There is no facility in Veeam to do this that I am aware of and you require the bootable media to restore an OS from backup.

​@sparrowhawk have a look at this article, I think it will be useful for your needs. https://helpcenter.veeam.com/docs/agentforwindows/userguide/volume_restore_disk_mapping.html?ver=60 

I agree with Chris. What I did in the past - this is clearly experimental - was creating an inidiviual multi-boot ISO with a “menu” that made you able to select between multiple boot images. The first one was the recovery media from Veeam, the second one was a Windows ISO.

Basically you don’t come around a recovery media as far as I know.

maybe also an option for you:
Nico Stein has written an article about integrating the Recovery Media into your boot menu - in this way you dont have to create your media in case you need it, you could access it, on every boot:

Thanks for all the information guys, this is really helpful. ​@Dynamic’s suggestion is interesting and is probably the closest to what I’m looking for. We don’t have easy physical access to the server so I was looking for a way to have a bootable backup ready to go with minimal downtime.

But I’m now thinking that as this server is providing DHCP, that configuring DHCP failover would be a better way of minimising the impact of drive failure.

I’m still reading up on recovery strategies using Veeam though, but I see that some form of recovery media is required.

Thanks all!

Thanks for your reply ​@sparrowhawk!
