Q: iTunes could not backup iPhone because the iPhone disconnected

I've tried seaching for an answer for this problem and can't find one that works. I've tried the basics and even restored my iPhone 4S (and restarted it). Yet, I still keep getting the above message every time I try to back up even though my iPhone is hardwired to my laptop. Any other ideas out there to solve this one?

 

Thanks!

    I don't know how much more help I can be. Is the phone showing that it is charging when it is connected? Have you tried disconnecting all other USB devices when syncing?

     

    You already tried changing the name of the backup folder as I recall. Can you try a different computer? To do this first go to iTunes Preferences, Devices tab, and check the box to prevent syncing automatically. Then connect the phone, right click on it in the left column and choose "Back up" (iTunes 10), or click the iPhone button, then Backup (iTunes 11). This will only create a backup, not a sync.

     

    Also, have you tried backing up to iCloud? (You might have answered this, but I don't recall).

    Hi Lawrence,

    Yes, it show as charging. I only connect iPhone to MacBook during syncing, no other device.

     

    Ya, I changed back up folder name.

     

    I had my back up, then I update my iPhone iOS to 6.1. Then now I could not restore my back up to my iPhone.

     

    Thank you.

    That's the one to rename or delete. I see 2 backups in the folder; do ou have more than one device syncing to iTunes? If so, you will need to back them both up again after deleting or renaming.

    I had this same problem but now it's fix.

    For me it was because i was using a cheap USB cord.

    Once i switch back to my OEM apple USB it "backup" just fine.

    Hope this help some of you guys having this problem...

    My case is iPad 4. 

     

    Deleted the Backup files in Library > Application Support > MobileSync as told above. 

     

    iPad = iPad 4 iOS 6.1

    iTunes = 11.0.1

    Mac OS = 10.8.2

    Original Apple lightening cable connects to USB port (has changed USB port but failed.)

    Using iPhone 5 with the same iMac (same cable) and no problems in iPhone.

     

    Try to do iCloud Backup, but not enough storage on the cloud.  Check and read along the net to find a solution but none works in my case.

     

    Please help

    I've tried renaming the folder, but it still doesnt work. plus, the folder in iTunes/mobile backups is empty. But if I access it thru iTunes, the backup is there - any suggestions? 

    There isn't any antivirus and I've tried deleting the newer backups and it still isn't working.

     

    I've just updated iOS 6 into a 3GS phone, the previous software was ios 3.3. The apps were transferred over in the process but the contacts and photos are in the backup which i need. PLEASE ADVISE

    I am also having this problem on my 4th Generation iPod Touch.  It only began happening after I updated iOS from 6.0.0 to 6.0.1.

     

    When I sync, I get the message "iTunes could not backup the iPod because the iPod disconnected".  The remainder of the Sync takes place fine. 

     

    I went into the Library folder and deleted the backup that was there.  Now after a failed backup there is a smaller folder in its place.

     

    I have tried a brand new USB cable, and I have tried every USB port directly on my Mac.

     

    I have a PPC G5 Mac running Mac OS 10.5.8.  iTunes 10.6.3.  iPod 4th Generation iOS 6.0.1.

     

    This problem is driving me crazy.  I remember having a similar problem years ago with my iPod Touch 2nd Gen, but I can't remember how I resolved it.

     

    I have held off updated iOS to 6.1, but tried the other day and the update would not proceed because the backup failed.

     

    Should I just bite the bullet and restore my iPod?

     

    Thanks

    I think I may have found a solution.

     

    I removed the current backup folder from ~/Library/Application Support/MobileSync/ as described above.  I then restarted iTunes.

     

    In iTunes I selected my iPod (connected) from the menu, and then enabled "Encrypt local backup".  This prompted me for a password for the encryption, and then immediately began backing up the iPod.  The backup went to completion!   Of course, I am not really sure if this back up is not corrupt, but a few minutes later I told iTunes to back up the iPod, and it backed up without an error message.

     

    I will post if the problem begins happening again.

    Greetings all, I seem to be in the same boat. Because of my own negligence, somehow I've let this issue slip since september, my last successful update.

     

    Nothing seems to be fixing it for me, but on top of this issue I also have a huge "other" section of my iphone storage, 13gb. And I'm having issues with the phone always having full storage.

     

    Any thoughts?
