Use this section to back up your device in iTunes, then store or copy the backup for backup. If you have returned to the current version of iOS after updating your iOS beta, only one backup is stored or copied.

1. Make sure you are using the latest version of iTunes.
2. Connect your device to the computer and open iTunes.
3. If you want to store Health and Activity data from your iOS device or Apple Watch, you need to encrypt the backup: Select the backup box with the Encrypt name [device] and create an easy-to-remember password.

Note: Type your password and save it somewhere safe, because there is no way to restore iTunes backup without this password.

If you don't need to save Health and Activity data, you can create backups without encryption. Just click Back Up Now .

Wait until the backup process finishes. Then go to iTunes> Preferences> Devices on your computer.

Store or copy your backup: If you use Mac, click on the backup you just created, then select Archive. If you use Windows, find a backup, copy and save the copy to another folder. If you decide to return to the current version of iOS, you will need to have the backup stored and copied.

Now you can install the iOS beta version. Remember to update this iOS beta version. To learn more, use the sections below.
