Windows Server 2019 Cluster Set Consideration

Cluster sets is the new cloud scale-out technology in the Windows Server 2019. This technology increases the cluster node count in a single Software-defined Data Center (SDDC) cloud by orders of magnitude. A cluster set is a loosely coupled grouping of multiple Failover Clusters: compute, storage or hyper-converged. The Cluster sets technology enables virtual machine fluidity across member clusters within a cluster set and a unified storage namespace across the set, in support of virtual machine fluidity.

You can protect virtual machines using Arcserve Host-Based Agentless backup.

Key Considerations:

• Use any of the cluster node as the Agentless backup proxy. If cluster member is not used as the Agentless backup proxy, the backup job fails as the unified storage namespace (Cluster Set Namespace) referral Scale-Out File Server (SOFS) is not accessible from other servers.
• Install File Server VSS Agent Service on the Management cluster nodes and Member cluster nodes.
• After a virtual machine is migrated to another cluster, you will need to import it from new cluster and add to plan accordingly.
• For one virtual machine, in each cluster, the first backup job is converted to full and subsequent jobs are incremental.
• Arcserve UDP does not register a virtual machine to cluster set during a recovery job, register the virtual machine manually as needed.
• After a live migration, the next backup job in new cluster kept as incremental, while for other MoveType the job will be converted to verify.
