Recreating database for media content

Hey guys!

I just migrated one of my WordPress pages to a multisite WordPress installation.

With the exported backup I, however, couldn’t get the media files (images and galleries) back up. What I did then was just copy all the content from wp-content/uploads to my new server.

WordPress however doesn’t automatically reload them, because apparently it creates a database entry for each uploaded file. Now I’m wondering, since I have a backup of the old database, which table I need to import into my new database to have the Media tab in my Dashbord show the images and galleries again? Is there such a way or do I need to upload them by hand again and create all new galleries?
