Abstract

This article describes how Cloud Backup for Virtual Machines can be used to backup and restore Azure VMware Solution virtual machines on Azure NetApp Files datastores. Cloud Backup for Virtual Machines takes VM-consistent backups which leverage native Azure NetApp Files snapshot technology resulting in fast, space-efficient restore points that help you meet your recovery point objectives and reduce total cost of ownership.

 

Cloud Backup for Virtual Machines integrates natively into the Azure VMware Solution vSphere client making backup and restore operations quick and easy, resulting in decreased recovery time objectives.

Introduction

Azure NetApp Files (ANF) is a high-performance, Azure-native file storage service for the most demanding enterprise file workloads. Azure VMware Solution (AVS) supports attaching NFS datastores as a persistent storage option. By using NFS datastores backed by Azure NetApp Files, you can expand your storage without adding AVS nodes when additional compute and memory may not be needed.

 

Cloud Backup for Virtual Machines is a Microsoft supported backup and recovery solution for virtual machines on Azure NetApp Files datastores for Azure VMware Solution. Cloud Backup for Virtual Machines provides VM-consistent or crash consistent backups of VMs, groups of VMs or complete datastores. Backups can be scheduled or created on-demand, and virtual machines (VMs) and VMDKs can be restored from a backup directly from the vSphere client.

 

 

 

Scenario

This article covers the following:

  • Simplified deployment and management:
    Cloud Backup for Virtual Machines can be installed directly from the Azure portal.

  • Policy-based backup management:
    Creating backup policies is simple and done right from the vSphere client.

  • Restoring a virtual machine or VMDK:
    Complete virtual machines or VMDKs are restored quickly and easily.

  • Management capabilities:
    Built-in dashboards provide at-a-glance summaries of backup and restore status.

 

Simplified deployment and management

Cloud Backup for Virtual Machines is a plug-in installed in the Azure VMware Solution private cloud from the Azure portal. Installation is automated via the Azure VMware Solution ‘run command’. This automated deployment simplifies the setup experience by doing away with the requirement to import packages or setup files from an external site. Maintenance and upgrades of the Cloud Backup for VMs plug-in are also completed via the ‘run command’ experience.

 

 

Cloud Backup for Virtual Machines is integrated with vCenter and automatically displayed in the VMware vSphere client providing a seamless experience.

 

 

The Getting Started wizard in the Cloud Backup for Virtual Machines user interface (UI) walks you through adding your cloud subscription credentials to securely connect to the Azure API.

Policy-based backup management

A resource group is the container for VMs and datastores that you want to protect. A resource group can contain an entire datastore, a single VM or multiple VMs. To optimize snapshot copies, group VMs and datastores stored in an Azure NetApp Files volume into one resource group.

 

 

Cloud Backup for Virtual Machines uses backup policies to perform on-demand or scheduled backups for a resource group.  Backup policies can be configured to retain backups with a specified retention count, automatically deleting backups that exceed the retention count. The frequency setting within a policy specifies a backup frequency of Hourly/Daily/Weekly/Monthly or on-demand only.

 

A backup policy allows you to create crash consistent and VM-consistent snapshot backups. VM-consistent snapshot backups pause the VMs and create a VMware snapshot each time the backup job runs. Cloud Backup for Virtual Machines then performs its backup operation, and then VM operations are resumed.

 

 

A backup schedule must be configured for each policy. Cloud Backup for Virtual Machines creates schedules in the time zone in which the Cloud Backup for Virtual Machines is deployed.

 

 

Cloud Backup for Virtual Machines can perform an on-demand backup or create a VM consistent or crash consistent backup as per the defined backup schedule.

Restoring a virtual machine or VMDK from backup

Cloud Backup for Virtual Machines can perform a restore of an entire virtual machine or individual virtual machine disks (VMDK) from a backup.

Management capabilities

Cloud Backup for Virtual Machines ships with a dashboard that provides an overview of job activities, summary of protected resources, job and log management and reporting capabilities.

 

 

Summary

Cloud Backup for Virtual Machines provides simple, seamless protection for Azure VMware Solution virtual machines on Azure NetApp Files datastores. Policy based, automated and consistent backup of VMs. Azure NetApp Files snapshot technology provides fast and efficient backups of individual VMs, groups of VMs (organized in resource groups) or complete datastores. Restores of entire virtual machines (VMs) or individual VMDKs can be managed through the vSphere client.

  • Hi,

    1. Is it accurate to assume that in the event we lose the NFS volume, we would lose all the backups too because they are essentially snapshots within the volume? 
      Are there plans to have an offsite replication outside of the volume to protect against cyber-attacks / malicious activity on the volume?

      Today, Cloud Backup for Virtual Machines uses native Azure NetApp Files snapshots to create restore points. Yes, as these snapshots are part of the volume, for near-instantaneous recovery purposes, if you were to lose the volume, these snapshots would be lost as well. Besides snapshots you'd need a backup on different location/media. Today, you can use cross-region or cross-zone replication to replicate these volumes to another region or zone. Doing so would give you the ability to recover your data should something catastrophic happen to the primary/source volume. Alternatively you can consider using AzCopy to take backups to Azure storage account from the volume's .snapshot directory.

    2. Is there an additional cost to enabling these CB for AVS VM?

      There is no additional cost to use Cloud Backup for Virtual Machines.

    3. During the demo, we selected an ANF datastore but you stated we could select a vSAN datastore too - We would like to use one way to protect all our VMs in AVS - ones running on ANF and on vSAN too, can we use CB for VMs for both type of datastore VMs? if yes, where would those backups land (in a separate RG/Volume?)

      We' ll review the video to confirm that statement. Can you indicate in which video at what timestamp that comment was made?

      Regardless, Cloud Backup for Virtual Machines can only be used to backup Azure NetApp Files datastores and virtual machines stored on Azure NetApp Files datastores.
