    Currently yes, with extended scheme due to 2008 R2 becoming a DC. This will change as when I get some down time I will probably move the roles.

    Both servers back up at file level to a NAS box. Also the VMs are backed up on the host machine which is then handed off to the NAS, you know, just in case. I need to get another NAS to mirror the first, then I am happy.

    Are you happy backing up the dc as a virtual machine?? would you run into problems if you need to restore it?

    Well if something goes wrong I have two options, either restore from the normal backup or revert to the VM snapshot. What I would do depends on the what went wrong.

    As both DC VMs are being backed up at the same time, you could restore both at the same time to ensure consistency.

    The main issues occour if you have multiple DCs, if the AD sync gets messed up by restoreing a previous backup if another server has been left on AD can tear itself to bits which is a pain to fix. In general there is no issue of DCs on VMs unless the VM host relies on one of its own virtual DCs, it is snapshotting that you really need to be careful of as it is a snap to restore a machine to an inconsistant (within AD) state with this feature.

    If restoring DCs in any environment is is best to use a good backup tool and then you can perform an authorotave restore of AD to one server which is forced out to all of them making them all consistant.
