NAKIVO Backup & Replication v7.1: Hyper-V Failover Cluster Support
NAKIVO Backup & Replication v7.1 is released! The new version adds support for Hyper-V Failover Cluster. This means that you can add Hyper-V failover clusters to the inventory, add failover clusters to backup and replication jobs, and also let the product track VMs that jump between cluster nodes. But before we get more into this, let’s recap what Hyper-V Failover Clusters are and why you’d want to use them.
What is Hyper-V Failover Cluster?
A Hyper-V failover cluster is a group of Hyper-V servers connected with cables and with the software - Failover Cluster Manager. Each server in the cluster is called a “node” and you can configure the cluster in a way that if one of the nodes fails, the others start providing services. This process is called “failover” hence the name “failover cluster”.
The other great benefit that clusters provide is load balancing, which is achieved with the Performance and Resource Optimization (PRO) feature available in System Center Virtual Machine Manager. Microsoft PRO determines the load thresholds for each host separately and moves VMs if a specific cluster node becomes overloaded.
Hyper-V Failover Clusters Support in NAKIVO Backup & Replication
In NAKIVO Backup & Replication starting from v7.1, you can add Hyper-V Failover Cluster to backup and replication jobs, so all your important VMs are always protected. NAKIVO Backup & Replication automatically tracks changes inside the cluster, so if you add or remove a VM from the cluster, the product will automatically update the backup or replication job to reflect the changes.
The same is for moving VMs inside the cluster. When you move a VM inside the cluster, NAKIVO Backup & Replication detects the change automatically regardless of if the VM was moved manually or automatically.
The process of adding a failover cluster to NAKIVO Backup & Replication’s inventory is almost the same as adding a single Hyper-V host; you just need to specify that you add a cluster.
To add a failover cluster to the Inventory, you just need to specify an IP-address or a hostname of any cluster node.
After you add the failover cluster to the NAKIVO Backup & Replication’s inventory, you can add the cluster to a backup or replication job. What’s also great is that you can select an entire cluster and exclude VMs that you do not want to protect:
Happy clustering with NAKIVO Backup & Replication v7.1!
