Introduction

Veeam NAS and File Share Backups are a new capability in Veeam Backup & Replication V10. We can now backup SMB, NFS shares as well as file server sources. This means it covers Linux and Windows files servers and shares. It can also backup also many NAS devices. There are many of those in both the SME and enterprise market. I know it is fashionable to state that file servers are dead, But that is like saying e-mail is dead. Yes, right until the moment you kill their mailbox. At that moment it is mission critical again.

My first test results with the RTM bits are so good I doing this quick publish to share them with you.

Early testing of Veeam NAS and File Share Backups

As a Veeam Vanguard I got access to the Veeam Backup & Replication V10 RTM bits so I decided to give it a go in some of our proving grounds.

I tested a Windows File Server, a Windows File share and a General Purpose File Share with continuous availability on a 2 node cluster. All operating systems run Windows Server 2019, fully patched at the time of writing.

Veeam NAS and File Share Backups
These are your 3 major options and they cover 99% of file share uses cases out there.

Windows File Server

This is the preferred method if you can use it. That is if you have a Windows or Linux server as opposed to an appliance. The speeds are great and I am flirting with the 10Gbps limits of the NIC. As this is pure TCP it does not leverage SMB Multichannnel or SMB Direct.

9.9Gbps, 800-900MB/s, what is not to like about such early test results?

Windows File Share

With a NAS you might not have the option to leverage the file server object. No worries, we than use the File Share. If it is SMB 3 you can even leverage VSS if the NAS supports it. It might have the added benefit that you can add more file share proxies to do the initial full backup if so required. With File Server you are limited to itself. But it all depends on what the source can deliver and the target ingest.

Note that we use a SMB 3 file share here. With a properly configured network you can leverage SMB Direct and SMB Multichannel with this.

RDMA and Multichannel – gotta love it.

General Purpose File Share with continuous availability on a 2 node cluster

This one is important to me. I normally only deploy General Purpose File Shares with continuous availability anymore where applicable and possible. SMB 3 haves given us many gifts and I like to leverage them. The ease of maintenance it offers is too good not to use it when possible. Can you say office hours patching of file servers?

So here is a screen shot of a Backup of a General Purpose File Shares with continuous availability where is initiate a fail over of the file share. That explains for the dip in the throughput, but the backup keeps running. Awesome!

Our backup source fails over but the backup keeps running. That is what we like to see. All this also leverages SMB 3 Direct and Multichannel by the way.

Restores

Backups are cool but restores rule. So to finish up this round of testing we share a restore. Not bad, not bad at all. 221.9 GB restored in 5.33 minutes.

Speedy restores are always welcome

More testing to follow

I will do more testing in the future. This will include small office files in large quantities. These early tests are more focused on large image data such as satellite, aerial photography and mobile mapping images. An important use case, hence our early testing focus.

For an overview of Veeam NAS and file share backups as well as the details take a look here for a presentation on the subject by one and only Michael Cade at TFD20.

Conclusion

The Veeam NAS and file share backups in Backup & Replication V10 are delivering great results right from the start. I am happy to see this capability arrive. Without any doubt the only remark I have is that they should have done this sooner. But today, it is here and I am nothing but happy about this.

There are lot of details to this but that will be for later content.

Hyper-V Amigos Showcast Episode 20 and 21

Introduction

This is just a quick blog post to let you know the Hyper-V Amigos have released 2 webcasts recently. These are Hyper-V Amigos Showcast Episode 20 and 21. You will find a link to the videos and a description of the content below.

Hyper-V Amigos Showcast – Episode 20

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 (Azure Stack HCI). 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.

Hyper-V Amigos Show Cast Episode 20

Some extra information

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 show cast, 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.

Hyper-V Amigos Showcast – Episode 21

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
  • After that, we create the Veeam Agent Recovery Media (the most finicky part)
  • Finally, we restore one of the S2D hosts completely using the bare metal recovery option

Some more information

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.

We hope the show cast 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.

Conclusion

We will be doing more web casts on Veeam Backup & Replication v10 in 2020 as it will be generally available in Q1 as far I can guess.

Hyper-V Amigos Showcast Episode 20 and 21

But with Hyper-V Amigos Showcast Episode 20 and 21, that’s it for 2019. Enjoy the holidays during this festive season. The Hyper-V Amigos wish you a Merry X-Mas and a very happy New Year in 2020!

Optimize the Veeam preferred networks backup initialization speed

When Veeam preferred networks cause slow backup initialization speeds

When using preferred networks in Veeam you choose to use another than the default host network for backups and restores. In this post, we’ll discuss how to optimize the Veeam preferred networks backup initialization speed because we aim for optimal performance. TL-DR: You need to provide connectivity to the preferred networks for the Veeam Backup & Replication server. It seems a common mistake I run into every now and then. Ultimately it makes people think Veeam is slow. No, it is just a configuration mistake.

Why use a preferred network?

Backups can fill up a 1Gbps pipe very fast. Many people still use 1Gbps networking as default connectivity to the hosts. Even when they leverage 10Gbps or better it is often in a converged network setup. This means that only part of the bandwidth goes to host connectivity. Few have 10Gbps for “just” host connectivity. This means it makes sense to select a different higher bandwidth network for backup and restore traffic.

Hence for high volume, high-performance backup and restores it is smart to look for a bigger pipe to leverage. Some environments have dedicated backup networks at 10Gbps or better. But we find way more high bandwidth networks for other purposes. In Hyper-V environments, you’ll have those for SMB networking like CSV, Live Migration variants and storage replication. Hyper-Converged Infrastructure deployments use these networks for storage as well. With S2D you’ll find more and more 25/50/100Gbps. All these can be leveraged as a preferred backup network in Veeam

Setting up a preferred network

Setting up a preferred network is easy. First of all, you figure out which network to use. You then add those to the preferred networks as follows:

In file menu select “Network Traffic Rules”

Optimize the Veeam preferred network backup initialization speed

Click “Add” and specify the source IP as well as the target IP range. You can op to encrypt the traffic and /or set a bandwidth limit.

We have two SMB storage networks available, we enter both.

There is no need to have the preferred network registered in DNS. It will work fine without.

I hope it is clear that the source (Hyper-V Hosts), the target (backup repository or the extends in a Scale-Out Backup Repository) and any Off Host Proxies need connectivity to the preferred network(s). If you leverage WAN accelerators, Gateways Servers, log shipping servers than these also need access. Last but not least you should also make sure that the Veeam Backup Server (VBR) has access to the preferred networks. This is one that a lot of people seem to forget. May because it is most often a VM if it is not a shared role on the repository server or such and things do work without it.

When the VBR server has no access to the preferred networks things still work but initialization of the backup and restore jobs is a lot slower. Let’s test this.

Slow Initialization of backup and restore jobs

As a result of using preferred networks you might probably notice the following:

  • First of all, we notice a slow down in the overall initialization of the backup and restore job.
  • This manifests itself in a slow start of the actual VM backup/restore and reducing the number of simultaneous backups/restores of VMs within a job.

Without the VBR server having connectivity to the preferred networks

23:54 to complete the backup job (no connectivity to the preferred network)

Optimize the Veeam preferred networks backup initialization speed

With the VBR server having connectivity to the preferred networks. Notice how smooth and continuous the throughput is.

07:55 to complete the backup job (with connectivity to the preferred network) => 3 times as fast.

When you look into the Veeam backup logs for this job you will find at various stages attempts by the VBR server to connect to the preferred networks. If it can’t it has to wait until it times out. You see entries like:

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 10.10.110.2:2509 (System.Net.Sockets.SocketException)

Optimize the Veeam preferred network backup initialization speed
Just a small part of all the NetSocket time out you will find for every single VM in the job. Here VBR is trying to connect to one of the extends in the SOBR.

This happens for every file in the backups (config files and disks) for every extend in the Scale-Out Backup Repository (per VM backup chain). This slows down the entire backup job tremendously.

Conclusion

I always make sure that the VBR servers in my environments have preferred network connectivity. Consequently, initialization is faster for both backups and restores. Test it out for yourself! It is the first thing I check when people complain of really slow backup. Do they have preferred networks set up? Check if the VBR server has connectivity to them!
