Using Workers in Veeam Backup for Nutanix AHV

Veeam workers are the VMs running in the Nutanix cluster used in large environments to speed up the backup and restore processes.

Veeam Backup and Replication manages those VMs. During backup or restore procedures, VMs are powered on to process the data, and when backup or restore is finished, they are powered off.

We can consider workers as temporary proxies, working only during backup or restore procedures.

In this article, we will look at how to add workers to the backup infrastructure and how it works.

Veeam Backup & Replication Instant Recovery to Nutanix AHV

I have previously written about how to connect VBR to a Nutanix cluster, as well as how to create backup tasks and restore.

In this article, we will talk about a very important VBR functionality – Instant Recovery, support for which was added with the release of Nutanix AOS 6.0 STS and AOS 6.5 LTS.

VMware ESXi 8.0 Update 2b is out

VMware ESXi 8.0 Update 2b is out and contains a lot of bug fixes. One of the fixes I want to mention is a bug in CBT:

Changed Block Tracking (CBT) might not work as expected on a hot extended virtual disk:

In vSphere 8.0 Update 2, to optimize the open and close process of virtual disks during hot extension, the disk remains open during hot extend operations. Due to this change, incremental backup of virtual disks with CBT enabled might be incomplete, because the CBT in-memory bitmap does not resize, and CBT cannot record the changes to the extended disk block. As a result, when you try to restore a VM from an incremental backup of virtual disks with CBT, the VM might fail to start.

As a workaround, there were two options: not to use hot extend and perform disk extend operations when the VM is powered off, or create periodically full backups to reset the CBT.

So, if you’re running ESXi version 8.0 Update 2, you should consider updating to the 8.0 Update 2b as soon as possible.

Veeam Hands‑On Labs

You may not know, but last year Veeam launched a set of Hands-On Labs (HOL) to demonstrate the product’s capabilities. One thing I like is that it’s not just a point-and-click Labs, but a whole preconfigured environment.

Example of labs available (and more):

Test drive Veeam Backup and Replication V12;
Test Drive Veeam Recovery Scenarios;
Protect and Enhance your Kubernetes applications with Kasten K10 by Veeam.

You can get access to the HOL as an End user and as a Partner as well.

Notice, that depending on the region the lab set may be different.

After registering to the Lab you will receive an email with instructions on connecting to the environment. It could take a while.

During the test, my overall experience was excellent. The HOLs has clear instructions and a non-lagging environment. So check this out.

Restoring Veeam Backup Server from configuration backup

Veeam configuration backup is an easy solution to back up your VBR server, including configuration, jobs, sessions, and more. If something goes wrong with a backup server, all you need to do is install a new one and restore the configuration from the previously created backup.

In this article, we will look at how to create a configuration backup of the VBR server, and how to restore when needed.

Backing up and restoring VMware vCenter Server. Part 2 – Veeam Backup and Replication

In the previous article, we talked about how to restore vCenter using native backup. In this part, we will talk about how to restore VMware vCenter Server using Veeam Backup and Replication.

Although restoring a VM using Veeam is a simple task, but when we are talking about vCenter Server a few moments should be considered.

Let’s get started.

How to backup Nutanix AHV using Veeam Backup and Replication 12.1 and Veeam Plug-In for Nutanix AHV v5

In this article, we will look at backing up Nutanix AHV virtual machines using VBR 12.1 and Nutanix AHV Plug-In v5.

The main difference between the v4 plugin and v5 is the possibility of creating backup jobs related to Nutanix AHV VMs right in the VBR console. You don’t need to connect to the backup appliance deployed in a Nutanix cluster to create a backup job.

Also, please make sure, that you’re using version 5.1 of the plugin or higher because of the critical bug found in v5.0.
