Hyper-V replication licensing

Bringing stupid issues as this up.
You brought it up and didn't explain why you were recommending doing something mathematically risky. I didn't bring it up at all. Nor did @JaredBusch we only pointed out that buying an extra license was totally unnecessary and would just be a waste of money.

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.
Scott your insulting hobbyists. Most of the OS instances in my house are virtual. My home datacenter looks down on their business practices.

That's why I said, only low end hobbyists. Any serious hobbyist would obviously be virtual, and backed up.

I just showed up to say you are all wrong
They should buy Software Assurance which will let them migrate that license back and forth whenever they want at a lower cost than buying a full stand alone license.

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.
Not in 99.999% of cases. Remember you are talking about a double failure, not a single failure. So let's run the numbers assuming a single license is $700.
For 90 Day Failover Window Licensing Cost: $700
For Sub 90 Day Double Failover Licensing Cost: $1400The drug you are looking for is failing over to reduce maintenance window times for host/hypervisor patching every patch Tuesday (assuming Hyper-V).

Yup, way better than a second license. But easily still not worth it based on this risk alone. Even if the business was making a million an hour (which would make them a Fortune 100) it's only worth a few hundred bucks to mitigate this risk alone. SA might be worth it for lots of other reasons, I'm an SA fan generally, it would have to be really cheap to make sense here just from the ability to fall back really quickly. But with the other benefits, is easily the way to go.

Yes, very true. If there is a need for scheduled downtime, that would be very different. That would easily justify the cost, but few SMBs are hit by that. More than are hit with the 90 day problem, but still pretty few. Since you need scheduled downtime for the OS anyway that can't be avoided through any means in these scenarios, it's can't be a significant deal.

@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.
If you are using replication for DR, then yes you need the second windows license. Because the potential for migration is always there.
If you are failing over manually. Then you can get away with one server.
But I have to ask, if you are dropping a few grand for the hardware, why would you not spend the extra on the second License and have HA setup?

When did that SA benefit get added?

Even replicating for DR, doesn't imply that you set it to start automatically. And even then, it's only migrating BACK that triggers the need for a second license.

Because you can have HA without spending that money AND in most SMBs that's still a lot of extra money.

Agreed, it the automatic fail situation that as I understood from the Microsoft green guy at MS. That required the extra license.

So what... You setup autofailover, then when you see a failover you then disable that until the 90 days is over?

Yup, that's one way. If you are doing Hyper-V Replication, though, there isn't any means of failing back as the replication is one way, so nothing more to do.

Really? So once it's failed, and you repair the other box, wait 90 days, then you have to configure replication back the other way?

Yup. That's how one way replication works
And since this lines up with the licensing, keeps you from accidentally violating the license naturally and is the logical way to do this anyway as you wouldn't want to migrate back until there was another failure, it works pretty awesomely. -
Or just buy a second license and do whatever the hell you want.
Or, like probably like 95% of people do, say "That's a bunch of crap" and just do what you want.

I never expected the thread to blow up while I was away. I meant two servers are needed for the remote office. A domain controller and a file server. Corporate IT insists that the DC and FS be physical. Corporate says only physical servers are allowed because virtual servers are too risky. Since they obviously aren't following best practices, I was trying to make a business case out of virtualization and wondered if we could save $600 on the license of Windows. I was proposing taking their hardware and only buying one Windows license to come out $600 ahead and have a redundant system instead of having production go down if either one of their servers fails.
-
I agree that in the big picture of their infrastructure $600 isn't much, but this has been an interesting group to work with. I could share a few examples of some of the stuff that they said over the last couple of days, but I don't need to berate anyone, I need to have a talk with the business manager and show them how their IT is making bad business decisions.

Yup. That's how one way replication works
Yes, it may be technically how it works.
But no, that is not how it works as a system. The system handles it all for you.
Note that the primary and replica servers are now reversed.
