"the last backup could not be completed"

I noticed my iPhone 3GS has stopped backing up (It is connected to a power source and has WiFi connection).


I tried to manually back up to iCloud, but I get the following message after several minutes; "the last backup could not be completed."


Today, I restored my iPhone and downloaded iOS 5.1. I still have the same issue. I deleted the old backup in iCloud and tried it again - and still the same message.


Any ideas how to solve this?

Thank you, thank you, thank you!


My iPhone 4S has never been able to sync wirelessly to iCloud, would only do it whilst in iTunes. I was continually getting messages to tell me that I hadn't backed up to iCloud in XX weeks. I tried all other suggestions such as "Delete backup" and try again, "reset network settings" and was considering deleting my iCloud account until I came across your solution.


And it just worked...again thank you.

The only way I finally fixed this after going through all the above suggestions (ie. syncing to computer, deleting backup, resyncing, restarting, etc. etc.) was to uncheck the photoroll from the list of apps to backup:

1. on ipad, go to settings>icloud>storage and backup

2. click manage storage

3. Click on the ipad (or whichever device is having issues)

4. under backup options, unchceck "camera roll"


Try manual backup and see if that works. Worked for me. I then rechcked the photo roll and the backup still works! Don't understand it, but solved the issue.


Good luck!

Oh. My. Sweet. God.


Rich, you are an absolute lifesaver. After trying every single thing under the sun, your simple "little trick" made it stop hanging at 75% of iCloud backup. (Also, backing up via USB caused an error, and I had just reformatted and was left with no backup.)


I was going to have to re-enter everything, and lose heaps of data.


I signed up to the forum just to thank you.
