  {
  
  using (SPWeb web = site.OpenWeb())
  
  {
  
  string bPath = "C:\\Backup"; //Location where backup file is to be stored.
  
  SPExportObject exportSite = new SPExportObject();
  
  exportSite.Type = SPDeploymentObjectType.Web;
  
  exportSite.Url = web.Url;
  
  exportSite.IncludeDescendants = SPIncludeDescendants.All;
