 Description   

In regards to: http://mms.mongodb.com/help/backup/tutorial/enable-backup-for-sharded-cluster/

At present our explanation for what a Cluster Checkpoint is is:

A cluster checkpoint is a valid point in time when a sharded cluster can be restored. You must pause the sharded cluster balancer to create each checkpoint.

We should expand on this to explain/clarify the following:

  1. We state "You must pause the sharded cluster balancer" - The "you" implies to me that we expect the user to do this. We should reword to be clear on the source of the pause.
  2. Cluster checkpoints are light weight - requiring oplog token insertion on mongod and configdb instances. We should clarify this as being light weight also means negligible backup-charge cost for the cloud and negligible disk space for on-prem.
  3. Our default for checkpoints is disabled. We should explain why - meaning what are the downsides of enabling (like a short disruption of the balancing process for example).
  4. There has been confusion as to whether checkpoints are required in order to have a restorable sharded backup. We should state clearly that they are there to allow for additional points in time that can be used for restore.
