Arcserve UDP Agent (Windows) in a Microsoft Hyper-V Environment

Arcserve UDP Agent (Windows) provides both host-level and virtual machine (VM) level protection for Microsoft Hyper-V environments. The following scenarios describe situations that you can encounter and offer protection solutions using Arcserve UDP Agent (Windows).

Note: Verify that you apply the appropriate license for each of these scenarios.

Scenario 1 - You want to protect your Hyper-V host server:

1. Install Arcserve UDP Agent (Windows) on the Hyper-V Host server.
2. Verify that you back up the system and boot volume (if you are choosing volume filtering).
3. If the Hyper-V host server goes down, follow the standard Bare Metal Recovery procedure in Arcserve UDP Agent (Windows) to recover your Hyper-V host server.
4. If you want to restore selected files, use the standard Arcserve UDP Agent (Windows) restore procedure.

Scenario 2 - You want to protect your Hyper-V host server and the Virtual Machines which are hosted on that server:

1. Install Arcserve UDP Agent (Windows) on the Hyper-V host server.
2. Verify that you back up the entire machine to provide complete protection of both the host server and VMs.
3. Submit the backup jobs.
4. To restore a VM from an Arcserve UDP Agent (Windows) backup, there are two possible solutions:
   1. Restore the VM to original location:
      • From the restore window in Arcserve UDP Agent (Windows), select the VM files (.vhd, .avhd, configuration files, and so on).
      • Select Restore to original location as the destination and select the Overwrite existing files option for resolving conflicts.
      • Submit the restore job.

      Note: The recommendation is to turn off the VM before submitting the restore job because if the older file is active, it will be overwritten by Arcserve UDP Agent (Windows) only after you reboot the Hyper-V host server to complete the restore process.

      • When the restore job has finished, open the Hyper-V Manager and start the VM.
      • If the VM is not yet registered in the Hyper-V Manager, create a VM. During the VM creation process, point the path of VM’s configuration and .vhd file to the same path of destination location where the restore was performed.
   2. Restore the VM to alternate location on the same Hyper-V Host server:
      • From the restore window in Arcserve UDP Agent (Windows), select the VM files (.vhd, .avhd, configuration files, and so on).
      • Select Restore to alternate location as the destination and provide a destination path.
      • Submit the restore job.
      • Open the Hyper-V Manager and create a VM when the restore job has finished. During VM creation process, point the path of VM’s configuration and vhd file to the same path of destination location where the restore was performed.
      • Start the VM, when the VM is created.

      Note: For more detailed information about restoring Hyper-V Virtual Machines, see the Microsoft Hyper-V documentation.

Scenario 3 - You want to protect your Hyper-V Virtual Machines:

To protect your Hyper-V Virtual Machines (VM) using Arcserve UDP Agent (Windows), there are two possible solutions:

1. Install Arcserve UDP Agent (Windows) on the Hyper-V host server
   • Using the Arcserve UDP Agent (Windows) Backup Settings, select the volume where the VM files (.vhd, .avhd, configuration files, and so on) are located.
   • Submit a backup job.
   • To restore a Hyper-V Virtual Machine from an Arcserve UDP Agent (Windows) backup, follow the steps for either of the restore solutions provided in Scenario 2.
2. Install Arcserve UDP Agent (Windows) inside the Windows Virtual Machine

   Follow the standard backup and restore procedure to protect the VM, the same as a physical machine.

Note: For scenarios 2 and 3a, if you attached/mounted an iSCSI LUN directly inside the VM, the data inside the LUN is not backed up using Arcserve UDP Agent (Windows) Hyper-V host level backups. You can overcome this limitation by using the same approach as the Install Arcserve UDP Agent (Windows) inside the Windows Virtual Machine solution in scenario 3b.
