Does Elastic DRS failback only copy the delta when restoring to the original server?

Question

I've found a references to the mass failback client for DRS supporting delta changes when failing back to VMWare: https://youtu.be/7sxL8Oy4EpE?t=270. My question is, does the ISO failback client also support just copying the changes back when doing a failback to the original server that was failed over to in AWS?

Yes, if you Failback using ISO to same original server then replication will sync only delta changes which happened on AWS Recovery server.

However, there is a feature in AWS DRS called "Non-disruptive failback testing" through which you can Failback to a different new server and in this case, entire data from AWS Recovery server will be sync'ed back to the new server.
