Apple announced on Wednesday that it plans to allow users to encrypt additional kinds of iCloud data on its servers, including full backups, photos and notes.The feature, called Advanced Data Protection, will prevent Apple from seeing the contents of some of the most sensitive user data stored on its servers and will make it impossible for Apple to provide the content of an encrypted backup to law enforcement.Encrypted backups will be opt-in, according to Apple, and will be available in the U.S. before the end of the year.While Apple has previously encrypted a lot of data it stores on servers, entire device backups that included text messages, contacts and other important data were not end-to-end encrypted, and Apple previously had access to the contents of the backups.In 2018, Apple CEO Tim Cook said in an interview that one factor in Apple's decision-making around end-to-end encrypted iCloud backups is that its users expect Apple to be able to help recover their data."
