/path/to/mongodump -d your_db --username db_user -p -o /your/backup/path/mongodb/your_db-mongodumpTo backup MongoDB database using the gzip option:
mongodump --db your_db_name --gzip -o /your/backup/path/To Restore the database when using gzip option:
mongorestore --gzip --db your_db_name /your/backup/path
