How to back up Apple's SMS and phone records?

According to the following steps, you can back up the short messages, call records and photos on your mobile phone to your computer.

Connect the Apple phone to the computer, and then open the iTunes software. After the iTunes software recognizes the connected mobile phone, click the "small mobile phone icon" in the upper left corner, then select "this computer", click the "Back up now" button, and click "Do not back up the application" in the pop-up window.

The backup time may take several minutes to dozens of minutes, so please be patient. When the progress bar at the top of the window disappears, the backup is complete. At this point, you can remove the Apple phone from your computer and close the iTunes software.
