Let’s Encrypt Free Certificates in Windows for Veeam Cloud Connect

One year ago I built a complete and dedicated lab in order to permanently test and demonstrate Veeam Cloud Connect. The lab had been designed to operate as a production environment, and was also used for the Veeam Cloud Connect book I wrote. After a year, my SSL certificate was about to expire, so I had to either renew it, or find a different solution.

My previous certificate was a classic SSL certificate sold by one of the many Certificate Authorities available on the internet. I have nothing to complain about regarding my experience with them, the entire request process was quick and easy, and the certificate is universally recognized. My personal issue was just the price: at 249 USD a year, this was totally out of my budget. …

Backup and Change Rate, Part 2: Querying Change Rate

In this second part of the series we will discuss how you can manually check Change Block Tracking (CBT) via the Managed Object Browser (MOB). For the sake of simplicity everything in these examples has been tested against a standalone ESXi host, although this process should be quite similar if you use vCenter.

The vSphere API can be difficult to understand at first. However, VMware offers something called the Managed Object Browser, which basically allows you to browse the API and find out the structure of the API without actually doing any programming. In vSphere 6, MOB is disabled by default on an ESXi host. So you need to enable it. …

Backup and Change Rate, Part 1: Change Rate Explained

In this blog post series, we will deep dive into Change Block Tracking (CBT), how CBT works, how it is affected by growth and how this in turn affects image-based backup in Veeam Backup & Replication.

When you start using Veeam Backup & Replication (VBR) for the first time, the biggest difference with traditional vendors is quite apparent. You do not have to install anything inside the virtual machine (VM) you are protecting. Instead of processing the data inside the VM, VBR processes it from the outside, which means VBR does not deal with individual files, but with complete hard disks.

On the hardware side of things, disks are mostly defined by bytes, or rather, groups of bytes called blocks. These blocks almost always have a fixed size – the ‘block size’. So imagine you have a block size of 4KB and you have a hard drive of 1GB, that means you have 1GB / 4KB = 262144 blocks or 262144 groups each containing 4KB. So you can think of a disk as a single row matrix, where each cell is one block of 4KB. …
