I first of all installed Veeam v12.3 on an external drive then i uninstalled it. I then tried to install it on the hard drive of my PC, but this error popped up. I did some research and discovered it could be because of the last installation residues that could still be running in my PC. So i went on checking all the possible places where these residues could be (task anager, register,...) but still after trying to install it the same error pops up. So what can be the problem with this installation?  

Hello,I’ve just installed Veeam B&R and VeeamOne (both version 13) on one physical Windows Server 2025.Was it mistake? Because I cannot configure and start Veeam Intelligent Diagnostics.The reason (not confirmed yet) is Veeam Analytics service.Description here: Veeam Intelligent Diagnostics - Veeam ONE User GuideI need two instances of this service, in Server mode for VeeamOne and in Client mode for B&R.Or VID can work without Veeam Analytics service, because this is within ONE physical server?I hope, someone has solved this already...Best regards,Tom

Hello,When using VDC Calcultor for Azure VM workloads, for a snapshot size of ~64.4 TB there is an associated snapshot cost (~$3,297) with a Bronze policy (1 per day for 7 days), I am missing clarity on how this cost is applied over time.More specifically, could you please clarify:1. Is this snapshot cost:- calculated per month,- per year,- or is it a cumulative cost based on retention (number of snapshots × retention duration)?2. Does the displayed cost already account for the 7‑day snapshot retention, or is it the cost of a single snapshot instance? Thank you for your clarificationBR

Hi, I was using Veeam v12 on my server to backup my virtual machine on Windows Server. I got hacked with a Kraken v1.3 ransomware virus and all my files were encrypted. Most of the files on my backup drive also got encrypted, but the biggest and main backup of around 700GB seems to still have it's original extension. (the smaller files which i believe were incremental backups, are all encrypted) I setup a new server and installed Veeam v13. I tried to do a backup import of the main backup file, but then i receive an error:2025/12/10 10:14:39 Failed : Failed to import backup Error: Storage version [1390707963] is not supported for read-only access. Failed to open storage for read access.

Anyone can help me to resolve this issue.   

I try to connecting the SMB server to as VBO repository and always access denied, even i can write to the SMB folder using windows explorer.In this article KB2971: How to add SMB repository to Veeam Backup for Microsoft 365 i can see we must computer name authentication on the share permission,In my case the SMB server and VBO server is not joined to the domain, both of machines is standalone.Anyone here know how we can use the SMB fo repository?

Hello guys, I’m using the Calculator on a daily basis, and am pretty sure the calculation is wrong (or maybe I’m?? :D) when you consider Immutable GFS Backups to Object or local storage.If you backup Immutable the Calculator will ask for a immutability Period, this in fact does not matter when using GFS as always one Full Backup will be kept for the configured GFS Retention.Or at least as far as I’m aware.Heres my test:Lets say we have 16TB of source Data, this is the immutability with 14 days and gfs.​​​​​​ As far as I understood it, 16TB is round about the source capacity, of course we will shrink it a bit thanks to compression.Lets say a full backup will then be 10TB which seems surreal already. And lets now turn gfs off in the calculator.Now we only have 14 Dailies immutable but we are missing another 11 Full Backups as stated, GFS will always take full backups. Am i doing something wrong? Is the calculator not able to predict this scenario? 

It seems the FILE EXCLUSION tab is missing in Veeam Community edition even though the only thing it is supposed to be limited don is the number of workloads. When I go to the job, guest processing and edit, there is no choice to exclude files. What am I missing here? 

HI folks,We are increasingly deploying Hyper-V environments following recent changes in VMware’s pricing model. In my designs, I typically separate production and backup infrastructures into dedicated VLANs.However, when using an on-host configuration, applying this architecture means that traffic will inevitably pass through the firewall, which could lead to excessive load and negatively impact backup performance.The most straightforward approach today is to implement both Veeam and Hyper-V components within the same subnet to avoid any routing.  How are you currently handling this in your environment?

Hi Community, Is there a PowerShell command or script to create multiple backup policies in Veeam Backup & Replication? Thanks!

Hello Veeam Community,I have a question regarding cross-platform restore. If we have a backup of a VM running on VMware ESXi, can we restore that backup to a Microsoft Hyper-V environment using Veeam Backup & Replication?Both environments are supported by Veeam, but I want to confirm if this type of restore is possible and what the recommended approach would be (e.g., direct restore, conversion, or any limitations).Has anyone implemented this scenario successfully? Any best practices or considerations would be appreciated.Thank you!

We are facing an issue with VBR where the application is down and cannot connect to the backup server. The error message shown is: “No connection could be made because the target machine actively refused it 127.0.0.1. Make sure the backup server you are connecting with is 12.3.2 version.” Has anyone encountered this issue before? What steps or permanent solution can resolve this? Any guidance would be appreciated.    

Hello, according to the calculator S3 is not more space efficient with immutability and GFS than XFS/ReFS. This does not sound correct.Does anyone have realistic values comparing S3 to XFS/ReFS? Markus

Currently i already backup virtual machine under Azure Local / Azure HCI environment.Now i have plan to upgrade the Azure Local host and to mitigate if the upgrade failed i want to restore from the backup.So anyone know here how we can make backup for azure local host itself? Since the OS is using Azure Stack HCI

Hi everyone,I’m using the Veeam community edition to backup some data to WORM tapes (I have an HP Ultrium LTO-4 1840 tape drive with HP LTO-4 WORM tapes). Unfortunately, I’m getting the following error when the backup job starts: “There is an old MTF block on tape. Cannot write a new one” after which the job fails before backing up any data.  The WORM tapes are all brand new/sealed, so are completely blank and the write-protect toggle/switch on the tapes are all set to off. I created a WORM Media Pool and selected ‘Do not create, always continue using current media set’ for the Media Set.On first-time insertion, the tapes were inventoried and added to the WORM media pool (Veeam successfully recognizes the tapes as WORM capable) so all looks good.However I’ve tried 3 brand new tapes so far and they’ve all failed with the same error above, although the same backup job works perfectly on normal RW tapes, so I’m not sure if I need to do anything extra in Veeam to get WORM tapes working?I’v

There is an option for cross hypervisors VM creation in instant recovery, what would be the performance (any impact on the performance?), compatibility issues, and what would be the required tools (if any)?

Hi, This is a last resort post of sort as I can’t find any information on what is the expected scenario.On Solaris, our plugins were recently upgraded and pkginfo shows below with Version - 12.3.2.4165 $: pkginfo -l VeeamPluginforOracleRMAN PKGINST: VeeamPluginforOracleRMAN NAME: Veeam Plug-in for Oracle RMAN CATEGORY: application,system ARCH: SPARC VERSION: 12.3.2.4165 BASEDIR: /opt VENDOR: Veeam Software Group GmbH PSTAMP: 501cb4f0240920251001193914 INSTDATE: Dec 04 2025 14:01 STATUS: completely installed FILES: 8 installed pathnames 2 directories 5 executables 190948 blocks used (approx) In the RMAN log, it shows comment=API Version 2.0,MMS Version 12.3.0.54 Question is should the RMAN log be showing 12.3.2.4165 as well or it doesn’t matter or did we mess up somewhere during the upgrade and it is actually a failed upgrade regardless of pkginfo information? Checking /opt/veeam/VeeamPlugin

Hi all,we have a customer with an Openshift Cluster and a Netapp storage for volumes.The goal is to use a Veeam Hardened Repository for volume export, but the storage class is using a “ontap-nas” backend, and the block mode is not supported.Do I have to use a new storage class with “ontap-san” backend and reconfigure all applications or is there another way?Thank youMarco S.

I have many customers where we store data with GFS points on the backup copy page.For example, primary repo 14 days, secondary 30 days + 6 monthly. Now, this is not a problem in the Sizer for VMs.However, if I have NAS backups, only the days apply here, but the monthly backups are completely omitted because NAS does not support GFS. There should be a message in the Sizer or an automatic conversion of the workloads to days (6 months x 30 days = 180 days).Otherwise, if you are not careful, the entire sizing may be incorrect.

Why Redhat 8.6 is supported and Rocky Linux 8.6 no?

Hi Community, For those using the Google Cloud Platform (GCP) appliance integrated with Veeam to protect workloads such as VMware VMs, agent based backups, and native GCP backups, I have a question about performance tuning.My VBR server has 32 vCPUs and 64 GB RAM, and it acts as the Gateway Server for a Google Cloud Storage bucket. What is the best practice for setting the number of concurrent tasks for this configuration to achieve optimal performance without overloading the system?  

 Hi everyone,I wanted to raise a question regarding the upgrade process for Veeam Backup for AWS.From my understanding, performing major version upgrades currently requires installing the on-prem Veeam Backup & Replication  — even if only the trial version — just to run the upgrade wizard.This feels counter-intuitive and unnecessary for several reasons: Veeam Backup for AWS is a cloud-native solution, often used in environments that don’t run any on-prem VBR infrastructure. Requiring an on-prem installation introduces extra operational overhead: Deploying a Windows VM Installing and updating VBR Managing firewall rules and connectivity For customers who deliberately chose a fully cloud-based architecture, installing an on-prem VBR instance only for upgrade purposes breaks the expected simplicity of a SaaS-like product. The appliance already updates minor versions internally — so having major upgrades depend on VBR seems inconsistent. Is there a technical limitat

Hi teamPlease excuse my ignorance as I have not done this before and would like your advise.Current VEEAM implementation has AHV proxy configured to back up the environment.A new AHV clusters will be added. My initial uneducated thought assumed to re-use the existing proxy but I think that is actually not possible now. It seems the proxy configuration cannot be altered so I think it leaves me with no choice to create new one. No biggie.Also, I noticed that there is an embedded worker for the cluster configured in the proxy.In general, Would you suggest adding more workers to the new cluster? There are 3 nodesCheers

I hope you can help me with the following problem. When I perform a sure backup (Backup verification mode: Backup content verification  and content scan only), I get the following message in the log: Error: Failed to call RPC function 'FcCheckFilesystemIsAccessible': The volume does not contain a recognized file system. Please make sure that all required file system drives are loaded and that the volume is still corrupted. The email notification I receive indicates that the verification was successful. My question is why I'm getting this warning and how can I resolve it? Here are some specifications of our server: Veeam Backup & Replication Build 12.3.2.4156 Backup server runs on a Hyper-v  Hyper-v: Windows Server 2025 24H2 Build 26100.7171Bare metal: Windows Server 2022 21H2 Build 20348.4405 Hopefully you can help me with this. Best regards,  Jordy
