Hello dear community. I hope you are all well and can support me if necessary.I want to add my Proxmox HOST with the new version 12.2.0.334 and always get the following error message, which gives me no information at all about what is wrong.Error message:An unknown Proxmox VE Error has occured - screenshot attachedDo I need to configure anything else on my Proxmox host so that I have the option of adding the HOST to VBR?I would be very grateful for your support! 

Hi there Veeam community! Quick check if anyone has had a similiar scenario:A Customer has a Proxmox Cluster consisting of three nodes. They have been using Proxmox Backup Server (PBS) and intend to use Veeam going forward (they still have an active license from a retired system). Now at the same time, they want to continue using PBS (because it has specific features they like and 2x the backups are better).Question: Is there any chance of anything breaking or getting corrupted? I have had the same configuration running in our lab and it all went smoothly (of course the backups have to run at different times and not be allowed to interfere with each other). Any input would be highly valued!

We’ve deployed Veeam Backup for Azure.There are polciies in the Azure environment that deny public access to resources. Everything needs to be connected via private endpoints.The Veeam resources are deployed in a seperate subscription and seperate VNET. This VNET is peered with a hub VNET. Alle the production VNET’s are also peered with the HUB VNET. Taking backups within the subscription (and VNET) works. By using the disk access resource created by Veeam.Taking backups of resources (VM’s) in other subscriptions (VNET’s) does not work.We asume the backup should be done with a disk access resource in the production VNET. But Veeam does not create these disk access resources in the production VNET.Or the existing Disk access resource (in the Veeam VNET) should have a private endpoint in all the production VNET’s? Does anyone have experience with a similar private deployment where public access is blocked? This

How Does Veeam SureBackup Work? Veeam SureBackup leverages Virtual Lab technology to create an isolated environment where backups can be tested without impacting production workloads. This ensures backup integrity and recoverability by automatically booting virtual machines (VMs) from backups and performing a series of validation tests. Below are some core Components of SureBackup;Virtual Lab: A sandboxed environment where VMs are powered on for testing. Application Group: A set of dependent VMs required to validate specific applications or workloads. SureBackup Job: The automated process that boots the backup and runs integrity tests.Below is the “SureBackup” testing process. Once configured,

I’ve registered for VeeamOn 2025 and paid, trying to sign up for sessions but cannot figure it out. I can get a list of sessions but don’t see an option to register. Any assistance would be greatly appreciated.

We know that Veeam Backup & Replication can back up virtual machines. This is one of the main functions of Veeam and it has the most features and options that we can configure. Normally, when we are starting in the backup area and taking the first steps in data protection, one of the features that ends up going unnoticed is Application Aware.So, application Aware is a function that we can configure in our backup jobs. It allows us to consistently create backup. Consistent Backup But after all, what is consistent backup?

I previously shared a blog post on the Linux ISO, and I’d like to share an insightful LinkedIn post by Anton Gostev. Veeam’s managed Hardened Repository ISO, introduced five months ago, has been incredibly successful and is evolving further with Veeam Backup & Replication V13. Here are the key updates:End of the Separate ISO: The Hardened Repository ISO will be integrated into the platform via the new “Just Enough OS” (JeOS) ISO, which will enable deployment of various backup roles, including the hardened repository. Centralized Updates: JeOS will manage and update the OS and Veeam components across all backup infrastructure roles, simplifying maintenance with automatic patching during scheduled windows. Easier Provisioning: V13 removes the need for complex passwords in setting up a hardened repository. It will use thumbprint verification and a temporary PIN code for re-pairing with backup servers.

Hi everyone,It's being a while since this idea came to my mind, I want to be notified differently that mail, more accurate and clean, my mailbox is always a mess, and I get too much mails to read them all, and start pending on critical alerts and other stuff.I put together a powershell script, a schedule task and a few things in Windows Server where my Veeam B&R V12 is installed, and I managed to receive in a telegram bot the windows events related to Veeam tasks.Very basic, Im not programming skilled or anything like that, do you want to help and contribute to improve and develop this idea?here I share what I've done and shared to anyone who wants to help, participate and use this workaround.I created a Telegram Bot with BotFather, here the link With n

I actually wanted to present AsBuiltReport.Veeam.VBR in a recap article on my blog, but in the last few days I had the opportunity to use the package again in another productive infrastructure and came to the decision that a complete article must be provided here! Because this product is simply awesome! The subtitle on AsBuiltReport "Document Your Datacenter With PowerShell" says it all, but see for yourself… A few months ago I reported on the Veeam.Diagrammer (also included in the AsBuiltReport.VBR) in my Recap #4, which w

Hi,I am getting this error:Failed to prepare guest for hot backup. Error: VSSControl: -2147212522 Backup job failed. Discovery phase failed. Cannot start empty snapshot set. VSS error: VSS_E_SNAPSHOT_SET_IN_PROGRESS. Code:0x80042316.I’m aware this is a VSS related error and have been trying to work with this for a while. It happens on one of our servers every 3 or 4 days. It seems something is using the VSS service at the same time as the backup. The Veeam tech article about it so helpfully recommends ensuring your backup is not running at the same time as other backup or VSS related services. Yeah, got that!There aren’t, at least as far as I’m aware. The server does run shadow copies but this is at 7am and 12pm, backup is at 8pm. I’ve set up a scheduled task to stop the VSS service just before backups run but whatever is using it, restarts it.Any ideas about how to detect what process is using the VSS service?Tha

I migrate Redhat VM from vmware to Hyper-v using VBR and the redhat can’t boot and stuck in dracut. Anyone know how to fix this?  

I am currently running Veeam Backup & Replication (VBR) version 12.3.0 and encountering the error "Permission denied (public key)" when trying to add a component server running Ubuntu 22 using SSH keys.Upon reviewing the logs on the Ubuntu 22 component server, I repeatedly see the following error:"Unable to negotiate with 10.0.0.8 port 64513: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1 [preauth]."It appears the VBR backuo server is offering outdated or non-compliant algorithms, such as diffie-hellman-group1-sha1, hmac-sha1, and also requires the deprecated ssh-rsa for public key authentication.As a result, my SSH connection from the backup server (10.0.0.8) to the component server fails, and I see the "Permission denied (public key)" error in the VBR console.I prefer to use SSH keys for authentication, and the SSH configuration (sshd_config) on the component server includes the following settings:GSSAPI

Veeam newbie and first-time poster here (go easy on me!) … I am trying to attach an Ubuntu Linux 24.04 “minimal” server to a VBR13 test environment.  This server is only intended to provide backup storage for VBR. While attempting to add the host as a managed server, I get the following error: “Setting backup server certificate Error: Remote failed with message:  /opt/veeam/deployment/veeamdeploymentsvc: boost::filesystem::copy_file: Invalid cross-device link: "/tmp/VeeamUpload_20250328T170010Z/ServerCertificate", "/etc/veeam/certs/cert.p12"--tr:Failed to install server certificate” /tmp and / (where /opt and /etc reside) are separate logical volumes. Any ideas on how to troubleshoot this? VBR13 imported OVA (VMware), Console (Windows Server 2019), and Ubuntu server all on local LAN.  Managed credentials for Ubuntu added in VBR Console seem to work. Thanks in advance!

Since we added Linux Repositories to our Veeam Backup environment in my post from last week, why not add some Linux Proxies as well? I will show you how in this post. And trust me…this one will be far less painful. But adding Repositories wasn’t so bad, was it? 😏 System RequirementsThe first thing you need to do is check what OS's, hardware, and software are supported. Supported Linux OS's are exactly the same as with Repositories and are listed below:Linux Proxy RequirementsAs far as hardware goes, your server should have a minimum 2-core CPU, plus 1 core pe

Hello,I keep receiving the following error:07.09.2023 10:22:46 :: Error: The network is at full capacityAsynchronous request operation has failed.

Hello Veeam Community,I am reaching out with a concern regarding our Veeam version 12.1, as we are consistently receiving malware detection alerts on our VMs. The notifications specifically indicate:Potential malware activity detected: Too many files have had their names changed since the last backup; ensure they were not encrypted by ransomware. Potential malware activity detected: *.ttt (TeslaCrypt 3.0): 40 instances. Potential malware activity detected: *..txt: 2 instances.I have conducted thorough scans on both the VM and the backup, and no malicious activity was found. Could you please provide insights or guidance on whether this is a matter of concern, and if there are additional steps I should take to address this issue?Your assistance in resolving this matter is highly appreciated. Thank you in advance for your support.

Sorry for the simple question, that’s no doubt been asked and answered before…Today we have VCC for our off-site cloud backups, and the immutability is provided by the “Insider protection” which in short means we pay for the privilege but we do not need to worry about disk space consumption over and above our actual backups.For lower cost we’re considering object storage, probably Wasabi, and we’ll want immutability there also. The thing I need to be sure of, is the disk space required. I am not sure if the copy jobs would have a specific backup mode, but with incremental, if they’re immutable, you’re previously overwritten backups are kept for longer? Disk space could be double what you have before?Thanks in advance for any insight on real world disk space requirements. Today, 27TB approx. is our VCC repo and as I say, the immutable data is retained at a fixed additional cost so we don’t know the size of that.

We would like to upgrade the Veeam 12.3.1 but we could not find the Veeam one 12.3.1 Version .Could you please suggest us, If we upgrade VBR 12.3.1  then Veeam one will allow to monitor the jobs ?

I was installing the VBR Console on my PC, and when connecting to the backup server, there was a version mismatch that the Veeam User Guide (HelpCenter) spelt out correctly. Here is the guide on how to “Install Veeam Backup Console on a Jump Server for Secure Access”, discussing all the prerequisites, installation steps, limitations and workaround.I searched through the community but could not find any post discussing the upgrade process for the latest version of VBR. Therefore, I will be discussing these steps below.Two months ago, December 3, 2024 to be precise. Veeam launched Veeam Data Platform v12.3, introducing powerful enhancements that significantly strengthen data resilience.  This release introduces
