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}}
