When I try to upgrade from 12.2.0.334 to 12.3.1.1139, we receive the error "An error has occurred: The system cannot open the device or file specified." We are waiting for your help on the subject.  

Hi,  I do a Backup from a Phyiscal Maschine and try do restore it by Veeam Backup and Replication. Of course the PMaschine has 8 Cores, the proxmox SVR just have 4 Cores. I got the error message “Failed to reach the hypervisor. Error output: MAX 4 vcpus allowed”. Is there any solution? I have no possibility to change the vm config bevore create.  Thanks for any help.

Hi all,We are currently facing an issue during the installation of CDP (Continuous Data Protection) in our vSphere 8.0.3 environment. Setup: Hosts are updated exclusively using offline ISO images ISO files are internally validated and approved via change control Online depots are completely disabled vLCM is configured with only our custom HPE ISO (VMware-ESXi-8.0.3-24674464-HPE-803.0.0.12.1.0.11-apr2025.iso) vCenter version: 8.0.3 Hosts affected: esxi03.cloud.local (and others) Problem:When attempting to install CDP, remediation fails with the following error: Host 'esxi03.cloud.local' was not processed, the reason: 'Failed to validate the checksum of VIB 'http://hostupdate.vmware.com/soft

This is part three of three addressing general topics of environmental architecture for backup systems.In part XVI, we examined considerations for the placement of individual backup components, hardware configuration, and fault tolerance (Point 1 and 2 of the following list of major threats).In part XVII, we examined considerations for locations and site redundancy (Point 3 to 5 of the list of major threats).In this part, we address the aspects of ransomware, malware, theft and threats by insiders. These are points 6 to 8 on the list of major threats to backup environments that we identified in the last part. What are the main threats to backup data? Wrong placement of backup environment components Hardware damage to backup systems Power outages or disasters at one location Power outages or disasters at multiple locations External locations for backup data Ransomware attacks

Hello Veeam Community!As many of you know, I’m a huge fan of the community and love following all the awesome content you share. I’ve noticed that outdated Veeam logos or visuals sometimes pop up, so to help everyone stay up to date and keep things fresh and professional, I wanted to share where you can find the latest Veeam brand assets that you can use whether you’re publishing videos, posts, or articles on our blogs. We all loved the old logos, but yes, we are moving forward and modernizing not just our products but also our image. Here are some examples of the old logos you DO NOT want to use if you want to keep your communication fresh and modern. And this is our new, fresh, and cool example of the logo you would like to use. 😎

I have been using Synology NAS devices for a few years now and was lucky enough this year to get my hands on a new DS925+.  They removed the 10GB option from this one but there is dual 2.5GB ports which you can bond.  Find my blog post below and the link as well.  Enjoy.Synology DS925+ – Installation & Setup Synology DS925+ – Installation & Setup Over the last couple of years, with the help of Synology, I have been able to secure a DS920+ along with a DX517 expansion & a DS923+ NAS unit, which I have written reviews about.  Fast forward to 2025, and I was again in touch with Steph Clayton at Synology, who graciously helped me secure a DS925+ NAS for testing and blogging.

Hi Team,I have two servers with 100TB each with windows server operating system using as a file servers. one is acting as a primary servers and second is acting as a secondary server by using native replication. Now I wanted to add a third server with 200TB acting as a backup server.Can this can be achieved with the 1 pack of VUL of VDP??Many Thanks-Siddhartha 

Does it make sense to use a separate vCenter with one ESXi host for SureBackup, or can SureBackup be configured on the production vCenter, just using a dedicated ESXi host for SureBackup?

Creating architectural diagrams is challenging for everyone, not just Backup engineers. While you can find Veeam colors and icons at https://www.veeam.com/company/brand-resource-center.html, these resources may change, making it difficult to keep designs current. I found updating most of the Veeam Best Practice guide diagrams—like those at https://bp.veeam.com/vbr/Support/S_Vmware/backup.html—to be especially time-consuming and frustrating. I am continually seeking innovative tools to enhance my workflow. Recently, I discovered pikchr, wh

After the latest FW/Software update on our Exagrids, veeam started trying to use the management network for backups. I was told be exagrid support that veeam tries to use any available address and thus was grabbing an address that was not configured for backups on the Exagrid. How to I use network traffic rules to force Veeam to use a specific network?Bogus IPs for this discussionVBR server is running on 192.168.30.xExagrids are running on 172.16.30.x 

These diagrams are a sample of what I am working on in PowerShell for the next version of the Veeam.Diagrammer module.

We back up to disk then duplicate to tape for offsite storage. Not quite ready for cloud backups yet. I am wondering if anyone has any experience with Quantum LTO-9 tape drives with Veeam backup. I have quotes for two models. TD-L92BN-AR and TD-L93CN-AR. Thanks.

At VeeamOn 2025, Scality announced a unified software appliance with Artesca Object Storage and Veeam Backup bundled inside as a VM on Kubernetes via KubeVirt. Since this is a software appliance it allows you to use the hardware of your preference but have a simplified deployment and management. The current version is using a Windows Server, either 2022 or 2025, and Veeam 12.3. In the future, the Veeam Software Appliance (v13 on Linux) will also be an option.Recently this has passed Veeam Ready qualification as a repository and for object storage: https://www.veeam.com/solutions/alliance-partner/integrations-qualifications.html?alliancePartner=scalityIn the Service Provider space at Veeam, I have h

The number of VMware-based public cloud offerings continues to grow. Whether it’s to support cloud migration, reduce data center footprint, or simplify operations, more organizations are looking at running vSphere in the cloud. Some of these platforms have been around for years, while others are newer or just starting to see broader adoption. Even though they all run VMware, not every cloud platform gives you the same visibility or control — which makes a difference when it’s time to plan for backup and recovery. To help clarify what’s possible, I pulled together a matrix comparing the major VMware public cloud platforms — AWS, Azure, Google Cloud, IBM, and Oracle — and how Veeam fits into each one. AWS – VMware Cloud on AWS (VMC)A managed SDDC running on AWS with some restriction

Hi all, I hope you’re well,I require assistance in sizing the backup repository storage capacity for a VM workload running on vSphere with approximately 14 TB of source data. The backup repository well be hosted on a deduplication appliance either Dell EMC Data Domain or ExaGrid.The backup policy includes:7 daily incrementals5 weekly full backups 6 monthly full backups With offloading to azure blob storage cool tier and subsequently azure archive tier.Could you help calculate the actual storage capacity required on the support this retention policy, considering deduplication and compression ratios best practices?

HelloI have 4 VM on 4 different physical servers with Veeam Backup&Replication community edition v12.1.56.In my system, I have a VM under debian 12 which is used as Postfix SMTP relay for all my servers. Internally, everything goes through port 25 and all my servers send mail to this relay without identification or password. The relay then sends everything to my dedicated office365 mailbox.In less than 1 day, 2 of my Veeam VMs stopped sending me mail.So every time I run the test mail, I get the message: Unable to connect to SMTP server because of invalid credentials or connection settings.I've compared the smtp configuration with that of the 2 servers that are still working, apparently I haven't seen any anomalies and everything is identical. Even firewall configurations are perfectly identical between servers:SMTP Server (Basic authentication)SMTP server: IP of my SMTP serverFrom: mail address of my server adminT

I have an infrastructure operating on a Nutanix Cluster and Prism Element, and I have integrated it with VEEAM Backup. I possess a socket-based license for VEEAM, and the cluster appears online in VEEAM. There are about 15 VMs in my infra, and I have set up a job to back up all the VMs which are within the cluster, I start the job and observed that it is not utilizing the socket license. Instead, it's recognizing an instance-based approach and only backing up a few VMs, with the rest displaying a license overutilization error. Can any one let me know How Nutanix works with VEEAM, is it a socket based license or instance based license only.

I have one Veeam job to backup my VM with only selected disk selected and this job already runing for several months and the full backup size is 30TB. The retention for this job set to 2 days.Last friday i remove 3 HDDs from the Veeam Job and this 3 disks exclusion have capacity 8TB.Today i check why the full backup still 30TB and not decreased even 3 disks already take out from the job? 

In an era defined by ever-expanding data footprints and rapidly evolving application landscapes, traditional backup architectures often strain under the demands of modern enterprises. Organizations must not only safeguard data but also build backup infrastructures capable of growing seamlessly alongside their data volumes and adapting to shifting business requirements. A future-proof backup environment relies on scalable designs, cloud-native integrations, and automation to deliver reliable protection, efficient resource utilization, and consistent recovery performance. The Imperative for Scalable Backup SystemsEnterprises today generate data at an unprecedented pace. Every transaction, log, telemetry feed, or multimedia asset contributes to a mounting store of information that must be preserved for operational continuity, compliance mandates, or analytics purposes. A backup solution that cannot expand gracefully will quickly become a bottlene

Hello community, I would like to share a scenario of switching from Reverse Incremental mode to Forever Forward incremental mode, when changing a repository for Veeam backups. Whenever I am seeing Reverse incremental mode configured, it generally means, that a daily offload of full backups to tapes is needed. However, when using immutability on disk storage, Reverse mode is, generally, not supported. It is not supported on VHR and the option to enable when targeting an Object Storage repository is completely missing. Which will also become the standard in v13.  Jobs do not need to be recreated, they will switch automatically to incremental mode. If offloading daily full backups to tape is still a requirement, then another way to achieve it is to use Forever Incremental Mode, meaning without enabling periodic full backups

Hi everyone, how are you? I have a customer who has multiple M375 tenants.For example:Main tenant - 200 users Tenant Egge Unit 1 - 50 users Tenant Edge Unit 2 - 50 users We understand the limitations- It's not possible to restore between tenants- It's not possible to distribute licenses between tenants However, we can manage tenants from the same console, as mentioned by​ @MicoolPaul  in the post below. The customer's big question is: If I delete a tenant (this is common in edge units), will I lose all the licenses associated with that tenant? I'm thinking about the possibility: Or can we open a case with Veeam to "unlink" these licenses from the tenant so I can

Over the past few weeks, I’ve had numerous conversations with customers about how to protect Microsoft SQL Server with Veeam. Whether it's running on-premises, in Azure VMs, or as a fully managed cloud service, SQL Server plays a mission-critical role in countless organizations — and making sure it’s protected and recoverable is non-negotiable. But here’s the thing: there’s no single “right” way to back up SQL Server with Veeam.No one method is universally better than the others — it all comes down to your infrastructure, operational preferences, and recovery goals.So, to help make sense of the options, I’ve broken down the different ways Veeam supports Microsoft SQL Server backups, organized by where your SQL Server is running.On-Premises Microsoft SQL Server:Agentless Image-Level Backup (VM-Based)This is the simplest and most common approach for virtualized environments (VMware vSphere

OverviewI was recently working with a customer on migrating some Rocky Linux VMs running on vSphere hosts to some Hyper-V hosts using Veeam Backup and Replication.  After the migration to Hyper VM, the customer received the following error when the VM tried to boot. The issue is that the VM can’t boot in Hyper-V because it is having trouble finding the boot image and mounting the root file system. On further inspection, it was discovered that the Linux VM was missing the required Hyper-V drivers.  

When VBR start the job then VBR will create VM snapshot, but the snapshot failed due insufficient free space at source datastore. Anyone know are we can change the esxi snapshot location to other datatore?
