### Can I protect VMs when Hyper-V is running on a client operating system?

No, VMs must be located on a Hyper-V host server that's running on a supported Windows server machine. If you need to protect a client computer you could replicate it as a physical machine to [Azure](./vmware-azure-tutorial.md) or a [secondary datacenter](./vmware-physical-secondary-disaster-recovery.md).

If you want to replicate to a secondary datacenter, then Hyper-V VMs must be on Hyper-V hosts servers located in a VMM cloud. If you want to replicate to Azure, then you can replicate VMs with or without VMM clouds. [Read more](./hyper-v-azure-tutorial.md) about Hyper-V replication to Azure.

Yes. Site Recovery converts from generation 2 to generation 1 during failover. At failback the machine is converted back to generation 2. [Read more](https://azure.microsoft.com/blog/new-azure-migrate-and-azure-site-recovery-enhancements-for-cloud-migration/).

127
134
You can replicate any app or workload running a Hyper-V VM that complies with [replication requirements](hyper-v-azure-support-matrix.md#replicated-vms). Site Recovery provides support for application-aware replication, so that apps can be failed over and failed back to an intelligent state. Site Recovery integrates with Microsoft applications such as SharePoint, Exchange, Dynamics, SQL Server and Active Directory, and works closely with leading vendors, including Oracle, SAP, IBM and Red Hat.

### Is failed over data resilient?
230

221
231
Azure is designed for resilience. Site Recovery is engineered for failover to a secondary Azure datacenter, in accordance with the Azure SLA. When failover occurs, we make sure your metadata and vaults remain within the same geographic region that you chose for your vault.

[Failover](site-recovery-failover.md) isn't automatic. You initiate failovers with single click in the portal, or you can use [PowerShell](/powershell/module/az.recoveryservices) to trigger a failover.
