This must not working at all. Because when you perform an unplanned failover on vm on replica server, the replication status of the replica server will be ‘ FailedOverWaitingCompletion’, then primary server’s replication status will be ‘critical’ as it lost data sync with the replica server. So what should we do next?

Hi,

Very interesting post. Do you know what are the benefits of the compression?

Thanks

In reply to Leonard. I would recommend you to use the build in feature of Hyper-V Replica to save the media on a disk and import it on the other Hyper-V host

Great Arcticle !!!!,

Need help on mentioned Case…

Need help to open Port 80 for Hyper-V Replica

We have Setup Windows Cluster 2012 Failover Cluster in Both Sites ( primary and DR) with the help of mentioned links.

https://www.thomasmaurer.ch/2012/07/hyper-v-replica-the-game-changer/

http://kristiannese.blogspot.in/2012/03/hyper-v-replica-by-example-part-one.html

Now, We want to cross-check Hyper-V Replica functionality but it is saying that Port 80 is not opened, Need Suggestion on same.

Windows Firewall inbound rules is already set as per above links.

Question: From where to where we need to open port 80 means which nodes/cluster/Hyper-V Broker ? As per mentioned cases.

Like,

Case 1. From Hyper-V broker of Primary Site to Hyper-V Broker of DR Site

Case 2: From Physical IP Address of Both Servers at Primary Site to Physical IP of Both Server at DR Site.

Case 3: From Cluster IP Address of Primary Site to Cluster IP of DR Site.

Case 4. From Physical IP Address of Primary Site to Hyper-v Replica Broker of DR Site.

Case 5. Port 80 need to open between Both End for Physical IP’s, Hyper-V Replica Broker and Cluster IP.

Kindly suggest on urgent basis.

Note: It is working fine in same IP Subnet, only change with different Subnet.

Thanks
Kirpal Singh

Sorry I missed one question, the maximum of Hyper-V Replica recovery points are 15.

In reply to Fred.

Hi Fred

First if you choose a Recovery Point for the Failover which is not working or has some other problems you can still change to another Recovery Point. All Recovery Point are saved as Snapshots. I have updated the post and you can find a screenshot under Familover.

For the Performance Part I will write another blog post :) I hope I could help :)

Interesting post. Thanks for it.
How many recovery Point in times can be chosen? Is there any performance impact?
When I failover, how to I choose which point in time to choose to spin up the VM? What if I choose a wrong one?
Its an interesting feature but I need to know the impact before using it.
Thanks.
