People correct me if I am wrong but no Replication/Failover plan exists for this as of now. You can restore to Azure which would be a v2v. Then create backups with Veeam Azure appliance with blob repo and link with an external repository at a VBR on premises I believe the restore in the other direction. Not automatic but better than nothing.

Yeah! You right Geoff. Its not possible replicate workload between on prem and cloud environment only with Veeam.

Microsoft has VMware on Azure that I presume that you can deploy vCenter over Azure.

Yeah, that is definitely the case here.  No replication/failover to Azure within Veeam right now.

You cannot replicate /failover between on-prem and Azure.

You can restore the VM to Azure from on-prem. But there are some limitations.

If you want to restore a VM from Azure to on-prem, you need to use Veeam Backup for Microsoft Azure to backup the VM of Azure and then perform instant recovery to restore it to on-prem.

Only thing to add to this is you can use Veeam Agent Backup for cloud machines to avoid deploying Veeam backup for Microsoft azure

You might find this easier to use for your failing back, can even use Veeam Recovery Orchestrator to assist with some of this then.

I did not know that you can now user Recovery Orchestrator for that!!

By the way folks, always a good idea to remember about egress/ingress charges with cloud providers. I am not sure what Azure does but I remember there was always a concern about that. I think that is one of the reasons I used an appliance once, kept non critical VMS only in the blob storage, backup copy jobs out to other location. Again can’t quite remember but the going out I think is where they charge.
