There's reserve tanks or more generally reserve fuel for emergencies. Other than that there's no propulsion backup for when the fuel runs out, instead redundancy comes from multiple independent fuel tanks.

And in larger aircraft, multiple independent engines. See for instance ETOPS

From the pictures, I see that this new aircraft has 4 engines.
