if you are running Hyper V on premise you could use Azure to host the replicas. Previously, you needed System Center Virtual Machine Manager to configure this but now no more.
As you can see from the above screen shot once you have created your Azure Site Recovery vault you can select to setup recovery Between an on-premise Hyper-V site and Azure.
Can’t say that I have done this or really intend to but the documentation to achieve this is all here:
Getting Started with Azure Site Recovery: On-Premises to Azure Hyper-V Site Protection
Give it a go and tell me what you think!
