EP Plus: How do I have 2 excelpackage.saveas?

Hi members,

I am using EP Plus for my export to excel function, for my export function, I will need to have 2 saveas, 1st saveas which is a save dialogue to allow user open/save/saveas and my 2nd saveas to allow the excel file to be saved directly into the specified folder in the server as a backup copy.

Thus my issue here is that my 2nd saveas does not work (no error popup during debug, no files generated either for 2nd saveas).Please advice. thanks!

 ExcelPackage package = new ExcelPackage();

            var filename = @"REPORT_" + datetime.ToString("dd-MM-yyyy_hh-mm-ss") + ".xlsx";

The below codes works (my 1st saveas for user to choose to open/save/saveas):

            Response.Clear();
            package.SaveAs(Response.OutputStream);
            Response.AddHeader("content-disposition", "attachment; filename=" + filename + ";");
            Response.Charset = "";
            Response.ContentType = "application/vnd.xlsx";
            Response.End();

The below code does not work(my 2nd saveas to save file directly into server): 

            string path = @"C:\Users\testacc\Desktop\Test\" + filename +";";
            Stream stream = File.Create(path);
            package.SaveAs(stream);
            stream.Close();
            byte[] data = File.ReadAllBytes(path);
