The error message says "The last backup could not be completed" I have been getting this message for 7 weeks
I have deleted my last backup and tried again.
My icloud storage is 9.4GB available of 15.0 GB on icloud.
I have tried to manually force a backup

iPhone 4S, iOS 7
If you get the error "Backup not successful" and you've tried deleting the last backup and trying to back up manually without luck, try the following test: Go to...
Settings>iCloud>Storage & Backup>manage Storage, tap your device name in the Backups section, then look under Backup options. Turn off all apps from backup and then do a manual backup. If that doesn't work, then this post will not help. If the backup works, then go back to the app list and turn some on and try another backup. If successful, keep repeating these steps. If it fails at some point, then try to zero in on the one app that seems to make the backup fail. (I had this problem and found one app failing, probably due to a corrupt data file.)
This process will take time, but if a backup works with no app data being used but clearly fails with the original settings, then somewhere in the mix of apps is a "bad" one.
Thanks. I did this earlier. I saw where this was posted for someone else. I still get the error message with all the apps turned off: "The last backup could not be completed" .
ipads are backing up with no problem but my phone just wont!
Same here, although when I turn off a load of apps it's seems to work, when I alternate switching them back on it stops again, surely several apps could not have corrupted since ios7?
My Iphone 4s wont backup to icloud
