If I had a single Windows Server Standard license, and two hyper V hosts and set up replication for the two VMs on host 1, am I good as far as licensing goes?
No, the licensing allows you two installations on the same hardware (as VM's go). On the second host, you would need identical, unused licensing to be in compliance.
Not with replication, because the second node is not running. Storage does not need to be licensed or else you could not have backups on tape, every tape would need a license.
Unless you are willing to not fall-back to the failed host until 90 days have passed.
Correct, standard license is one failover every 90 days.

How good is the fail over for replicated servers? Is it like in a VMware cluster where you can have the VM spin up if it senses it went down on the other host?
You can only transfer licenses once every 90 days, to my knowledge, so if you wanted to be able to move back and forth between the host faster then that you would need to have another Server Standard license to cover the other host.
I'm not sure about the failover, I originally thought you needed SCVMM to do that but now I think Hyper-V server has that functionality as well.
But if you do, that's load balancing not failover in 99.999% of cases. That would be some extreme hardware failure if you had to move more often than that.

@Mike-Davis said in Hyper-V replication licensing:
They are saying that they don't want to virtualize the servers because of risk.
Make sure that you explain that this is backwards and it is never acceptable, ever, to not virtualize intentionally specifically because it is so ridiculously risky. Virtualization is there for protection, that's its benefit. Not doing so is being intentionally risky and reckless.

@Mike-Davis said in Hyper-V replication licensing:
They also don't like external USB drives for backup targets. They would prefer tapes and a tape drive. I suggested a rack mount NAS as a backup target if they don't like the look of a external USB drive. What do you all think?
Nothing wrong with tape on its own. But I would explain to them that this is a mismatch of needs. They clearly dont' see themselves as a viable business, but as a hobby (no virtualization.) If they don't virtualize, they can't reasonably say that they think this is a real business, they are SO far below the home line it isn't even discussable. No grey area at all, this is a hobby and a joke to their owners. Make that absolutely clear.
So having backups at all makes no sense given how little of a priority they see their own hobby to be (even a semi-serious hobby would be virtualized every time.) So why take backups at all? There is a mismatch of goals here.

From the way @Mike-Davis has explained it both systems will be "production" if one fails then the second will take over even when the other one is replaced/repaired.
NEver allow someone to refer to something physical as "Production". It just empowers them to think it's a viable option.

How did you get that from what I wrote?

I was referring to the new, proposed, setup not the current one.

My statement with needing 2 licenses is one license per hardware server. Which allows you 4 VM's total (or as desired) 2 VM's with the option to fail over outside of a Disaster event.
I honestly don't see how it could be misunderstood.

You are the one misunderstanding or maybe just conflating things.. @Mike-Davis does not want fail over outside of DR. So there is no point, reason, or legal need for a second Windows Server license.

@Mike-Davis Hyper-V replication works fine but there is no automated power on or failure detection. That requires you setup a cluster and use SCCM I believe.
I use basic replication at a number of locations and it works great.

Maybe I am not understanding the question at hand, but at post 6 @Mike-Davis mentions he has a client who "only needs two servers"
This to me (assuming physical) as is followed up in the same post would give them the licenses they need for 2 hypervisors (4 VM's or 2 VM's and fail over). Again assuming these are Standard licenses.

Hypervisors are free. He would be licensing the operating systems hosted on these systems.

That same post is where he stated that they will not be switching back and forth.

There is no licensing for replication in Hyper-V. There is no need for a Windows server license for the second server.

In what world does a server crash and burn, the systems are manually migrated, and when the original system is backup and running for backup purposes not get used?
If the original backup host fails in 90 days, the client is then on the hook to Microsoft. It's far cheaper to purchase a second standard license then to worry about it.

He needs two licenses if physical, only one if virtual.

Yes, I get this. But those VM's can't run on separate hardware. Nor can they be rotated back to repaired hardware until that 90 day window.

He needs two licenses if physical, only one if virtual.
And if they have two hosts (2 clustered Hyper-V servers) the client is better suited with having the Two Server Standard licenses up front. Rather than risk litigation with Microsoft about what is "Disaster recovery"

In most situations where you are buying two servers and only using the second for replication, you are accepting that once you failover, you have to wait 90 days before failing it back to the repaired server. That is the design of the setup.
If they want something else, then this is not the right setup.
But it is specifically what was asked.
