`mongodump`

- Specify an output location for the dump:

`mongodump {{[-o|--out]}} {{path/to/directory}}`

- Create a dump of a given database:

`mongodump {{[-d|--db]}} {{database_name}}`

- Create a dump of a given collection within a given database:

`mongodump {{[-c|--collection]}} {{collection_name}} {{[-d|--db]}} {{database_name}}`

- Connect to a given host running on a given port, and create a dump:

`mongodump {{[-h|--host]}} {{host}} --port {{port}}`

- Create a dump of a given database with a given username; user will be prompted for password:

`mongodump {{[-u|--username]}} {{username}} {{database}} {{[-p|--password]}}`

- Create a dump from a specific instance; host, user, password and database will be defined in the connection string:

`mongodump --uri {{connection_string}}`
