Hi Community,Recently i install Veeam Agent on Windows Server 2008 R2 via VBR 12 Inventory and got an error  Failed to Verify C:\Windows\Veeam\Backup\Upload\VeeamDeploymentDll.dll Signature I found this page https://www.veeam.com/kb4677 and explain 2 possible causesAntivirus Block → Root and Intermediate CA is missingTo confim the issue we look at C:\ProgramData\Veeam\Backup\Svc.VeeamInstaller.log and gotFailed to verify file using the Authenticode provider. Verification status: A certificate chain could not be built to a trusted root authority. (-2146762486), last error: A certificate chain could not be built to a trusted root authority. All are pointing to Certificate Issue, so i install all CA listed on Veeam here https://helpcenter.veeam.com/docs/backup/vsphere/trusted_root_certificates.html?ver=120.After installing all CA still got same issue here. Are i missing something here? Any insight would be appreciated!

Two things:GCP” Same inputs for Simple Calc and Scenario builder. Simple told me to use e2-standard-8, SB told me to use e2-highmem-2. REally different. Worker requirements - neither calculator provided any information on worker requirements. Is this something planned for, or it is too difficult?

Hello everyone!Veeam 12.3.2.3617, Community Edition, Workstation Backup by veeam agentI’m having an issue with one of my home PCs. When I try to back it up, an error appears.29.09.2025 21:31:17 :: Error: Unable to resend traffic block '15863' because traffic history doesn't contain this block. History low block id '15869'.Failed to upload disk.

What could be causing this behavior?I tried replacing the target HDD — it didn’t help; the error can also appear when backing up the SSD (the drive’s health is normal, no errors).I tried different backup types (volume, file-level, entire PC) —

Hi All, I have a VBR 12.3.2 server running in AWS as an EC2 instance.  Use Windows agent on other EC2s to back them up to an S3 scale-out repository.  The backups work as expected.  I am able to do file level restores with no problems.  When I try to do a restore to EC2 (create a new EC2) I get the following error “Unable to import the instance from an encrypted volume snapshot” when I click Next on the Reason screen.  I do have it set up to use a helper appliance.  Do you have any thoughts on how to get this working?  The volumes of EC2 that are backed up are encrypted with an AWS-managed key (aws/ebs).  But shouldn’t it be pulling from S3 for the restore? Thanks for any help you can provide.Scott

Query related a IAM user and IAM role:  Suppose if any customer has a Multiple AWS Accounts  with Control Tower Environment AWS setup, approx. 50+ account and want to take a backup of instance and DB backup using veeam backup for aws appliance,  is it possible using single IAM user and single IAM role to take backup of all workload of this separate account .  Require a IAM role permissions for Control Tower Environment AWS setup, In veeam documentation it is not available.

Hi, I created “Backup Copy” and somehow is working if the Object Type is “Agents For Window Job” but not on “Repository”. Is there something I missed out ?   

Hi,A newbie here with using Veeam for Oracle RMAN backups.I am trying to understand/visualize whether the RMAN retention and Veeam Immutability are independent of each other or are they related in some way.We run our backups on the Oracle DB server using shell scripts and cron and using a RMAN catalog.We have set  CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 35 days.We do RMAN delete obsolete as well.The Veeam Immutability is 7 days.Does Veeam delete the backup files if they are 7 days old or does it delete the files if RMAN fails to delete them after 35 days? Or does Veeam do nothing unless we uses the force-delete?Kinda hoping someone has a presentation of some sort to show how this works. Have read thru the documentation and can’t find any that explains this. Or maybe it is explained more clearly/visually in any Veeam documentation and I just can’t find it.Any reply will be much appreciated. Thanks in advice. 

Hello Community!  I am new to Veeam (last used 7 years ago, so might as well be new). Here is my current setup:  I have two Mini PC’s running Proxmox as the “Compute”.They are connected over 10GB  to a different server running TrueNAS, via iSCSI.So the VM “Data” does not actually reside on the Proxmox machine, it just acts as the compute side. Now, I have installed Veeam on a Barebones Windows machine.  I configured the Veeam software to connect to the Proxmox servers (success) and it installed the proxy’s.First backup tested was successful, but the others failed.They show “succeeded” but with “Warnings” and no actual data has been backed up.“disk scsi0 has been skipped due to unsupported storage type” I find this odd since the storage type on the successful backup is the same as the other VM’s I am running, (Three Ubuntu VM’s & Home Assistant OS). Any insight would be appreciated!

I backup my home network.   I am using VEEAM 11.   What is the newest version to support Windows 10 or 11.   I doubt my two ISPs will allow Windows Server platform at my home.   Last time, I tried a Server OS to study at home with, my ISP shut down my internet until I turned off the server.   I want to install the VEEAM Backup CE Server on Windows 10 or 11.  

I’m testing several On-Prem S3 Object Backups ( Backing up Object Storage in 12.1) no matter which of the 4 systems I try I get the attached error. All of the systems have “buckets” that Veeam 12.1 has written to, and they have data in them, and are set as repo’s in VBR that I am using for this test. Suggestions? Error is attached - I get it on all of them. 

I am having trouble accessing the remaining 3 workstations I don't know where they are I only have 4 workstations here. I am here at the VBR.

I installed the Veeam 12.3.2.3617 on a virtual Windows Server 2025 and this has been a very bad experience.  I started to migrate the repository data to the new server, but it has become very unusable.  Now when I look up the issues on the web with Veeam, other people seem to have similar issues when using server 2025 with the repository on a ReFS file system.  At this point, everything is in limbo, meaning that the server randomly hangs when Veeam runs.  30% of the repository has been moved, but I can’t seem to do anything with the server.  Every time we try to access Veeam repository it just hangs.Does anyone have any suggestions other than scrapping the Veeam backup installation completely?thanksMatt

I have VBR installed in Site-B to backup VM under hyper-v and vmware in Site-A.Connection from Site-B to Site-A using ipsec vpn site to site with 2 internet link for redundant.The VPN have same policy for both connections. When the link use primary link then the VBR can backup the VM but if the primary link and connection switched to the backup link then i got error only for Vmware when using backup proxy.I try to ping from the backup proxy in Site-A then the proxy is able to reach HS-W2019.This error mean the backup proxy is not able to connect to the HS-W2K19 on port 2503? Error: Failed to connect to the endpoint [HS-W2K19:2503]. A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 

I am trying to get a Red Hat cluster added to my virtual infrastructure. After inputting all the information including the credentials I click apply. After 30 seconds I get a popup stating: “A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.” I checked that the logs and couldn't find anything that stood out except the previously written statement. I am running RHEL 9 and port 22 is open since I am able to SSH into the server from my Backup & Replication 12 host on MS Server 2022. Has anyone run into this issue or can recommend a course of action. I have input my credentials with the IP and without (Ex. first.last@192.168.1.1).

Hi All, Is anyone able to provide some more information on the ‘Job Name Mask’ in the VeeamOne disabled job alarm? I can’t find any information in the help pages.It obviously behaves like an inclusion mask, and I assume it accepts * and ? characters, but does it also support regex?I’m trying to specifically remove a couple of backup jobs from the alarm. Thanks.  

Hi Community,Does anyone knows if the calculator is under maintenance for CPD replication?I’m getting the error below. 

Hi, I have a protection group of 8 windows machines.  The machines were added to the protection group using their host names.  The machines get their ip from a DHCP server.  I see that one of the machines, originally with ip 192.168.1.151, is not 192.168.1.155 and is not being backed up.  Is there a way to update the protection group for the new ip?  Unfortunately, I cannot revert back to the original ip because that ip is now being used by another machine (that’s not part of the protection group).

once i try to install VeeamBackup&Replication the setup refuse to complete it just once started it gives  that The error "unknown exception occurred vmaGetpropertiesFromRegistry"and close the setup and refuse to continue i am sure that happes related to uncorrect uninstalled veeam application is that mean i look for another application ?

Hallo zusammen,ich habe folgendes Problem bzw. Vorgehen und hoffe, jemand kann mir bestätigen, ob das so korrekt ist oder ob ich etwas falsch mache.Offiziel von Veeam wäre es, wenn man die ganze virtuelle VM mit dem Veeam Backup for Office 365 (VBO) wegsichere. Allerdings ist dies bei uns so nicht möglich, da wir Veeam Backup und Veeam Backup for Office 365 auf einer VM betreiben. Dies zu ändern ist zurzeit leider auch nicht möglich, vielleicht in der Zukunft.Unser internes Backup für Microsoft 365 (inkl. SharePoint und Exchange Online) wird per Veeam Backup for Office 365 (VBO) auf unseren Netzwerkspeicher geschrieben. Dieses Backup wird zusätzlich mit Veeam Backup & Replication (VBR) auf Tape gesichert, um eine Desaster-Recovery-Option zu haben.Im Ernstfall funktioniert die Rücksicherung vom Tape auf den Netzwerkordner problemlos.Die Schwierigkeit ist aber: Wie bekomme ich die zurückgesicherten Daten wieder in Veeam Backup for Office 365 eingebunden, damit ich auch auf den bisher

Hello Everone, what is the default retention policy applied by Veeam Data Cloud for Microsoft 365 Flex? I noticed this was not covered during the onboarding process or while configuring the backup policy. Is there a default retention period that is applied automatically? Where can we find or view this default setting in the interface or documentation? How can we modify or override it if needed? Thanks in advance for your assistance.

Hello Everyone,We are using Veeam Data Cloud for Microsoft 365 Flex with a license for 250 users.During the initial setup, we tested with 1 user to validate the configuration. After confirming everything was working properly, we deleted this backup job and created a new policy to protect the actual 250 production users.However, we are still seeing the backup for the original test user, and the license usage shows 251 users consumed, even though our license count is 250.I have a few questions regarding this situation: How can we delete or revoke this test user so that it no longer consumes a license? If we keep the test user without removing it, will this impact production users (e.g., only 249 users protected)? Is there any automatic cleanup or retention process that eventually removes old test accounts from the license count, or must it always be handled manually? Any guidance on how to properly handle this case would be greatly appreciated.Thanks in advance for your support. 

Hi, I’m trying to make room in my backup repository for new backups.  My previous retention was set to 90 days and the oldest backup is from 45 days ago.  I changed the retention to 30 days, thinking that Veeam will then delete the backups between 31 and 45 days ago to make room, but it’s not doing that.  Is there a way to prompt it to do that?  I’ve tried to rescan the repository and also re-running the Backup Job, but neither seems to work.  Thank you!
