Does the hot backup function back up data written during backup

Hello, @zengwb

Few days ago we updated our documentation page for hot backup. One of the changes is related to your question. Here is quote of the new text from that page:

The backup taken is the snapshot of the mongod server’s dataDir at the moment of the createBackup command start.

So the answer to your question is “no, it doesn’t”.
