          d:[path][filename[.ext]] specifies the file or files to be backed

          /S to back up subdirectory files in addition to the files in the    
          specified or current directory.                                     
                                                                              
          /M to back up files that have been modified since the last backup.  
                                                                              
          /A to add the files to be backed up to the files already present on 
          the target drive.                                                   
                                                                              
          /D to back up files that have been modified on or after the date    
          specified.                                                          
                                                                              
                                                                              
 Example: BACKUP C:\*.* A:/S  <Enter>  would backup the fixed disk files and  
          all subdirectories to the A: drive.                                 
                                                                              
          BACKUP C:\MESSAGES\*.ABC A: <Enter> would backup files on the       
          fixed disk with an .ABC extension in the \MESSAGES subdirectory.
