Bobby Petta earned Darlington a crucial win when he marked his debut with the only goal of the game at Bury.
Petta, playing his first match since last April when on Fulham's books, cheekily chipped Andy Marriott midway through the first half for the winner.
Alun Armstrong came close to adding a second, heading against the post.
Early on, Bury's Jon Newby and Andy Keogh forced saves from Quakers keeper Sam Russell. Simon Whalley also missed a great late chance for the Shakers.
