Preciso de ajuda, estou fazendo um programa de backup só que não esta dando certo alguem poderia me ajudar
aqui esta o codigo.

 try { 
     JFileChooser jf=new JFileChooser();
     jf.showSaveDialog(null);

String arquivo = null;

arquivo = jf.getSelectedFile().toString();

File file = new File(arquivo);

                            if(file.exists()){

Object[] options = { “Sim”, “Não” };
int opcao = JOptionPane.showOptionDialog(null,“Este arquivo já existe. Quer sobreescrever este arquivo?”, “Atenção!!!”,
JOptionPane.YES_NO_OPTION, JOptionPane.QUESTION_MESSAGE, null,options, options[0]);
if (opcao == JOptionPane.YES_OPTION) {
Runtime bck = Runtime.getRuntime();
bck.exec(“C:\Program Files\Microsoft SQL Server\MSSQL12.SQLEXPRESS\MSSQL\DATA\IMOB.mdf\ -v -v -v --host=localhost --user=sa --password=imob14,03 --port=1433 --protocol=tcp --force --allow-keywords --compress --add-drop-table --default-character-set=latin1 --hex-blob --result-file=”+arquivo+" --databases compuponto");
JOptionPane.showMessageDialog(null, “Backup realizado com sucesso.”, “Tudo OK!”, 1);
}else{
JB_BackupActionPerformed(evt);
}
}else{

                    Runtime bck = Runtime.getRuntime();   
                    bck.exec("C:\\Program Files\\Microsoft SQL Server\\MSSQL12.SQLEXPRESS\\MSSQL\\DATA\\IMOB.mdf\\ -v -v -v --host=localhost --user=sa --password=imob14,03 --port=1433 --protocol=tcp --force --allow-keywords --compress  --add-drop-table --default-character-set=latin1 --hex-blob  --result-file="+arquivo+" --databases compuponto");  
                    JOptionPane.showMessageDialog(null, "Backup realizado com sucesso.", "Tudo OK!", 1);   

}

 } catch (IOException ex) {
    Logger.getLogger(JF_Mysql.class.getName()).log(Level.SEVERE, null, ex);
}
