To add a Microsoft Hyper-V environment in Portal, you must install a Hyper-V Agent and provide credentials for the Agent to authenticate with the Hyper-V environment that you want to protect. You can then back up and restore virtual machines (VMs), without installing Agent software on individual VMs.
The Hyper-V Agent concurrently backs up multiple VMs in a single backup job. In a cluster, backup operations can be distributed across nodes, making the solution scalable in large environments. Within a Hyper-V cluster, the Agent can back up VMs that have migrated to different nodes or to different storage.
You can include multiple VMs in a single backup job, but each VM is backed up as a separate task on the vault. As a result, each VM has a single backup history, even if it is moved from one backup job to another over time.
Each VM is independent from the job in which it is backed up. When restoring a VM, you do not need to remember which backup job it was in. You can restore a protected VM even if its backup job has been deleted.
The Hyper-V Agent is closely integrated with Portal. You must use Portal to manage the Hyper-V Agent, back up VMs to a secure vault, and restore VMs. The Portal instance can be hosted by your service provider or installed on-premises.
