我用于按钮的代码

protected void btn_backup_Click(object sender, EventArgs e)
    {
        try
        {
            Class_Backup objbackup = new Class_Backup();
            objbackup.BackUpPath = "SalvageManager" + DateTime.Now.ToString().Replace("/", "_").Replace(":", "_").Replace("-","_").Replace(" ","_");
            objbackup.BackupData();
            if (objbackup.OperationStatus != false)
            {

            Response.ContentType = "application/bak";
            Response.AppendHeader("Content-Disposition", "attachment; filename=" + objbackup.BackUpPath);
            Response.TransmitFile(Server.MapPath("~/DataBaseBackUp/" + objbackup.BackUpPath));
            Response.End();
            //Response.Redirect(Server.MapPath("~/DataBaseBackUp/" + objbackup.BackUpPath),false);
        }
        else
        {
            lbl_message.Text = objbackup.ErrorMessage;
        }

    }
    catch(Exception ex)
    {
        lbl_message.Text = ex.Message;
    }
}

当我单击按钮时发生以下错误

错误：无法打开备份设备“D:\INETPUB\VHOSTS\salvagemanagers.com\httpdocs\DataBaseBackUp\SalvageManager8_19_2013_12_18_01_PM”。操作系统错误3（系统找不到指定的路径。）。BACKUP DATABASE 异常终止。

确保该路径存在于您的数据库服务器中，而不是您的客户端计算机上。
