Veeam full backup retention

We observed our monthly back ups were deleted earlier than the 3 month retention set in the jobs . Short term retention is 35 restore points GFS is 3 months Repo is SOBR extents - Exagrid GFS Policy: Enabled, monthly backups kept for 3 months. Active full backup: Scheduled last monday of every month. Transform to synthetic full: Scheduled first sunday of every month. VSS settings: Application aware processing is enabled. We need to understand why the retention policy is not working as expected. Could you please provide a checklist of items to investigate, and explain whether the current settings would result in this behavior?

Running VBR 12.3.0. VBR backup server getting "Permission denied (public key)"

I am currently running Veeam Backup & Replication (VBR) version 12.3.0 and encountering the error "Permission denied (public key)" when trying to add a component server running Ubuntu 22 using SSH keys. Upon reviewing the logs on the Ubuntu 22 component server, I repeatedly see the following error: "Unable to negotiate with 10.0.0.8 port 64513: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1 [preauth]." It appears the VBR backuo server is offering outdated or non-compliant algorithms, such as diffie-hellman-group1-sha1, hmac-sha1, and also requires the deprecated ssh-rsa for public key authentication. As a result, my SSH connection from the backup server (10.0.0.8) to the component server fails, and I see the "Permission denied (public key)" error in the VBR console. I prefer to use SSH keys for authentication, and the SSH configuration (sshd_config) on the component server includes the following settings: GSSAPI Key Exchange Algorithms: gss-group14-sha25

VBR13 backup server certificate fails to install

Veeam newbie and first-time poster here (go easy on me!) … I am trying to attach an Ubuntu Linux 24.04 “minimal” server to a VBR13 test environment. This server is only intended to provide backup storage for VBR. While attempting to add the host as a managed server, I get the following error: “Setting backup server certificate Error: Remote failed with message: /opt/veeam/deployment/veeamdeploymentsvc: boost::filesystem::copy_file: Invalid cross-device link: "/tmp/VeeamUpload_20250328T170010Z/ServerCertificate", "/etc/veeam/certs/cert.p12"--tr:Failed to install server certificate” /tmp and / (where /opt and /etc reside) are separate logical volumes. Any ideas on how to troubleshoot this? VBR13 imported OVA (VMware), Console (Windows Server 2019), and Ubuntu server all on local LAN. Managed credentials for Ubuntu added in VBR Console seem to work. Thanks in advance!

Implementing Linux Veeam Proxies

Since we added Linux Repositories to our Veeam Backup environment in my post from last week, why not add some Linux Proxies as well? I will show you how in this post. And trust me…this one will be far less painless. But adding Repositories wasn’t so bad, was it? 😏 System Requirements The first thing you need to do is check what OS's, hardware, and software are supported. Supported Linux OS's are exactly the same as with Repositories and are listed below: Linux Proxy Requirements As far as hardware goes, your server should have a minimum 2-core CPU, plus 1 core per 2 concurrent tasks (take note, this is a peformance enhancement since v12, up from 1 core per 1 concurrent task); and minimum 2GB RAM, plus 500MB per concurrent task. But for best performance and to run multiple Jobs and tasks, you should have much more Cores and RAM than the minimum. As with the Veeam Repository, look to the Veeam Best Practice Guide for actual Proxy sizing guidelines. The remaining requirements depend on t

🔑 Enable MFA for your Veeam Account

Enabling Multi-Factor Authentication (MFA) or Two-Factor Authentication (2FA) is the best way to protect accounts from password theft or phishing. Therefore it’s recommended to enable such options, when they’re available. Since some time it’s possible to use MFA for Veeam Accounts, which are used to access the my.veeam.com portal or also the Veeam Community 😉 Login to your Veeam account at my.veeam.com and click on edit profile in the top right corner. At the bottom of your profile details, you need to click on “Enable MFA”. As a side note, even after enabling MFA this link still states “Enable” instead of “Disable”. On the following page, you need to click on “Set up authenticator application” and follow the instructions. While FreeOTP or Google Authenticator are recommended, you can use any other OTP app; for example I’m using Aegis. Afterwards it’s recommended to create recovery authentication codes, for the case that your MFA app isn't available. Of course you should not store tho

Veeam Version 12.1 - Malware Detections Query

Hello Veeam Community, I am reaching out with a concern regarding our Veeam version 12.1, as we are consistently receiving malware detection alerts on our VMs. The notifications specifically indicate: Potential malware activity detected: Too many files have had their names changed since the last backup; ensure they were not encrypted by ransomware. Potential malware activity detected: *.ttt (TeslaCrypt 3.0): 40 instances. Potential malware activity detected: *..txt: 2 instances. I have conducted thorough scans on both the VM and the backup, and no malicious activity was found. Could you please provide insights or guidance on whether this is a matter of concern, and if there are additional steps I should take to address this issue? Your assistance in resolving this matter is highly appreciated. Thank you in advance for your support.

Immutability on copy jobs - disk space requirements?

Sorry for the simple question, that’s no doubt been asked and answered before… Today we have VCC for our off-site cloud backups, and the immutability is provided by the “Insider protection” which in short means we pay for the privilege but we do not need to worry about disk space consumption over and above our actual backups. For lower cost we’re considering object storage, probably Wasabi, and we’ll want immutability there also. The thing I need to be sure of, is the disk space required. I am not sure if the copy jobs would have a specific backup mode, but with incremental, if they’re immutable, you’re previously overwritten backups are kept for longer? Disk space could be double what you have before? Thanks in advance for any insight on real world disk space requirements. Today, 27TB approx. is our VCC repo and as I say, the immutable data is retained at a fixed additional cost so we don’t know the size of that.

Failed to save Veeam CDP proxy: No connection could be made because the target machine actively refused it

I’ve been googling and am about to open a support case, but I’m checking here first. I have just built my first linux proxy servers using Ubuntu 22.04 LTS. Super easy, works great. Except I have two more that I’m trying to build as CDP proxy’s. I can setup as regular VMware Proxy’s, but when I attempt to install the CDP Proxy, I get the below errors. Error Failed to save Veeam CDP proxy: No connection could be made because the target machine actively refused it <IP Address>:6182 Error Infrastructure item save failed Error: No connection could be made because the target machine actively refused it <IP Address>:6182 This is my first time using Linux CDP proxy’s. I did have Windows Proxy’s in place but was having an issue with starting the CDP service on those machines after upgrading to 12.1 and decided to just remove those VM’s because they were 2012 R2 and are being replaced/retired anyway. Unfortunately, I’m not super well-versed in Linux so I’m learning here. This sounds like a netwo

Step-by-Step Guide to Upgrading Veeam Backup & Replication to Version 12.3

I was installing the VBR Console on my PC, and when connecting to the backup server, there was a version mismatch that the Veeam User Guide (HelpCenter) spelt out correctly. Here is the guide on how to “Install Veeam Backup Console on a Jump Server for Secure Access”, discussing all the prerequisites, installation steps, limitations and workaround. I searched through the community but could not find any post discussing the upgrade process for the latest version of VBR. Therefore, I will be discussing these steps below. Two months ago, December 3, 2024 to be precise. Veeam launched Veeam Data Platform v12.3, introducing powerful enhancements that significantly strengthen data resilience. This release introduces advanced capabilities that strengthen enterprise data resilience and security, as discussed in this blog post. Therefore, I will not be discussing these as there are tons of articles in the community discussing the features/capabilities as referenced below. https://community.veea

Sequence contains more than one element - Always ON

Hello everyone! I have a SQL environment where the error below started appearing after migrating between repositories: With this error it won't let me: Delete the jobs; Enable the job; Finalize the job configuration summary; Nothing about that specific job has worked again!! Background: Previously we needed to move the backup file and then map them to their target repository. Today we have the “Move backup” option: After clicking move, it tells me that it needs to move all the cluster backups: In addition to enabling Move via console, we can also choose which Job it will be linked to: That's awesome! Now let's get back to troubleshooting! I executed the sequence below to solve the problem: Clone the current job; Move the backups to the repository and cloned job; Run full backup; Continue transaction log; After that my job is working perfectly! Remembering that I am using Windows Agents within a protection group as good practices for Always ON protection

Veeam Agent for Windows / Encryption set by Client

Hi Community, a customer has the following requirements: some Windows Notebooks have confidential data on it, this data should be backup’d the only person who should have access to this backed data, is the owner of the specific notebook no Administrator should have access to this backup’d data My approach would be: Install VAW on the machine (not deployed/managed by VBR) configure a Backup Job directly on this system Repository can be an Object Storage or a Shared folder a Veeam backup repository would be managed by VBR and so the Backup Data and Encryption Settings could be accessible by the Veeam Administrator set Encryption within the Job (only the owner of this device has the Key) What do you think about it? Am I’m missing something here? Would there be a better approach?

Veeam Threat Hunter behind HTTP proxy

Just information for the Veeam community members. If your Scan Backup Job with Veeam Threat Hunter ends with the error " Unable to perform scan: threat signatures database is missing " and your Veeam Mount server is behind an internet HTTP proxy, wait for the next minor version of VBR, or contact support, they have a temporary workaround. Statement from support At the moment, signature updates do not work properly when an HTTP proxy is used - this is a confirmed issue that was found recently, and it is planned to be addressed in the next minor patch 12.3.1.

Veeam's All-Encompassing Malware Detection: Protecting Your Backups at Every Stage

In the ongoing fight against ransomware, companies are becoming increasingly resilient. Reports from Coveware by Veeam highlight a notable decrease in ransomware payments during Q4 of 2024. This progress is credited to several key factors, such as enhanced federal regulations, successful takedowns of major cybercriminal groups, and, most importantly, organizations' improved preparedness and resilience in responding to and recovering from encryption-based malware attacks.Data protection has undergone significant changes in recent years. Conversations have moved beyond topics like inline vs. post-process deduplication to focus more on security-driven areas such as workload immutability, incident response, and malware detection. Scanning backups for malware was never intended to replace traditional endpoint or extended detection and response tools. Instead, it serves as an additional layer of detection, enhancing a defense-in-depth strategy for identifying malware. Veeam offers the most p

Asynchronous request operation failed with synology SMB backup target

I have been having issues with the local file server/storage which is a Synology device running their latest up to date OS. I recently enabled SMB multichannel and Asyncronous read on the Synology. Unfortunately, my backups have started failing across multiple devices: 4/1/2024 12:32:10 PM :: Error: The network is busy. Asynchronous request operation has failed. [readsize = 4202496] [offset = 8585379840] Failed to restore file from local backup. VFS link: [summary.xml].

Agent failed to process method {DataTransfer.RestoreText} While I understand I can disable the feature and NOT have SMB multichannel on, it’s been great and beneficial. I’d much prefer I was able to support and take advantage here. Is this something I can address in some way? This is using the Veeam agent.

Comparing Motorcycle Safety to Data Protection Preparedness

The weather in Ontario has just started to consistently stay above freezing temperatures, even some days spiking up to 18 degrees (64F for my American counterparts). This has me thinking about one thing only; getting back on my motorcycle as soon as possible and enjoying the open road. However, as a new rider as of last year, I have prioritized safety and learning from others experiences. I do this by watching a Youtube Channel called "DanDanTheFireman". On this channel, Dan promotes motorcycle safety by reviewing footage of motorcycle incidents and providing after-action analysis of what went wrong, and would go have been done better. One of the methods/concepts that Dan teaches is called "MTC (Motorcycle Training Concepts) Awareness Stages". These 5 stages refer to the frame of mind a rider may be in at any given point in their ride. Later in this post I will look at these stages from a data protection mindset White Stage (Unaware) – The rider is completely unaware of their surroundi

Noted Malware file extension not found

I am trying to clean up my Veeam Backup environment. Since they launched the Malware detection many of my backup sets are marked as containing files that Veeam thinks are malware. Most file extensions are not and some are files that have been created from our internal Applications Development team. I am either deleting non-relevant files or adding the extension to the Trusted Objects list. One extension that Veeam marked as Malware is *.kill . It found 2 files on our file server with this extension. Confusingly, I have not been able to find these files when I search the file server. Can anyone point me to an application or process that could locate these files?
