How to back-up in the new iTunes
With the latest update to iTunes, how you get to the shared files has changed. Here’s how you find the backup files now.
First, run the back-up within the My Recipe Book app on the settings screen. Then attach your iPad to your computer.
Then, open iTunes. It will probably open to the iTunes store. In the upper right corner, click the Library button.
After that, you will see the library with your music, etc. In the upper right, it will show that you have a device connected. Touch the button, and it will show the devices you have connected. Touch the name of the iPad you want to download from.
Once you are on the page of your iPad, you will see what looks like the old iTunes screen, with the bar at the top that has Summary, Info, Apps, etc. Touch the apps button. You will see all of your apps listed. Scroll to the bottom, and you will see the File Sharing section. Tap the Recipe Book icon, and you will see the backup files there.
