In 1997, SG-1 visited the planet Altair where Harlan created android duplicates of them. Eventually, Harlan let SG-1 go and the android version of the team agreed to bury their Stargate. Despite this, they eventually began going out on missions of their own and fighting the Goa'uld as the human version of the team does. (SG1: "Tin Man", "Double Jeopardy")
