How Do I Restore Just the Settings From Database

So the other day, while I was sleeping my site inexplicably lost all of its settings. I have a feeling that another admin accidentally updated the theme, but that is neither here nor there. I have a backup of the database, but it is a multi-user site and items have been added to the database since the mix up. My question is, is there a way that I can restore just the settings from the backup or do I have to restore the entire database. Sorry if this is a redundant question, I searched the forum but couldn't find this answer. Thanks in advance for any help.
