Backing up your iPhone to iCloud is crucial to ensure that your data is safe and secure. iCloud backups include all your photos, videos, contacts, messages, and more, and can be used to restore your device in case of data loss or damage. Checking your iPhone's iCloud backup is essential to ensure that your data is being backed up regularly and properly.
To check your iPhone's iCloud backup, go to Settings, tap on your name, then tap on iCloud, and tap on iCloud Backup. You will see the date and time of the last backup, as well as the size of the backup. If the last backup was recent and the size is significant, it means that your data is being backed up regularly and properly.
