"the last backup could not be completed"

After fighting with trying to get my phone to backup I figured out why it was failing.

There are two separate areas for iCloud backup.

Make sure you delete the previous backups in both locations then do an manual backup.

iCloud location one:

Settings - iCloud - Storage and backup - Manage storage

iCloud location two:

Settings - General - Usage - Manage storage

thx, worked nicely for me

I'm having the same problem with my 4S and none of the suggestions worked for me. But I want to add something that I don't think anyone else mentioned. When I go into iCloud>storage & backup>manage storage and tap on "iPhone," it doesn't display my large list of apps with the option to turn any of them off. Under Documents and Data it lists just three of them but nothing else. But in the area where the list normally appears, one of those swirly things just spins and spins endlessly. In following one of the suggestions in this thread, I deleted my last backup on the iPhone. Would this cause the apps not to be listed? Also, my phone is jailbroken. Could this have something to do with iCloud not backing up? I'm thinking of restoring just to see if that fixes it. But I'm hoping I don't have to do that. Any help would be most appreciated. Thanks.

UPDATE: The problem on my iPhone definitely had something to do with the jailbreak. I restored my phone and now the iCloud backup works like a charm.

Hi richpharm,

I was reading you iCloud sync fix

hi!

I've solved it!

0. Plug iphone to USB

1. Turn off in iTunes "backup to iCloud" by choosing "backup to this computer"

2. Sync

3. Go to iCloud and delete all previous backups.

4. Turn on in iTunes "backup to iCloud".

5. In iPhone click backup to iCloud

after few minutes it was done!

Cheers 😉

But where and how do you delete step #3."Go to iCloud and delete all previous backups."?

Thanks!

Hi!

Just go to Settings->iCloud -> scroll to "Storage&Backup" -> manage storage -> Go to previous backups -> Delete

Cheers

If the iCloud backup issue happened to you in the setting of having a jailbroken iOS device and only started developing in February 2013, then it's possibly due to the interference caused by a cydia package PKGBackup (if you have it installed, that is).

To quote a solution from this page:

1. Uninstall PkgBackup

2. reboot phone (not respring)

3. Reinstall PKG

4. Launch PKG (you can let it analyze) then press home.

5. go to settings..try the iCloud backup and it should work. PKG will work as well.

Worked like a charm for me.

You're my man Changyang1230! That fixed it for me as well! Thx so much!

WORKS!!

EXCELLENT ! I was about to lose hope until I dug deeper into seraching for answers. Bam fixed!!

(animation) Backing Up...

Estimating time remaining... (About 6 hours remaining)
So far so good!!!

This worked for me, AND it solved the sync issue I was having where my iPhone was stuck on "Waiting for changes to be applied..." So, for anyone having either issue, set your backups to computer instead of iCloud, and then sync.

Thanks, richpharm!

Hey there....

I am struggling with deleting a back up. As it says its in use... I onyl restored my new iphone a few days ago from the back up. My storage space is full, so want to delete the old back up, but it wont let me as it says its in use... what do I do?

1. Uninstall PkgBackup

2. reboot phone (not respring)

3. Reinstall PKG

4. Launch PKG (you can let it analyze) then press home.

5. go to settings..try the iCloud backup and it should work. PKG will work as well.

Awesome dude it was PKGbackup for me too! Thanks for posting!!!!!!!!!

@Krg5272Worked for me, even though after deleting it from location 1 nothing was visible in location 2.

Therefore, just deleting the backup (which then turned iCloud back up off) did the trick for both mine and my wife's iPhone 5. Thanks.

I have an Iphone 5 and it will let me back it up on my computer when I click on backup on itunes but when i click on icloud backup it says its never been backed up and when I try it on my phone it wont load it just keeps saying backing up and a wheel keeps turning and says estimating time remaining but never says a time. And then after awhile it says it cannot backup. What do I do now?
