Method and licensing for virtualization on disaster recovery server
Posted on 2011-09-22
Our customer has 2 servers - 1 running SBS 2011, the other running Windows 2008 R2 which is used as a terminal server for remote access and internal application publishing.
We would like to setup two virtual machines on an external server that their users can connect to in the event of a disaster situation.
My thought is that we can take a machine image of each server offsite. Their data is already backed up offsite on a daily basis. So we could restore the image plus incremental backups to a virtual machine and have all users connect from their home PCs using terminal services.
As I understand it, a Windows 2008 licence covers you for one physical and one virtual machine - do both have to be used on the same physical machine? i.e. does their current 2008 licence cover them for having a virtual machine at another site?
And what's the score for SBS 2011?
Similarly, if they have TS CALs on the physical server - do we have to buy additional CALs for the virtual server - even if the virtual server is never running at the same time as the physical one?
