we’re running on Commvault 11.28.69
Backup of VMs on a streched VSAN Cluster, where VSAs are deployed to both fault domains, enabling the use of hotadd transport mode in both locations.
The backups are currently assigned to any available VSA, without honoring the fault domain. This creates additional WAN Traffic and also has an impact on backup performance.
According to BOL this feature is available since 11.20
I also defined bEnableClusterFaultDomainDispatch = true (should be default) on all VSA, but doesn’t lead to a proper VSA selection. Once the VM is not running on the same host as a VSA, any VSA is assigned.
Are there any further settings to enable (or the other way arround to disabled) that lead to a propper asignment of VMs to VSA ?
As a workaround, I now assigned the usable/wanted VSA now to each virtualization client’s subclient instead of the instance only. This restricts the VSA to the local fault domain only, but this is another option to think of, when creating new subclients for VM backups …
