Location of the restored virtual machine in a cluster
This topic pertains to NetBackup for Hyper-V.
When you restore a virtual machine to a cluster, you can restore to the original location or to a different location. But for a virtual machine that failed over to another node after the backup occurred, what is the original location? Is it the node (Hyper-V server) where the virtual machine resided when it was backed up, or the node where it now resides?
The following table is a decision chart for restore to original location in a cluster. It indicates where the virtual machine is restored. The location depends on the virtual machine's high availability (HA) state when it was backed up and when it was restored.
Table: Decision chart for restore to original location in a cluster
Is the virtual machine status HA at time of backup? | Is the virtual machine status HA at time of restore? | Virtual machine is restored to this node (to non-HA state): |
|---|---|---|
Yes | Yes | The restore behavior depends on the backup method that was used to make the backup (WMI or VSS):
|
Yes | No | For both WMI and VSS: Restored to node on which the virtual machine resided at the time of backup. |
Yes | Virtual machine does not exist. | For both WMI and VSS: Restored to node on which the virtual machine resided at the time of backup. |
No | Yes | For both WMI and VSS: Restored to node on which the virtual machine resided at the time of backup. At the time of restore, if virtual machine resides on a different node than where it resided when backed up, the restore fails. |
No | No | For both WMI and VSS: Restored to node on which the virtual machine resided at the time of backup. |
No | Virtual machine does not exist. | For both WMI and VSS: Restored to node on which the virtual machine resided at the time of backup. |
Note:
In all cases, the virtual machine is restored to the non-HA state.
