If you back up your iPhone, iPad, or iPod touch, you’ll have a copy of your information to use in case your device is ever replaced, lost, or damaged. Before you get started, learn the difference between iCloud and iTunes backups, then choose the method that's best for you. If you need an alternative backup, you can make one in iCloud and another in iTunes. Connect your device to a Wi-Fi network. Go to Settings > [your name], and tap iCloud. If you’re using iOS 10.2 or earlier, go to Settings, then scroll down and tap iCloud.
Tap iCloud Backup. If you're using iOS 10.2 or earlier, tap Backup. Make sure that iCloud Backup is turned on. Tap Back Up Now. Stay connected to your Wi-Fi network until the process completes. You can check the progress and confirm the backup completed. Go to Settings > [your name] > iCloud > Backup. Under Back Up Now, you'll see the date and time of your last backup.
