Final answer:
The backup for an Apple iPad is typically performed through iCloud Backup, which requires a Wi-Fi connection and can be enabled in the device's settings, although iTunes Backup is also an option when using a computer.
Step-by-step explanation:
The backup for the Apple iPad is primarily done through a feature known as iCloud Backup. This feature automatically backs up your iPad whenever it is connected to a power source, locked, and connected to Wi-Fi. To enable iCloud Backup, you'll navigate to the Settings app, tap on your Apple ID at the top, then select iCloud, and finally iCloud Backup to switch it on. It's important to ensure that you are connected to Wi-Fi during this process and that you have enough iCloud storage to complete the backup. Apple provides 5GB of free iCloud storage, but if you need GB, you can pay for additional storage.
Another method of backing up an iPad is using iTunes Backup. For this method, you will need to use a computer with iTunes installed. Connect the iPad to the computer with a USB cable, open iTunes, click on the iPad's icon, then select 'Back Up Now' under the 'Backups' section. iTunes Backup is a suitable alternative if you do not have enough iCloud storage or prefer to have a local copy of your iPad's data. Please note that starting with macOS Catalina, iTunes no longer exists as a standalone application, and the backup feature is found within the Finder app on Mac.
