How to install a YARA rule with Veeam

We’ve updated the Script Library section to include YARA rules. I’ve made a quick video (sorry for the cheesy graphics...) on how to install a YARA rule from this site and perform your first scan!

Pre-Check for update VEEAM to Version 12 using VMware

Hello together,before you update VEEAM to Version 12 using VMware vCenter/ESXi please check VMs HardDisks for duplicate UUID. In Version 11 this was never a problem. In the new Version VEEAM checks the UUID and backup will fail.VMware has no problem with that most time. But they know the Problem - https://kb.vmware.com/s/article/2006865This command will find any HardDisk with duplicate UUID - please note that this is VMware PowerCLI commandGet-VM | Get-HardDisk | Select @{N='VM';E={$_.Parent.Name}}, @{N='Uuid';E={$_.ExtensionData.Backing.Uuid}} | Group-Object -Property Uuid | ?{ $_.Count -gt 1 }As Service Provider such changes in VEEAM are a total disaster!!

VBR Generate Syslog Event Filter XML File

Starting with Veeam Backup & Replication 12.3, it is possible to exclude specific events from being sent to the Syslog server. This can be done manually per event, or you can import an XML file with the events to be filtered.Handling this task and finding the necessary information can be time-consuming. Executing this task manually is “boring” and error-prone, so I created a simple PowerShell script to make the process easier by generating an XML file based on your chosen filters. Whether filtering by event IDs, categories, or specific filter types like Info, Warning, or Error, this script makes this task more fun.🕺🏿💃🏽For more details and examples of usage, check out the README in my GitHub repository.Happy filtering - It’s the most wonderful time of the year to write scripts 😉🎶Steve💚

Powershell - OneDrive for Business File Scanner

Hello Community!It's been two years since I published a script for a OneDrive for Business file check in this community. And even back then I had the code ready that also checks recovered files for possible malware. Of course, Microsoft 365 also has certain mechanisms, which are documented here.Trust is good, control is betterI have now taken up my idea again and packed it into a new script. The script restores files from the lastest OneDrive for Business restore point and scans them for threats using Windows Defender. A single file can also be restored and scanned.There is a "beautiful" listing when the scan has detected something.Please read the README document on my GitHub for more details on how to use the script.⛔Important!⛔ Make sure that there is sufficient disk space in the directory where the files are to be restored. Also use an empty directory to save the data, as the script cleans everything up after execution.Question to the communityWhat do you think of a script that rest

Create NAS backup job with PowerShell

Hi everyone, I'm using Veeam for quite a while now but recently we added some NetApp ONTAP devices to the storage infrastructure. And for each also a NAS Filer object under unstructured data. I can select a NAS Filer and create a file backup job easily. But I want to automate this if possible.I can use Get-NetAppHost to get the ONTAP device and then use Get-VBRUnstructuredServer combined with Get-VBRNASServerPath but I can't link it all together… Also, when I look at an already configured job I cannot reverse engineer this to usable PS code.Can someone point me in the right direction to create a file backup job of a share on a NAS filer with PowerShell?

Immutable Storage actual disk used per folder

Inherency:Since we bill by actual disk usage for our client utilizing CloudConnect, the existing reports are non-functional for reporting and billing (They report pre-deduplication/reflink data).  It took a while to figure out, but there is a way to calculate actual disk space used on a per directory on an immutable repository.Solution:Using: https://community.veeam.com/blogs-and-podcasts-57/check-reflink-and-spared-space-on-xfs-repositories-244 I have extrapolated a script that will give the disk usage of each folder (IE: client) on an immutable repo.  This isn't "Data used"; that is what Veeam reports.  This is "Disk Used".  The actual size on disk after reflinks (duplicated data is only counted once). A note about this script; it appears that the original blog entry is wrong on the size of a block.  They attribute it to 4096... which is true... on disk... but the utility used explicitly gives the information in block sizes of 512:https://linux.die.net/man/8/xfs_bmap"units of 512-byt

Veeam Hardened Repo: Firewalld security zones

Disclaimer: This is only provided as a reference. Make sure you understand what you are doing before executing this in your own setup (eg test in a lab). Since this is modifying the firewall, you might lock yourself out remotely if you are executing the steps incorrectly or you have a slightly different setupIf you are running RHEL or any experimental derivative (in my case Rocky 8.8), you can use firewalld to configure the firewall. Firewalld uses zones in which you can allow ports or services based on the incoming interface or IP sources. By default, all the traffic is “allowed” based on the rules in the public zone (or better the interfaces are by default assigned to the public zone). You can test this with# What is the default zonefirewall-cmd --get-default-zone# What are the active zones, by default only the public zonefirewall-cmd --get-active-zones# List all the rules in the public zone, this is by default ssh cockpit and dhcpv6firewall-cmd --zone=public --list-allYou can howeve

Change Rate Script?

This is me being a bit lazy, so apologize in advance. Does anyone have a script, or know of a VBR type report which retrieves change rate for VMs in a Backup Job? Obviously I know about VONE, but we don’t use that (maybe I can do a temp 30-day trial install...but would like something a bit quicker and temporary). I’ve run into a situation since last wk where 1 or a few VMs in a job have changed the backup rate significantly since last wk, by almost 10-fold, causing me to run out of space not only on this Job Repo, but my storage array! I’m trying to work through it, but would like to know the culprit(s) to let the app owners know to chill! haha There was a couple app VMs with updates, etc since last wk, so I have an idea a little bit of what’s going on. But, I’d like to pinpoint things a bit better.Thank you Community!

Add new API permissions to existing App registration for VB 365

With the release of the version 8 of VB 365, some additional permissions are needed on the registred app. Nothing to think about when you’re deploying a new app, but when you’re upgrading, you coudl re-use the existing app and extend it with the new requirements. I’m not a programmer, but I’ve tried to setup a small powershell script that based on your Application ID adds the necessary rights and also adds the app to the Global Reader role.Feel free to check and modify it !

AsBuiltReport for Veeam Backup for Microsoft 365

Hello,These last few weeks I have had the time to give some attention to the AsBuiltReport.Veeam.VB365 report. This time a lot of improvements and new sessions were added to collect much more information about the Veeam Backup for Microsoft 365 infrastructure. Here I provide you with the changes:https://github.com/AsBuiltReport/AsBuiltReport.Veeam.VB365/releases/tag/v0.3.0 Now the reason for writing this post is to share with all of you about a project I have been working on in my spare time and it is about Diagramming the Veeam infrastructure. In this new version of the AsBuiltReport.Veeam.VB365 report I added the ability to create a simple diagram of the deployed VB365 components. This tool uses Graphviz and the PSGraph module to generate the diagram. Here is the main link where you can see how to use the report:https://github.com/AsBuiltReport/AsBuiltReport.Veeam.VB365In this link you can find the code I use to generate the diagram!https://github.com/AsBuiltReport/AsBuiltReport.Veea

Powershell - VBR Backup Scan - YARA ready

Hi Community,after Rick's announcement (thanks for the initiative), I couldn't resist creating another script for the community.As documented, you can add one YARA rule file to the scan process. But what if you want to use multiple YARA rules? Of course you could work with a so-called index file, which refers to the individual YARA rules, but this brings a problem with it, because the YARA rules are stored on the VBR server, but the scan process provides the backups on the mount server and only one YARA rule can be used (This is a topic for another blog post - stay tuned).  What if we would like to use all YARA rules from Rick's Top 10 Ransomware Threats  blog post for a scan? And we don’t want to click so many times in the UI? This Powershell script can help. You can select all YARA rules, only selected YARA rules or all YARA rules if no selection has been made after 30 seconds. The script needs the backup job name and the hostname which has to be scanned. .\vbr-scan-backups.ps1 -Jobn
