Hi imall4Him,
Thanks for visiting Apple Support Communities.
These troubleshooting steps can help if you are not able to back up your iPhone 4:
After you restart your computer and iOS device, try to back up again.
Keep only your iOS device, keyboard, and mouse plugged in. You need to plug your device directly into the computer.
To back up or restore from backup, you need to free up enough space on your hard drive to store the backup or the capacity of the device.
You may need to update, configure, disable, or uninstall your security software.
Create a new administrator account on your computer and back up using the new account.
Follow these steps for Mac OS X or these steps on the Microsoft website for Windows. If you can back up using a new administrator account, log in using the original user account and follow these steps:
- Make sure the account is an administrator.
- Check the permissions for the directories where iTunes writes the backup.
- Mac: Use Get Info to check the permissions on the MobileSync and Backup directory.
- PC: Contact support for your copy of Windows.
- See if there is an issue with the original backup:
- Rename the Backups folder.
- Open iTunes and try to back up again. Copy your backup before using iTunes Preferences > Devices to delete your backup.
If you can't back up as a new user, try to reset the Lockdown folder. If you reset the Lockdown folder, you may be able to start or save your backup.
- Unplug all iOS devices from your computer and quit iTunes.
- Reset the Lockdown folder.
- Plug in your iOS device.
- Open iTunes and try to back up.
if the drivers are out of date, Intel chipsets may cause backup or restore issues. If you have one of these chipsets, you can follow the steps to fix issues syncing iOS devices with Intel Chipsets.
If you have another computer, try to back up on it. To restore from a different computer, copy the backup into the backup folder of the new computer. (You may need to create a Backup or MobileSync folder.)
If you tried these steps and see the message again, contact Apple Support or your wireless carrier (if you're using an iPhone).
