Create mongodbs backup and restore for apps deployed using meteor up?

What’s the standard procedure for creating database backup and restore for apps deployed using meteor up?
Thanks

Seek keyword mongodump.

@Steve : Yes, I want to use mongodump. But how?

So the command to backup db using mupx is

docker exec -it mongodb mongodump appName

to be entered on server

@nikhildaga

I just ran

docker exec -it mongodb mongodump

I tried first with

docker exec -it mongodb mongodump appName

but it didnt work

But then without appName it worked

It made the dump

But to where?

Was the dump inside the docker container? How do I get the files?
