mongodump and mongorestore cannot be part of a backup strategy for 4.2+ sharded clusters that have sharded transactions in progress,

if you don’t use cross-shard transaction, it’s ok to use mongodump. I can’t find where the mongodb official doc says writes have to be stopped to use the tool. If you have such reference, pls share a link.
