I'm experimenting with the VHR 2.0.09 ISO. It works perfectly for me. I'm using a virtual machine for VHR where I have two disks added, one for the OS and one for the repository. I'm trying to extend the repository. What would be the recommended steps to extend the disk, or is it not possible?

Scenario, a customer has a complex environment where their DC doesn’t have groups for servers, Laptops, Different users in different regions. Customer want to backup servers and endpoint but the laptop backup has different requirement. Let’s say Executive backup must backup the entire PC and other users you select a specific folder.  If you deploy backup protection group using CSV files, there is a lot of manual requirements if changes happen to that environment.  The question is how to use AD to create separate requirement even thou the DC is complex.

OS is Linux Mint Mate 22.  Been running VAL v.6 successfully for some time, now looking to update to v.13.  File downloaded, only option seems to be .iso for which I use Balena Etcher.  BE says, problem with this file, and cannot continue.  Ran the download three times, BE tells me the same thing with each of the downloaded files.Previous Veeam downloads were .deb files, used for ubuntu/debian systems.  Could be there isn’t or won’t be such for v.13.  Anyone know whether v.12 is available?

Hello Team,I am using Veeam Agent / Veeam Backup and Replication for backup storage on a NAS.I noticed that in my backup repository folder, Veeam creates:.VBK full backup files multiple .VIB incremental backup files .VBM metadata filesMy question is:Why are there multiple .VBK files stored in the same backup folder?Are these incremental restore points expected behavior?Also:Will Veeam automatically delete old .VBK and .VIB files according to the retention policy? Is it safe to manually delete multiple or older .VBK files from the repository folder if storage becomes low? How does Veeam manage the backup chain cleanup process?I want to better understand how Veeam handles incremental backup retention and storage management.Thank you. 

Hello, On new V13 VSA installation, I would like to backup some VMs (inside domain) with AAIP enabled.When I try it as I did with V12, it doesn’t work. My VSA is not in a domain.I saw for authentication only Kerberos or certificates can be used (from Veeam deployment kit) because NTLM is removed.Does that mean I need to add my VBR server to the production domain if I don’t want to use Veeam deployment kit on all my Windows VMs ?  I don’t find a way for my backup to work with AAIP enabled while I’m using domain\user account with correct privileges.I have this error : 29/05/2026 14:33:16 Failed : Failed to connect via Administrative share.Host: [COMPUTER.domain.com].

We are facing an issue where SentinelOne is blocking our Veeam Mount Server, even when the operation is happening on the same server (VBR Windows).These errors occurred after attempting a File Level Restore (FLR):   We tested using Interoperability mode, but the error persisted. We then tested using Performance mode, and the restore was successfully mounted.  Has anyone experienced this behavior before or found a workaround?

How can I get VAW to power the computer on (from shutdown, not from sleep or hibernate)?I set the backup to turn the system on at 01:30 and run the backup, but it actually started when I switched the computer on later in the morning.Is there some Windows registry, or BIOS setting that is needed?Thanks, David 

Hi ALL,I am running VBR11 and VBAz 4.0, recently all my AzureVM backup started failing. I still have over 3months of license validity.I can no longer connect to the VBA from my VBR console only can access from the browser.We are getting the following error; "Client secret has expired. Use a valid client secret or renew the application on the Service Account Type tab.This was done however the issue still persists.My Infra is still running older systems so upgrade was not an option hence no support available.Any thoughts?

Hi All, I really hope someone can help! I have Veeam Backup for Microsoft 365 which is now running in community edition. I had two backup jobs, S3 to Wasabi and they have been deleted. I can see the repositories contain large amounts of data but when I attempt to restore files utilising the Veeam M365 console it only shows one restore point date.Previous backup jobs (excluding the deleted backup jobs) I had created and ran a backup copy from the existing backup job from Wasabi to a newly created Azure storage account and this appears to have worked. As I no longer have the backup jobs, what are my options of being able to restore these backups once I no longer have access to Wasabi? Thank you,Scott

Hello everyone,I need some help with an issue and hope I won’t have to contact support.  I’m seeing several failures on a file backup with the following error message:Failed to perform repair backup Error: Agent: Failed to process method {NasMaster.TransformMeta}: The process cannot access the file because it is being used by another process.Error: Agent: Failed to process method {NasMaster.TransformMeta}: The process cannot access the file because it is being used by another process.Processing finished with errors  I checked the logs, and the only thing that stands out are warnings like:Masks are not applicable for the server pathSo I understand that my exclusions cannot be taken into account. I can’t seem to find a solution; I ran a Backup health check which returned the error:Failed to perform repairing backup Error: Agent: Failed to process method {NasMaster.TransformMeta}: The process cannot access the file because it is being used by another process. I don’t understand how to ide

Hello!I look through logs, and see this texttransport mode: [hotadd], max sectors to read/write: [8192], async I/O: [unsupported]The backup operation ends successfully, but why could possibly async I/O be unsupported for hotadd? I've changed VBR VM (it's a Default Proxy) SCSI Controller type to VMware Paravirtual and it didn't help and sincerely I'm out of options to guess. Can you suggest me a direction to dig?

Hi,we have Veeam Backup and Replication v13, Community Edition, Build 2067 on Microsoft Windows Server 2019 with Hyper-V.When I try to add a Veeam Data Cloud Vault from the Austria East Region I get the following error:The error occurs during authorization of the backup server after I login using Microsoft, including MFA and after I answer the question if I want to stay signed in (Yes or No has the same effect).If I add the same VDCV Repo on another installation of Veeam (different customer, paid version) it works.I installed the Veeam Console on the only VM of the server and I got the same error.AI suggested to check the version of a specific DLL, which is 2067.I installed a trial license, same error.I disabled all security filtering on the firewall temporarily and checked the logs.Any ideas, how this can be fixed? Thanks a lot for your help!Thomas

Buonasera (o notte 😄) a tutti, vorrei avere consigli su che strategia adottare. Voglio backuppare tutto il mio sistema, circa 550GB, nel seguente modo: ogni mese avere un full backup, ed ogni tot fare un backup incrementale (max 3 per mese, lo faccio manualmente quando capita). Ogni fine mese sposterei il backup su un HDD esterno. Purtroppo non ho molto storage a disposizione, quindi i primi giorni del mese successivo, vorrei che il vecchio full + tutti gli incrementali, che ho già passato sul disco, vengano “cancellati” e venga creato un nuovo active con cui seguirò tutta la procedura. Qui sorge la prima domanda: nelle opzioni di Veeam vedo solo riferimenti al numero di giorni e non al numero di restore points. Posso inserire 4 come valore, per contenere il full backup + i tre incrementali oppure è sbagliato? E se per caso facessi 5 backup in tutto, la policy non rischierebbe di cancellare anche il full iniziale oppure essendo questo appunto un full non verrebbe intaccato?Come second

I am trying to add a Microsoft Azure Stack Hub account to Veeam Backup & Replication v13, but I do not see any option to add Azure Stack Hub under Cloud Infrastructure or Add Server.I also could not find any official Veeam v13 documentation related to Azure Stack Hub integration or support.Has anyone successfully configured Azure Stack Hub with Veeam v13?Is Azure Stack Hub still supported in version 13, or has the feature been removed/changed?Any guidance or documentation would be appreciated.

Hi everyone, has anyone tried using OMV 8 (Debian 13.4) as a Linux backup repository for Veeam VBR v13? I checked the official documentation for VBR v13 compatibility, but it currently only lists support from 11.0 up to 13.1. Would I be safe to proceed with the OMV 7 to 8 upgrade?
