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!

Commvault environment is on V11 SP40.6Hana instances reside on a cluster environment where the cluster IP is internal.

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

HelloIs the default policy enabled when creating the Exchange plan sufficient for clearing out older messages or mailboxes? Our default retention period is set to one year. However, when I check the Office 365 storage policy and the retention reason, I see "Data Aging Disabled" listed.

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

Hi all,Could you please advise me on how to back up Microsoft Office 365 (Exchange Online or SharePoint Online) specifically to an on-premise location?I would like to verify if my understanding of the architecture is correct: Access Node: Is it correct that I need to install an Access Node (proxy) within the customer's on-premise infrastructure? I assume this node handles the communication with the Microsoft Cloud and downloads the data.Storage Target: Is the local disk library selected as the destination storage when I Create a Microsoft 365 Plan? I am currently looking at this documentation link: https://documentation.commvault.com/2023e/software/getting_started_with_exchange_online.html#procedureProcedure: Verify that your environment meets the system requirements for Exchange Online. Add access nodes. Complete the Microsoft 365 service catalog. Create a Microsoft 365 plan. Add the mailboxes that you want to back up. Perform a test backup and restore. Is this the correct p

I need to know whether we can connect an S3-compatible repository provided by the customer (“cloud storage”) to Commvault in order to store additional backups as an “off-site” copy. Technically, we know that the connection is possible in principle, but the issue of encryption arose during the project. Could Commvault encrypt this backup with a separate key that is only available to the customer? It is crucial for the customer that the data is protected by its own key and can only be managed by the customer, rather than being encrypted with the general Commvault key. Otherwise, in the worst case scenario, the customer would no longer be able to access the data and would not be able to decrypt it due to the lack of a key. The question is whether it is even possible to restore data on S3 storage that has been backed up with Commvault without running Commserve.

Hi Team,From last couple of days HANA Backup is getting failed.In the Client system showing two instances (instance001 & instance002).
