How to protect Azure Stack Hub and Azure Stack HCI

Level 3

There are a lot of misunderstandings about Azure Stack solutions and how to protect each one of them.  I want to help you better understand each solution within Azure Stack portfolio and how to protect them using Veritas NetBackup.

As you already know, Veritas NetBackup is an enterprise-class backup and recovery suite that provides unified data protection for multi-cloud, virtual and physical environments that can be globally managed from a single console, including all Azure Stack solutions.

The usual misunderstanding is to think Azure Stack is a solution itself, but Azure Stack is a portfolio of products comprised of three distinct offerings – Azure Stack Edge, Azure Stack Hub, and Azure Stack HCI.  Azure Stack solutions help you extend Azure services and capabilities to your environment of choice – from the data center to edge locations and remote offices.

The confusion kicks in mostly between Azure Stack Hub and Azure Stack HCI and how to protect them.


The most important feature of HCI is that it can run “disconnected” from Azure, in other words, HCI is just like your branch office server.  It is a box that contains compute, power, storage, and network connections and holds Hyper-V based virtualized workloads and it has the option to connect to some Azure services.

And so, as it is like a Hyper-V server, you can use Veritas NetBackup Hyper-V policy type to protect it along with all the features Veritas NetBackup already provided for Hyper-V:

  • NetBackup for Hyper-V uses snapshot technology to keep virtual machines 100% available to users. NetBackup for Hyper-V creates quiesced Windows snapshots using Volume Shadow Copy Service (VSS) and Windows Management Instrumentation (WMI).
  • NetBackup for Hyper-V performs full backups and file-level incremental backups of the virtual machine. With the WMI backup method, it also performs block-level incremental backups and Accelerator backups.
  • Can restore the full virtual machine from the following:
    • Full backups of the VM.
    • Block-level incremental backups of the VM.
    • Accelerator backups of the VM.
  • Can restore individual files of the virtual machine from the following:
    • Full backups of the VM.
    • File-level incremental backups of the VM.
    • Block-level incremental backups of the VM.
    • Accelerator backups of the VM.
  • Can restore to the original virtual machine, to other locations on the Hyper-V server, or to a different Hyper-V server.

On the other hand, Azure Stack Hub is really the on-premise extension of the Azure public cloud.  Almost everything you can do in the public cloud, you could also deploy on Hub: from VMs to apps, all managed through the Azure portal or even Powershell, including things like configuring fault and updated domains.

In this case, you can still use the same deployment of Veritas NetBackup to protect your in-cloud workloads.  The cloud data protection framework leverages the CloudPoint infrastructure to drive faster proliferation of cloud providers, since v8.3, CloudPoint can protect assets in AWS, AWS Outpost, Azure, Azure Stack hub and GCP clouds.  Features includes:

  • Automatic discovery of cloud assets:  NetBackup retrieves the cloud assets pertaining to the cloud accounts every 2 hours by default.  This period is configurable.
  • Protection of intelligent cloud groups based on a set of filters called queries.  All the assets satisfying the query conditions will automatically be protected.
  • Protection of Microsoft Azure resources using resource groups.
  • NetBackup Accelerator backups.
  • Application consistent snapshots.  You can perform original location and alternate location restores.
  • Incremental snapshots.
  • Backup from snapshot.
  • Restore from snapshot copy, replica copy, backup copy or duplicate copy.
  • Restore VMs to an alternate configuration, to a different region, to a different subscription, and restore VMs or disks to a different resource group.
  • Granular files and folders restore
