These days I reviewed a few PowerShell scripts for Veeam Backup & Replication I created some times ago. Long before v12 went GA. I want to share the changes in Veeam v12 PowerShell Module that made scripts crashing or, even worse, lead to total wrong results. Currently I found two areas with important changes in the Veeam VBR PowerShell module. SureBackup and querying for backup […]
Recently I wrote a detailed blog post about VMware Tools and the options available to update them at scale. Because this post was published on VMware’s blog Customer Experience and Success, I cannot publish the same post here. Therefore, I am summarizing my article here and providing the link to it. The first part deals with understanding VMware Tools Updates. It focuses on compatibility, what […]
Veeam SureBackup is a powerful feature when it comes to backup verification. Out of the box, it can test well know ports and applications like Microsoft SQL Server. You can also add custom scripts built to verify own applications. This post is about using a custom PowerShell script with SureBackup. There is also a sample script included that is able to test if all defined […]
If you read these lines, your probably know the Veeam Backup & Replication (VBR) feature SureBackup. It is a perfect tool to verify backups of well known applications within your organization. SureBackup can perform a lot of different tests while VMs are running in an isolated environment. You can also use custom scripts for further testing. But how to test all other VMs? These Simple […]
Veeam Hardened Repository makes it rather hard for a hacker to delete your company’s backup restore points. Therefore we love it! But what can we do for freeing space in Veeam Hardened Repository? This can be necessary if repository is almost full. I will show in this post what works and what doesn’t
This post is about a feature of the Veeam Hardened Repository. It is about the ability to extend the immutable time of existing restore points. Veeam made this possible by using PowerShell. See here how to change expiration date of restore points in Veeam Hardened Repository and what’s new in v11a.
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.
When enabling the ESXi Side-Channel-Aware Scheduler (L1 Terminal Fault vulnerability CVE-2018-3646) for a cluster or single hosts, you should use VMware HTAware Mitigation Tool for resource analyzing and enabling. There are a few limitations after applying and enabling VMware L1TF patches on ESXi hosts (starting in august 2018). One of them is that a VM configured with n vCPUs can only run on hosts with >=n physical cores. […]
Here is a very simple linux bash script to shut down all VMs of a ESXi host and the host itself, for example when a power failure occurs, this script can be used in UPS software. Some time ago a posted how to use such script in an HPE UPS environment. You can find the post here.
