Self-Hosted Q&A

Hello Commvault Community,  Does Commvault support backup of Proxmox VMs with a GPU card connected as PCI pass-through? There's no information in the Commvault documentation about whether it supports it or not, but the snapshot itself runs fine on the Proxmox side. When we try backup through the Commvault system, there's a problem with taking the snapshot, and the log shows the following information: ===--> FAILED                      Error creating virtual machine snapshot.  VM 103 qmp command 'savevm-start' failed - VM snapshot already started === When backup runs through Commvault, there aren’t manually taken snapshots on the virtual machine.Thanks in advance!Kind Regards,Kamil

Hello All,After adding a data file to the MSSQL database, it's normal for log backup to convert to full backup. However, after converting log backup to full backup, the server experiences excessive CPU consumption, reaching 100%. Is this normal behavior, what is the reason, and how can we solve it?Meanwhile, we don't observe too much CPU increase when running a normal full backup.

Disaster Recovery Query – IDM Application Backup Tapes (December & November 2025)The IDM application is hosted in DC1 (Onsite). Monthly full backups are taken every last Sunday of the month. These backups are sent to DC2 (DR Site). In December 2025, the IDM application required 5 tapes for the full backup. Out of these, 3 tapes became full and were already moved to DC2. The remaining 2 tapes were not yet full and stayed onsite in DC1. A disaster has now wiped out all onsite data, including incrementals, disk backups, and the 2 onsite tapes. We need to know in how many possible ways the application can be recovered using the offsite tapes. If recovery from December 2025 is not possible due to missing tapes, we need confirmation whether all November 2025 backup tapes for IDM are available offsite. If November’s set is complete, recovery should proceed from that month instead.

Hello I have the following:               RHEL client: RHEL 9Windows Commserve: Windows Server 2019No firewall exist between the two machinesWhen I check the box that says Restore Via CV Tools to install the Linux agent onto the client, I get this error:“Description: Failed to install File System Core Package, could not determine processor/OS type of client”I do have a case open with support but wanted to see if anyone else has had this problem and found a solution. I have not found a solution on the forum. 

Just noticed following coming change:On April 2 2026, Microsoft will fully retire Azure ACS for all tenants. Because of this change, you must reconfigure SharePoint Online to use certificate-based authentication. We recommend upgrading to Commvault Cloud 11.40 or a more recent release. All Commvault Cloud customers must reconfigure their SharePoint Online authentication method by April 2, 2026 or SharePoint Online backups will begin to break.

Hi All. I have build a new setup with MediaAgents and a CommServe installed with RedHat Linux. Is it possible to disable the root account like you are in a HyperScaleX setup where you need to enable the root access from within the CommandCenter. I really like this feature, so I would like to get et on my normal MediaAgents as well. I see that is possible via the CommServe bare metal setup and you can download a workflow described in the below link:https://documentation.commvault.com/v11/software/enabling_or_disabling_root_access_for_commserve_bare_metal.html Install and deploy the HyperScale OS Node Root Access workflow from the Commvault Store. But I’m unsure if it will work on my MediaAgents and my CommServe. Regards-Anders  

Hi guys, is there a possibility to get the subclientId of a client when searching for a specific content.E.g.:I have 3 subclients, 1 for drive c, 1 for drive d and 1 for drive e.Now I want to get the SubclientId for the path “c:\example”.Is there any possibility to get this? Maybe per RestAPI? BRJan

Hi All. I just checked the traffic to and from our CommServe in our firewall. I do see thousands of denies every hour from the CommServe to IP’s belonging to amazon (3.174.18.10, 3.174.18.80, 3.174.18.70…..) We do not use any Amazon services in anyway, so any one have an idea why the CommServe tries to connect to Amazon and how to disable what its doing? Thanks-Anders

I’m working with a customer to test Proxmox backups and am a bit confused.  When I go to the Proxmox config page I don’t have an access node which is expected since we haven’t set it up yet.  When I click on the link to download it, I get an VSA_x64.exe, which is a Windows executable.  From documentation I understand we have to install it on at least one of the cluster nodes which are a flavor of linux.  Is the idea to download the CV linux binaries using the VSA_x64 executable?  If so, what would be the proper package(s)? Also, it is a little confusing with the documentation as I’m reading it; do we need VSA installed on all the nodes in the cluster or just a single node to act as the access node?Thanks in advance!

Hi,additionally to my previous post regarding support for Rocky Linux 9.6 I now ask for support for Rocky Linux 9.7 or Rocky Linux 9 in general. I think this would be a curial step for Commvault to go from Windows to Linux and also allow customers to chose their distro.Why:On December 1st Rocky Linux 9.7 has been released. The Release policy for Rocky Linux: Rocky Linux does not support point releases once a newer one is available. Once a new minor point release is available, the older one is immediately considered end of life and users must upgrade to continue receiving security updates. For example, once 8.5 gets a general release, 8.4 is immediately end of life. SourceAre there any plans for changing the documentation to support Rocky Linux 9 in the latest point release?

Hi everyone,I am currently performing a hardware refresh/migration from a legacy Media Agent to a new Commvault HyperScale Edge (Single Node).Current Setup: CommServe is on a separate dedicated server. Legacy MA: Windows Server with local disk libraries (NTFS). New Setup: HyperScale Edge (Single Node). Already joined to the CommCell, and the HyperScale Storage Pool is created. Proposed Migration Plan: Since I cannot simply move the DDB/Disk (due to the architecture change to HS Storage Pool), I plan to do a Side-by-Side migration: Create a Secondary Copy on the existing Storage Policies. Set the Target Library as the new HyperScale Storage Pool. Run Auxiliary Copy to sync all data. Once synced, Promote the Secondary Copy to Primary. Decommission the old MA. My Questions: Is this the recommended workflow for migrating to HyperScale? When creating the Secondary Copy, should I expect any specific behavior regarding the DDB association, since the target is a Storage Pool? A

We are currently running several M365 clients over a resourcepool using a number of access nodes.Is there a way to limit the max amount of streams for a single access node to ensure its not overloaded?example: 100 M365 clients with 10 streams generate up to 1000 streams when run simultanously. However I would like them to be limited to no more than 50 streams per access node., so with 4 access nodes they would never use more than 200 streams in total.I’d rather scale with more access nodes as needed rather than try juggle the correct number of streams on all clients.Currently on Commvault 11.28

I have removed a client that we didn’t need anymore, but I forgot to first remove it from commvault.Now when the client is gone, I can’t remove it in commvault from the client computers?

 Question on GUI audit trail. It was my understanding that the audit trail captures all CommCell console gui operations that are being doneon the Commvault environment and many more. The Commvault documentation appear to show this is not the case.  Loading Commvault licence for example is not reflected in the GUI Audit trail.  So if GUI audit trail does not capture these significant changes or config change in the environment, then what Commvault report does it.  I raise this question as it is very important that we have some tracking as to what changes are being done in the environment and if the GUI audit trail does not track everything and no other Commvault feature does then it makes it hard to monitor any changes (unapproved changes ) done in the environment.Thoughts, suggestions and reactions are most welcome
