Reporting machines without backup in the last 30 days

I was wondering if there is a way to use PowerShell to determine if a machine in a protection group has not backed up in the last 30 days. Obviously in Inventory there are protection groups that have machines in them and a status of “Last Agent Backup”. Is it possible to generate a report that displays that information? Basically I would like to put the script into task scheduler and have it run the 2nd and the 24th of every month. Any advice? # Load Veeam PowerShell ModuleImport-Module Veeam.Backup.PowerShell# Define protection group names$protectionGroupNames = @("Example Protection Group", "Example Protection Group 2")# Get the current date and time window$timeWindow = (Get-Date).AddDays(-30)# Initialize array to store report data$reportData = @()foreach ($groupName in $protectionGroupNames) { # Get the protection group $protectionGroup = Get-VBRProtectionGroup -Name $groupName # Get details of the machines in the protection group $machines = Get-VBRDiscoveredComputer -P

Need advice on speeding up retrieval Backup stats via PowerShell

Hi, everyone!   I have a PowerShell script that I use to retrieve some information about the daily backup sessions.  It works well, but I was trying to transition it from the Get-VBR-Job command to the Get-VBRBackup command.  Everything works but the newer script is very slow;  it went from a few seconds with the old script to 5-10 minutes with the new.  I was wondering if anyone could give me pointers on a more efficient way to get the session information or otherwise speed it up. Thanks in advance!!RobbOriginal script#backup JobsForeach ($JobObject in Get-VBRJob){ #write-host "loop number ${$jobobject.indexof()}" $session=$jobobject.FindLastSession() if (!($JobObject.JobType -eq "BackupSync")) { $JobOutput = New-Object -TypeName PSObject if (((get-date).AddDays(-1) -lt $session.Progress.StopTimeLocal) -or ($session.Result -in "Failed","None")) { $JobOutput | Add-Member -Name "Job Name" -MemberType Noteproperty -Value $JobObject.Name $JobOutput | Add-Membe

Powershell COM Help

Forgive me, as this isn’t strictly a Veeam topic, but I’m pulling my hair out.I’m trying to enhance a Windows Update Powershell script. The current script occasionally hangs when we invoke a COM CreateUpdateSearcher() method.$updateSession = new-object -com "Microsoft.Update.Session"$Criteria = "IsInstalled=0"$updates = $updateSession.CreateupdateSearcher().Search($criteria).UpdatesThis runs synchronously, so I can’t trap the hang. Instead, I want to use the BeginSearch() method that runs asynch (https://learn.microsoft.com/en-us/windows/win32/api/wuapi/nf-wuapi-iupdatesearcher-beginsearch). My problem is it requires an ‘IUnknown ISearchCompletedCallback’ object to be passed as one of the parameters. I don’t need this to be invoked, so it can be an empty object, but I can’t work out how to create an empty IUnknown object.$UpdateSession = New-Object -ComObject "Microsoft.Update.Session"$objSearcher = $UpdateSession.CreateUpdateSearcher()$objSearch = $objSearcher.BeginSearch('IsInstalled

Powershell - VBR 12.1 - Guest Index Data Scan Manager

IntroFirst of all: Happy new year to everyone!With Veeam Backup & Replication 12.1, many new security features have been added. One of these is the Guest Index Data Scan. For this, Veeam Backup & Replication uses a signature-based approach. During/after the backup job, the following malware activity can be detected:- Malware signatures specified in the "C:\Program Files\Veeam\Backup and Replication\Backup\SuspiciousFiles.xml" on the backup server- Multiple files renamed by malware- Multiple files deleted by malwarePlease read the Help Center documentation  to learn more about the details and how it works.In addition to the XML file, manual customization is also possible. You can add a malware signature that is marked as suspicious (Suspicious files) or that should be skipped (Trusted files) during the scan. See here. Questions you might askBut how do you know how many "built-in" and how many manually entered entries there are? Of course you can check the manual settings in the

VDC 365 Data Residency in Brazil's South Azure Region

Hi Community team! I have a doubt regarding the availability of VDC 365 Data Residency in Brazil's South Azure Region. I didn´t find this information in the documentation.The service´s docs state that backup data created by Veeam Data Cloud for Microsoft 365 or Veeam Data Cloud for Microsoft Azure can be targeted to and reside in any Azure region as end users request. Metadata is encrypted and stored in one of the following Azure regions: United States West. United Kingdom South, or Australia East.Do you know if storing the backups in Brazil's South Region in an LRS redundancy schema is possible?Choose the Right Azure Region for You | Microsoft AzureThanks so much for your help!

vcli - a universal Veeam CLI tool

Hi all, I’ve been toying around with the idea of a cli tool that works with everything and is related to the other post I put up today on the Go-Veeam-Auth that does authentication for all Veeam APIs. Anyway, I’ve come up with vcli a simple terminal app written in Go, allowing you to switch between APIs with minimal effort quickly. All the authentication is set up, so all you need to do is set some environmental variables, and off you go (no pun intended).The main output is JSON, but you can switch it over to YAML via a --yaml switch.The tool only does GET requests at the moment, as I wanted to gauge the interest before committing any more time to the project. Where the power really comes in when it is coupled with “nushell” which is a data-centric approach to shells. It makes manipulating json response objects a breeze and also allows conversion to other data formats. It also has a whole module system which I go into a bit on my GitHub. GitHub page: https://github.com/shapedthought/vc

Unveiling Cyber Threats: Harnessing YARA and Veeam for Malware Detection!

Greetings, everyone! Today we'll delve into the art of identifying basic file Indicators of Compromise (IoCs), crafting YARA rules to sniff out malicious actors, and seamlessly integrating these rules into Veeam Backup & Replication to safeguard our backups against potential malware threats. But before we dive in, let's take a moment to understand YARA and what its for. YARAYARA is an open-source malware classification tool used to identify and classify malware or suspicious files based on its signatures or rules. It is a powerful and flexible tool that allows users to create rules matching their organization’s needs or targeting specific threats. Moreover, YARA rules are like a piece of programming language, they work by defining a number of variables that contain patterns found in a sample of malware. If some or all of the conditions are met, depending on the rule, then it can be used to successfully identify a piece of malware. Indicators of Compromise (IoCS)Suppose one day a us

Unveiling Cyber Threats: Harnessing YARA and Veeam for Malware Detection! - Part 2

Hello everyone. Last time we explored how to identify basic file Indicators of Compromise (IoCs), develop YARA rules to detect malicious actors, and incorporate these rules into Veeam Backup & Replication to identify potential malware in our backups.Taking it a step further, today we will explore how to automatically generate YARA rules using YarGen. YarGenYarGen is a tool that generates YARA rules from a specified malware file. It identifies unique strings within the malware and excludes those prevalent in non-malicious files. This is achieved using YarGen's comprehensive database of strings and opcodes typically found in non-malicious files. Essentially, it creates YARA rules from strings in malware files while discarding those also present in goodware files.There are many variable and options that can be set in YarGen, today we are going to look at how it can create a YARA rule based off of a potential malware file. Back to basics - IoCSA user has noticed a folder called “freest

Enable/Disable Health Checks for Multiple Jobs

UPDATE (Feb 2024):It was brought to my attention recently that some of the cmdlets have changed in v12.x that may have broken one or more of the above scripts. I’ve rewritten the one that was pointed out (Veeam Agent Jobs) and tested to make sure it works. I can’t vouch for the others, but will try to get around to updating them all (if needed) and posting the updates here. Just be sure if you’re on 12.x or newer that you do thorough checks to confirm it works in a safe environment before attempting to run anything in production.------------------------------------------------------Hello again, everyone! Just sharing another useful PowerShell script to enable/disable Health Checks for multiple jobs. It’s handy whenever you have a large number of jobs which all need to be adjusted and would take a significant amount of time to do so.

Powershell - Automating Tape Verification in Veeam Backup & Replication

A tape verification a day….😉Tape backups are an essential part of data protection strategies as they provide reliable security and offline storage capabilities. However, ensuring the reliability and consistency of tape backups can be critical for regulatory compliance and ensuring data integrity.So I wrote a Powershell script (which has been floating around in my head for a long time) that uses the available Powershell cmdlet "Start-VBRTapeVerification" to regularly check tapes available in a media pool and marks them as checked with time stamps and checks the tapes again after a certain time (default 270 days). It also helps to increase data reliability and reduces the manual effort involved in managing tape backups. The script can be downloaded here.The following parameters can be utilized to customize the tape verification:MediaPool: Specifies the media pool from which tapes will be selected for verification. This parameter is mandatory. NumberofTapes: Determines the number of tape

Powershell - VBR Backup Scan - Updates

Hello community,you  probably know my many scripts on the subject of backup data scanning? I am happy to share with you what I am currently working on.Secure Restore / Scan BackupCurrently "only" Microsoft Windows machines can be scanned using Secure Restore or Scan Backup (see here). However the Disk Publishing (Data Integration API) allows us to publish a disk from different types of backups to a Windows or Linux host. The disk can have a Microsoft Windows, Linux, Unix or other file system. On top Veeam Backup & Replication v12.1 gives us many more options for scanning backup data. For example we now also can mark restore points as clean, suspicious or infected using a PowerShell cmdlet. What if i were to extend one of my scripts with this function? Said and done!New Script - New FeaturesThe new script presents all existing restore points from a Linux VM, Windows VM or Agent backup to a Linux host, scans the specified restore point and marks the selected restore point as infected

 Hi Community,YARA Scans, one of the exciting new features in V12.1 that I really wanted to start using.YARA is a great tool to help you search and detect malware like ransomware and alert you before it can do any damage.In Veeam Backup and Replication V12.1 you can only select one .yar/.yara file to use for scanning from the "C:\Program Files\Veeam\Backup and Replication\Backup\YaraRules" directory on the Backup Server.After uploading some YARA Rules to my Backup Server, I created an index.yar to include all the individual files/rules so I can run scans using all my YARA rules instead of a single YARA rule.A Yara rule looks like this:Where a Yara index file looks like this:If you select a file with an actual YARA rule the scan works fine, but since the file I selected was my index.yar file, the scan failed!After taking a close look at the YARA-Volume0.log file in (my case in) "C:\ProgramData\Veeam\Backup\FLRSessions\Windows\FLR__vb365.veeam.lab_\Antivirus" on the Mount Server I found

Automate Bulk Upgrade of VBR via VSPC

Last month I created a topic for a script I had created using Veeam Service Provider Console API to automate the upgrade of Veeam Agents (Automate Veeam Agent Upgrades via VSPC | Veeam Community Resource Hub) which also got featured in the last recap of 2023 which was a very nice end to the year for my first post! I was already planning on working on a script to automate the process of bulk updating VBR servers, but after it was mentioned a couple of times, I thought I would share what I have so far. If, like me, you work for an MSP, we have multiple tenant VBR’s kicking around it can be very time consuming when a new upgrade for Veeam comes out, to get this deployed on all of our tenants servers. Luckily, in recent updates, VSPC has improved the process of remotely upgrading VBR via VSPC. However, it is still a manual process that can still be time consuming going through each tenant VBR Server one by one. I wanted to find a way to automate this process.I could of wrote a script that
