Does anyone have recommendations for time settings on a Veeam hardened repo?  After researching, I’m seeing conflicting recommendations from use the internal CMOS clock, use an internal NTP server, or use an external NTP server.  Just wanted to see what some of the Veeam experts recommend.

As of the 27th March we have seen a significant increase in incremental backup size for our Microsoft 365 backup… Peaking at 800GB+ on the 31st! We have different jobs configured for different sources, for example we have separate jobs for:User Mailboxes Shared Mailboxes SharePoint Sites OneDrive SitesLooking at the size of each backup job, I think the increase in backup size is primarily due to the user mailbox jobs; the other jobs look ‘normal’ in terms of their size. Is anyone else seeing a sudden increase in backup size in the last couple of weeks?  Does anyone have any tips for pinpointing where the increase is coming from? 

Products:Veeam B&R Community Edition 12.3.1.1139 (Windows Server 2022) Windows Agent 6.3.1.1074 (Windows 11 Pro for Workstations, version 24H2)Using B&R Console I accidentally uninstalled CBT Driver from the Windows 11 PC, and now I cannot reinstall it anymore.The CBT driver is also missing from installed Windows apps and program list in the legacy Control panel.I tried to uninstall completely all components on that client, I removed it from my B&R Protection group, restarted it many times, but no avail.I also tried to install the standalone Agent, but the CBT driver install/uninstall option is missing from settings.Even command line method fails:Veeam.Agent.Configurator.exe -uninstallCBTDriverExitCode: 0Veeam.Agent.Configurator.exe -installCBTDriverExitCode: 20Errors:Failed to perform the operation.File existsThe only way I haven't tried yet is with command line by booting the PC from Veeam Recovery Media.In attachment: log file.Any ideas on how to solve?BTW, I’m wondering

Following on from my previous post, I am now in a pickle because after uninstalling a failed install of VBR 12.3 and reinstalling 12.1 the system is incapable of backing up my VMs. Need to completely uninstall all 12.1 stuff and do a clean install and forget about importing the config. Stay tuned.

Hello,When we have rental license how we can calculate how many VM can be protected by the available license?  

Veeam Backup & Replication Version 12.3.1.1139 – March 2025 Release OverviewVeeam Backup & Replication version 12.3.1.1139 was released on March 19, 2025. This update includes important security patches, new features, and enhancements. In this post, we'll cover the main highlights, such as security updates, improved platform support, and added functionalities.Security UpdatesVeeam Backup & Replication 12.3.1.1139 includes critical security patches addressing important vulnerabilities:CVE-2025-23120 (Critical - CVSS 9.9): This vulnerability allows authenticated domain users to execute remote code, making it a serious concern for domain-joined backup servers. It’s worth noting that this vulnerability only affects domain-joined backup servers, which goes against the Security & Compliance Best Practices. It's crucial for users to apply this update as soon as possible.New Features and EnhancementsThis release introduces several new features and enhancements across various pl

We should be plotting something!  As part of the presentation at VeeamON 2025 with ​@Geoff Burke, we introduced the new Grafana Dashboard, inspired by ​@jorge.delacruz's work for several Veeam products.The dashboard supports one or multiple clusters containing one or multiple nodes.For both the cluster and the nodes, the following details are available:Cluster and Node status Including Update and join/leave status Capacity status CPU & Disk I/O Network graphs (S3 and Internode) Internode graph will be empty if there is only one node in the cluster S3 Service Storage UsageThe following things are required:Grafana InfluxDB 2 Git Linux OSGrafana dashboard screenshotYou need to install some software if you are not already running a Grafana dashboard for Veeam. To get things started, follow Jorge's blog post. You could skip the Telegraf parts.After successfully installing Grafana and InfluxDB 2, you can continue installing the dashboard according to the procedure on the GitHub reposit

Someone on the Community reported the error of this post - “All backup proxies are offline or outdated” here -https://community.veeam.com/topic/show?tid=6645&fid=66I ran in to this issue in my HomeLab and opened a ticket with Veeam Support about it.  I was able to figure out the issue myself and wanted to post the fix steps here so that if you run in to this issue you can take the steps needed to address it yourself.This error does not seem to report anything in the log files which was the first thing I checked.  So, the steps to fix it are as follows -Remove the Proxy from the Veeam console using Delete. Remove the server from Managed Servers section - this will uninstall the components from the server. Log in to the Proxy server to ensure all components for Veeam are gone - if not remove them in the Control Panel Reboot the Proxy server Add the server back in to the Veeam Console as a Proxy server which will reinstall the components again. Validate your failed jobs by running the

Hi everyone, I have again encountered a problem related to backup using veeam backup, the error message is below.“Processing VM Linux Error: An error occurred while saving the snapshot: Too many levels of redo logs.

Over the past few months, I have been studying and testing different options for secure and immutable backup storage with Veeam Backup & Replication. I tried to compare the features of the available options:Veeam Hardened Repository Object Storage Repositories Deduplicating Storage AppliancesOf course, there’s no one-size-fits-all solution. The best choice always depends on specific requirements and the environment. Some products even cross traditional category boundaries, making direct comparisons even more important.I would love to hear your opinions on the advantages and disadvantages, your real-world experiences, and any corrections or additional insights you might have. In the article, I also summarized the key parameters of selected products.Any feedback is very much appreciated!Choosing a secure backup storage solution for Veeam

Dears, Greetings,I got an issue in my server as i am adding the machines as physical infrastructure.the issue is the job stuck at phase of storage initialized  then it fails after a while for windows with given error: and for linux machine it fails quickly with error  the thing is the network is fine and the connection to the NAS storage also so could you please help me in this error?Thanks,

Dear All,Let me ask for advice regarding the significant difference between the backup size and the repository size, which is causing inefficient storage usage and making it seem like deletions are not working properly. Below is my configuration: Source Backup: vMWare vCenter Destination Repository: Cloudian Object Storage Backup Frequency: Once per day Full Backup: Once per week Rettention: 7 Days Immutability: 5 days + 0 days (I modified the registry to set block generation to 0 days Capture:Rettention Policy (Job Configuration)Immutability (Repository Configuration)Results:Backup Size 5,20 TBRepository Size 15,6 TB My Opinion:Could the deletion be failing because the data is still locked by immutability at the time of the deletion? If so, what would be the correct configuration to avoid this issue? Could it be due to a failed checkpoint removal, as shown below:    Thank you for your attention. I truly appreciate your suggestions and assistance. 

 I currently have three separate data centers (DCs), each with its own Linux Proxy Server and Backup Repository. A single Veeam Backup & Replication (B&R) server, located in a fourth data center, manages all backup jobs across the three DCs.If this central Veeam B&R server becomes unavailable, all backup jobs across the environment would fail. To eliminate this single point of failure, I’m planning to deploy a dedicated Veeam B&R server in each data center. This way, each site will operate independently with its own Veeam B&R Server, Linux Proxy, and Backup Repository.  What is the recommended approach for implementing this setup? Will additional Veeam licenses be required for running multiple B&R servers? Once implemented, how can I migrate existing backup jobs and managed hosts from the central Veeam server to the new local Veeam servers in each data center? What is the other option for High Availability in this scenario ?

 Veeam’s latest report, From Risk to Resilience: 2025 Ransomware Trends and Proactive Strategies, reveals alarming insights into the evolving ransomware threat landscape. Surveying 1,300 IT and security leaders, the report highlights:69% of organizations experienced a ransomware attack in the past year. 10% of organizations recovered more than 90% of their data post-attack. 57% recovered less than 50% of their data.Key trends include:Data Exfiltration Attacks: Cybercriminals increasingly steal sensitive information without encrypting systems. Decreasing Ransom Payments: More organizations are opting not to pay ransoms, emphasizing the importance of robust recovery strategies. Law Enforcement Impact: Coordinated efforts have disrupted major ransomware groups, but smaller and independent attackers are on the rise. Collaboration is Crucial: Enhanced communication between IT and security teams, along with partnerships with law enforcement, strengthens defenses.The report underscores the im

My HelpDesk staff is in charge of removing tapes from our library. I have a Powershell script that emails them the tapes to be removed. They don’t have the Veeam B&R Console installed on their workstations. But they do have access to Enterprise Manager, from a web browser. Is there a way to export tapes from Enterprise Manager? I don’t see one. And since this is all they do with Veeam, installing the whole console is kind of overkill for them. Right now, they’re logging directly onto the B&R server itself, to do this. And I’d really like them to not log onto a server directly.

The install drive for Veeam B&R has 7.3 GB free space and there is nothing left that I can do to recover or extend the partition. I was wondering if I uninstall 12.1 would there be enough disk space to then install 12.3? I am running Community edition.

My understanding it that the best practice is to run Veeam B&R on a stand alone server, not domain joined.  It should have rdp disabled.  Veeam console should be installed on another server.  Our B&R server is domain joined.  I haven’t found any documentation on doing this type of migration.  The processes run under the local system account.  The credentials for things like vmware and storage arrays are stored in Veeam.  What am I missing that would blow up when doing this migration?  I would like to move it to a new server, not just remove the current one from the domain.  Our repository servers are windows and domain joined as well.  Should they be removed from the domain?  Seems like yes and that might be biggest issue.  Any insights appreciated.  

I was inspired by several forum questions, where I would like to present, mainly for new members.               There are requirements of several level of encryption. This could be enabled onBackup level – encryption inside of backup job (for VM) (for agent is encryption on repository and for plugin is on database level) Platform level – encryption of VM should be provided Transport level – encrypted transport of backups to repository For companies of sensitive data with highest security is not enough only to have encrypted backup and VM, but as well transport of backups. Hot-Add Method               Veeam can take a snapshot and create link of snapshot (cloned VM) and attach virtual disks on Veeam Proxy. This is provided via ISCSI Hot-Add method, where backed up VM and Veeam proxy are running on the same ESX host.               This is best practice. So, the best is used with so many proxy servers as how many ESX hosts we have, because is best performance, latency of backup.          

NetApp has released new All SAN Array models AKA ASA.R2 (ASA A1K, ASA A70, and ASA A90). These models will only support REST API. Veeam supports ONTAP integration only with ZAPI (ONTAPI). NetApp continues to support ZAPI and has no official EOA for it yet see NetApp doc below. I extracted a piece of this doc that says there is no firm date for EOA.CPC-00410 - Deferral of ONTAPI (ZAPI) End-of-Availability AnnouncementThis correspondence is an update to our previous announcement from February 2023, which stated the end of availability (EOA) of ONTAPI (ZAPI) in January 2024. Upon reassessment and recognizing our customers' continued reliance on ONTAPI, we have decided to prolong offering ONTAPI. Consequently, the EOA for ONTAPI is now deferred until further communication.Note: Veeam also only qualifies GA versions of ONTAP. Once the GA version is available, it will show up on our Veeam documentation site link below😀.Veeam NetApp ONTAP SupportThanks,Pete

Hi Community,I am studying a vSphere v8 course and in one of the course topics, I came across some information that raised a doubt in my mind. The information is as follows: In order for hotadd mode to occur, the proxy server must be running on the same ESXi host that the VM is running on. After researching further, I found this document https://techdocs.broadcom.com/us/en/vmware-cis/vsphere/vsphere-sdks-tools/8-0/virtual-disk-development-kit-programming-guide/virtual-disk-interfaces/virtual-disk-transport-methods/hotadd-transport.html that, in my interpretation, says the same thing. I would like to know if anyone has anything to contribute and clarify this question.My question is, if the proxy server is running on a host different from the host where the guest VM is running, will hotadd occur? As far as I know, hotadd occurs as long as the proxy and the guest VM have access to the shared storage.

I’m using Veeam Backup & Replication 12.3 integrated with a virtual infrastructure running on Nutanix AHV 6. I have a backup job configured with Application-Aware Processing enabled to back up a SQL Server instance hosted on a VM named SRV_GESTAOX. However, when running the job, I receive the following error:17/04/2025 17:09:22 :: SRV_GESTAOX : Object reference not set to an instance of an object.  17/04/2025 17:09:23 :: Job finished with error at 4/17/2025 5:09:23 PMAs part of the troubleshooting process, I’ve already tried using the local Administrator account and tested credentials using the format hostname\username. The credentials test in the Veeam job configuration passes successfully, so authentication doesn’t seem to be the issue.What could be causing this .NET-style error, and what steps would you recommend to further troubleshoot or fix the problem?
