Hi community, We recently performed a failover of vm100 to maintain server operations during a scheduled upgrade. The replica VM is currently running as expected.However, we are now unable to initiate a failback to the production site. The process fails due to an invalid disk configuration on the running replica vm100. When attempting to edit the VM settings to remove the problematic disk, vSphere returns the following error:"Invalid configuration for device '0'"Scsi 0.5 mapped to Hard disk 6 in vm100_replica.Supposedly, in original VM, there should be no Hard Disk 6. But the replica somehow attached the Hard disk 6 Does deleting the oldest VM snapshot will help anything. Is there a way to delete this Hard Disc 6?  Thanks! 

Dear,I have an certification VMCE 2023 I would like is this certification is expired or notCan I upgrade my VMCE when VBR 13 is available Best Reagrds 

Hi,When using hardened linux repository, veeam services add some temporary rules to UFW, allowing traffic between backup components:[ 4] 6162/tcp ALLOW IN Anywhere # Veeam transport rule[ 5] 2500/tcp ALLOW IN Anywhere # Veeam rule eeba7ea1-3cd4-4251-8800-9fa455f03ece[ 6] 2501/tcp ALLOW IN Anywhere # Veeam rule eeba7ea1-3cd4-4251-8800-9fa455f03ece[ 7] 2507/tcp ALLOW IN Anywhere # Veeam rule eeba7ea1-3cd4-4251-8800-9fa455f03ece Is there any way to limit source IPs ?Is there any config file to insert source IPs, so that veeam service can use those IP for creating UFW rules?

If we completed the VMCE on 2023 then if we want to take VMCE 2025 for example, then the training is mandatory or we can go directly by taking the exam?

I have some question about VDC for M365 below.If I have 500 license, is there any tolerance how much the user can excedeed than owned license? 1 license will be counted if the user have mailbox? If we have 200 user have mailbox and 500 sharepoint site how we can understand how much license will be consumed?

Today i googling that VBR can connect to the VDC for backup repository. Anyone ever using this scenario? And if VBR conencted to VDC is there any additional cost?

Recovered VMs not powering up in Datalab test due to unable to access virtual hard disks.Have a couple of large VMs with multiple disks (60 and 90 TBs and 10 disks on each VM) that will not power up due to the error above. We are using storage failover and we have daily replication of the production volumes to our DR volumes. Replication status on our Storage device show that replication is successful but vsphere shows host incompatibility/permission issue accessing the disks.I don’t think that this is either a host or permission issue since the other virtual disks for the same VMs can be seen in vCenter. There are other VMs in the Orchestration and these are the only 2 servers that would not come up. Below is a screenshot from vCenter.  

hello, thanks, i ran a manual re-scan of the backup repositories.why are some repositories have `skipped` ? some of the .vbm files are damaged? i know VBAR has this scary quirk where for agent backups, even if i have the .vbk, i cannot restore without the .vbmplease advise, thanks, david          Starting backup repositories synchronization         Enumerating repositories         Found 10 repositories         Processing backup repositories         br_theserver03_theen10_cdrive_old: Synchronizing         br_theserver03_theen10_ddata: skipped 1         br_theserver03_theen10_cdrive: skipped 1         br_hetz05: Synchronizing         br_theserver03_theen10_falconer_02: skipped 2         br_thevserver03_Virtual-Machine agent_vserver03_01: skipped 1         br_theserver03_theen10_cdata: No backups found         Default Backup Repository: skipped 1         br_theserver03_ts-ubuntu01: failed 1         br_theserver03_theen10_falconer: failed 1Warning    Failed to import backup path V:|br_thev

We are building a “green zone” where basic infrastructure systems including a hot standby backup environment should be running. This env is completely separated from current pro environment. This env will have no AD at the beginning. VBR is using a dedicated SQL server.Our current VBR server is running in prod domain (ideas to move it and all Veeam systems to a dedicated domain exist for a long time but were never implemented. The idea to remove the systems from domain and use Workgroup also exist).The very simple idea is currently to have a second VBR VM instance running there + some other Veeam components + a empty Linux repo and start downloading/stage backups from immutable Cloud Object Storage to a local Linux repo in this green zone ASAP to have everything local again and ready to restore. VBR server and all Veeam systems will run in Workgroup mode then. Ideally we would at least have the Veeam config backup available + all needed credentials an keys.Would this be possible out of

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

Hello, I have added a NUtanix PE in VEEAM Backup but when I Create a backup jon and under backup→ advance setting I cannot see Incremental Backup. What might be the issue. I want to create below schedule. What is by default method in VEEAM? Is it incremental or Full Backup, or a Mix? o    Create weekly full backupo    Create daily incrementalo    Set the schedule for the backups at 10 AM every every morning to run daily incremental, weekly full at Friday 10 AM Morning.o    Set retention date to 2 weeks for weekly full, 2 weeks for daily incrementials and 1 week for deduplication.  

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

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. Error: in [VctSetCtStorePath] at step [3] Agent failed to process method {VeeamVolumeCt.SetUserStorePath}“  

The storage system is in the SynchronizationFailed state Failed to synchronize storage data: An item with the same key has already been added. Key: 4422-afbb-aass-xdxd….. I would like to try removing and adding the affected storage but not really sure to what extent this would affect the Orchestration Plans. Or could this just be a DB issue?

Hi all,We are currently facing an issue during the installation of CDP (Continuous Data Protection) in our vSphere 8.0.3 environment. Setup: Hosts are updated exclusively using offline ISO images ISO files are internally validated and approved via change control Online depots are completely disabled vLCM is configured with only our custom HPE ISO (VMware-ESXi-8.0.3-24674464-HPE-803.0.0.12.1.0.11-apr2025.iso) vCenter version: 8.0.3 Hosts affected: esxi03.cloud.local (and others) Problem:When attempting to install CDP, remediation fails with the following error: Host 'esxi03.cloud.local' was not processed, the reason: 'Failed to validate the checksum of VIB 'http://hostupdate.vmware.com/software/VUM/PRODUCTION/addon-main/addon/HPE/vib20/qfle3/QLC_bootbank_qfle3_1.4.51.0-1OEM.700.1.0.15843807.vib', because the computed checksum differs from the expected one stored in metadata. Make sure the specified VIB is NOT corrupted and the expected checksum stored in metadata is correct.'

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?

Dobrý deň.Do siete budeme mať pripojené dva nove SMB zdielane disky, každy o veľkosti cez 20 TB.Vedeli by ste poradiť s vytvorením/nastavením backupu? Diskusia okolo toho by sa mi hodila :) 

We back up to disk then duplicate to tape for offsite storage. Not quite ready for cloud backups yet. I am wondering if anyone has any experience with Quantum LTO-9 tape drives with Veeam backup. I have quotes for two models. TD-L92BN-AR and TD-L93CN-AR. Thanks.

I have an infrastructure operating on a Nutanix Cluster and Prism Element, and I have integrated it with VEEAM Backup. I possess a socket-based license for VEEAM, and the cluster appears online in VEEAM. There are about 15 VMs in my infra, and I have set up a job to back up all the VMs which are within the cluster, I start the job and observed that it is not utilizing the socket license. Instead, it's recognizing an instance-based approach and only backing up a few VMs, with the rest displaying a license overutilization error. Can any one let me know How Nutanix works with VEEAM, is it a socket based license or instance based license only.

Hi everyone, how are you? I have a customer who has multiple M375 tenants.For example:Main tenant - 200 users Tenant Egge Unit 1 - 50 users Tenant Edge Unit 2 - 50 users We understand the limitations- It's not possible to restore between tenants- It's not possible to distribute licenses between tenants However, we can manage tenants from the same console, as mentioned by​ @MicoolPaul  in the post below. The customer's big question is: If I delete a tenant (this is common in edge units), will I lose all the licenses associated with that tenant? I'm thinking about the possibility: Or can we open a case with Veeam to "unlink" these licenses from the tenant so I can use them in another tenant? Thanks in advance!  

Hi VRO heroes!…how do you work within a Recovery Plan when it comes to a parallel processing, for example 5 VMs simultaneously?  For example: in this specific plan (built on based with Tags), there are some Domain Controllers in it. Within a DataLab Plan i can add the option for Prepare DC for DataLab (preparing services, exiting DSRM and so on). Within a Recovery Plan, this is not available. But in the case of a Desaster, and these DCs within the Recovery Plan are the only available DCs - they has to be started first.With a parallel processing and no available option for a Pause-Step, other VMs will be booted, even the Domain Service are not yet available.For sure, i can start those DCs within a separate Recovery Plan first or a better solution: have a DC also running and available at the DR-Site…What do you think about it, or how do you handle this?  thanks and best, Markus

Hello,I have situation were I have to export fully Entra ID backup from Veeam, how to do that?There are hypothetical examples with powershell, but I have to export the full backup for authorities. # Hypothetical example$session = Open-VEXEntraIDSession -BackupId "your-backup-id"Export-VEXEntraObject -Session $session -ObjectType "User" -TargetFolder "C:\Exports"
