Q: iCloud Backup Broken After iOS 9 Upgrade

all previous data was deleted from mac.

also tried reset the phone.

This is annoyin, tthe thing is I didn't have this problem until 3 days ago. Why????

I have the exact same problem!  Deleted my current backups since there were some apps that were being backed up with no data and cannot start a new backup.  Won't even enable icloud backup and fails immediately

I know this is lame, but have you gone to the Apple store or phoned support - I am not sure that deleting a back up is good practice at ALL ever because it was a back up that is now gone and the Apple document I read said once you delete a back up from your device you no longer will be able to back to iCloud - have you phoned support and let them walk you through some options? Is iTunes available to you in the interim?

I understand the importance of back ups and am a wee tired of the "set up as new" as a cure when we all back up everything all the time so that never has to happen. I thought I had the same trouble and it turns out when my phone was supposed to back up it simply dropped wifi (my own issue) and could not. Once reconnected, the back up went through.

Also, you can back to iCloud via iTunes and can load on Mac or PC for free. Have you tried that and then that might get you a back up?

I have talked to Apple support several times and deleting the existing backup was what I was told to do. In my case (I've been having problems with the phone not backing up since updating to ios 9.1) deleting the backup worked because the phone did backup afterwards. However, the problem still persists for me, as I can get maybe one or two backups (automatically) then they stop completely and then I have to do a manual backup. I updated to 9.2.1 the day it came out but I'm still having problems getting the phone to work like it's supposed to.

Terrible bug. Agreed. Mine sometimes doesn't automatically back up either - to iCloud. Sometimes it does. What helps me is to wake it up long after the 24-hour mark and lock it again and wait. It then makes a back up. Left on its own, mostly mine does not. Manual back ups to iCloud are not a problem. So, I am  grateful (though annoyed, too) that it won't do it on it's own. Do be sure it's not dropping wifi - mine does (no other device does) even on my own network. So,it charades as not backing up when in fact it can't. If you're one to wake in the middle of the night peek at it and make sure it's holding it's wifi.

I Talked today to apple care, after doing several things, they passed my issue to level 2, again more tests (almost the same I did previously) and they passed my issue to the engineers, not sure what that means and how long will it take. I gave my permission to them get into my account to perform some test.

anyone in my situation?

ive had this problem  since September 19th!

I just backup to my computer, hopefully they fix this soon!!!

Same situation. But they don't ask me permissions to use my account.

ps: sorry all for my english.

i really want my iCloud to backup!!

this has been going on for to long

got an idea!

if you can talk to engineers, ask them to fully wipe your icloud drive data.

i think it can help to resolve backup conflicts, i think, is something wrong with data because my second ID creating backup succesfully.

But, be sure to make a local copy of all your data on the computer

im just going to wait till they fix It! If they dont fix it I'll prolly which.

Thats what I thought too. Before the engineers took my case, I had to reset my password and use a new one they gave me to grant the engineers access. I had to agreed a text they read, giving my permission.

does yours work Now ?

Nope, this conversation was just a few hours ago. Still waiting, I'll receive and email or a call when it's solved
