On one of my sites I have a 2-CPU host covered by Veeam B&R licences.
I've just added an additional 1-CPU host for resiliency and formed a cluster with the existing 2-CPU host.
All the VMs will run from the 2-CPU host once I change them from standalone VMs to clustered VMs, I'm going to set the 2-CPU host as the preferred owner.
I don't have any requirement to be able to take backups from the new 1-CPU host as this is only there to keep the VMs running during updates/reboots of the main host. The backups will be timed such that they are finished before the main host reboots.
I am concerned that if I add the cluster to Veeam I'll get a licence warning/error. I don't really want to licence the new host as it is only very rarely going to have anything running on it.
I've moved one VM under cluster control and am now getting the following warning during it's backup: "Failed to flush change tracking data. Using full scan incremental run.". The VM had been previously backing up with no issues so I'm fairly sure it is something to do with it now being clustered that's caused this.
Should I reconfigure Veeam to talk to the hosts as a cluster, or just keep the original host configured as a standalone host?
