Apache/PHP may hold persistent connection to DB so the DB file is open and you can not overwrite it. Try to restart apache just before copying DB file, so it will close any open connections. You just have to ensure that nobody will access database via web server immidiatelly after restart. Use some config file to check if the db can be accessed from php.
