Datrium 4.0 – Welcome to The Cloud DVX! BaaS, CloudView and RBA

Datrium announcements are often characterized by technology improvements as an evolution of the shipping platform. However, we are on a journey to deliver the best practical solutions that bridge the operational gaps between on-premise and public clouds, moving organizations to a world where the underlying nuts and bolts are not relevant to achieving the best business outcomes.

As part of this mission, we have already simplified on-premise infrastructure, collapsing and eliminating enterprise storage silos, and removing day-2 configuration complexity and maintenance requirements. Yes, Datrium DVX does not require application knowledge specificities that other converged and hyperconverged products demand from users and admins to enable/disable data services such as compression, dedupe, erasure coding and replication.

Check out Datrium 3.1 Features Overview (Beyond Marketing) where Datrium is crowned by IOmark as the most scalable, fastest and lower latency storage platform (converged or not) on the market.



Welcome The Cloud DVX!

The Cloud DVX is a zero-administration Software-as-a-Service piece of the overall Datrium platform solution that lives on the cloud (AWS). As a part of the service offering, Datrium manages the service availability, automated software upgrades as well as proactive support and self-healing functions related to Datrium and AWS resources.

The Cloud DVX is the brains for on-premise DVX instances. The software is built on the same split provisioning foundation as the on-premise DVX, enabling massive scalability of compute or capacity independently and on-demand. Furthermore, the same superpowers of (LFS) Log-Structured Filesystem is behind the Cloud DVX.

In this post, I highlight the three initial use-cases that are being delivered in the next few months or are part of a short-term product roadmap.



Cloud is the New Tape – Backup-as-a-Service

Traditionally IT organizations provide incremental and differential snapshots and backups of running systems and store an extra copy on an on-premise secondary storage for quick retrieval (low RTO), and later the same data is archived to tape for long-term retention.

Cloud DVX Backup-as-a-Service delivers native dedupe-aware backup and archival capabilities to the AWS cloud. Cloud DVX collapses the long-term archiving tier, traditionally owned by tape vendors, and enables organizations to go to the cloud with an extremely secure, cost-effective and remarkable RTO.

Cloud DVX BaaS offers a self-managed (CrashPlan like) solution that supports multi-site, multi-system, and multi-object end-to-end global deduplication with full data efficiency and encryption on the wire and at rest. Also, because the service supports end-to-end encryption, there is no need to add a separate VPN and related AWS charges.


Datrium Cloud Groups


Because the Cloud DVX provides direct-to-host restore, the management (and cost) of an additional on-premises backup or cloud gateway device is eliminated, further simplifying public cloud backup and recovery.

  • One-click setup with AWS
  • Multi-site, -system, -object global dedupe
  • Full data efficiency on wire, at-rest
  • Forever incremental native backups
  • VM and vDisk granular recovery
  • Built-in E2E encryption (no VPN charges)
  • Direct cloud-to-host restore
  • Global Catalogue
  • Automated Self-Healing
  • Automated Upgrades
  • Proactive Support


How does it work?

Under the covers, Cloud DVX deploy an EC2 instance and S3 tables using your AWS credentials. The EC2 instance performs WAN optimization, global deduplication and more.

Data is stored using AWS S3, and is priced by AWS based on capacity used and also on put and get operations, for both metadata and data. For this reason, being globally dedupe-aware and not sending or receiving the same data blocks twice is extremely important to maintain the cost-effectiveness of the solution. Datrium DVX can do that even when end-to-end encryption is in use.

Cloud DVX has been designed to do incrementals forever type of remote backups.  The only reason to send full backups is when new VMs have been created or during an initial seeding.  However, even in this case, global dedupe is employed to send just the missing pieces. The same logic applies when trying to recover data.  Only the missing pieces are sent back, making the experience faster and cheaper.

As we all know, AWS services sometimes can go down.  So, we use AWS Lambda to monitor the Cloud DVX services., continually looking for anomalies and issues, and self-healing the system.  Datrium’s Lambda monitoring software detects and rectifies the issue by restarting services using different resources, therefore masking AWS eventual issues. Finally, the admin can also select the desired AWS region to store snapshots, via Datrium GUI.

Check out right now the newly updated website with all info on Cloud Backup as a Service, and watch the video below demonstrating the AWS setup on Datrium taking only 60s. It’s that simple!

With v1.0, up to 30TB raw (global pre-dedupe) and 4 DVX systems are supported, but numbers will increase with upcoming releases.

CloudView – The Cloud is the System, One thing to Manage

The Cloud DVX is also the single GUI for on-premise, private and public DVX systems, offering one unique and straightforward cloud service for multiple sites, systems, or departments. The name of this service is CloudView.


CloudView collect data from DVX systems every few minutes to perform data analytics, correlation and root-cause analysis across all connected systems. Furthermore, based on the data CloudView will promote dynamic workloads, placing the right data at the right place. Additionally, CloudView will become the API gateway to communicate with multiple DVX deployments.


If you liked Nimble InfoSight, you’ll love CloudView.

Single File Restore – Power to the Users

Today organizations rely on numerous vendors to allow users to perform Single File Restore, as opposed to restoring the whole virtual disk (VMDK). Datrium SFR works in tandem with the Cloud DVX, enabling guest objects, such as word documents, to be seamlessly retrieved from any Datrium storage tier, including cloud, back to the user operating environment.

Using powerful analytics and a global catalog the Cloud DVX will enable advanced searches, but over time it will provide additional insights into app-specific requirements and recovery modes, such as for Exchange and SQL.

We will soon provide more information on how DVX Single File Restore works.

IR2 or Instant Remote ReStart – Orchestrated  Disaster Recovery

Many convergence and hyperconvergence vendors are trying to solve the hybrid cloud puzzle, but they are all focused on providing a single cloud and single hypervisor solution. We are not building a hypervisor. We are not building a custom cloud. We aim to deliver a feature-rich turn-key orchestration solution for the multi-hypervisor and multi-cloud world, be it VMware, RHEV, Azure, AWS, GCP, or VMware Cloud on AWS.

The Cloud DVX is the brains and the witness agent for the recovery orchestration engine, and provide the automation framework that is being used to restore Protection Groups (PG’s), VM’s, and Datastore Files in a systematic and repeatable way.

Datrium customers will be able to select VMs for protection, choose a pre-defined or create a new runbook automation (RBA) template, and the applications are then replicated in the background, ready to be recovered on AWS in the event of a site failure.


We will soon provide more information about IR2, but it encompasses DR Test and Reporting, Failover and Failback, Planned Migrations and Data Cloud Workload Mobility.


If you are familiar with VMware SRM (Site-Recovery-Manager), think of that for multi-DVX systems and multi-Cloud.


IR2 orchestration fundamental roadmap entails:

  • From on-prem to on-prem
  • From on-prem to cloud
  • From cloud back to on-prem

With v1.0, the focus is on orchestrating and automating the registration and power-on of VM’s and supporting changes to the VM’s (such as networking mappings) that are necessary to bring them up in the target environment. DR orchestration will be initially available between on-premise DVX systems across multiple sites, soon followed by AWS as a target.

(ETA) H2 2018


There is lots of goodness coming from the Cloud DVX, but there are also many more features and enhancements to the on-premise Datrium DVX software that will be available on forthcoming releases. This is a fantastic technology product, from a fantastic company, in a fantastic time. You should check it out!
