My iCloud 'Backup' of camera roll is too high as it has videos. I have deleted all the videos from camera roll on my iP4. However, when I backup to iCloud again, it is not deleting the videos from cloud. Wouldnt iCloud delete automatically (when backed up next time) the videos in cloud when it is deleted from the camera roll on iP4? Or the only option is to turn off backing up of camera roll altogether to delete the videos already in cloud backup?
