.2, backup still wouldn't turn back on. Then when on my iPad air, noticed hasn't been backup to icloud since dec 6th, manually forced backup but failed like my iPhone, turned backup off and after that wouldn't turn back on either.


I have been working with Apple support, one thing we noticed was that their test device was able to backup, however after deleting the backup from the icloud, would not backup anymore. Also noticed just on my iPhone, none of my previous icloud drive data was showing, only new items i add will sync over to my iPhone, this wasn't the case for the iPad, was working correctly.


I tried everything i can find on the net with no success. My guess is the backups are not actually getting deleted in my icloud storage, its some how still sitting there, even though apple support says they can't see any backup data on their side. Most likely my storage is corrupted, hoping apple can partition a new storage for me and migrate over. Waiting for call back from apple engineers, i will update after.

Hi, I've encountered this problem too. I've tried erase everything and backup an empty phone, the backup would not complete as well.

If I use another icloud account on the same device, the backup would be completed. And I believe it could be some settings on their server that locked up the account, messing up icloud backups.


I've tried recreating this problem by deleting the completed backups. Now my 2nd icloud account can't complete its backup after having the first backup deleted manually through the iCloud settings.

But I used to delete my old backup in order to generate a new one once a month for several years, including on iOS 9.2. It's only since a few day that it's no longer possible do activate icloud backup after having deleted the last one...So I don't think it has to do with the iOS version...

I don't know if it occurs to everybody or just to some users...

I hope Apple will rapidly solve this incredible issue...
