I have created two Protection groups, one configured as individual computers (Group A) and one that is Active Directory enumeration (Group B). I added the failover cluster nodes individually into Group A, whilst I added the failover cluster computer account from AD into Group B.
Then I set two jobs, one as server backup (Job 1) VBR managed the other as Failover backup (Job 2), I added Group A to Job 1 and Group B to Job 2 and launched a backup of each, one after the other. However, both backups are identical,there is nothing extra from the failover backup that isn't in the standalone backup. Which prompted me to ask the question "What is the difference between backing up individual nodes within a cluster and the cluster itself?"
The cluster currently has a file service role. However, we are planning to use Veeam agent within VMs that have RDMs and are running an MS SQL cluster. We don't need to backup the MS SQL as there is a SQL Job that does this and dumps the backup to a drive, we only need to backup that drive. So, is there any benefit by setting up Failover Cluster backup as opposed to individual nodes?
