iCloud Backup is a service provided by Apple that automatically saves your important data from your iPhone, iPad, or Mac. This includes photos, videos, app data, and settings, ensuring that you don’t lose anything if your device is lost or damaged. You can easily access your backups whenever you need to restore your device or set up a new one. To use iCloud Backup, you simply need to enable it in your device settings. Once activated, your device will back up your data over Wi-Fi at regular intervals, usually when it’s plugged in and locked. This makes it a convenient way to keep your information safe without any extra effort.
