How does iPhone6s back up data to a computer?

Open iTunes, connect iPhone6s to iTunes, and the iPhone icon will appear in the upper left corner. (If iTunes is not installed, go to Apple official website to download iTunes installation.)

Click the icon to enter the summary interface of iPhone. At the bottom left is automatic backup, that is, after clicking synchronization, it will be automatically backed up.

At the same time, you can choose encrypted backup, which will back up the password and health data on the iPhone, otherwise it will not be backed up.

You can see manual backup and recovery in the lower right corner. Click Back Up Now.

Then the backup progress bar will appear at the top.

When the progress bar is completed, the backup is completed.
