Quick VM Restore on HyperV - Free Vembu BDR

Vembu-VMBackup

Hi, need some help.

Free Vembu BDR is installed on virtual machine with Windows Server 2012 - it is located on HyperV host, let's say HyperV-A. Simple configuration, added storage pool, added another HyperV host (let's say HyperV-B), Vembu Integration Service is installed on it, backup job is running well, everything is fine.

But when I want to use Quick VM Recovery on HyperV-B Vembu says: Error: Hyper-V role is not enabled in this server to do Quick recovery. Please enable Hyper-V role and then try again

So... What is trying to tell me? That I should install Free VembuBDR on HyperV-B host, and manage all servers from that? It does not make sense, because what if my HyperV-B host will down? How will I manage my backups?

Please let me know, how it really works.

This Error message will show if you don't have Hyper-V role enabled on your Vembu BDR server machine and it is not specific to the free edition of Vembu BDR.

Quick VM Recovery allows you to boot the backup data as a virtual machine on the Hyper-V, KVM or VMware ESXi directly from the backup storage repository. So, to instantly boot the VM in Hyper-V, the Hyper-V role should be enabled in the machine where you have installed the BDR backup server. Also, if you would have installed the BDR backup server on the Ubuntu machine, you need to install the KVM to perform the Quick VM Recovery. If you are planning to use ESXi host for Quick VM Boot, you can instantly boot the backed up VM directly to any ESXi host over the LAN.

The concept behind the Quick VM Recovery is, Vembu reads the backup data from storage target and creates VMDK, VHD, VHDX and IMG files virtually on the VembuVirtualDrive of your BDR backup server. If you have enabled Hyper-V role your Vembu BDR Server machine, it can be used to create a Virtual Machine by reading the virtual disk files(VHD or VHDX) from VembuVirtualDrive.

Since you have installed Vembu BDR Server on a Virtual Machine, Hyper-V role cannot be enabled on it.

If you have installed Vembu BDR server on a Physical windows machine, you can enable Hyper-V role on it and this can be used by Vembu BDR Server to instantly create a Virtual machine during a system crash or disaster.

However, you can still make use of Nested Virtualization to enable Hyper-V role on the Virtual machine where you have installed Vembu BDR Server or you can perform the Quick VM recovery on your VMware ESXi if you have in your environment.

Thanks for reply.

So you mean I should install Vembu BDR on my HyperV host when I want tu use Quick VM Recovery if VM get crashed? But what if HyperV get crashed?

For example, I have only one HyperV environment im my company. How to recover environment (on the same or new host) when I have installed backup software on primary HyperV host? 1. Repair host 2. Install HyperV 3. Install Vembur BDR and connect it to the already existed storage with backup files 4. Recover VM

This is recovery procedure? It is possible to connect new install of Vembu BDR to existing storage with backup files and then recover machine from that?

Please let me know

We always recommend you to install Vembu BDR Server in a dedicated physical windows machine, so you can use the native Hyper-V manager to boot the backup data using Quick VM Recovery. At the same time, we are not recommending the installation of Vembu BDR Server in any of your production host i.e Hyper-V host.

If you don't have any dedicated physical machine, you can install the Vembu BDR Server on a VM and setup nested virtualization to perform Quick VM recovery. However, we are exploring the possibilities to use the Remote Hyper-V host to boot the backup data, and you can expect this feature in any one of the upcoming releases of Vembu BDR suite.

The Quick VM Recovery is a temporary recovery option, you can permanently recover the backed up VM to the same or different Hyper-V host using the recovery option Live Recovery to Hyper-V Server

You can rebuild the Vembu BDR server if you have the backup data with you. Once the backup server is rebuilt, you can start the recovering the backup data for it. Refer the following KB article to rebuild the Vembu BDR backup server.
