In this short post I show how to analyze Veeam backup job selection with PowerShell. I share two simple code snippets.

vCenter does not start after changing DNS servers
Recently I had to change DNS server in a VMware vSphere vCenter Appliance (VCSA). Normally this works without further issues. This time it was different. vCenter services did not start after changing DNS servers. I describe in this short post what went wrong and how I could fixed it.
Comparison of vSphere Transport Modes
Each time I talk to customers at installation dates or health-checks, I spend some time talking about vSphere transport modes. These are: Direct Storage Access, Storage Integration (I take this as a separate mode), Virtual Appliance and Network mode. This is a topic with a lot of facets still not widely known. This comparison of vSphere transport modes is based on a few characteristics. I give some detailed information for Veeam […]
Does ESXi host survive persistent boot device loss?
In this post I investigate what happens when a VMware vSphere ESXi host loses its boot device. This device is meant to be a persistent device. For non-persistent devices like USB- and SD-card, behavior is quite clear: whole ESXi OS runs in memory, no mass-write operations should be directed to the device. When it breaks, ESXi isn’t missing it and keeps running.

PowerCLI Script to check if VMs get backed up by Veeam B&R
In this post I share a small PowerShell/PowerCLI script to check if VMs get backed up by Veeam B&R. If you do not run VeeamONE, it can be challenging to check if every VM that should be backed up, is really backed up. For checking this, this script should be helpful.
Poor SAN transport mode performance
These days I had to troubleshoot poor VMware vSphere SAN transport mode performance during backup with Veeam. Before SAN mode, NDB transport mode was used. NBD outperformed SAN mode totally!
