Infrastructure in a Nutshell
nutanix hycu

Today, I will present you the method of deploying the HYCU backup solution on my Nutanix AHV cluster.

In the previous article, I presented you the prerequisites necessary for installing the solution, including sending the HYCU installation files to the Nutanix AHV cluster. At this stage, you should therefore have the desired version of HYCU available on your cluster:

In my case, I have deliberately placed 3 different versions of the software in order to be able to show:

  • the deployment of the solution
  • the upgrade with upgrade path

Sizing

Before proceeding with the installation, it must first be sized according to our needs. For this, HYCU gives indications on VM sizes depending on the quantity of virtual machines to be backed up:

In my case, having less than 50 virtual machines to backup, I will go for the smallest size:

  • 8 vCPU
  • 8Gb RAM
  • 32Gb storage

Now that my VM is sized, let’s move on to its deployment.

Deploying the HYCU controller

To deploy the HYCU VM, you need to connect to the Prism Element, go to the “VM” menu and click on “Create VM”. In the window that appears, I give it a name and move on:

I enter the values ​​retained during dimensioning in the “Compute Details” section:

And then I add the first disk of type “DISK” as “Clone from Image Service” and select the image I previously loaded on my cluster “hycu-4.9.0-5310”:

I then add a second disk of type “DISK” this time, in “Allocate on Storage Container” since it is a blank disk of 32Gb that I place on the default storage container:

Finally, I assign a network card to my virtual machine on the subnet of my choice:

My virtual machine is now deployed, I can start it:

My next blog post will detail the initial configuration of the HYCU virtual machine which will allow to finalize the system initialization and access the solution administration interface.

In my previous article, I introduced you to the HYCU backup solution. I will now describe my deployment environment and explain how to retrieve the solution’s installation sources.

Deployment environment

My deployment environment is as follows:

  • Nutanix CE2.1 cluster to deploy and as a source for backups
  • Synology NAS as a destination for backups

This is enough to test the solution and simulate a real production environment.

I have already set up a share on the Synology NAS to receive the backups and I have made sure that the Nutanix cluster, the HYCU VM and the Synology NAS could communicate without any problem.

I will see later if I can simulate an additional S3 type location to simulate an externalization of data in “Archiving” mode.

Let’s now move on to recovering the files needed for the installation.

Solution Compatibility

In terms of compatibility, here are the main elements to keep in mind on the scope that interests us:

  • Nutanix AOS 6.5, 6.8 and 6.10
  • Nutanix Files 4.4 and 5.0
  • Nutanix Objects, Amazon S3, Wasabi
  • VM Windows Server 2016, 2019, 2022
  • Linux

I invite you to consult the compatibility matrix available on the HYCU Support site to learn about all the HYCU compatible platforms: https://download.hycu.com/ec/v5.1.0/help/en/HYCU_CompatibilityMatrix.pdf

Retrieving installation images

To retrieve the images, you must go to the publisher’s website and request a trial license: https://www.hycu.com/solutions/data-protection/nutanix#getForm

There are a few fields to fill in, a person from HYCU will then contact you by phone (so provide a number on which you can be reached!) to ask you what your motivations are.

Once all the prerequisites are filled in, HYCU will provide you with a download link that will allow you to retrieve the software installation image in qcow2 format, ready to be imported into your Nutanix cluster.

Transferring images to the Nutanix cluster

Once you have downloaded the qcow2 image from HYCU, you now need to transfer it to your Nutanix cluster.

To do this, connect to the Prism Element of your Nutanix CE cluster and go to “Settings > Image Configuration”:

Click on “Upload image”, fill in the form and select the previously uploaded image:

As this will be a prerequisite for future operations on your HYCU, I invite you to get into good habits right away and name your image according to the HYCU-VERSION-BUILD model.

Click on “Save” to start the transfer and wait until your image is processed by the cluster and is indicated as “ACTIVE”.

HYCU official documentation

For the official documentation from the publisher, it is freely available on the HYCU website in PDF format: https://support.hycu.com/hc/en-us/categories/15363454825500-Documentation

No translation other than English, so you’ll have to learn the language of Shakespeare!

There you have it, you now have everything you need to deploy the HYCU controller on your cluster, see you in a future article to find out how to deploy the controller.

In a world where data management is a major issue, companies are looking for efficient, simple and powerful backup and disaster recovery solutions. HYCU stands out as a backup solution specifically designed for hyperconverged environments, particularly Nutanix.

This article is the first of a complete guide on the HYCU backup solution, a guide that you can find with the other guides here: https://juliendumur.fr/en/guides/

Native integration with Nutanix

HYCU is the first backup solution developed exclusively for Nutanix. Unlike traditional solutions tailored to hyperconverged infrastructures, HYCU is designed to fully leverage the Nutanix ecosystem. It integrates directly with Nutanix AHV and Nutanix Files, ensuring optimal data protection without impacting system performance.

With its API-first integration, HYCU is able to align seamlessly with the Nutanix architecture. This allows IT administrators to manage backups and restores from the Nutanix Prism interface, providing centralized and intuitive management. This approach reduces the learning curve and limits operational efforts.

Key Features of HYCU for Nutanix

Unlike traditional solutions that require installing agents on each virtual machine, HYCU is based on an agentless approach, reducing resource consumption and simplifying maintenance. It is able to automatically detect workloads and adapt backup policies based on the defined configurations. This automation minimizes human intervention and reduces the risk of error.

One of HYCU’s strengths is its ability to perform granular (individual files, specific databases) or complete (entire virtual machines) restores in just a few clicks, ensuring rapid recovery in the event of a failure.

HYCU also integrates advanced data compression and deduplication technologies, reducing storage consumption and improving overall backup performance. Native integration of WORM locking also improves the immutability and security of backed up data.

However, HYCU is not limited to on-premises Nutanix infrastructures. It supports hybrid and multi-cloud environments, allowing companies to protect their data on AWS, Google Cloud, and Microsoft Azure. It is also capable of backing up VMWare ESXi environments or SaaS applications.

Unlike complex solutions requiring advanced configurations, HYCU offers a “plug-and-play” approach where setup and operation are accessible even to IT teams not specialized in backup. The intuitive user interface allows administrators to manage the entire backup and restore lifecycle in just a few clicks.

Use cases and benefits

Companies using HYCU for Nutanix benefit from optimized data protection without compromising the performance of their infrastructure. Key benefits include:

  • Reduced operational costs through simplified management and reduced storage requirements.
  • Significant time savings through automated and rapid restores.
  • Improved business continuity with rapid disaster recovery.
  • Regulatory-compliant protection through encryption and data retention features.

HYCU combined with Nutanix environments is a modern and innovative backup solution that is perfectly aligned with the principles of hyperconvergence. In the next article, I will present the different prerequisites necessary for deploying the solution.

After writing an update to the article on deploying the solution, here is the update on adding a source to your HYCU controller.

Prerequisites for adding a Nutanix AHV cluster

Among the first prerequisites, the Data Service IP must be configured on your Nutanix cluster:

To be able to add a Nutanix AHV cluster as a source on your HYCU controller, you will need an account capable of connecting to your cluster and to your Prism Central if you have one.

I recommend using a dedicated account and not using the admin account of your cluster whose password will change regularly.

Last point, obvious but always good to remember, the HYCU VM and your cluster / Prism Central must be able to communicate.

Once all the prerequisites have been met, you can proceed to adding the cluster to your controller.

Adding the Nutanix cluster to HYCU

On your HYCU interface, in the toothed wheel at the top right, click on source:

Add your Nutanix cluster (IP_ADDRESS:9440) with the service account that you have dedicated to HYCU then click on “Next”:

Repeat the operation if you have a Prism Central:

Your cluster is added to your controller:

You can find it in the “HYPERVISOR” tab of the “Sources” window:

And on the home page of your HYCU controller:

Your Nutanix cluster is ready to be backed up.

In my previous tutorial, I showed you how to deploy the HYCU solution on your Nutanix cluster. It is now time to add your cluster to the software administration interface so that you can backup it.

Nutanix: Create a dedicated user

It is strongly recommended to create a dedicated user on your Nutanix cluster to manage the backup part with HYCU. To do this, go to “Settings” > “Local Users Management” and click on “New User”:

Complete the form with “Cluster Admin” and “Backup” rights:

The rights must be configured with “Cluster Admin” and “Backup”. The “Backup” right alone will not allow the HYCU solution to function correctly. Save, we can now add the cluster to HYCU.

HYCU: Add a new source

To add a new source to HYCU, you must visit the toothed wheel at the top right of the interface, then click on “Source”:

In the window that appears, there are 4 tabs available:

  • Hypervisor: this is where we add the Nutanix or VMWare hypervisors which are to date the only compatible HYCU hypervisors
  • Cloud: to back up your Google Cloud or Azure environments
  • File Servers: intended for file servers including Nutanix Files, NetApp OnTap or Dell PowerScale
  • Physical Machines: to backup physical servers

The tab that interests us here is “Hypervisor”, click on “New” then fill in the different available fields:

Enter the URL of your cluster either in IP format as in my screenshot, or in HTTP format: https://ip-address:9440, as well as the login and password of the account previously created on your cluster.

Click “Next” to access the optional addition of Prism Central login information, fill out the form with Prism Central “admin” authentication information if desired, then click “Next”:

If you have correctly filled in the information from the previous forms, a validation message appears and you can save the configuration:

Your cluster is now added to your HYCU solution and you can start backing up your virtual machines:

Setup files download

We will start by retrieving the files necessary for deploying the HYCU solution directly from the publisher’s site.

To do this, go to: https://www.hycu.com/get/trial-start

Then select “Nutanix” in the Private Cloud & Data Center category:

You will then need to complete the following form:

Select Nutanix again from the list of available environments:

Then select the type of hypervisor installed on your cluster, in our case it is obviously the Nutanix AHV hypervisor:

PLEASE NOTE: I remind you that this tutorial shows how to deploy HYCU on a Nutanix Community Edition environment for homelab use. If you wish to put this solution into production, I invite you to contact a distributor of the solution in order to obtain a quote for a license adapted to your environment.

Finally click on “download .qcow2” to start downloading the image:

Now that the file is recovered, we can move on to the installation.

Prerequisites for deployment

Before deploying, we will ensure that our Nutanix cluster is ready to receive HYCU.

For sizing the virtual machine, you will need the following resources:

Given that we are in a lab context, the smallest sizing will be largely necessary. Make sure you have these resources available on your cluster before deploying.

A service account on the Nutanix cluster with “cluster admin” rights will also be required. On the Prism Element interface, in “Settings > Local User Management”, click New User:

Then complete the form before validating, remembering to check “Cluster Admin” in the “Roles” section:

Configuring the Data Services IP is also recommended. In “Settings > Cluster Details”, fill in the ISCSI Data Services IP field with a dedicated IP address (that is not yet assigned to other hardware):

You also need internet access and an available IP address for your HYCU virtual machine.

As for specific ports and other particularities, I will leave you the pleasure of going through the documentation: https://download.hycu.com/ec/v4.8.1/help/en/HYCU_UserGuide.pdf

Deploying the HYCU virtual machine

The deployment of HYCU is very simple and is divided into 4 steps:

To upload the image previously downloaded to your cluster, on Prism Element in “Settings > Image configuration”, click on “Upload Image”:

Remplissez le formulaire en veillant impérativement à nommer l’image créée comme le .qcow2 que vous téléchargez (dans le cas présent, il faut la nommer hycu-4.8.1-274) et cliquez sur Save :

You now have to wait while the image downloads. As soon as it is finished, in the “VM” menu, in the Table display, click on “Create VM”:

Complete the form fields as follows:

In the “Disks” section, click “Add new disk”, select “Clone from Image Service” and find the previously downloaded image:

Then add a second 32Gb disk:

Finally, in the “Network Adapters (NIC)” section click on Add New NIC and select a VLAN to which to connect the VM network card:

Now click on “Save”, the VM is now created, start it then open a console on it. On the first screen, select “HYCU Backup Controller”

On the following screen, fill in the requested information:

The software then applies the configuration provided and proceeds to finalize the installation of the VM. This may take a few minutes and the system will notify you once the installation is complete.

Then enter the IP address that you entered during configuration in your browser like this: https://ip-du-serveur:8443

Log in using admin/admin credentials to access the administration console.

Votre HYCU Backup Controller est désormais déployé. Nous verrons dans un prochain article comment réaliser les configurations de base (ajout du cluster, définition d’une destination, création d’une policies…).

HYCU is a global leader in multi-cloud backup as a service that aims to simplify data protection, storage and recovery for businesses.

Having a dedicated server under Nutanix Community Edition at home, I deployed a HYCU instance to perform backup tests.

I’ll show you how to add a Wasabi bucket on a HYCU instance to outsource backups. Wasabi is a low-cost, high-performance cloud-based S3-compatible enterprise storage object with no charges for data egress or API calls and no complex storage tiers.

Wasabi account creation

Wasabi is obviously a paid offer ($5.99 / To / month), but you have 30 days to test the service (without having to provide a means of payment).

To get started, you need to create an account with Wasabi: https://wasabi.com/sign-up/

Once the account is created, you have access to your Wasabi interface:

We can now move on to creating the bucket.

Wasabi bucket creation

To start creating the bucket, just click on “Create Bucket” on the home page of your space :

Then, enter the name you want to give to this bucket, select the region, note the DNS corresponding to the selected region and click on “CREATE BUCKET”:

The bucket now appears in the list of your buckets:

In order for HYCU to access this bucket, an access key must also be created.

Wasabi access key creation

To create the Wasabi access key, click on “Access Key” in the side menu :

Then on “CREATE NEW ACCESS KEY” at the top right :

Write down the access key and secret key somewhere because you won’t be able to view it afterwards:

The Wasabi part is over, let’s move on to HYCU.

Wasabi bucket setup on HYCU

On the admin interface of HYCU, in the left side menu, click on “Targets” and then “Add” on the top right.

Fill in the target name, enable compression and click “Next” :

Fill in the information requested, in particular the type, the target (which depends on the datacenter you chose when creating the bucket), the name you chose for your bucket and the access keys :

Click on “Save” once all the information has been filled in and if everything is good, your bucket is then added to the HYCU interface.

All you have to do is configure your policies to use this new bucket.

Creation of the HYCU policy

In the side menu, click on “Policies” then on “New” at the top right and fill in the configuration information you want to apply to this backup:

Validate then add VMs to this policy in order to protect them directly from the list of detected VMs:

Your virtual machines are now backed up to your S3 Wasabi compatible storage space.
