Cardano-node always running?

When trying to backup my Daedalus wallet I couldn’t copy/paste the events and checkpoints files because they were in use by the cardano-node. Even when Daedalus is closed I noticed that the cardano-node is running in task manager. Is this supposed to be like this?

I re-booted the computer and the cardano-node is no longer running. If I open Daedalus the cardano-node runs and stays running even if I close Daedalus.
