I have an Access database that I want to automatically make a backup copy of it daily and place the copy in a different directory.  Just, wondering, is this doable in VB application?  If so, how do I do it?

Thanks in advance.

You could just as easily do it with a batch file, but VB could certainly do it as well.

1) Are you wanting your backup "app" to be running constantly, and then make a backup when it sees that it is time?

2) Do you just want a backup whenever you bootup?

3) Do you want to use "Scheduled Tasks" in windows to run your backup app at a specified time?

Many options...let us know.

I want to run at a certain time say 10AM.

I wrote a batch file to do this, but somehow it doesn't work.  I mean, it does work, but I don't know what happen recently it doesn't work anymore (http://www.experts-exchange.com/Operating_Systems/MSDOS/Q_20797170.html).  That's why I'm writing it in VB.

Hi James,

If this is a plain Access  MDB file you can copy it with the copyfile API function.

Just declare it like this:

Public Declare Function apiCopyFile Lib "kernel32" Alias "CopyFileA" (ByVal lpExistingFileName As String, ByVal lpNewFileName As String, ByVal bFailIfExists As Long) As Long

Then call it from your program using something like this:

CopyFile Serverpath & "System7.mdb", "C:\Adir\Client.bak"

In this example System7.mdb represents the access data file
Client.bak is the backup copy

I suppose you could get your program to check the system time and back up at the same time every day.

The beauty about using the Copyfile function is that it will allow you to copy a file whilst it is still open.

Better thing is to create another program to take care backups,cleanup stuff etc. In that program you can allow the users to customize the backup time, etc., Make sure the program is running for 24 hrs.
