Modules & VBA :: Backup Code Getting Permission Denied Error

I got these three code routines for backing up an Access database file from two different forums. I installed them as is, on a test database, creating command buttons for each. The test database is not password protected. I intend (if I can get one of these working) to install it on simple, single file, password protected databases.The first two came from Access World Forums at: URL....

Code:

Function BACKUPS()
On Error GoTo Err_BACKUPS
Dim fso As Object
Dim sSourcePath As String
Dim sSourceFile As String
Dim sBackupPath As String
Dim sBackupFile As String

[code]....

I got a compile error "Invalid use of property." on the button sub. Then there was a simple On Click sub:

Code:

Private Sub Backup_Click()
Dim fs
Set fs = CreateObject("Scripting.FileSystemObject")
fs.CopyFile CurrentProject.FullName, "C:", True
Set fs = Nothing
MsgBox "Database has been backed up successfully"
End Sub
Private Sub Command32_Click()
End Sub

On this one I got a "Permission denied." error on the CopyFile method. As I said before, my database is not password protected.I found this third bit of code on another forum: URL...

Code:
Public Function db_Backup()
On Error GoTo db_Backup_Err

Dim sourceFile As String, destinationFile As String
Dim aFSO As Variant
Dim path As String, name As String

[code]....

On this one I got another "Permission denied." error on the CopyFile method. Again, my database is not password protected. This code had appeared to me to be the most promising of the three.
