We use Veeam for backups. We are working on moving away from tape. We are going to go to our own offsite disk, or cloud. Having a functioning domain controller is absolutely necessary for everything.
We have two DCs at headquarters. We have several satellite branches that we could utilize for DR. We don't have a ton of bandwidth. 10Mbs of fiber internet at headquarters, and we could match that with coax internet at the DR site.
In the event that headquarters is wiped out.....
1. Should I restore a backup copies of our DCs at the DR site.
2. Or...Should I just spin up a third DC at DR now and simply promote it if headquarters is gone.
