Configuring backups:

Hyper-V Recovery:

1. Turning the VM offline for recovery:

· Once the VM is offline, the recovery process destroys the current VM, recovers the recovery ve rs ion, and registers the VM.

· The Hyper-V Writer automatically detects whether the VM i s online, and turns it off. No action is required by you.

2. Hosting the recovered virtual systems:

· The Destination Host page allows you to specif y the server on which you want to host the recovered virtual systems.

3. Specifying the destinations for the Hyper-V configuration files and virtual system:

· The Destination Path page allows you to specify the destination directory for the Hyper-V configuration files, and the destination host for each virtual system.

4. Selecting Hyper-V recovery options

5. Selecting the destination of Hyper-V recovery:

· To the original machine

· To a different machine or location

· When you perform a Hyper-V recovery on Windows Server Core 2008, 2008 R2, 2012, or 2012 R2 the recovery is a directed recovery. Because the Server Core installation does not provide a GUI

6. Recovering Hyper-V CSV VMs

CSV VMs Overview

NMM supports recoveries for Hyper-V CSV VMs at the cluster level and at the individual CSV VM level. NMM supports recoveries only on supported NMM hosts that run the Hyper-V service. This host may be outside of the cluster.

NMM recovers the CSV VMs that you select on the cluster node where the VM is currently active. If a CSV VM does not exist at the time of recovery, then NMM recovers the VM to the majority node.If no VMs exist in the cluster, then for the deleted VM:

· If the winclient started within the cluster, then the recovery operation starts on the node that runs the winclient.

· If the winclient is started from outside cluster, then NMM recovers the deleted VM to the cluster owner node.

Relocation recovery of a clustered VM to a node where it is not active is not allowed on the cluster where the VM resides. If you request a relocated recovery of a VM to a node on a cluster, but the VM is already active on another cluster node, then the recovery will fail.

EMC recommends that you move the VM to the desired node first and then initiate the VM recovery. When you select a single VM in the Hyper-V Plug -in, NMM supports the following types of recoveries:

· Default recovery:

(Recover on the cluster node where the VM is active) — This is the default recovery when you click “Recover…” NMM recovers the selected VM to the cluster node where it is active. If the VM does not exist, NMM recovers it to the majority node where most of the VMs are active.

· Advanced recover:

When you click the “Advanced Recover…” option, you can select one of the following options:

• Recover Virtual System to active virtual system cluster node If the VM is already active on the destination cluster node, then you can recover the VM t o a path that differs from the path at the time of the backup.

• Recover Virtual System to a different cluster node

You can recover the selected VM to an alternate node in the cluster if the VM does not exist in the cluster. If the VM exists in the cluster but is not active on the destination node, then the recovery fails. In this case, first migrate the VM to the destination node and then perform either a default recovery or an advanced recovery.
