We recently had one of our servers crash. The server (Server1) was running 2008 R2. It was a domain server and the only backup that we had was from 3 months ago. Since the time of the last backup we added another server (Server2) and enabled replication from the first. The question is that if we restore the backup from 3 months ago, will it overwrite Server2 with old data? What is the best procedure to restore the old backup and get the updated Active Directory information on it from Server2..
