        if (Directory.Exists(backupPath))
            backupTextBox.Text = backupPath;

Add STAThread Attribute to the main method.

static class Program
{
    [STAThread]
    static void Main(string[] args)
    {
        ...        
    }
}

You code works correctly. result is DialogResult.OK when you click FolderBrowserDialog "OK Button". if you click "cancel" or "close" button when result value setting is DialogResult.Cancel

Here's the code, it works fine for me.

using (var dialog = new FolderBrowserDialog())
    if (dialog.ShowDialog() == DialogResult.OK)
    {
         // some code...
    }
