Azure Stack HCI: Backing up and Restoring VMs

Jude Daniel, Sr. Product Manager

As more and more businesses are moving towards the cloud, the need for robust backup and disaster recovery solutions is becoming increasingly important. At Druva, we understand the challenges faced by IT teams when it comes to data protection, especially in hybrid cloud environments. That's why we are excited to announce our support for the backup and restore of virtual machines (VMs) in Azure Stack HCI.

Azure Stack HCI is a hyper-converged infrastructure (HCI) solution that combines compute, storage, and networking into a single system. It allows businesses to run virtualized workloads on-premises, while also providing seamless integration with Azure services. With Druva's support for the backup and restore of VMs in Azure Stack HCI, businesses can now ensure the availability and recoverability of their critical data in the event of a disaster.

Here are some of the key features of our backup and restore solution for Azure Stack HCI:

Agentless Backup

Our solution is agentless, which means that you don't need to install any agents on your VMs. This simplifies the backup process and reduces the risk of errors.

Application Consistent Backups

We ensure application-consistent backups of your VMs, which means that we take into account the state of the applications running on the VMs when we perform backups. This ensures that your data is recoverable to a point in time where the applications were in a consistent state.

Forever Incremental Backups

Druva performs incremental backups, which means that we only back up changes made to the VMs since the last backup. This reduces the backup window and minimizes the impact on your production environment.

Granular Restore

Our solution provides granular restore options, which means that you can restore individual files, folders, vhdx disks or entire VMs. This gives you the flexibility to restore only what you need and reduces the recovery time.


Druva utilizes client-side, global deduplication, which means that we can identify and eliminate duplicate data across all backups. This reduces the amount of data that needs to be stored, which in turn reduces the storage costs. 


We understand the importance of securing your data, especially in hybrid cloud environments. Our solution encrypts data both in transit and at rest, using industry-standard AES-256 encryption. 


Druva architecture is fundamentally designed to support various workloads whether they reside in Cloud or On-Premise environments.

In conclusion, our backup and restore solution for VMs in Azure Stack HCI offers several technical features that provide businesses with a comprehensive and efficient data protection solution. Our solution ensures application-consistent backups using Resilient Change Tracking (RCT) and Volume Shadow Copy Service (VSS) and supports block-level backups, which reduces backup time and storage requirements.

We understand the importance of securing your data, and our solution encrypts data both in transit and at rest, using industry-standard AES-256 encryption. Our solution also provides flexibility for businesses with a hybrid cloud environment by supporting restore to Hyper-V environments, allowing businesses to restore their VMs to a different platform depending on their needs.

Overall, our backup and restore solution for VMs in Azure Stack HCI is designed to provide businesses with a reliable, efficient, and secure data protection solution that meets their evolving needs. We are committed to providing our customers with the best possible backup and restore solution and will continue to innovate and improve our solution based on their feedback and needs.
