The EnumBackups method enumerates metabase backups stored in one or more backup locations, retrieving the location, version number, and date of each backup.

  bstrLocation As BSTR,
  lIndex As LONG,
  pvVersion As VARIANT,
  pvLocations As VARIANT


  • bstrLocation
    [in] String containing the location. If an empty string is specified, all backup locations will be searched.

  • lIndex

  • pvVersion
    [out] Pointer to a VARIANT containing the version number of the backup enumerated.

  Dim CompObj, Index, Version, Location, GMTDate, LocDate, MinDif  
  MinDif = Session("sTempDif")  
  On Error Resume Next

  Index = 0  
' Iterate until method returns an error.  
  Do While True  
    ' Empty location input string means enumerate all locations.  
    CompObj.EnumBackups "", Index, Version, Location, GMTDate  
    If Err.Number <> 0 Then  
      ' If error returned, no more backups to enumerate.  
      Exit Do  
    End If  
    Response.Write Version & ", "  
    Response.Write Location & ", "  
    Response.Write GMTDate & ", " 
    ' Convert to server local date and time.  
    LocDate = DateAdd("n", (-MinDif), GMTDate)  
    Response.Write "(" & LocDate & ")"
