I have one case where i create db for Daily data. I have some collections in this db which are sharded. My requirement is as follows: Create every day DB If There is a DB which is more than 7 days old take its dump in some location and delete it from live DB.
I have one question how can i check if chunk transfer/balancing was completed for this DB before taking its dump and deleting it. I am concern if i delete the DB whose chinks were not transferred completed will it corrupt my system
