Before you excitedly proceed to install iOS 12 on your iPhone or iPad, keep in mind that it is still a public beta. This means that it will inevitably lead to bugs and issues. Therefore, before you install the iOS 12 public beta on your iPhone or iPad, make sure to create its backup. In case you’d want to go back to iOS 11, you can simply restore this backup.

Part 1: How to Backup iPhone Data before Installing iOS 12

There are two different ways provided for you to backup data with a computer. iTunes and iPhone Data Exporter are two great helpers, allowing you to back up and restore data within a few clicks.

Method 1: Create an Backup in iTunes

Step 1. Connect your iPhone to your Mac or PC and launch iTunes.

Step 2. Click on the iPhone icon from the iTunes top menu bar.

Step 3. Tap on “Back Up Now” button. If you want extra security, click on Encrypt Backup. iTunes will begin to create a backup of your iPhone on Mac or computer.

Note: After the process is done, you can check to see if the backup finished successfully by clicking iTunes Preferences > Devices (on a Mac) or Edit > Preferences > Devices (on a PC).

Method 2: Create an Backup via iPhone Data Exporter

iPhone Data Exporter can selectively transfer data from iPhone to a computer for extra security, such as contacts, messages, photos, videos, calendars, notes, WhatsApp chats and more. You can also view and extract data in iTunes or iCloud backups without restoring the backup to an iOS device.

Step 1. Install and run the program. Then connect iPhone to PC.

Step 2. Select a Backup Mode.

Step 3. Choose data and backup to your computer with a simple click.
