Has anyone seen this error?SQL database backups happen every 15 minutes, and this error occurs about every 20 jobs. Error summary Error code: [30:325]Description: Error encountered during backup.

Hello, I got email about  Vulnerability in the JDBC Driver for SQL Server (Microsoft) does its effect commvault sql agent?  https://msrc.microsoft.com/update-guide/en-US/vulnerability/CVE-2025-59250 

Hi all,I'm currently reviewing our Commcell’s Infrastructure Load Report and I have noticed the following:For the Linux MediaAgents, physical memory usage is around 15%, while virtual memory usage is approximately 70%. For the Windows MediaAgents and the Commserve (also Windows), both physical and virtual memory usage is similar.I'm wondering if this difference with the Linux MediaAgents indicates an underlying configuration issue or if it is simply the standard way Commvault operates in this environment.Also, at what point should I consider the memory usage to be a critical performance issue?Thanks!

Hi together, currently CV 11.40 does not support the Backup on VMs that are running on kubevirt/Kubernetes. https://documentation.commvault.com/11.40/software/protecting_kubernetes_with_commvault.html Are there any plans to support kubevirt? Regards.Michael

Hello, I am testing some restore of DevOps but when i am trying to restore something i am seeing only restore of Repository and not Board or pipeline. Hoe is its working? 

HiI am trying to setup a Commvault LiveSync with ver. 11.40.23 where the CommServ are running on Rocky Linux 9.5 (with the newest patches etc.). When I am looking at both Commvault SQL server databases they are in “ready” state. And I have been able to run file system backup without any issues using the Commvault media agent, that will be used with the server plan, that I have made for this LiveSync setup.I am able without any issues to create a DR backup, but when I am trying to enable the Commvault LiveSync then the first replication ends with this error:Error code: [30:325]Description: Error encountered during backup. Error: [0 - INFO: [Cannot open backup device '6600338a-4811-438e-ba06-75819758aea8'.

Hi All,Just checking if anyone is experiencing this issue with TrueNAS Scale as Disk Storage Target.We have multiple TrueNAS Scale that is having the same issues. We are getting Error code: 40:65 on all of them but they were working prior, and we confirm that the user we used has full access to the NFS share. Validate Job works just fine.Anyone seen this error before? We are on TrueNAS Scale 25.10-RC.1Error code: [40:65]Description: Error occurred in Disk Media, Path [\\192.168.172.30\commvault\FTKDP7_09.10.2025_21.16\CV_MAGNETIC\V_46927] [Permission denied error while accessing the path [\\192.168.172.30\commvault\FTKDP7_09.10.2025_21.16\CV_MAGNETIC\V_46927].

what is the difference here , do we need to perform both?Enabling Ransomware Protection for a HyperScale MediaAgent, vs Enabling Ransomware Protection for a HyperScale Cluster and in the documentation its says Ransomware protection is automatically enabled on new installations of the HyperScale X Reference Architecture. but recently i have done a deployment and its not enabled by default

why can't commVault do backup when postgresql is managed by patroni?

hey guys,All clients are v2 indexing at this point. I get an alert every so often that index backups haven’t ran in 30d for NDMP client. Each and every day there’s 100GB of inc. data being backed up, but the system scheduled Big Data Apps Index backups for that SP show that only “full” backups ever pick anything up, each day of the week when the incs run for the subclients of that NAS client, there doesn’t seem to be anything backed up at the index server level. Of course you can’t see any of this in the Command Center but is it normal for the classicIndexInstance backups to be zero bytes (and thus immediately age) in between Fulls?I see this phenomenon even on very small, minimal churn non-NDMP clients, so my question is - is there some threshold which determines IF an index server backup has anything new to write? For my very large-ish VMware SP’s and their Big Data Apps Index backup - those scoop up stuff every day, there’s never a 0 byte index backup, then again the SP has 3300 VMs

Hello Team,We are using Commvault backup with Commserve live sync option.Planning to configure new media agent and storage as mentioned in below.Newly two new media agent servers to be configured. Newly configuration of Disk libraries No need to migrate current backup data and instead will create new storage policies and new sub client jobs.Please advise is this configuration fine and any configuration level will be done of live sync.Thanks in advance. 

Since the upgraded we can no longer see the failed backups when we click it on the dashboard 

Hello there,Environment: netapp cluster (9.12) with Commvault 2023E Commserve (11.32.56)Current backup: ndmp to tape, 3 incrementals, one fullPossible new backup: cifs to disk w/ aux to tape, incremental and synthetic full only we are currently evaluating the switch from ndmp to nas/cifs backup, as ndmp has no “synthetic full”. this is disturbing when the full backup took 2 or 3 days for ~15TB.For this, I installed a spare server as standalone commserve (w/ eval license) to not disturb our productive system.Following the docs and several threads, I added the storage array and the SVM to Commvault and configured the subclient.I also configured snapdiffv3 on the netapp.The first initial full backup was successful, it created a snapshot where it pulls the files from.As I tried to do an incremental backup, the following happened:second snapshot createdsnapdiff v3 started, with the correct snapshots in the comparisonsnapdiff ended withCFSIScanEngine::ConfigureForChangelistScan(259) - Compar

Hello,We have an issue when authenticating java console/CC via AD login (no SSO).After only one failed attempt the account is getting locked. In AD it is set that account get locked after 5 failed attempts.I'm under the impression that this behaviour started after we enabled MFA.Any idea? 

Hi All,Commvault regularly frees up space on magnetic disk library, during this period of time I see high disk activity but I don't see any Jobs in Job Controller. Restore jobs performance considerably drops if we run it at the same time.Is there possibility to view and control/pause such cleanup/reclamation jobs? It would be useful when you need to do restore as much fast as possible. 

Hi all,I have disabled SSO on my CommCell and created local CV accounts.I have enabled CV MFA for these user accounts and restricted master group access to a few users.In the event of a cyber attack I have create an admin (master group) account with no MFA. This account has a crazy long password and will not be used for day to day activities.My question here is how safe is this account ? and is there a way to secured it with MFA, where MFA will work when I have no email / internet access for ?Thanks  

I am wondering if there is a config issue with my remote cache on the Livesync node.The software cache on the commserve (primary) is: C:\Program Files\Commvault\ContentStore\SWThere are 2 remote software caches configured:[primary_SQLDR] = NOT ENABLED = C:\Program Files\Commvault\ContentStore\SW[livesync_DRSQL] = ENABLED =  C:\Program Files\Commvault\ContentStore\SWwhere “primary” and “livesync” are the hostnames of my primary and livesync commserves.The [livesync_DRSQL] = ENABLED one is “out of sync”, and the “SW” folder doesn’t even exist on teh server. I also notice (in several places in the documentation) that it appears that on the DR livesync server it should be C:\Program Files\Commvault\ContentStore2\SW?  On my commserve and livesync servers I have both C:\Program Files\Commvault\ContentStore and C:\Program Files\Commvault\ContentStore2 folders and its not super clear but it seems that ContentStore2 is for the Livesync/secondary onlyso: Should I create the “SW” directory in C:\

Hello everyone,I would like to know when Commvault Commserve will be officially supported and available for installation on Rocky Linux 9.6. Currently the documentation only list only 8.9-9.5 as supported versions.Are there any plans for certification or compatibility testing? If support is not yet available, I would also be interested in understanding the reasons why Rocky Linux 9.6 has not been approved yet.Please note that installing Commserve on the outdated Rocky Linux 8 (outdated 4.x kernel) or 9.5 (not supported since 9.6 has been released) is not a viable option for us.Thank you in advance for your feedback!Best regards,Daniel

Good day allI was trialling the V11.40 SDK today, but notice that the Commserve Role doesn’t appear to be part of the Media Kit yet. Has anyone else experienced this? I also notice that V11.40 is not yet available on the Store.

Hello Team,We are planning to implement new media agent servers in main & secondary sites.The new MA servers are having 4 network ports.  For backup and replication using dedicated network switches and also these two data traffic to be seperated. Please advise.
