I am having problems backing up my iPhone 4s. Every time I try a message comes up saying "iTunes could not back up the iPhone because an error occurred" I have tried backing up to my Mac and via iCloud and neither will work. iTunes has been updated to 10.7. I have deleted old backups from iTunes. It is preventing me from installing iOS 6 on it. My iPad 2 backs up and installed iOS 6 with no problems at all. Any help would be appreciated!!

    You might try checking ~/Library/Application Support/MobileSync/Backup to see if there is a backup there that doesn't appear on the iTunes backup list.  If there is, manually delete it and try backing up again.

    You may need to reset the lockdown folder, or take one of the another troubleshooting steps mentioned in this article: http://support.apple.com/kb/TS2529.

    Unfortunatly nothing seemed to work so I went for the drastic option and a full reset! I managed to restore from my iPad 2 backup so lost very little. Thanks for the help though!

    You're welcome.  Glad it's working again.

    I had the same error and just fixed it.

     

    I'd moved the backup files to an external drive then deleted them from the library, but even without old backups, the process failed.

     

    I tried many of the above suggestions, but eventually I tried unchecking the "Encrypt iPhone Backup"

     

    My previous backups were encrypted with a password, so when I unchecked the box, I was prompted for that password, which let me remove the encryption.

     

    I then rechecked the box, entered in a "new" password, but I used the same one as before. The back up ran and showed progress in a pop-up window. A few minutes later, it was done.

     

    I've since tested it through the normal process and everything is working again.

     

    Hope this helps.
