Thanks. I don't really know what is backed up. In Vista, using backup/restore you are prompted to put a dvd in then it automatically backs up. I presumed that all files were included. I don't know what an "Image backup is" .After I had done a complete recovery, I restored the files to Vista, I remember all program files were sucessessfully returned. All I wish to know is when Windows 7 is installed, will the same dvd restore the backed up files on to Windows 7.
