case: 07735344keyword:  Server 2025,  24h2,  upgrade ReFSA few days after upgrading to Server 2025 (in-place upgrade ...yeah yeah...i know but options were limited), the CPU started to peg on the VM which would also max out the CPU of the host.  The VM would be unreachable/unusable until after a cold restart. Ultimately, it looks like ReFS version was slowly being upgraded on our SAN due to the upgrade and it was incompatible with Veeam.  If I kept all veeam services off...no issues.  Once the services were on (even with all jobs disabled), the CPU would once again peg and the VM would hang.After weeks of troubleshooting, I had to cut my losses and reformat/reinstall using server 2022....blowing away all backups.  Importing saved backup config did bring the Veeam server back with all settings and I was able to slowly bring all my backups online (I had to do it slowly because we have backup copy jobs going over a wan which took days. CMadison

Whenever I'm involved in a project that includes a deduplication appliance or even a dedicated storage system, the hardware vendor typically recommends implementing replication at the hardware level.In these scenarios, I often suggest using software-based replication, orchestrated by Veeam.Which approach is truly more appropriate? Is there a best practice for this? Do both methods work effectively?My recommendation is always based on the ability to control data retention and expiration, as well as the use of GFS (Grandfather-Father-Son) policies.Should I continue to follow this line of thinking? Does using hardware-based replication affect this in any way? Is retention management compromised?

Hello,do you have hints, where could be the issue with VM backup job without AAP, on vSphere: [18.06.2025 23:20:05.172]    <01> [000E]   Error (3)    Task failed.[18.06.2025 23:20:05.172]    <01> [000E]   Error (3)    Cannot find layout information for disk: 2000 (System.Exception)[18.06.2025 23:20:05.172]    <01> [000E]   Error (3)       at Veeam.Backup.Core.SanPlugin.CViStorageIntegrationProxyBuilder.GetDiskLayoutExForDisk(CVm vm, CVirtualDisk virtualDisk)[18.06.2025 23:20:05.172]    <01> [000E]   Error (3)       at Veeam.Backup.Core.SanPlugin.CViStorageIntegrationProxyBuilder.GetVmDisksLunsInfo(CViVmContext viVmContext, VmEntry vmEntry)[18.06.2025 23:20:05.172]    <01> [000E]   Error (3)       at Veeam.Backup.Core.SanPlugin.CViStorageIntegrationProxyBuilder.BuildSanProxyForBOSS(CViVmContext viVmContext, CViProxyResourceDesc[] sourceProxyResourceDescs, CViBrtProxyResourceDesc targetProxysDesc, VmEntry vmEntry)[18.06.2025 23:20:05.172]    <01> [000E

Hi,(Version 12.3.2, install on Bare Metal server - Dell - Windows Server 2022)A few months ago, we changed our antivirus: previously TrendMicro, now Microsoft Defender for Business. Since this change, restoring VMs larger than 2 TB no longer works. When we uninstall Defender, it works.Our first reaction was to open a service request with Microsoft. Unfortunately, this has been dragging on for several weeks! Microsoft can't find where it's blocking us or why, despite a phenomenal number of exclusions (much more than Veeam recommends – article kb1999).Error message :Backup not opened Agent failed to process method {Mount.QueryVolumesOnMountedDevice}Do you have any idea what might be blocking the restoration of VMs larger than 2 TB? Thanks,

Hi,I am kinda new to Veeam Backup. We do have some remote linux hosts without any internal connection to our local infrastructure.Now, to not use the internet directly, I installed Netbird (just like Tailscale) and connected both, the Veeam Server and the Linux Host. That works, all good.Now when I add the Host as Managed Server, the initial SSH Connection works and the Netbird IP is being used but then everything else is trying the WAN IPs which, of course, is not wanted and also blocked. So the Setup never finishes. Does anyone know what I could do here?ThanksAndreas

Hi All,I look for confirmation if Veeam B&R supports backups of SQL Encrypted databases on a Always ON environment. This with standard backup (vmware agent less) and via a a job with the windows agent both with application awarness.Thanks,Benny

Hi Not sure if this is the right place I have tried R&D forums.I use Veeam for Windows free backing up endpoints to NAS drives.I have a clients endpoint that's has been running fine for a long time but now gets stuck at 40% and in the end fails with Application Failed. Its stuck in backing up the C driveI have tried all the obvious, updated to latest, reinstalled, deleted job and recreated the database but still seeing the issue. Run chkdsk not issues with diskAnyone seen this before?

Hi all,I’m getting the above error trying to install components on my managed physical server for Veeam 12.3 . I proceeded to manually mount the iso on that server and install the components myself, but still getting the error. I’ve checked and the Remote Procedure Call (RPC) windows service is running fine.Installed the Veeam VSS Hardware Snapshot provider and checked the Registry - all present.Checked logs for the transport service at ‘C:\ProgramData\Veeam\Backup\Svc.VeeamTransport.log’ on the managed server, and seems to connect fine with agent. Did a configuration backup and performed a clean install of the backup server as some other posts suggested but still getting the error.Not sure if a clean install should be done on the managed server as well.. but not sure what else to try either. Any suggestions will be greatly appreciated. Thanks.

Hello, Thanks,I did a fresh install of VBR on a new machine, using freshly downloaded, latest .iso i did a succesful agent backup of MACH94. Then I tried to agent backup SERVER02 and that failed. “5/28/2024 6:08:33 PM :: Error: The specified path is invalid.

Hi everyone,I'm facing an issue while restoring Jenkins data using Veeam. Specifically, when I try to restore the config-history folder (which contains Jenkins configuration history), the restore fails. However, if I attempt to restore a smaller subset of data, it completes successfully.Details: Veeam version: 12.3.2 Backup type: VM-level Error message/log snippet: a connection attempt failed because the connected party did not properly respond after a period time, or established connection failed because connected host has failed to respond Veeam Support - Case # 07775632Has anyone encountered this before? Could it be related to file size, permissions, or something else?Thanks in advance!

Hi, I was not able to make a comment on the NFR Thread - so I had to create a new. Im a VMUG member and have introduced Veeam to a number of customers and I’m running it in my homelab on NFR licenses. 20 VMs is a challenge as I have over 100 VMs but now I’m protecting the 20 most critical. Just recently i decided to use Veeam for my Fileshare as well as this would allow me to easilly create a cloud backup job (S3) as well as a tape job (I have an LTO-6 FC tape in the lab) However its not clear how Fileshare licenses is done, I assumed one Fileserver was one workload - but after I created one and copied 3TB or so of data I could no longer run any additional jobs. This was strange as my intention was to have a few fileserver backup jobs where secondary jobs would kick in - some fileshares would get an S3 copy, some would land on tape and so on. The license says (500G) and I have 6 instances, does this mean 3TB of data? Thanks.  

Dear all,I'm currently encountering an issue with one of our backup jobs affecting approximately seven virtual machines.

Hi allI was wondering if it is possible to create a backup job of a VM, without having access to the VM Host Server. I have installed Backup & Replication on the VM client itself, connected a backup repository, but when I try to create a backup job, it asks for the IP and admin credentials of the VM Host. Thanks for your help

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 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?
