icloud not backing up after ios9 upgrade

You might try a forced shutdown to begin with, hold down the top and home buttons together until the device shuts down, then restart it.

First check that your device is correctly connected to the wifi/internet (settings > wifi)

If your back up continually fails, you might try turning off back up on your mobile device (settings > iCloud > storage & backup) and then deleting the backup file from iCloud by swiping the backup file on the mobile device (settings > iCloud > storage & backup > manage…) and then turning back up on again.

If this doesn't help, try turning off some items for back up in a pattern to try to establish if your problem is being caused by specific data on your device.

Being able to back up to the cloud can be very useful, especially if you don't have access to a computer or have infrequent access to one, however unless you specifically need to use iCloud for back up, you will find backing up to iTunes significantly more convenient and possibly more reliable.

More about iCloud v iTunes Back Up

After updating to iOS 9, all three of my iOS devices were not backing up & my previous backups were showing 0 kg & last backup was listed as never. I had backed them all up prior to updating. There seems to be some kind of glitch. I corrected the issue on my iPhone by signing out of iCloud, then rebooting my iPhone & signing back in. I then chose 'Backup Now" which worked & now the backup is showing the correct size & date.

I have the same problem. Can't back up my device in iCloud. Next copy 0 kb. Last copy - never. I have no idea what to do. iPhone 6 plus. Anyone have ideas how to fix this?

Try turning the back up option off, then on again and starting the back up again.

I tried few times, result is the same

So what exactly is it not doing.

Update is not finished, and next copy - 0 Kb.

The 0 Kb went away for me when I turned the back up off, then the next time I tried it completed.

iCloud backups seems to be messed up after iOS 9 upgrade. I've three iOS devices on two different apple IDs and they all are not able to perform the iCloud backups. Enough storage is available but the backup doesn't complete and it display the message 'The last backup could not be completed'

I tried this, to no avail. :-(

Looks like I'll have to backup my iPhone to my PC till Apple fixes this.

after the ios 9 upgrade, 'backup now' cannot be found. update appeared to run successfully to completion.

immediately after upgrade, iCloud storage showed used storage of about 0.3 gb (photos not backed up). the next morning, iCloud storage used was ZERO.

any news on a fix from apple?

I can confirm this. Hoping Apple will fix soon. Until then I'm doing manual backups through iTunes.

Since iOS 9, iCloud backup is indeed broken. It has to do with Apple's plan to implement "App thinning".

So basically, if you upgrade to iOS 9, iCloud backup WILL fail. I tested this with iPhone 6+ and iPad Mini 3, all running 9.0.1 and backup failed. I recommend using iTunes for now and NOT to restore using iCloud. God know what other bug will show up.

I'm also suffering from icloud back ups being broken, but now I also can't backup to iTunes??

I've tried resetting a few times. Logging out of iCloud and back in doesn't help either. Convenient timing. It hasn't backed up since 9/15/15 2:57 PM...

This is wholly incorrect and misleading. I acknowledge some are encountering problems (many of which get fixed), but many have had no problems at all, so typing WILL in capitals is more of a tantrum than helpful advice.
