Single Site Active Directory

Replication using DoubleTake is supported.

Multi Site Active Directory

Microsoft Domain Controllers should NOT be protected via DRaaS.  This is due to the potential for corruption, clock drift, isolation and more in Active Directory.  It is, moreover, easy and simple to have a DC on the recovery side so there is no need to replicate it and recover one. 

Requirements

There needs to be a dedicated Domain Controller living on the DR network that is synchronized via Microsoft AD sync only to the production AD servers.
