To resolve this issue, delete the backup in iTunes Preferences and then create a new backup. If you would like to retain a copy of the backup, you can move the backup file to a different location. The backup is located in the locations below.
On a Mac:
/Users/[username]/Library/Application Support/MobileSync/Backup/
On Windows XP:
\Documents and Settings\[username]\Application Data\Apple Computer\MobileSync\Backup\
On Windows Vista and Windows 7:
\Users\[username]\AppData\Roaming\Apple Computer\MobileSync\Backup\
To delete the backup file:
Open iTunes Preferences by choosing iTunes > Preferences (Mac) or Edit > Preferences (Windows).
Select Devices.
Select the device backup to delete.
Click Delete Backup. iTunes will ask if you are sure you want to delete the backup. Click Delete Backup.
Click OK.
To manually create a new backup, right-click (or Control-click) iPhone on the left side of the iTunes window under Devices and choose Back Up from the shortcut menu.
Please let me know if this resolves your issue.
