Data Backup and Recovery
Can anyone shed a light to the following questions.
SMHV 2.1, Windows 2012 R2 Hyper-V cluster, two nodes.
Two CSV volumes: one for VMs, another for Snapinfo.
I enabled distributed [application consistent] backup in the backup policy settings.
There is only a few words about distributed backup in the SMHV guide:
The distributed application-consistent backup feature enables multiple VMs running on
the partner cluster nodes to be consistent in a single hardware Snapshot copy made from the backup
node. This feature is supported for all the VMs running on a CSV 2.0 Windows volume across
multiple nodes in a Windows Failover Cluster. To use this feature, select the Applicationconsistent
backup type and select the Enable Distributed Backup check box.
As I can see, SMHV created a scheduled backup job on each cluster node.
My question: How can I run a backup job manually ? Where it should be started ? Which node ?
We use post-backup script which saves $VMSnapshot in the text file.
Where post-backup script will be started if we use distributed backup ? On both nodes ?
Why Reports are located on only one node ? How should my script recognize, where is located the latest report ?
you can use the 'New-Backup' command let in order to launch a new backup manually or with a script.
You can also manually kick off a windows scheduled task manually or via a script.
The job should start from the cluster's quorum owner.
how to find it out: In Windows 2008, you open cmd and type "cluster group" and check who owns the cluster group.
Similarly, in Windows 2012, you open a powershell with administrative priviledges and type: "get-clustergroup" and check who owns the cluster group.
with scripts, you can extract the node name from the output and launch the script on that node.
hope that helps,
