Several users have reported that when they attempt to create an iPad, iPhone, or iPod touch backup, they get the following error message: iTunes could not back up the iPad/iPhone/iPod because an error occurred.
Fix:
Try each step until you resolve your issue:
- Restart your computer.
- Make sure you have the latest version of iTunes (or Choose iTunes > Check for Updates)
- Ensure that your computer’s OS is up to date.
If your issue was not solved, it may be that you have a corruption in your current back up files: To resolve this: First; Back up your backup: iTunes stores the backup files in the following locations:
Mac: /Library/Application Support/MobileSync/Backup/
Windows XP: \Documents and Settings\(username)\Application Data\Apple Computer\MobileSync\Backup\
Windows Vista and Windows 7: \Users\(username)\AppData\Roaming\Apple Computer\MobileSync\Backup\
Locate your back up files and get a copy of your backup; then go to iTunes > Preferences > Devices > Device backups. This is where you can delete older backups. Delete the current back up and try again to see if the issue is fixed.
