Netbackup BMR Restore error "Failed to retrieve server configuration"

Question

I am attempting to restore an image to a VM (Hyper-V) server 2012 and get the error "Failed to retrieve server configuration" when attempting to retrieve configurations.

I think there is a driver issue since the Boot server for Server 2012 is a physical machine and I'm trying to restore to a VM.

Troubleshooting steps so far:

- Created a new client configuration and entered the MAC address of the new VM and this still failed.

- Tried Generic BMR restore rather than Automatic

If this is a driver issue where can I get the Hyper-V or VM drivers to download?

Any assistance is appreciated

AFAIK, a DHCP server is only required at two points... 1) at PXE boot time &nbsp; 2) when the recovered VM actually boots, but only if you choose not to keep the IP permanently that you entered during BMR client "contact the master server stage".And again AFAIK, but I could be wrong, the master server will only respond to a BMR client if &nbsp;the MAC and IP addresses both match a valid BMR "config" that has already had "prepare to restore" actioned.My guess is that as a test of the BMR process, that you are possibly attempting to clone a VM, whilst keeping the original VM up and running. &nbsp;This is perhaps the trickiest of the BMR pathways. &nbsp;Here's what I would do for testing, to gain experience and confidence with BMR, go for the simplest test first, which is... recovery of exactly the same VM... so, I would power-down the live VM and keep it safe. &nbsp; Create a new VM but give it exactly the same MAC address as the original, and give it exactly the same number of disks and DVDs in exactly the same SCSI order and of exactly the same size as the original VM. &nbsp;Now you no longer need to mess about with creating a different "BMR client config" on the master, or messing around with disk mapping, just choose the client's default BMR config and "prepare to restore".

That would probably point to a failed network driver i.e the client failed to contact the master server to retrieve the configuration. You'll need to add the drivers used by hyperv&nbsp;into the configuration you create when running a prepare to restore.

Thanks. I figured as much. Question is do I download the driver for the hyper v host and add it to the SRT? would it be available in the integration services?

Hi,
&nbsp;
Yes, I'm not certain what the latest method is, in version pre 7.7 a WIM file was used so there was quite a convoluded method of mounting and modifying this WIM file using some MS tools.
Since 7.7 the WIM file is not used, we use the regular installation media (same process as other OSs)
I suggest downloading the BMR guide for the version you're on.

So I confirmed that NetBackup BMR 7.6.1, the version is WinPE 5.0, which is based on Windows 2012. Does this mean I have to use the WIM?Also, does it matter if a DHCP server is required when performing the restore?
