Self-Hosted Q&A

Hi Vaulters, In order to implement a Vault site which will contain one MediaAgent in it, we wanted to restrict the communication of this MediaAgent to only the CS + MAs in Prod site and make connection only be established through the Vault site. To make things even securised, we wanted to use a dedicated port for the Vault MA unstead of the defaults 8400/8403. Seems this can be achived through One-Way network topology while setting : Vault MA → Prod CS/MAs.But not sure about the customized port to be used, as from OS/Network perspective only the custom port will be allowed between the Vault MA and Prod CS/MAs. Should the custom port be set in the below screenshot during topology creation or set as an additional setting in the Vault MA (nCVDPORT) or both ? How to let CV know that the communica

Hi,We have SP36 commserve and we tried to use the Nutanix Image with 11.36 available for download, but it doesn’t contain the /etc/initfrel_sc script that allows FREL to run. Please check the following image.https://cloud.commvault.com/commandcenter/#/softwareStore/33251The documentation appears to be out of date.https://documentation.commvault.com/2024e/commcell-console/deploying_file_recovery_enabler_for_linux_with_nutanix_acropolis_hypervisor_ahv_cluster.html I need the correct package containing the FREL activation script. Do you have any other image for Nutanix FREL? Regards,

Hi all. How would the procedure be, to do a Linux OS refresh from Rocky Linux to RHEL? The servers have local OS, ddb and index disks, and the MA’s have block storage mounted disks for the library.The hardware need to be reused, so I just want to reinstall OS, but keep DDB, index, library data, server name and IP, so that the server can continue operations after the Linux OS refresh.. Any suggestions on how to do this and any recommendations appreciated. Regards-Anders  

Hi All, i´m looking for an prcess list for the rocky linux vsa template. We are using trendmicro as av vendor and we cant exclude an path for the processes so we need to exclude the processes manually. I did not find any list and ariel also not :)  Do you have an idear ?

Hi,I am encountering an issue with VSA backups on a Nutanix AHV cluster.The Scenario: I ran a manual Full Backup for a specific VM. The job status is "Completed". Immediately after the job finished, I tried to browse and restore a vDisk (scsi-1). The file appears in the index, but when clicking restore, I get the error: "Cannot Restore since there is no data available" The Anomaly: Restoring the same VM from the scheduled nightly backup works perfectly. The issue seems specific to this fresh manual job.Environment: Commvault VSA for Nutanix AHV. Disks are standard vDisks (not Volume Groups / iSCSI Guest). Proxy has full access to the container (verified by the successful nightly restore). Question:

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

HiI have a problem with a Commvault LiveSync setup running with Rocky linux ver. 8.When I am doing a test failover all is looking good. But when I am trying to do a maintaince failover, the maintaince failover fails.It is faillling under the recovery process on the standby node with the error saying “Failed to generate new CS client certificate”.  I have been trying to stop the selinux and firewall on both CS, and still are getting this error. Does any have a idea on what is the problem?

Hello Commvault Community, We have this situation:There are MS SQL servers that have transaction logs backup during the day. Full backups are made only outside working hours. Sometimes, however, it happens that during the day, for some reason (the logs show that communication with the media agent was interrupted), a broken chain is made and the transaction logs backup is converted to full.Unfortunately, we can't do full house during the day, because it overloads the source servers. What we tried to do:1. Uncheck "convert" in the subclient properties - it did nothing, the backup was still converting.2. Do a "full data management" subclient blackout window for these servers within business hours. The workaround for blackout windows should work in theory, but if the conversion takes place, the job is still process in the JobController as "transcational log" and not full (although in reality it is already ful

Hi All, there was an option in the cloud.comvmault.com webconsole portal to use the staging feature. The DR Backup was uploaded and than an cs with restored db was created.

Hello Community and Happy New Year!In a client, we have a primary storage policy using a Disk Library (DDB). Needed also a tape out (copy-2). The HPE tape library is already configured and accessible via MediaAgent.For these auxiliary copies (Copy-2) to tape, we need to create two distinct groups: Weekly backups with 4 weeks retention Monthly backups with infinite retention   What is the recommended best practice?Stick with the default storage pool for both aux copy types (and rely on retention rules/scheduling to differentiate)? Or create two dedicated storage pools (e.g., "Weekly_Tape_Pool" and "Monthly_Tape_Pool"), assign specific tapes/drive pools to each, and configure the aux copy operations/rules to target the appropriate pool based on backup frequency?Also, it’s important the tapes to remain strictly separated, no mixing of weekly and m

Hi CV Community,We are Planning to do a domain name change on our Commserve and media agent. for example we are currantly used commserve.abc.com and media.abc.com but we need change the domain name commserve.xyz.com and media.xyz.com.

Hello All,Our customers are increasingly requesting to update their NetApp storage to Ontap 9.17.1. In addition, new systems are increasingly being delivered with 9.17, and we need to perform a downgrade. (if still supported by the hardware)Are there any plans to release Ontap 9.17.1 or even 9.18.1? Grateful for any help!

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
