If, heaven forbid, you have problems with your iPad or iPod you will be relieved to know your content is safe if you have backed up your devices. Fortunately this is easy to do. Plug your device into your syncing computer. Open iTunes. Find the icon of your iPad/iPod from the left column of the iTunes screen. Right click, or control-click, on the icon. You will see a drop down menu that includes the option to “Back up”. Select this and wait for the iPad/iPod to finish syncing. That’s all there is to it.
Be sure to backup your iPad/iPod anytime you add any new content.
