iTunes cannot backup because backup is corrupt

Kcutts; was the location you found this file in the same location as the previous poster?

I couldn't find it on my pc either, just type \AppData\Roaming\Apple Computer\MobileSync into the address bar once you are into your c drive and have gone past the user part. That's what I did and I found it.

So far i have followed all the above listed steps. I have uninstalled and deleted everything then reinstalled. Deleted all traces of anything Apple from my PC and reinstalled and nothing. I am still unable to sync or back up my phone. Does anyone else have any suggestions? It would be nice if someone from Apple would chime in and tell us how to fix their crappy software.

It worked! Thanks much!!

thank you so much. i was having this problem on my ipad2.

I had this problem along with the "can not conect to itunes store" with all my devices. I am running windows 7, 64, itunes 10.4 (latest as of 9-21-11). After many ties from forum advice I found the problem to be with my internet security software, Bsecure. this is what they sent me and it fixed all my problems. Everything is working again. I was nervous about losing all my itunes music and such but didn't lose anything. Se below:

We have discovered that a number of parental control andantivirus products are having issues with the newest release of Itunes.Customers across all of these products have experienced the same symptoms thatyou have. We were even able to duplicate this issue on our own computers hereat Bsecure. In this same research we discovered a fix that includes removingeverything apple related from the computer, running a utility called CCleanerto ensure its all removed, then reinstalling itunes. We confirmed that thisworked with itunes 10.4 on this test machine at our office.

Please note the following,

• You should still retain your itunes library through this process as you are not deleting them from your documents\music folder & you are not changing the version of itunes you are using.
• CCleaner is an application produced by Piriform and Not by Bsecure. While we are going to assist you in installing and utilizing the product, please do so at your own risk.

Please use the steps below to complete this process,

1. Click Start
2. Open Control Panel
3. Open Programs & Features
4. Uninstall all applications related to apple in the order listedbelow,

• Itunes
• QuickTime
• AppleSoftware Update
• Applemobile Device Support
• Bonjour
• Appleapplication Support

Once these applications are all removed, reboot your system.

Now you will need to install CCleaner,

1. Visit - http://www.piriform.com/ccleaner/download/standard
2. Download and run the ccsetup310.exe
3. Select English and click OK
4. Click Next on the wizard
5. Then Click I agree on the terms and conditions.
6. Set install options how you would like (its ok to just hitinstall here if you have no preference)
7. Click finish to launch Ccleaner and end the install
8. Click yes on the popup that asks about intelligent cookies
9. Click analyze at the bottom.
10. Review the items listed and click 'run cleaner' (ensure you arenot deleting anything important to you)
11. You will be prompted to delete files, click OK after you havereviewed the items in the list.
12. Now click registry on the left
13. Click scan for issues in the bottom right
14. Click Fix Selected Issues
15. Click Yes to backup changes to the registry
16. Allow it to save your registry backup to the documents folder(this is by default)
17. Click "fix all selected issues"
18. Close out of Ccleaner and reboot your computer.

Now re-install itunes with this link,

Hope this helps other frustrated apple customers.

Has this helped anyone else yet

Hi 🙂 Is there any way I can fix this so I can restore the original back up? I dont want to lose all my data.... I trusted that my photos won't be deleted. Please help.. It keeps giving me the same message. Is there any way I can detect the corrupted file and have that specific one erased so the restore can pursue? please..

When I followed these steps I did not lose any data that I know of. I made a backup of the entire itunes media folder before hand because I haven't bought all of my music from itunes so I knew I wouldn't be able to replace it if lost.

I also have an app called Onsong that I use for music chord charts that I created a backup for but again I did not lose any data for that app. My problems just kept getting worse and more things ended up not working properly so finally I just had to do something. Don't regret doing it at all. Being a CAD person, software that doesn't work properly REALLY bugs me, just ask my wife.

If I delete the original backup, will it restore with all of my data still there?

I have Windows7 and I cannot find this \AppData\Roaming\Apple Computer\MobileSync in my C Drive under Users.. It is just me?

More than likely you haven't followed all the directions. It's probably a case of PEBKAC and not Apple's "crappy software." Not our fault you're an idiot.

Tried this solution but failed...Not sure what next?...wondering if the 1,523 photos and the 53 videos on the iPhone have anything to do with this corrupt backup?...Thanks for any ideas.

well... this really help me, thanks!

Thanks!! I agree that it's ridiculous to give the instruction and not specify how to do it. I suspect it occured when I used an old ipod cable by mistake rather than my iphone cable. The sync took alot longer but did not indicate corruption until my following sync 1 week later. Thanks to google search and this thread-problem solved!
