Virtual Recovery Assistant: Protecting a Server with a Hyper-V Virtual MachineDouble-Take can be used to protect entire physical or virtual machines with Microsoft Hyper-V virtual machines. Double-Take uses Virtual Recovery Assistant technology to automatically provision the virtual machines for you on the target Hyper-V host, greatly simplifying the protection process. The Double-Take clients are used to create protection jobs. The target Hyper-V host server is a physical machine that the Hyper-V host software runs on.

All replica virtual machines will reside on this host. Virtual replica machines are hosted by the Hyper-V host server. The virtual replica machines

are created by the source protection job, but remain powered off until failover. At failover, the replica machine is powered on and assumes the identity of the original source machine.

Failing over to the replica virtual machineDouble-Take Console provides the ability to failover to a replica virtual machine in the event of a failure of the source machine. Source servers may be failed over in two different ways: Automatic FailoverThe application detects that a failover condition is met and automatically

initiates the failover process. Manual FailoverThe user manually initiates the failover process by clicking the Failover

button in the user interface.The type of failover for the job is selected during job creation. For more information, see Setting protection options on page 4-9.After the protection job completes the initial synchronization, failover will be enabled. To initiate failover, select the connection and click the Failover button on toolbar at the bottom of the Monitor Connections page.During the failover process, the following steps are initiated by Double-Take Console:1. The Double-Take connection between the source machine and target Hyper-V host is

disconnected. 2. If you are performing manual failover and the source can be contacted, the source machine is

shut down.3. The target virtual disk volumes are connected to the replica virtual machine.4. The replica virtual machine is powered on.Because of the nature of physical-to-virtual failover process, failback to the original source is not possible.

Reusing virtual hard disksVirtual hard disks (VHDs) created by a virtual recovery protection job can be re-used by Double-Take Console. This can be useful for pre-staging data on the target over a LAN connection, and then moving your target Hyper-V server to your remote disaster recovery site after the initial synchronization. When you re-use an existing VHD file, Double-Take Console performs a difference mirror instead of a full mirror. To reuse a VHD:1. Create a protection job over the LAN connection.2. Allow the job to complete the initial synchronization.3. Delete the protection job. When prompted, choose the option to Keep and register the replica

virtual machine.4. From the Hyper-V manager, delete the replica virtual machine. Doing this will delete the virtual

machine configuration but will keep the associated VHD files.5. Shut down and move the Hyper-V target server to your remote disaster recovery site.6. After the target server is online, create a new protection job for the same source server used in

the original job.7. During job creation, when you select the replica path, if a VHD file with the same name exists,

Double-Take Console will display a prompt asking if you would like to re-use the existing VHD. Select Yes.

8. Double-Take Console will re-use the existing VHD files and perform a file difference mirror over the LAN.4 - 11

Double-Take for Hyper-V:Protecting a Hyper-V Virtual MachineWith Double-Take Console for Hyper-V, you can use the Double-Take Console to protect virtual machines running on the Microsoft Hyper-V platform. Double-Take Console replicates all of the files associated with the virtual machine for one Microsoft Hyper-V host to another. Double-Take for Hyper-V can be used to: Automate the discovery and protection of virtual machines. Map the source virtual switches for a virtual machine to the available virtual switches on the target

Hyper-V host. Monitor IP addresses and perform a manual failover when a failover condition is met. Bring the replica virtual machine online with the network adapters disabled, allowing you to test

the replica virtual machine while the source is still online.

Supported configurationsYour Double-Take for Hyper-V environment must conform to the following requirements. The source virtual machine be in its own home folder that is not shared by any other virtual

machines. The source virtual machine cannot be created in the Hyper-V system default folder. The source virtual machine cannot be replicated into to Hyper-V system default folder on the

target host. The replica virtual machine folder on the target must be unique to the replica virtual machine. The source virtual machine snapshot folder must be unique to the virtual machine, and it cannot

be in the Hyper-V system default folder. The replica virtual machine snapshot folder cannot be the Hyper-V system default folder. The replica virtual machine cannot share a snapshot folder with any other virtual machines. After protection has been configured for a virtual machine, the location of the snapshot folder for

that virtual machine cannot be changed. If the snapshot folder is changed, the protection job must be removed and re-created.

If a protected virtual machine is renamed in the Hyper-V manager, the replica virtual machine will not be renamed. In order to pick up the name change, the protection job must be removed and re-created.

Virtual machines cannot use raw, pass-through, or differencing disks. Clustered Hyper-V source and target environments are not supported.Double-Take for Hyper-V supports the following host protection configurations when protecting Hyper-V virtual machines: Many to OneVirtual machines from multiple Hyper-V hosts can be protected on a single

Hyper-V target host. One to OneVirtual machines from a single Hyper-V host can be protected on a single Hyper-V

target host. Many to ManyThe Double-Take Console can manage multiple Hyper-V source and target hosts,

allowing you to protect virtual machines from multiple Hyper-V hosts on multiple Hyper-V targets. 5 - 1

The following host protection configuration is not supported by Double-Take for Hyper-V. Chained configurationsDouble-Take for Hyper-V will does not support protecting virtual

machines to a target Hyper-V host, and then in turn protecting those virtual machines from the first target host to an additional target Hyper-V host.

Virtual hard disksDouble-Take for Hyper-V monitors the virtual disks of a protected virtual machine for changes to the disk layout. If a virtual hard disk (VHD) is added to the virtual machine, Double-Take for Hyper-V will update the protection job to include the new VHD. This will start a file difference mirror.If a VHD is removed from a protected VM, Double-Take for Hyper-V will correctly update the configuration of the replica VM to include the new disk layout. However, the VHD will not be removed from the protection job until it is deleted from the source machine, or the job is removed and re-created.

Performing failoverAfter the protection job completes the initial synchronization, failover will be enabled. To initiate failover, select the connection and click the Failover button on the Monitor Connections page. When you select the Failover button, the following dialog box appears.

From here, you can select the type of failover to perform. Live failoverSelect this option to perform a live failover with network connectivity to the target

replica virtual machine. Live failover will shut down the source virtual machine (if available), stop the protection job, and start the replica virtual machine with full network connectivity.

Test failoverSelect this option to perform a test failover without network connectivity to the target replica virtual machine. Test failover will leave the source virtual machine online, suspend the protection job, and start the replica virtual machine on the target with no network connectivity. This feature allows you to periodically test the replica virtual machine to verify that it is working correctly.

After you select the type of failover to perform, click Failover.

Undoing failoverOnce a live or test failover has been performed, it is possible to undo the failover by clicking on the Undo Failover button. Undoing failover will do the following:1. The replica virtual machine will be shut down2. The source virtual machine will be restarted (if it was shutdown with a live failover)3. The protection will be restarted (a file difference mirror will be performed)

NOTE: All changes made to the replica virtual machine while the job is in a failed over state will be lost when an Undo is performed.5 - 9

Reversing failoverAfter a live failover has been performed, you can reverse the protection. This allows you to replicate target data back to the source. Select a protection that has already failed over, then click the Reverse protection button to start the protection in the reverse direction.The job will start synchronization in the reverse direction. The job name and the log file name will change accordingly. When the restore completes, the job will be running in the opposite direction (that is, if the job had originally been running from server Indy to server Jersey, it will now be running from server Jersey to server Indy).After the job completes synchronization back to the original source host, failback can be performed by clicking the Failover button.5 - 10

Using FirewallsIf your source and target are on opposite sides of a NAT or firewall, you will need to configure your hardware to accommodate Double-Take communications. You must have the hardware already in place and know how to configure the hardware ports. If you do not, see the reference manual for your hardware.In a NAT or firewall environment, you must have a static mapping where a single, internal IP address is always mapped in a one-to-one correlation to a single, external IP address. Double-Take cannot handle dynamic mappings where a single, internal IP address can be mapped to any one of a group of external IP addresses managed by the router.

Double-Take portsYou will need to verify that the following ports are open for Double-Take communications:

Double-Take uses ICMP pings to monitor the source for failover. A failover monitor will not be created if ICMP is blocked (although the data and system state will still be protected). You should configure your hardware to allow ICMP pings between the source and target. If you cannot, you will have to monitor for a failure manually and create a dummy monitor at failover time that can be manually failed over. Contact technical support for assistance with this manual process.

Microsoft Windows portsDouble-Take uses WMI (Windows Management Instrumentation) which uses RPC (Remote Procedure Call). By default, RPC will use ports at random above 1024, and these ports must be open on your firewall. RPC ports can be configured to a specific range by specific registry changes and a reboot. See the Microsoft Knowledge Base article 154596 for instructions. Double-Take also relies on other Microsoft Windows ports.

Microsoft File Share uses ports 135 through 139 for TCP and UDP communications. Microsoft Directory uses port 445 for TCP and UDP communications. These ports must be open on your firewall. Check your Microsoft documentation if you need to modify these ports.

Hardware portsYou need to configure your hardware so that the Double-Take and Microsoft Windows ports are open. Since communication occurs bidirectionally, make sure you configure both incoming and outgoing traffic. There are many types of hardware on the market, and each can be configured differently. See your hardware reference manual for instructions on setting up your particular router.
