We're backing up out here.

Hi, What does "We're backing up out here" mean in this context? Does it mean: We're leaving this place ? Thanks for your help.

M - Feels like you've been the cleanup crew for me the whole time I've been in here. Toes, contusions... insulin shots.
S - Well, somebody's gotta do it.
M - I'm grateful. You ever think... in another life...
S - I won't be that woman, Michael.
M - I wasn't asking you to be. But it is something I wonder about. What if... Anyway, just wanted to make sure it was said.
S - Why do I feel like you're saying goodbye to me?
M - I don't know. I guess in a place like this, you never know which day is gonna be your last.
K - Sara, we're backing up out here.
S - Okay. You're set. I, um... I'm sorry about your brother.
