Restore from .gz backup / mongorestore to create new DB from .gz backup files
Taking a backup of stage and restoring it to our local database is a common practice followed to test and replicate any issue found on stage or prod. Due to data being transferred from the different channels the team which creates backup or dump of stage/prod DB provides backup as zipped data. So when we restore from .gz backup it becomes more important to unzip data before it gets created to our local mongo store.
