    [ https://issues.apache.org/jira/browse/ARTEMIS-2930?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17208144#comment-17208144 ] 

Justin Bertram commented on ARTEMIS-2930:
-----------------------------------------

What do you mean by, "the slave node keeps polling the new data at a regular interval"? Can you cite the specific documentation you read?

I don't understand why there is a "100% chance" of data loss? If you send a durable message to the live broker in a live/backup pair using replication then that message will be replicated to the backup before the live broker tells the producer that the message was received. Therefore, the producer can be confident that if the "send" method returns both the live _and_ the backup have the data and there is no chance for message loss.

> In the documentation I read that the HA with replication strategy, the slave node keeps polling the new data at a regular interval.
> So, there is 100% chance that delta messages are lost if the master server is down.
>  
> How to overcome this issue and ensure that there is no data loss in any condition while using HA replication strategy.
