Automatic backup on Opening database - ms-access

Question

Can anyone give me the code to create a backup/copy of the Database when opening? it I know how to use autoexec macro i just need the code. The database name is Datenbank and the back to have the time of back in its name

Answer 1

That command could be:
FileCopy CurrentDb.Name, Replace(CurrentDb.Name, ".accdb", Format(Now(), " yyyymmdd hhnnss") & ".accdb")
but you can't do that for the database file itself from inside the application.
Your best option would be to create a shortcut that runs a script that copies the file first, then opens it.
Addendum
I located a function that will create a zipped backup of the current project:
Option Compare Database
Option Explicit
' API call for sleep function.
Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Public Function ZipCurrentProject() As Long
Dim ShellApplication As Object
Dim CurrentProjectFile As String
Dim ZipPath As String
Dim ZipName As String
Dim ZipFile As String
Dim FileNumber As Integer
' File and folder names.
CurrentProjectFile = CurrentProject.Path & "\" & CurrentProject.Name
' The path must exist.
ZipPath = CurrentProject.Path & "\#dbase_bk" & Format(Now, " yyyy-mm-dd hh.nn.ss") & "\"
ZipName = "CCOLearningHub.zip"
ZipFile = ZipPath & ZipName
' Create sub folder if missing.
If Dir(ZipPath, vbDirectory) = "" Then
MkDir ZipPath
End If
' Create empty zip folder.
FileNumber = FreeFile
Open ZipFile For Output As #FileNumber
Print #FileNumber, Chr(80) & Chr(75) & Chr(5) & Chr(6) & String(18, vbNullChar)
Close #FileNumber
Set ShellApplication = CreateObject("Shell.Application")
' Copy the project file into the zip file.
With ShellApplication
Debug.Print Timer, "zipping started ..."
.Namespace(CVar(ZipFile)).CopyHere CVar(CurrentProjectFile)
' Ignore error while looking up the zipped file before is has been added.
On Error Resume Next
' Wait for the file to created.
Do Until .Namespace(CVar(ZipFile)).Items.Count = 1
' Wait a little ...
'DoEvents
Sleep 100
Debug.Print " .";
Loop
Debug.Print
' Resume normal error handling.
On Error GoTo 0
Debug.Print Timer, "zipping finished."
End With
Set ShellApplication = Nothing
ZipCurrentProject = Err.Number
End Function
