Apple has introduced end-to-end encryption for iCloud backups, providing an additional layer of security for user data. This feature is part of Apple's Advanced Data Protection for iCloud, which offers the highest level of cloud data security. With end-to-end encryption, only the user's trusted devices can access and decrypt their data, and not even Apple can access it. This feature is available for various data categories, including iCloud Backup, Photos, Notes, and more.
