Using Workers in Veeam Backup for Nutanix AHV

1 Reply

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.

Quick fix: Nutanix. Restore admin password

Leave a reply

It’s not a common situation, but it does happen sometimes, especially in test clusters.

To change the admin password we need to connect to the CVM, for example, using the nutanix user, and reset the password:

$ ncli user reset-password user-name=admin password=MyStrong@Passw0rd
Password of user 'admin' reset successfully
Please login again with new credentials.

The password should be strong and between 8 and 255 characters. It should differ by at least 4 characters from previous password and it should not be from last 5 passwords.

Now you can connect to Prism and use the password you just set.

Using SSH key-based authentication and Lockdown mode in Nutanix clusters

Leave a reply

Last year, a new check added to the NCC module may require your attention:

“Password-based remote login is enabled on the cluster. It is recommended to use key-based SSH access instead of password-based SSH access for better security.”

Although this check has a severity level of “Info”, if you dig a little bit deeper, you can find, that password-based authentication will be a deprecated authentication method since 2024. And we can only guess when key-based authentication will be not a recommendation, but a requirement.

In this article, we will look at Cluster Lockdown Mode and how to enable key-based access to the cluster.

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

Leave a reply

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.
