Backstrom started 41 games for the Wild during the lockout-shortened season. He went 24-15-3 with a 2.48 goals-against average, a .909 save percentage and posted two shutouts.
"Our first priority was to re-sign Nik," Wild general manager Chuck Fletcher said. "He's been a model of consistency over his career. We found a way to give him some security in terms of a three-year deal and in exchange he was willing to work with us in terms of our cap situation and give us a cap number that is very workable for not just this year, but going forward.
"It's a win-win."
