How to automatically remove VMs from backup

by

It’s been some time since my last blog post in general, and a lot of time has passed since my last Veeam blog post in particular. I just recently stumbled across something in Veeam Backup & Replication that I wanted to share with you. When you check my latest home lab generation (I did a rebuild and also exchanged some coins for refurbished hardware), you can see that there was something going on.

But why am I talking about Veeam Backup & Replication? Well, because I’m using it in the free “Community Edition” for my homelab. And because I still love Veeam. And when I read social media posts like this one, then I get watery eyes.

What is this Community Edition?

With this free gift from Veeam, you can protect up to 10 workloads. No matter if on VMware or Hyper-V, you can protect Windows and Linux servers, laptops, NAS, and more. You can enjoy (more or less) all the awesome features of the Enterprise edition, like:

  • Effective protection for virtual and physical workloads on-premises
  • Restore VMs quickly and get fast granular file and application-item restores with Veeam Explorers for Microsoft applications
  • Create bootable copies of workloads onsite or in offsite locations for migration and disaster recovery
  • Restore and/or migrate on-premises Windows/Linux VMs, physical servers, and endpoints to AWS, Azure, and Azure Stack
  • Verify that backups are free of malware before restoring them to production
  • Simple and powerful file protection of unstructured data through an easy-to-use wizard-driven approach
  • And many things more!

Sure, some really cool stuff is limited to the Enterprise edition (like various storage integrations, etc.). But still, it’s an awesome piece of software that’s free forever (the Community Edition), and fits perfectly for homelabs.

But enough marketing, you know the good stuff anyway. Let’s get back to the topic.

I’m building a new old computer

by

Yes, you’ve read that correctly. The title is confusing. I’m building a new old computer. Usually, something is new or old, but it can’t be both. But this time it is indeed both. It’s not directly Schrรถdinger’s computer, both old and new at the same time. But I think you’ll get the point.

Before we go into this topic: it has nothing to do with virtualization. Well, technically. But first things first.

Many moons ago I stumbled across some Tweets (that was before it was called X) of people gathering old hardware. Pentium III CPUs, old graphics cards like the Voodoo series, or Creative SoundBlaster sound cards. And for sure the very legacy beige computer cases. The good old stuff we all remember. The seed of building such an old computer has been planted a long time ago. And it germinated, grew, and now the young plant is blooming.

I didn’t start directly with gathering hardware and buying shedloads of old stuff. No. I first did some trial & error in my vSphere homelab. Yes. You can install Windows 98 as a virtual machine on your vSphere environment. I’m not saying you should, but it’s possible to do so. Unfortunately, you won’t have sound output, at least as far as I was able to test. So I moved on and set up a virtual machine on VMware Workstation. After installing the right sound driver, there was that iconic Windows startup sound. Oh, how I loved it!

New homelab hardware installed – HP Z8 G4 workstation

by

I may have skipped some homelab generation upgrades in my documentation here. However I have updated the page as far as I could, and I would like to provide you with a brief update on my current homelab setup with this blog post as well.

Last year, my wife and I moved into our own house. Yes, I married my love and we built a house. I didn’t shout about it because it’s something personal and I don’t have to rub it in everyone’s face. But yes, I’m a married house owner now and a loving father. Oh, I forgot to mention that my wife gave birth to a beautiful son this year. So many things happened! But anyway, back to topic.

You may have seen some images I posted on Twitter last year, about the huge IT rack I got my hands on, and the first “production” deployment in my new homelab rack. This “production” deployment was an actual beer fridge that was small enough to fit into that rack. If you don’t believe me, please go ahead and check the pictures here. The beer fridge is still there, but the huge and heavy IT rack has gone. The huge rack has been replaced by a desktop-size rack from StarTech.com. This rack is enough to provide a nice mount for my SuperMicro servers and networking equipment.

But the main topic in this blog post is the recently acquired hardware. I bought a refurbished HP Z8 G4 workstation!

Veeam Agent for Microsoft Windows – The network location cannot be reached

by

This blog post is the first with Veeam as a topic for years! I can only hope that it helps at least some people struggling with the same problem I had.

I’m a PC gamer. Still. When I find some time for fun and games, you may find me on the grounds of Battlefield 2042, or maybe I’m driving a tractor in Farming Simulator 2022. My gaming computer is still capable of playing the most recent games. Maybe not with the best graphics and most recent graphic technologies, but they run and make fun.

Anyways.

On this gaming PC, I’ve installed the Veeam Agent for Microsoft Windows (the free one). Since ages. It works well, but sometimes, the backup fails. Even if you have your games available on demand to be downloaded at any time (Steam, EA, Ubisoft, etc.) and don’t need to install the games from DVDs anymore, it is still annoying if your disk goes bad or something screws up your Windows. I’m using a Synology NAS as my backup target, connected over a 10 Gbit/s ethernet link. The computer itself is equipped with some Samsung NVMe SSDs, so even a full backup is done pretty quickly.

The point is that the computer always takes some time until the network connection is ready and working fine. That’s by design. You log in with Windows Hello, for example, the Desktop is loading, and somewhen the LAN connection is also ready. But Veeam Agent for Microsoft Windows already started its job (in case it’s scheduled and if it has missed that time slot) before the network is ready. And this job will fail because the network is not yet ready.

Error: [PCNAME] Failed to get disk free space. The network location cannot be reached.

I searched for a while on the internet and stumbled across a Veeam forum post. There they mentioned enabling the “When backup target is connected” function.

I enabled this feature and tried it out. It worked.

The backup job will now usually succeed.

Yes, usually. Veeam Agent still starts the job before the network is ready (directly after logging in to Windows). And this job may fail. But the job will start again as soon as there is connectivity to your NAS (SMB share). And this time, the job runs just fine and successful.

New Year – New Hosting?

by

To make the long story short: this week I moved my blog to a new web host. And I was surprised and pleased with how well and smooth everything went. But I’ll don’t just let you alone here. I’d like to explain the how and why I moved.

When I started with WordPress as my blogging platform, it was all just fun and games. Nothing technical, no helpful blog posts, just tinkering around, having fun writing. But with my engagement in the IT community, with my career in IT, I have rethought. I stopped playing around, and I started writing actual helpful blog posts. I started to write in German because this is my native language. At some time I switched to English, not without a reason (or more actually more than one). I have often dealt with English-speaking customers, with hotlines from international companies. And today at my current employer, English is the de-facto standard when opening tickets internally, or talking to other people in different time zones. I switched to English because most of the IT people I know, personally and on various social media, are native English speaking or understand English. Maybe I also switched because of reaching more people with helpful blog posts. And when I check the blog statistics, most visitors are from the United States. So, not a wrong decision at all, switching to English.

But enough of the forewords.

The why

When I moved my blog from one host to the other back in the days, I was looking for more speed. If you know WordPress, then you know it’s all PHP and MySQL, which can be highly dynamic content. And from a webserver perspective, dynamic content can’t be delivered as fast as static content. But, in my humble opinion, that was back in the days when there wasn’t much SSD storage in the webservers, or it was expensive, or with old PHP versions, etc.

My previous web host had also WordPress, but not the traditional way. He offered static WordPress hosting, which made me curious, and I wanted to give it a try. You’ll get a WordPress instance which you can start whenever you want, write your blog posts, do the other stuff, and shut it down. After that, you’ll create a so-called artifact, which renders all the dynamic content from your blog into static files. All your text, CSS, and JS files, images, etc. will then be put onto Amazon CloudFront automatically. And that’s the static content you’ll get presented when visiting the website. The performance was good, good enough for me.

But it has also some downsides. Some native WordPress features, like comments, search, or some plugins, just don’t work like this. They can’t be static because they relate to the dynamic WordPress in the backend. I had to find solutions for many problems. And I’m still not sure, even if I was able to test it successfully if it really worked.

I decided to move back to my original web host, where I have my domain running since 2008. Not only because of that but also because of the aforementioned circumstances. I’m also born in Switzerland, and my blog has a Swiss TLD (.ch), but with that TLD it’s still (highly) visible also international. My new web host caught me with a good hosting package, which has 250GB of website storage and is backed by 100% NVMe SSD, with Nginx and Apache running in parallel, 50MB of Nginx cache, and many other things. And that for a reasonable price, at least by Swiss standards. Yes, it may be true that many things are more expensive in Switzerland than abroad. But not everything.

That’s the why.
