Can't backup to iCloud after iOS 8.1 update?

I am have exactly the same issue!

I have this issue all of a sudden also, after updating to iOS 8.1 (I confirmed that the last successful backup to iCloud was prior to installing the latest update). I even turned off photos backup to iCloud, thinking that I had perhaps just accumulated too many photos, but still no success. I have just the one iPhone 5 in my iCloud account. Sounds like something has changed that is either using a LOT more iCloud storage, or something is computing the amount of storage needed for a backup incorrectly. Meanwhile, I've backed up the phone to a Windows XP computer..

SSame issue here. Driving me nuts.

also iphone shows drive as "@iCloud.com" ipad as "@Me.com".

ALso so birthdate and email address changed slightly but won't let me amend birthdate says "password not long enough" or similar! Bizarre...I give up.

I had the same issue after ios 8.1 update. Iphone told me icloud backup was not completed because I did not have enough space which I do have enough space. So I deleted my backup from icloud. NOW my iphone does have a opinion in the icloud menu to even do a backup. Apple you have an issue here!!!

This is my big problem with Apple support: they know they have an issue (or should know) but they never let anyone know until they are good and ready to put out an update.

Apple you could avoid a lot of user frustration and anxiety if they would just knowledge these kind of issues ASPA and let us know when is will be fixed.

Instead I spend two hours fishing around for an answer that isn't available yet, with no way to even know if Apple is even aware that they have a problem that needs to be address.

Apple you need to put up a know issue page....please!!

Update to my post-I spent about an hour on chat with an Apple rep who was less than useful. I wound up backing my phone up to iTunes then I deleted my backup from icloud. I tried to do a new backup to icloud and it did actually work. This whole process just speaks to the direction Apple is going with both their products and services.

Funny I try deleting my icloud backup of my iphone 5s. Now I can't find you the icloud menu where to do a backup.

Everyone this appears to be a bug with iCloud after updating to 8.1.

Here is how I fixed the problem on my iPhone.

1. Manual backup your phone to iTunes if you are concerned.
2. Delete your old backup from iCloud
   1. Go to: Settings > iCloud > Storage > Manage Storage > (select device under "BACKUPS" that is giving you problems) > scroll to bottom and "Delete Backup"
   2. Your iCloud should report more storage now, example 20GB available of 20GB etc.
3. Force a backup to iCloud

   Settings > iCloud > Backup (needs to be turned on after deletion) > enable iCloud Backup > Back Up Now

My phone stopped reporting that storage was full after I performed these steps.

Hope it helps.

velvetmidget, thanks! That fixed the problem for me also.

I haven't been able to get a back up either. I've deleted my previous back up file and tried to force a new one, still no go. After trying all I'm able to get is "Estimating time remaining..."

Blade_27, you may just need to be a bit more patient. Probably what's going on is that some sort of incremental backup scheme (a la Time Machine) is being used, and since we deleted the backups, the first time the phone is backed up, it will have to do a full backup. Mine sat with that "Estimating time remaining.." message on the screen for 10 or 15 minutes, then took nearly another half-hour to actually finish the backup. I'm guessing that the next time a backup is done, only the changes since the first backup will have to be transferred and it will take a lot less time.

Well after all must a full month of not having any back ups done. My phone has mysteriously updated all on it's own this morning.

That is hilarious. Like when you take your car to the mechanic because it makes this noise all day everyday then it stops on the way to the mechanic.

Glad it works for you now.

I've tried Velvet's method but it appears to only work once; the next time my phone tries to backup the issue returns. It looks like iCloud is improperly calculating how much storage is needed to perform a backup. If the new backup will be the same size as the existing backup, there should be no storage problem. However, it looks like it thinks it needs enough storage to hold the both the previous backup and the new backup at once, when obviously the new backup should replace the old.

I'm having the same problem here with a 5s. Keep getting an error that says that backup cannot be completed. I have plenty of iCloud space avialable and backups had worked perfectly prior to updating to iOS 8.1. Weird and frustrating.

I had the same problem. By deleting the old backup this was resolved. The iCloud system had not backed up for over a month.

I assume this means that I will have to do this manually until Apple fixes the problem.

Looks like an easy fix for Apple but it would be nice if they acknowledged the problem and provided the simple workaround and an estimated time for update.

Apple appears to be frustrating a lot of customers unnecessarily.
