I'm starting over with a new computer after transferring everything from an old one, which caused duplication of files and folders. Causes me to wonder what protocol is used by the backups. When a file that has been changed is saved to backup does it overlay and replace a version of the file previously saved or is one with the new changes also saved? If I edit my MY PICTURES folder, deleting some pictures, when the folder is next backed up, will it contain the pictures I deleted or not? Ditto MY DOCUMENTS?
