Hi Marc,
Go into Moodledata > Repositories inside the WAMP server file system
Make a new folder called "Backup"
Put your MBZ file in there
On the moodle go to Site Admin > Plugins > Repositories > Manage repositories
Enable "File System" and then go to the settings where there will be a drop down with "Backup" in it, select that and save.
Now underneath "Wikimedia" you will have a new link called "Backup" and you can access you backup file from there.
Hope that helps
Charlie
