Server 2012 hyper-v replication RRS feed

  • Question

  • hello,

    we currently replicate our DC to a hyper-v 2008 server using Double-Take.  The VM lies powered off during replication and can be powered on when failover is required.  I want to upgrade the hyper-V server to 2012 and then use the new built in replication tool to replicate the VM across to another offsite 2012 server.  My question is does the VM have to be powered on to replicate between two 2012 hyper-v servers?  this would not work for me as I need the VM to be powered off to allow for the Double-Take replication.  Another issue might be that Double take process might prevent hyper-v replication in the first place.

    Thanks

  • No, source VM does not have to be powered off.  For details on Hyper-V Replica see https://technet.microsoft.com/en-us/library/jj134172.aspx

    Don't know how Double-Take will affect your environment.  If you are using it just for DR, you may be able to get by just with Hyper-V Replica.

  • I have not worked with Double take in a long time. I am not sure how that would play along with Hyper-V replication or if you can even use them at the same time. In my last Hyper-V replication setup, the backup site was off while the primary was on. During failure of the primary, the backup would come up automatically and take over. During fail back, the backup would update the primary before shutting back down so that no data was lost.

  • hi

    I need both the hyper-v source and target VM to be off.  I cant have the source on.

    thanks

  • I have only done that with third party replication tools. I don't think you can have both sides off and have Hyper-V replication still replicating the data. I might be wrong. You could probably do that with DFS replication, but I am not sure if that is a good idea and it also would not include any sort of failover mechanism. It would just replicate the data between the two volumes.

    Maybe that is what you need?

  • "I need both the hyper-v source and target VM to be off.  I cant have the source on."

    That's strange.  Generally when people are using some sort of replication technology to a DR site, it is so they can have a relatively current copy of the running environment.  I'm pretty sure Replica will also replicate VMs that are not on, but the general model is to replicate the changed state from a running VM in a primary site to a backup VM that is off in the DR site.

    I'm curious.  Why must you have the VM off in the primary site?

  • Hi Djespley,

    >>I need both the hyper-v source and target VM to be off. I cant have the source on.

    Do you mean the source VM is always off?

    If yes, since the VM is always off and no changes are made, why you want to perform the replication.

    If not, you may manually shutdown the VM when you want to perform the Double-Take replication.

    Best Regards,

    Leo
