Note: this article has been updated by Linux versions supported by Veeam Backup & Replication (December 2024).

Veeam Backup & Replication has several roles and for some of them you can use a Linux OS to implement specific roles.

Considering that CentOS Linux 7 will reach end of life (EOL) on June 30, 2024 will be really important know which versions and which distributions are supported.

Like every hardware and software components, before apply a VMware vSphere upgrade or update you have to check all compatibility aspects.

One is related to the backup software that can be critical because you may loose the capability to perform backup and/or restore.

For Veeam Backup & Replication there is a specific Veeam KB (KB 2443) that provides information about compatibility between VMware vSphere and Veeam Backup & Replication.

Veeam Backup Catalog is a feature of Veeam Backup & Replication that stands for VM guest OS file indexing.

Veeam Guest Catalog service on backup server works as a local catalog service. It collects index data for backup jobs on this specific backup server and stores this data locally in the Veeam Backup Catalog folder. By default, the indexing data is stored in the VBRCatalog folder on the backup server. Veeam Backup & Replication creates the folder on a volume with the maximum amount of free space, for example, C:\VBRCatalog.

What is the four-eyes principle? The “four-eyes principle” (also know as the two-person rule) means that a certain crucial and critical activity (prone to human errors) must be approved by at least two people. This controlling mechanism is used to facilitate delegation of authority and increase transparency but also minimize errors or security attacks.

In Veeam Backup & Replication, starting with v12, is possible enable the Four-Eyes Authorization feature to protect some crucial operations.

GPU support in VMware vSphere has been for a while starting with the VDI scenario. But can GPUs be used in vSphere for applications other than VDI?

Using GPU not for graphics but for computing… because for some type of operation, GPU can be better than CPU. For example, machine learning models involve very large matrix multiplications and GPUs are designed to compute these operations much faster than CPUs.

VMware vSphere allows your end users to consume GPUs in VMs in the same way they do in any GPU-enabled public cloud instance or on bare metal.

A Data Processing Unit (DPU) is a programmable computer processor that tightly integrates a general-purpose CPU with network interface hardware.

In VMware, starting with vSphere 8.0, DPU can be used to offload workloads from an x86 host to a DPU, as well as providing an additional layer of security by having an air-gapped environment running some of the processes. This is the result of Project Monterey.
