We have an installation of 2 physical Domain Controlers (Windows 2008R2) – 1 is Fileserver, Printserver etc. and 1 is Exchange server 2010 – both DNS and DC.
Furthermore we have 3 x ESXI 5.5 hosts (Vsphere Essentials) – 1 of those is used for backups of the 2 DC’s (Virtual copies done with VMware Converter. None of the monthly backups have never been online or started.
The intention was if one or both of the DC would break down, we would have the virtual copies that could be taken online and patched with the latest daily (Novabackup) and then have the domain back online to serve the users.
Today I came across some whitepapers that state that virtualizing DC’s from Physical servers is not recommended. None of the conversions have ever logged any conversion errors.
I would like to ask you guys if any of you have a step.by-step recommendations for a backup type (security) for the above mentions scenario or even a better way to secure the AD by having Virtualized copies offline. ??
The physical servers are now 4 years old:
HP Proliant ML310 G5 – Hardware RAID 1 – 2 discs 1 spare (DC, Fileserver, DNS, etc.)
HP Proliant ML350 G6 – Hardware RAID 5 – 4 discs 1 spare (DC, Exchange 2010, DNS)
