Backgrounds have no quantifiable mechanical effect. They explain stuff your character might (subject to role-playing and DM adjudication) be able to expect in their interaction with the world. So it can give you other ways to get lodging, connections, information, food, even potentially gold. What it wouldn't do, though, is give you any pluses, extra proficiencies, advantage on rolls, or anything else that might be granted by other character build space.
I think [MENTION=6677017]Sword of Spirit[/MENTION] may have meant background features, not the whole backgrounds themselves.
