    Shell script backup problem.


    When i try to create a backup i am getting an error that says "tar: cowardly refusing to create an empty archive". If anyone can help i would be very appreciative.

    Code:
    #!/bin/bash
    
    clear #clears all other commands
      
       echo "-----------------------------------------"
       echo " **************Main Menu*****************"
       echo "-----------------------------------------"
       echo "Choose an option"
       echo "[A]Backup"
       echo "[B]Restore"
       echo "[C]Quit"
       echo
       echo "-----------------------------------------"
       echo
       read option
       case "$option" in
    
       "A" | "a" )  
       read -p "name your backup : " tarball
       read -p "Directory to back up: " bckdir
       echo
       tar -cf $tarball $backdir
       ;;
    
       "B" | "b" )
       read -p "Name of restore file: " tarball
       tar -xf $tarball
       ;;  
       
        "C" | "c" )
        
        echo "Exiting......"
        exit;;
      
    
    
    *) echo "Please press a letter between A to C" ;;

    Looks like a typo in a variable name. bckdir or backdir?
