Whenever you restore your device, Apple highly recommends that you perform a sync prior to restoring to back up any changes since your last sync. If you have movie rentals on the device, see iTunes Store movie rental usage rights in the United States before restoring.

Use the following steps to restore your device:

• Make sure you have the latest version of iTunes installed and running before attempting to update.

• When prompted to back up your settings before restoring, select the Back Up option (as seen in the image below). If you have just backed up the device, it is not necessary to create another.
