How can I do an automated back-up of my attached Back-End db using FileCopy?

This function will automatically backup any attached Back-end database. It can be modified to work with multiple back-ends as well, contact me if you need help. The function below backs up to the a: drive, however you can back up to any drive that will allow writing, this includes network drives as well, just use the UNC path. It also works great to Zips and Jazz's and such.

The function as is, will overwrite the existing file every time. If you want a new backup every day, simply un-comment the appropriate lines, and comment out the one strDest value line, and it will write a file in the following format each time:

TodaysDate_FileName.mdb (i.e. 052600_MyBackEnd.mdb)

Simply copy the following sub routine into a module, replace the appropriate text, and you are ready to roll.

On the On Click event of a button simply type "Call Backup". That's It !!!

Hope it helps you.

==============================

Public Sub BackUp()
'This function backs up to the a: drive, you can back up to any location, just change the strDest Value

On Error GoTo Err_Backup
Dim db As Database
Dim strSource As String, strDest As String, strError As String
Dim strDate As String, strDateX As String

If MsgBox("Are you sure you want to back up data?", vbQuestion + vbYesNo, " Continue?") = vbYes Then
' Un-comment the following 3 lines for a new backup for every day
'strDate = Format(Date, "mm/dd/yy")
'strDateX = Left(strDate, 2) & Mid(strDate, 4, 2) & Right(strDate, 2)
'strDest = "a:\" & strDateX

Set db = CurrentDb()
DoCmd.Hourglass True

'Put any table name in here that exists in your back-end
strSource = db.TableDefs("TableNameHere").Connect
strSource = Mid(strSource, 11, Len(strSource) - 10)

' If you are using a new back-up every day, un-comment this line and replace the database name, and comment out the next line down
'strDest = strDest & "_YourBackEndDBNameHere.mdb"

' Replace with your database Back-end name and different drive letter or UNC path if desired
strDest = "a:\YourBackEndDBNameHere.mdb"

FileCopy strSource, strDest

db.Close

DoCmd.Hourglass False
MsgBox ("Backup Complete")
End If

Exit_Backup:
Exit Sub

Err_Backup:
Select Case Err.Number
Case 61
strError = "Floppy disk is full" & vbNewLine & "cannot export mdb"
MsgBox strError, vbCritical, " Disk Full"
Kill strDest
Case 70
strError = "File is open" & vbNewLine & "cannot export mdb"
MsgBox strError, vbCritical, " File Open"
Case 71
strError = "No disk in drive" & vbNewLine & "please insert disk"
MsgBox strError, vbCritical, " No Disk"
Case Else
Err.Raise Err.Number, Err.Description
End Select

DoCmd.Hourglass False
Resume Exit_Backup

End Sub
