Backup

I have posted a query before and solved the problem myself. What I am doing is using the filesystem object to copy my Access DB to another folder on my site for a backup. I then have a page that says when the backup DB was created, uses the filesystem object as well. My question is that when I backup the DB the page does not display the correct time and date of when the DB was last backed up. Here is my process for backing up the DB:

First I Delete a previous backup and lock the current DB

Then I copy the current DB to replace the copy I deleted

Then I un-lock the DB and return the user to the page that should show the correct date and time.
