My client has a one year old Server 2012 R2 running native Windows backup to external USB backup drives. Bitlocker is NOT enabled for anything on this server. A backup drive has been stolen and I am trying to find out what data is available to someone looking at the drive without access to the server itself. I am assuming that the thief does not know the server password or details of how the server was configured with drive letters, etc. What concerns should I have regarding the data on the backup drive?
Thanks!
