meteor mongo is helper script specific to applications deployed on
meteor.com or on your dev env when you are running an app via
meteor run. It allows you to connect locally from the directory you are running in via
meteor mongo
If your app is on AWS you must have released it via bundle and running it as a node application?
If so you must have passed the mongo url as an environment variable?
So, you wouldn't use meteor mongo command but just use the regular mongo cmd line tools that ship with it.
Or are you deployed on AWS as just a meteor app and you didn't bundle it and are just running it?
If so then you just go into app dir and
mongocommand --host 127.0.0.1:3002 --db meteor
So, something like this to restore and use mongodump to dump
Though, hopefully you bundled and deployed on AWS. Which if you did just connect to where ever you put your mongo installation, either on that machine, another machine or someplace like mongohq/lab.
