Sample 1: Saves Backup with Random File Name

    Sub Backup()
      Dim lngNumber As Long
      Dim strString As String
      Dim strFile As String
      Dim strFileName As String
      Dim strPath As String

      ' Generates random number.
      lngNumber = Int(Rnd * 100000)
      ' Converts number to a string.
      strString = Str(lngNumber)
      ' Removes blank space from first of number.
      strFile = Mid(strString, 2, 5)
      ' Adds first two letters and extension to file name.
      strFileName = "Bk" & strFile & ".bak"
      ' Determines path where PowerPoint is stored.
      strPath = Application.Path
      ' Saves file with random name and .bak extension.
      ActivePresentation.SaveAs FileName:=strPath & "\" & strFileName
   End Sub
				

Sample 2: Prompts User for File Name for Backup

   Sub Backup()
      Dim strFile As String
      Dim strFileName As String
      Dim strPath As String

      ' Prompts for file name.
      strFile = InputBox("Please enter a file name." & chr(13) _
                         & "Spaces may not work correctly.")
      ' Adds extension to file name.
      strFileName = strFile & ".bak"
      ' Determines path where PowerPoint is stored.
      strPath = Application.Path
      ' Saves file with the name you input and .bak extension.
      ActivePresentation.SaveAs FileName:=strPath & "\" & strFileName
   End Sub
