Earlier when I plugged my iPhone into my laptop via USB to charge it I got a pop up error message stating that the sync process with iTunes could not take place because the iPhone backup was corrupted. I believe yesterday in the middle of syncing with iTunes I had to unplug my iPhone and it must have corrupted the backup that was in process. Fixing this problem is easily accomplished by deleting the backup file that iTunes stores. Below I have more details about the error itself as well as steps on how to resolve the issue.

iTunes Backup Corrupt Error When Syncing iPhone:

iTunes Could Not Backup The iPhone

iPhone Sync Error Text: iTunes could not back up the iPhone “alex iPhone” because the backup was corrupt or not compatible with the iPhone. Delete the backup for this iPhone and then try again.

Resolve Corrupt iPhone Backup Error When Syncing iPhone:

  1. Launch iTunes: If you have not already done so launch iTunes. Once iTunes has finished loading proceed to the next step.
  2. iTunes Preferences: Click on Edit in the top navigation bar of iTunes and select preferences from the drop down menu as shown below.

    iTunes Edit Navigation Menu

    Once you click on Preferences the iTunes Preferences configuration window will open as shown in the below example image.

    iTunes Preferences Configuration Window

  3. iTunes Devices: Once the Preferences configuration window is open click on the Devices tab as shown in the below example image.

    iTunes Devices Preferences

  4. Delete iPhone Backup: Once the Devices preferences window is open click on the iPhone backup in question as shown in the below example image.

    Highlight iPhone Backup In iTunes

    Once the iPhone backup is highlighted click the Delete Backup button which will pop up the below verification window.

    iTunes: Are You Sure You Want To Delete The Backup?

    Click the Delete Backup button to finish the delete process. Once the backup has been deleted the iPhone backups will be empty in iTunes as shown in the below example image.

    iTunes: iPhone Backup Deleted

  5. Sync iPhone: After you have deleted the backup click the OK button to close the iTunes Preferences configuration window. Once closed synchronize your iPhone.

Your iPhone should now sync without issue.

    Finally!! After reading so many blogs, I was finally able to figure out how to fix the problem.

    I am using a MAC with latest iTunes. Had to delete all the backup files in my iTunes, which included backups from other iPhones in our family. This was the only way I could get this iPhone 3G to backup successfully and do the latest update. Tried all the other methods, including Time Zones, etc and none of them worked. I think those methods only worked on Windoze Computers :-)

    i found that deleting the past backups throught itunes and changing my time zone didnt help me….so what i did was went here (Navigate to the C:\Users\USERNAME\AppData\Roaming\Apple Computer\MobileSync) and then go into the folder “Backup” and delete the all backups in there (doesnt say “tom’s ipjone” but says things like “c0205jfurksk”)…..when i tried to delete the back ups off itunes it must’nt of deleted all of them (although it said it did) this soloution worked for me

    I’ve tried that, plus everything else that everyone has responded with and still, I get the same message!! I cannot find the backup file from the C:\ drive and so I wasn’t able to do that. :(

    Are there any other methods that you think would work? I can’t do the update without backing up my iPhone and it’s FRUSTRATING.

    Hi,
    I’m having a bit of a problem, the last back up I had done succesfully was yesterday at 19:35, then i upgraded my iphone to 4.1, upgraded iTunes to 10.1 and then tried to restore from back and am now getting:
    “iTunes could not back up the iphone “My Phone” because a session could not be started with the iphone”. I’ve tried to delete the back up files through iTunes as well as through the directory in my C:\users folder and just try a normal back but it comes up with the same message. I’ve even tried to back up on another computer but am getting the same message.
    Any ideas?
    Am using Windows 7 if that’s of any help.

    No. It is deleting a backup of the iPhone only. Regardless you might want to move the backups to a different location in case something else goes wrong before you are able to create another backup.

    [Reply]

    alex Reply:

    Hello oquinn,

    I have seen this happen before. When it does close iTunes and delete the backups directly. I would sugggest making a copy of the backups just in case you need them and after you make the backup delete the files/directories from the below directory.

    C:\Users\USERNAME HERE\AppData\Roaming\Apple Computer\MobileSync\Backup

    Hope that helps.

    Thanks.

    [Reply]

    alex Reply:

    Hello Sherri,

    Backups should happen automatically sometimes when you attach your iPhone via USB to your computer. If not then attach your iPhone via USB and right click your iPhone when it displays in the left navigation within iTunes. You will be able to select Back Up from the drop down which will backup your iPhone to your computer.

    Thanks.

  17. Mauro says:

    Hi.
    Great tip. I have the same problem myself, but I can’t go through with your suggestion until I make sure of the following: won’t deleting the backup delete all apps and stuff in the iPhone? Like, won’t iTunes not recognize it and try to format it or think it’s empty because there is no backup and sync it to nothing, thus deleting everything?
    This might be obvious because nobody commented on it, but I still gotta ask. Thank you a lot!
    Mauro

    [Reply]

    alex Reply:

    Hello Mauro,

    Deleting the backup will not delete all of the apps. Just make sure after you delete the backup that you right click the iPhone when it is attached, then first transfer purchases, and then backup the iPhone again. After that you should be all set.

    Thanks for leaving feedback as well.

    Thanks.

    go into the backup location c: users/(username)/appdata/roaming/apple computer/mobilesync/backup/ and deleting the folder thats inside.

    at first i couldnt find this path but if you go in folder options under the view tab you can check the bubble “show hidden files, folders, and drives” it will show up.

    after that sync and backup worked like normal. good luck.

    iPhone 4.2 not jailbroken, and latest iTunes iPhone4. (Again my iPad backs up just fine). I’m convinced it has to do that I had Mobile Me set up and my account terminated in january. Ever since then I get the Error Code 30, and in the LOG it says something about Domain Error. They sync still works, it’s just that no back up is written out :(

    [Reply]

    alex Reply:

    Hello Dan,

    I personally have never used MobileMe but I would try removing the application if you have not done that yet. If that doesn’t work connect your iPhone to your computer via USB and see if there are any settings within iTunes once your iPhone is connected. I believe they are located underneath the INFO tab once you have your iPhone highlighted in iTunes.

    Hope that helps.

    I am having a simular problem but is frozen with no error message. I just locks up with the rotating (wheel looking circle) coming on every 2-3 seconds. Once this circle apears it locks everything up and goes back to the locked menu. It functions long enough for you to slide the unlock bar and click on any app or not click on any app before it locks and goes back into the 2-3 second cycle of the wheel (appearing). I”ve done a soft reboot and a hard reboot. Both times when I restore the last synced file it goes back into the cycle. If when it asks to “set up new phone” I select “set up as a new phone” my phone works perfectly fine but I’ve lost all my information (Calendar and Contacts being the most important:-(. I even went as far as purchasing ANOTHER Iphone but the same thing to the new phone when I restore. Apparently there is a corrupt file that I”ve save…..funny things is that my Iphone has been synced to different home PC’s and one was over a month ago……..when I restore the month old information it goes back into the cycle:-( Is there any way for me to get the Contact and Calendar info off my locked phone…please help.

    Hi Alex,

    This seemed to elevated the issue, but how do I restore my contacts, calendar, and notes that were previously on my Iphone?

    Thanks

    [Reply]

    alex Reply:

    Hello Janice,

    It sounds as if your issue was different than was is described in the article. The notes, contacts, calendar, etc. should have still been located on the iPhone itself as you deleted only the backup from your PC. I would look to see if you have any older backups on the PC that can be restored and verify your sync settings before you sync again to make sure they are not overwriting the data on the iPhone.

    Thanks.

  61. SimonSolar says:

    Hi Alex – this is a great help
    Has anyone asked Apple why the backup becomes corrupt – not much good as a backup is it?
    Also
    Can you tell me if the sync and backup is the same thing? In the old Activesync days, deleting something off the phone meant it would ‘sync’ and delete the files off the PC !

    [Reply]

    alex Reply:

    Hello SimonSolar,

    I believe the backup can become corrupt for many reasons one of which I have seen before which is stopping a sync in the middle of the backup process can provide a corrupt backup.

    Sync and Backup should be different. The backup actually creates a folder that has incremental backups of the phone itself including settings, etc. The sync does what it sounds like and synchronizes the different categories (photos, ringtones, music, movies, tv shows, etc.) between the iPhone and iTunes.

    Hope that helps.

    Thanks.

    [Reply]

    alex Reply:

    Hello Michael,

    Sounds like some form of permission problem or that an application already has the file open. It is hard to say exactly without knowing the error message you receive when attempting to delete but I would suggest rebooting your computer after you make sure that iTunes will not start automatically on reboot. Once you reboot then attempt to delete the file and if that doesn’t work try booting into safe mode to delete the file.

    Thanks.

    Hermod Reply:

    Hi
    I had the same problem, with the missing backup from the preferences menu.

    I fixed it by opening the backup folder (:\Users\\AppData\Roaming\Apple Computer\MobileSync\Backup). The backup folder contained one folder, which I deleted. Then I went back to iTunes, right clicked my iPhone and chose Back Up. now everything works fine!

    I’m using Windows 7, so the path to the backup folder may be different in your case.

    Hello Help PLeASe,

    Please see the comment above by Hermod. The folder path to iPhone backups on Windows Vista will be the exact same as the folder path on Windows 7. If you follow Hermod’s suggestion you should be able to locate the iPhone backup not displaying within iTunes and manually remove it to resolve the issue with your iPhone backups.

    Hi, I was wondering if deleting the backup will cause the iphone to lose contacts, etc?

    [Reply]

    alex Reply:

    Hello Ersin,

    You should first make a backup of the backup just by say copying it and pasting it in another directory or something. Regardless though the contacts should not be deleted as long as they are currently displaying on the iPhone and on your PC for instance. The backup is just that… a backup so you should be OK either way.

    Just make sure to backup the backup before deleting!

    So I followed yor next piece of advice in terms off application data -apple computer – itunes however all I have in this folder is a file called itunes prefs.xml. So I cannot even delete the back up from there. Do you have any ideas what I can do?

    Thanks in advance for taking the time to answer the questions.

    alex Reply:

    Hello James,

    I have not run into your exact scenario so unfortunately I am not sure. If iTunes is complaining of a backup then it does exist somewhere. You might try reading back through all of the older comments to see if someone else mentions the same scenario. Once you find the solution let us know what it is and then if others end up here with the same problem they won’t have to go through as much of a hassle.

    Hi Alex,
    I have 3 back ups in my folder, iPhone, iPod & iPad. Do I need to delete all of these….or just the device I am trying to back up at the moment? I currently have only deleted one, the device I am trying to back up.
    Sorry for stupid questions but this is way out of my comfort zone (computers;)
    I just purchased an iPad and iMac and want to move everything over from my 7 year old HP. The Apple rep told me to set up the iPad on the HP to get it running and then back up the phone and pod before moving to the iMac. I had no real issues getting the iPad set up but now I am not able to back up the phone or pod. The iPod does not have anything I fear loosing….so I have been “experimenting” on this device with the suggestions on line,(deleting back up – updating software – restore) but I worry about losing my other two back ups (iPhone & iPad) that last worked.
    Thank you for any help you can provide!

    Hello Steph,

    What I would do is backup all the of the backup files to a different location and then delete them all. It almost sounds as if people are having the corruption problems with backups when iTunes gets confused between multiple devices such as iPhones, iPads, and iPods or something. Let us know what happens!

    Thanks.

    Hi Alex,

    It keeps giving me different errors:
    iTunes could not back up the iPod [name] because 1,2 or 3
    1. the back up was corrupt or not compatible with the iPod
    2. a session could not be started with the iPod
    3. could not be saved to computer
    Number 3 seems to pop up more than the others.

    I think I have done just about everything I feel comfortable attempting and it might be time to take it to a professional.

    I appreciate your suggestions!

    Thanks,

    [Reply]

    alex Reply:

    Hello Steph,

    #3 sounds as if either there is a permissions problem on the folder itself or you are out of disk space. Being out of disk space would also explain why you are getting corrupt backups if the backup process is failing in the middle of completion thus not providing a full backup. I would clear out any old data from the hard drive that you can. If you need to archive any of that data make sure that you back it up to a external hard drive or usb thumb drive.

    Thanks.

    Dear Alex
    I thought I had replied to you but it seems not. Sorry. I tried everything I could find and eventually sent my computer to an engineer who reinstalled Windows 7. He reinstalled itunes which worked fine until I updated itunes to a new version last night, after which itunes “hung” when I tried to backup either phone or pad. I contacted Apple who gave me detailed instructions on how to uninstall itunes [see http://support.apple.com/kb/HT1923. The trick is to uninstall each item in exactly the order instructed, otherwise it will not work. As I have 64-bit Windows 7 I then downloaded the 64-bit versiion of itunes and installed it. I could not believe it – it worked!
    Hope it will for you too.

    That should do the trick however you would have to make sure it not only uninstalls the app but also the saved data. I would suggest removing any corrupt backups that may be causing the issue but remember to back them up before deleting them from the default backup directory.

    Hello Alex J,

    Did you verify this in the iTunes interface itself or in the backup folder where it stores the backups? If via iTunes then it is likely that the backups exist but are corrupted enough where they are not displaying. The paths below are where the backups can be found on W7 and OSX Lion.

    OSX: /Users/USERNAME/Library/Application Support/MobileSync/Backup

    Windows7: C:\Users\user\AppData\Roaming\Apple Computer\MobileSync\Backup

    I have exactly the same problem and it is exasperating me. Religiously backed up iphone 4 with (windows 7 64 bit), iTunes 10.4.1.10. Today, I received an sms during backup (which usually lasted 5-10 seconds always), and i think that corrupted it. Followed suggestions, deleted the one and only backup file so none are now showing at all, and i still get the error message “COULD NOT BACK UP BECAUSE THE BACKUP WAS CORRUPT OR NOT COMPATIBLE WITH THE iPHONE”. I have reinstalled itunes. Should I maybe reinstall an earlier version of itunes, will that fix it? I am thinking whether it is worth trying to back up my iphone on the desktop computer, wiping the phone, and starting afresh on here? Or will that mess things up even further? I dont mind 2 hours of hassle, but is there any way I can backup at least my contacts and calendar? At the VERY LEAST!?

    Same exact problem. iTunes will says it cannot save file to the computer after sync. However, there is a file in the /backup folder(not itunes under preferences), but cannot delete it or move because it says running in another program. Nothing is open. And, I am just assuming this is the reason that iTunes will save the sync, but it may be something else. I have the newest version of iTunes and have restarted both the iPhone4 and the computer numerous times. I am however, able to backup on my wife’s computer but have not been able to see how that really helps me except I do have one backup there. I cannot upgrade to the 5.0 iOS on my phone unless I can resolve this problem. Thanks.

    Hello Dush,

    You can resolve this issue by simply making a backup of the backup before you delete it from the location that iTunes will look for it.

    Thanks.
