Hyper-V Amigos Show Cast – Episode 21 – Bare Metal Recovery of an S2D node with Veeam Agent for Windows Integrated in Veeam Backup & Replication

Hello everyone! Carsten Rachfahl and Didier Van Hoye, aka “The Hyper-V Amigos” created another Hyper-V Amigos show cast just before X-Mas 2020. In episode 21 we are diving into leveraging the Veeam Agent for Windows integrated with Veeam Backup & Replication (v10 RC1) to protect our physical S2D nodes. For shops that don’t have an automated cluster node build processes set up or rely on external help to come in and do it this can be a huge time saver.

We walk through the entire process and end up doing a bare metal recovery of one of the S2D nodes. The steps include:

  • Setting up an Active Directory protection group for our S2D cluster.
  • Creating a backup job for a Windows Server, where we select failover cluster as type (Which has only the “Managed by Backup Server” as the mode).
  • We run a backup
  • We create the Veeam Agent Recovery Media (the most finicky part)
  • We restore one of the S2D hosts completely using the bare metal recovery option

Now we had some issues in the lab one of them suffering to a BSOD on the laptop used to make the recording and being a bit too impatient when booting from the ISO over a BMC virtual CD/DVD. Hence we had to glue some parts together and fast forward through the boring bits. We do appreciate that watching a system bot for 10 minutes doesn’t make for good infotainment. Other than that, it went fine and we were able to demonstrate the process from the beginning to the end.

As is the case with any process you should test and experiment to make sure you are familiar with the process. That makes it all a little easier and hurt a little less when the day comes you have to do it for real.

This is probably our last show cast for 2019 and we hope it helps you look into some of the capabilities and options you have with Veeam in regards to protecting any workloads. Long gone are the days that Veeam was only about protecting virtual Machines. Veeam is about protecting data where ever it lives. In VMs, physical servers, workstations, PCs, laptop, on-prem, in the cloud and Office 365. On top of that, you can restore it where ever you want to avoid lock-in and costly migration projects and tools. Check it out.

The Hyper-V Amigos wish you a very happy New Year in 2020!

Hyper-V Amigos Showcast – Episode 20 – Windows Server 2019 as Veeam Backup Target Part II

Hello there! Good to see you are back for more Hyper-V Amigo goodness. In episode 20 of the Hyper-V Amigo ShowCast, we continue our journey in the different ways in which we can use storage spaces in backup targets. In our previous "Hyper-V Amigos ShowCast (Episode 19)– Windows Server 2019 as Veeam Backup Target Part I" we looked at stand-alone or member servers with Storage Spaces. With both direct-attached storage and SMB files shares as backup targets. We also played with Multi Resilient Volumes.

For this WebCast, we have one 2 node S2D cluster set up for the Hyper-V workload. On a second 2 node S2D cluster, we host 2 SOFS file shares. Each on their own CSV LUN. SOFS on S2D is supported for backups and archival workloads. And as it is SMB3 and we have RDMA capable NICs we can leverage RDMA (RoCE, Mellanox ConnectX-5) to benefit from CPU offloading and superb throughput at ultra-low latency.

The General Purpose File Server (GPFS role) is not supported on S2D for now. You can use GPFS with shared storage and in combination with continuous availability. This performs well as a high available backup target as well. The benefit here is that this is cost-effective (Windows Server Standard licenses will do) and you get to use the shared storage of your choice. But in this ShowCast, we focus on the S2D scenario and we didn’t build a non-supported scenario.

You would normally expect to notice the performance impact of continuous availability when you compare the speeds with the previous episode where we used a non-high available file share (no continuous availability possible). But we have better storage in the lab for this test, the source system is usually the bottleneck and as such our results were pretty awesome.

The lab has 4 Tarox server nodes with a mix of Intel Optane DC Memory (Persistent Memory or Storage Class Memory), Intel NVMe and Intel SSD disks. For the networking, we leverage Mellanox ConnectX-5 100Gbps NICs and SN2100 100Gbps switches. Hence we both had a grin on our face just prepping this lab.

As a side note, the performance impact of continuous availability and write-through is expected. I have written about it before here. The reason why you might contemplate to use it. Next to a requirement for high availability, is due to the small but realistic data corruption risk you have with not continuously available SMB shares. The reason is that they do not provide write-through for guaranteed data persistence.

We also demonstrate the “Instant Recovery” capability of Veeam to make workloads available fast and point out the benefits.

We put in this kind of effort to make sure we know what works and what doesn’t. To be better prepared to design solutions that work, even if they require a bit “out of the box“ thinking. We don’t make decisions based on vendor marchitecture and infomercials. We contemplate on what solutions might work and test those. That is how we deliver better solutions, better results, and happier customers. We hope you enjoy our musings and efforts and wish you all a very end of 2019 and a very happy new year in 2020!

Your humble Hyper-V Amigos
