Hmm, let's see... copy and paste the code below
into a VB class and see if it answers to Your needs

.... let me know

Option Explicit

'
' This simple class will help You implementing an SQL Server (and MSDE)
' backup/restore, the class uses the object library SQLDMO to interact
' with the native SQLsrv backup/restore functions so You'll need to
' reference that object library.
'
' It must be noticed that (if backing up on a file), the specified path
' is interpreted as "local" to the machine where the SQL server resides
' unless the path is specified in UNC notation, so if from a client You
' specify "c:\sqlbk\somefile.bak", the file will be created into the
' "sqlbk" folder of the machine running the SQL server and *not* on the
' client machine, while using "\\client\sqlbk\somefile.bak" will achieve
' the needed result
