How to restore a virtual Domain Controller with Cyber Backup 12.5 on another ESXi server?
I am currently trying to verify backup / restore in an ESXi environment with Windows Server 2016 operating system VMs.
I created an agentless backup of the virtual machines including the domain controller, for the domain controller I activated application backup for Microsoft active directory. No errors happened during backup.
To verify the restore procedure I restored all the machines to new VMs on another ESXi server. In theory the restored VMs should be identical to the old ones. But obviously the domain controller is not, it does not allow login any more. Consulting the documentation it seems the restored domain controller assumes it was cloned and thus prevents startup of active directory. The other machines do come up and allow login but do not have DNS or AD.
How can I restore the whole system including the domain controller in case my ESXi server hardware is lost and I have to restore on another ESXi server?
Update: The answer to this is to shut down the Domain Controller before backing it up. There seems to be no way to get a consistent hot backup from a DC. With a hot backup the DC will go into Directory Services Restore Mode after restoration to a different VM. I assume even a restore to the same VM will have the same issue.
So despite application backup for Microsoft active directory do not use hot backups from the domain controller.
If you have any other experience, please let me know.
