Mongodb sharded cluster backup

Question

I have a sharded mongodb database cluster. I am using mongodump utility to take the backup.

mongodump --host <host> --port 27017 --db <db_name>  --authenticationDatabase admin -u <username> -p <password> --out ouput

Will I be able to take the backup of the entire database by running the above command against my mongodb router?

Tried running the above command.
