We are implementing a disaster recovery protocol for my company in case of tornado, fire, flood, or any other catastrophic event. We are a small company.
I have two physical domain controllers. One is primary and other is backup. I was wondering if it was a good idea to create a third. However I wanted to make it a virtual domain controller.
My thoughts are that if there was ever a fire or flood and all my physical machines were destroyed I could be up and running quicker because all of our production servers are virtual.
I would just need to get a new virtual host, delay start all of the other physical machines, promote a new physical domain controller from the virtual one, get some workstations and we could be up and running in 24 hours at a temporary location.
The virtual machines are backed up weekly and kept off site. Is this possible or would my network be screwed up given the loss of the physical domain controllers?
Or would it be better to just do active directory backups regularly and do a restore on the new servers?
I'm looking for the cleanest easiest option. Everything is 2008 servers R2 standard and enterprise editions.
