How to back up from iTunes
iTunes can create backups of your iOS device when you:
Sync with iTunes (disabled if you have iCloud backup turned on)
Right-click (or Control-click) the iOS device in iTunes under Devices and choose Back Up
Use these steps to manually back up your iOS device using iTunes:
Connect your iOS device to a computer with the latest version of iTunes installed
Select your iOS device in iTunes under Devices
Right-click (or Control-click) the device and select Back Up
iOS device backups preserve your settings, the Camera Roll (or Saved
Pictures), and other important data. Learn more about what is stored in a backup.
