Testlet: Northwind Traders
You need to recommend a backup strategy for Hyper-V.
What should you recommend?
Case Study Title (Case Study):
COMPANY OVERVIEW
Northwind Traders is an import/export company that has a main office and two branch offices. The main office is located in Toronto. The branch offices are located in Vancouver and Seattle. The main office has 2,000 users. Each branch office has 500 users.
EXISTING ENVIRONMENT
All client computers run Windows 7 Enterprise. All servers run Windows Server 2008 R2. All new servers are deployed by using Windows Deployment Services (WDS).
Northwind Traders has multiple Hyper-V servers. The Hyper-V servers are managed by using Microsoft System Center Virtual Machine Manager (VMM).
The perimeter network contains a standalone server. The server has the Active Directory Lightweight Directory Service (AD LDS) service role installed. AD LDS is administered on the server by using the Active Directory module for Windows PowerShell.
All virtual machines (VMs) access iSCSI-based storage by using a Microsoft iSCSI Initiator installed on the VM.
Existing Active Directory/Directory Services
The network contains a single Active Directory forest named northwindtraders.com.
The forest contains five Remote Desktop servers. All Remote Desktop servers are in an organizational unit (OU) named RD Servers.
TECHNICAL REQUIREMENTS
Northwind Traders must meet the following technical requirements:
. Minimize server downtime.
. Ensure that you can recover all of the data hosted on the VMs.
. Ensure that you can perform bare metal restores of the Hyper-V servers.
. Minimize the number of times a server restarts when it is deployed.
. Monitor the CPU utilization, memory utilization, and disk utilization of all the servers to analyze performance trends.
. Ensure that a specific set of Group Policy settings are applied to users who use Remote Desktop to connect to the Remote Desktop servers. The settings must differ from those applied when the users log on locally to their own computers.
. Copy a custom Microsoft Office Word dictionary to the computers in the legal department. Update the custom dictionary on a regular basis. Copy the updated version of the dictionary as soon as possible to the legal department computers.
A. Take a snapshot of each VM, and then run a full backup of the Hyper-V hosts by using Windows Server Backup.
B. Shut down the VMs, and then run a full backup of the Hyper-V hosts by using Windows Server Backup. Restart the VMs when the backup is complete.
C. From each VM, run a full backup by using Windows Server Backup, and then run a full backup of the Hyper-V hosts by using Windows Server Backup.
D. From each VM, run a full backup by using Windows Server Backup. Shut down the VMs, and then run a full backup of the Hyper-V hosts by using Windows
Server Backup. Restart the VMs when the backup is complete.
Correct Answer: C

HYPER-V BACKUP
The backup integration service (identifiable as Hyper-V Volume Shadow Copy Requestor service in the guest operating system) and the Hyper-V Volume Shadow Copy Service (VSS) writer provide the mechanism for backing up virtual machines as well as system-wide settings that apply to Hyper-V. To implement the backup and recovery scenarios discussed in this section, you must use a backup application that is compatible with the Hyper-V VSS writer. If you want to use Windows Server Backup, you must add a registry key to register the Hyper-V VSS writer.
There are two basic methods you can use to perform a backup:
. Perform a backup from the server running Hyper-V. We recommend that you use this method to perform a full server backup because it captures more data than the other method. If the backup application is compatible with Hyper-V and the Hyper-V VSS writer, you can perform a full server backup that helps protect all of the data required to fully restore the server, except the virtual networks. The data included in such a backup includes the configuration of virtual machines, snapshots associated with the virtual machines, and virtual hard disks used by the virtual machines. As a result, using this method can make it easier to recover the server if you need to, because you do not have to recreate virtual machines or reinstall Hyper-V. However, virtual networks are not included in a full server backup. You will need to reconfigure the virtual networking by recreating the virtual networks and then reattaching the virtual network adapters in each virtual machine to the appropriate virtual network. As part of your backup planning, make sure you document the configuration and all relevant settings of your virtual network if you want to be able to recreate it.
. Perform a backup from within the guest operating system of a virtual machine. Use this method when you need to back up data from storage that is not supported by the Hyper-V VSS writer. When you use this method, you run a backup application from the guest operating system of the virtual machine. If you need to use this method, you should use it in addition to a full server backup and not as an alternative to a full server backup. Perform a backup from within the guest operating system before you perform a full backup of the server running Hyper-V.
You can perform an online backup with no downtime on a running virtual machine when all of the following conditions are met:
. Integration services are installed and the backup integration service has not been disabled.
. ll disks being used by the virtual machine are configured within the guest operating system as NTFS-formatted basic disks. Virtual machines that use storage on which the physical partitions have been formatted as dynamic disks or the FAT32 file system prevent an online backup from being performed. This is not the same as dynamically expanding virtual hard disks, which are fully supported by backup and restore operations.
. Volume Shadow Copy Service must be enabled on all volumes used by the virtual machine with a specific configuration. Each volume must also serve as the storage location for shadow copies of the volume. For example, the shadow copy storage for volume C: must be located on C:.
If an online backup cannot be performed, then an offline backup is taken. This type of backup results in some degree of downtime. A variety of factors can affect the time required to take an offline backup. If the virtual machine is running or paused, it is put into a saved state as part of the offline backup process. After the backup is completed, the virtual machine is returned to its existing state.
