Apple announces plans to encrypt iCloud backups

"The move will please security advocates, many of whom previously pointed to unencrypted iCloud backups as a weak link in Apple’s privacy policy. It also means that user data content would not be exposed if Apple’s servers were ever breached.

It could upset law enforcement, which has used Apple’s policy of not encrypting backups as a way to obtain materials in investigations even though Apple’s iMessage and devices are encrypted."
