  1. If you're getting this error while trying to RESTORE a backup, deleting the backup isn't going to cut it. I used Decipher Backup Repair in this case, great for when you need to restore. This article is great if you need to back up!

  2. Please , help me I could not back up iphone " itunes could not backup the iphone because iphone a session could not be started " I used win 7 , computer "Lennovo G480 ".

  3. Thank u SO MUCH!
    i was getting "iTunes could not backup the iPhone because the iPhone disconnected" for my iPhone 6 and deleting the previous backup did the trick. i think it was somehow corrupted

  4. I got the same error when backing up via iTunes or iCloud. In my case, there were some applications in weird status and that caused the problem. When checking applications on Settings > General > Usages > Manage Storage, there were (null) named applications which couldn't be deleted there. So I searched those applications on AppStore, downloaded them again, and tried to delete but they couldn't be even installed properly. After deleting them on Manage Storage menu, backup has worked.

  5. This is my fix.
    My problem was caused by a dummy app, I removed it through iPhone's SETTING, GENERAL, USAGE, MANAGE USAGE.
    Look for empty app name or blank icon. Remove the app.
    Try to backup again, if fail again, check for the LOG of your iTunes.
    For Windows, go to
    a) C:UsersXXXXXXAppDataRoamingApple ComputerLogs
    b) Open the log, and see what's the problem. For my case there problem was
    [11132 @ Fri Oct 09 21:27:23 2015] [com.apple.console AppleMobileBackup.exe] ERROR: Backup message response: 101 Unable to open domain directory: No such file or directory (2) at path "/var/mobile/Containers/Shared/AppGroup/8E726549-3ED1-4171-818A-12B66843C156" (MBErrorDomain/101)
    c) For my case, this App " 8E726549-3ED1-4171-818A-12B66843C156 " caused the problem. So I just browse into my iPhone's directory using iExplorer, and create a folder with the same name. Note: My iPhone is jailbroken.
    Then I manage to backup my phone.
    Note: If you see similar error message, thats mean it's caused by an APP. Just try to delete more app and try to backup again.
    Good Luck!

    1. THanks man for putting this here. The problem is what if the iphone is not jail broken? How can " 8E726549-3ED1-4171-818A-12B66843C156 " be connected to the dummy app of interest?
