Some of my virtual Linux Server are unabel to backup. The job ends with the following error: Error: The request could not be performed because of an I/O device error.Asynchronous request operation has failed.

I’m trying to do my first backup with the Windows Agent, but it fails several hours in.After the first failure, I ran chkdsk on the target, and no errors were found; the second attempt failed in the same way. I have 2 drives in the system: It recorded success for the first one.I tried to open a case for this, but no luck so far.7/6/2025 12:14:22 AM :: Error: Shared memory connection was closed. Failed to upload disk. Skipped arguments: [EmulatedDiskSpec>]; Agent failed to process method {DataTransfer.SyncDisk}. Exception from server: The requested operation could not be completed due to a file system limitation Failed to write data to the file [E:\VeeamBackup\greatful\Job greatful\Job greatful2025-07-05T172307.vbk].Failed to download disk '251db751-6938-460c-8b6d-c34dc909537e'  7/6/2025 10:08:23 PM :: Error: Shared memory connection was closed.

Hi all,We have recently moved from VMWare to Hyper-V.We use Veeam B&R V12 and have encrypted offsite backups going to a remote backups repository via a site-to-site VPN connection to a third party. On VMWare, we used VMs as backups proxies and included only those VM addresses in the site to site VPN.When we moved to Hyper-V, because of the on-host backups proxy architecture, we needed to add the Hyper-V host IPs into the VPN profile.  On any given day, I’m happy that the remote team follow best practice in terms of security but I’m not willing to expect that to always be the case.  I’m really not comfortable having our host IPs being directly accessible from a third party location, when they have control over the remote IP scheme.Is there any way to introduce a VM as a backups proxy as per the VMWare architecture to remove the Hyper-V host from the VPN?If not, is there any reason why I can’t just block all inbound access from the third party IPs?  I would expect that all activity i

Hello,We currently have backup jobs configured in Veeam Backup for Microsoft 365 (VBM365) with a retention period of 6 months.We would like to stop some of these backup jobs, while retaining the existing backup data for a period of one year.We have a few questions: If we change the retention policy of a job to one year and run a final backup, will the new retention period be applied to the previously backed-up data? If we disable the job after modifying the retention, will the new retention still be applied to the existing backups? Finally, could you please advise on the best way to ensure that our existing data is retained for one year, even after the backup jobs are stopped?Thank you in advance for your feedback.

Installed Windows agent on my new Windows 11 machine, then went into “Create Recovery Media”.I could not complete it without giving Veeam precise location access, which seems really...odd.And it does not appear that it actually did access my location.Veeam Agent for Microsoft Windows 6.3.2.1205 - Free Edition

Hi Veeam team,I recently upgraded our Veeam Backup & Replication server to version 12.3.2.3617 on a Hyper-V host (not ideal, I know). The upgrade failed. Upon reviewing, the VBR has been upgraded, but the console won't connect. An attempt to upgrade console will end up in the following error “Unable to update the backup console because the following products are installed on this server: Veeam Backup and Replication Server”Checking the logs, it says:[04.07.2025 05:09:16][INFO] Installing Veeam Backup & Replication Console[04.07.2025 05:10:52][ERROR] Fatal error during installation. Steps I’ve already tried: Rebooted the Hyper-V host Force-stopped all Veeam services and processes Tried installing console via both GUI and from ISO Verified version mismatch (Console still on 12.3.1.1139, Server is 12.3.2.3617) Confirmed no backup jobs are running Still stuck in a loop where the console can’t connect or be upgraded, even after a clean reboot. Would really appreciate guidanc

Hello All,I learned to install VBR on a physical standalone machine on premises without being a member of a domain which totally makes sense. However is it okay to install the VBR components of VBR on a VM in a Proxmox environment, but have the repository on a separate standalone computer. So the backup are not stored in the same environments as the production data. What are the Pros and Cons?Thanks!  

Hi,I wonder how I could relocate the PostgreSQL database simply to another drive.The installation performed the default installation on the Windows C-drive.Because we also create an SMB file share backup of a large share, the database grows quickly and we need to enlarge the C-drive often.So we would like to relocate from the default location to simply another drive (not another computer).Is this also with the configuration backup migrate method?Is there something we need to do before?Can we use the psql tool to do this easier?regardsSteven

Hi(Veeam version 12.2.0.334)I want to move the PostGreSQL database from drive C to drive D.Following my steps, the PostgreSQL service starts correctly. However, the Veeam service doesn't start.I haven't found a clear procedure for this.

Hello,I understand that Veeam supports immutability on Dell Data Domain deduplication storage appliances.Here is my current setup:Backup job targeting a ReFS repositoryBackup copy job to a primary Data Domain with immutability enabledMTree replication to a secondary Data Domain not managed by VeeamMy question is: will the data replicated to the secondary Data Domain also be immutable?The Data Domain OS version is 8.3.Thank you in advance for your insights.

Hi teamI need to update the AWS user in Veeam Backup and Restore v12 for a scale out repository Archive to AWS Glacier - however we no longer have access to create an “Archive Applicance” due to new security restrictions in our AWS environments.We only need to restore from this Glacier S3 archive - we are no longer writing to it.Is there a way to update the SOBR account credentials without using the wizard which forces the “Archive Appliance” setup?I think it may be failing on that step when I try to finish the wizard.ThanksAaron

We have an existing Veeam environment as a service provider and using Cloud Connect.  With this we currently host cloud backups and replication for tenants, which works fine.  We also have VMware vCloud Director integrated. We are just now implementing CDP into this same environment.  When CDP is installed into the environment, Veeam creates a new storage policy in vSphere named “Veeam CDP Replication”.  This storage policy has a requirement defined to “enable host based rules”, and the single rule that is enabled is “Replication” and Provider veecdp, which is the I/O filter name. For reasons I cannot work out as of yet, this storage policy will only see one of our datastores as compatible, and this datastore happens to be the local direct attached storage of one of the ESXi hosts in the cluster, not storage on both hosts.  All other datastores show as incompatible.  Our other datastores that I would like to use are NFS volumes on Linux hosts.  I have set this up in a lab and demo envi

Hi all,I have a request to back up several Microsoft Azure Virtual Machines hosting SQL Server and Oracle databases using Veeam Backup for Microsoft Azure (VBAz).I’m looking for a clear summary of what can and can’t be done when using VBAz for these workloads, ideally in a concise, bullet-point format.Specifically:Can application-aware processing fully protect SQL and Oracle databases?Is transaction log backup and point-in-time restore supported for SQL?Can individual databases be restored without restoring the entire VM?Are there scenarios where Veeam Agent for Windows or Linux is required instead?Any guidance, best practices, or references would be greatly appreciated.Thanks in advance!

Hi, I’d like to know if there is anything on Veeam’s roadmap regarding official support or a new plugin for direct integration with Huawei's hypervisor (FusionSphere) and storage solutions like OceanStor — especially considering the improvements in Veeam v12 and the use of the Universal Storage API?

Hello,since veeam 12.1 version there is a conflict to use VAL for backup OS of backup repository due certificate of transport service. You can use transport service for repository purpose or use it for backup of root disk.Do you use some solution related to Veeam how to backup OS of physical repositories?For example with an issue after patching how to recover it. I have use script to install redhat from scratch from cobbler, but if someone has better solution, i will be happy to share it 

Hi All,Can Veeam B&R and Veeam Cloud Connect servers access the same Repository?I am a service provider, and offer Cloud Backup Repositories to customers. To test backups for customers, i used to make a copy of the backup files to another drive on the server, import it on the Cloud Connect server, instant recover the VM, login via console and check, then stop publishing, remove from configuration and delete the copy of the files.Now i see the “import” option is grayed out.So i want to know if it is possible:to add the Repository to my Veeam B&R server, Import the backup of the VM i want to test, Test instant recovery, then remove from configuration DB on Veeam B&R only (not delete) remove the repository from the Veeam B&R server.As this been done by anyone, is there another way to test, would this cause any problems?RegardsNolzzz

Hi, We keep getting this error intermittently, approximately once a week, then 5 or 6 successful backups. Any suggestions?

Hello friends,Currently running veeam agent v6.1.2.134 on a Win 11 machine.Have a full back up running every 3 months with incremental backups about every two days. Backups run to a network share hosted on a centos box.My issue: about every 5 days the back up fails and my computer freezes. It won’t kick the monitor, keyboard or mouse back on and I end up having to restart the computer by holding down the power button. I’m pretty sure it’s Veeam because it wasn’t happening before veeam and every time this happens veeam’s backup has failed. The backups will run fine the other times. There is no rhyme or day pattern I can tell of this happening since it’s every 5 days that it happens. So the last 3 failures occured on Fri 6/7; Wed 6/12; Mon 6/17. In between those I have successful backups and the 6/19 backup last night ran fine.Any thoughts? I’m a bit stumped. Happy to share the log file.

Hi, looking at the optimal veeam config for a veeam hardened repo with a storage platform that provides data reduction capabilities.From a repo perspective, “decompress backup file data blocks before storing” should be set. As well as “use per-machine backup file”aside from that, in the jobs, should I leave dedup and compress as OFF / dedup friendly?I was thinking that the job should avoid the extra overhead to dedup and compress the backup files as when it gets to storage it will decompress anyway.thanks in advance for the comments

After upgrading to v 12.3.2.3617, I have found a default setting which breaks certain elements of VBR and VCC.When creating an object storage repository, Automatic bucket creation enabled is the default!Step 4. Specify Object Storage Settings - User Guide for VMware vSphereLeaving this option on creates issues when using this repository for the following backups.Veeam Cloud Connect EntraIDConfiguring Log and Cache Repositories - User Guide for Microsoft Entra ID Unstructured data backup The problem is that going back and unchecking this option does not actual disable it. In addition, removing the repository and re-adding it with the option disabled also does not disable it. The repository needs to be created the first time with this option disabled. This is a major issue if one is unaware of the consequences of this option and just click “Next” through it or if repositories are being created with a script and this option is not disabled. If the repository is created with that option di
