Suddenly my iPhone 5S cannot backup to iCloud

Thank you for your solution. While my problem was not caused by going back to a previous iOS, your solution worked for me, too, when my backups suddenly got stuck.

My problem had been caused by too little iCloud storage. After I deleted some backups and bought more space, it got stuck. I did a backup via iTunes and then followed your steps. Now iCloud backup is back! Thanks.

Hi - i have had similar problems.

But it doesnt' mattter what I do. I have heaps of iCloud storage, I deleted my old back-ups and done several manual back ups. Following other advice in other posts I have turned off the Photo Stream back up and all other app back up in attempt to problem solve which app was causing the issue.It fails part the way through every time. When you look at the record of the failed back up, there is 3.7GB of data that has been backed up - but I don't know what.

I know Android was having issues with Facebook preventing its backup from working - but I cannot work out what this issue is!

Its driving me crazy because with IOS 8 they have suspended back up of photos to Dropbox also - so its a complete nightmare!

I also have pretty much the same problem, although a bit more complicated.

The OP's problem seems relatively simple in that it was a simple clash of the ios 7 not being able to back up to a ios 8 back up, so deleting back up solved that problem.

I'm having no such luck.

Running ios 8.0.2.

Have deleted all apps, restored device from backup with only iPhotos and iMessage history.

Still stuck on "estimating time remaining" when trying to back up.

Occasionally it would progress to back up, but then proceed to fail.

For example it would move to a point where it would say "about 16 minutes remaining", then it would say, 17, then 18, then 19, then 27 minutes etc etc. You get the idea, it would seem to backup, but then server connection would like fail and it would give increasingly longer times for ETA to backup completion, to the point where at some point it would just say backup failed.

Seems like the root of the problem may have to do with why the Wifi has been so screwed up with ios 8.0.2 on some devices.... maybe it's got to do with an Apple server problems.

I've also now restored and set up as new phone.

Still not backing up over iCloud

I think this is a common issue but with the lack of detail in the error it is impossible to work out what is causing it. I have followed Apple's advice but the instructions are very general and don't provide detail of what to do should the instructions not work.

Hey @Apple - are you going to post a response to this thread?

Having the exact same problem -

I can't back up to itunes or icloud

On Itunes i get a messafe saying there was an error trying to back up, on icloud I get an message saying The last back up could not be completed.

iphone 5, ios 8.1

After deleting/restoring and all ings possible, I tried to backup my phone in a different network, and worked just fine. It would't work ONLY in my place's network. What I did, and solved this issue once and for all, was disabling, in my router, the IPv6 type of internet connection. Can't explain why, but it did work! Hope I could help!

Happy Holidays!

"iCloud Backup Failed | There was a problem enabling iCloud Backup | Cancel | Try Again" when I toggled iCloud Backup off & on. I can access iCloud from my Mac but do not see any backups out there..where would I look? Phone is 5s & I was under the impression that I had backed it up to the iCloud on separate occasions in the past but now I'm not so sure.
It would appear that something happened in the latest update to IOS &/or OS X.

I was hoping you can help me since it sounds like our problems are somewhat similar.

I swapped out my iPhone today with the thought that i synced it to my computer/icloud. However, when I tried to restore my new phone to the last backup it says it hadn't backed up to iCloud since January. (6 months ago). I realize now it was because I was out of space. I bought more iCloud space and want to try to backup my phone to get my most recent pics, texts, etc (a ton since January). Is this possible even though the apple associate erased content on my old phone once I released it over to him?

HELP! Thanks!

I'm having the same issue, and I have the same 5S iPhone.

Went to the Genius Bar yesterday & the Apple Tech there confirmed that this is an OS9 issue. We need to wait for another update. Heck of a note, paying for extra iCloud backup & not being able to use it.

If you check iCloud Usage on your phone, you'll see that it likely has nothing or unknown listed. Even if you have the 20GB plan like I do, the phone has no idea what's there to back up.

T Thank you for suggestion, it solved problem with my iPhone 5. I had problem with backing up after installing latest update.
