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in understanding the reasons why Rocky Linux 9.6 has not been approved yet.Please note that installing Commserve on the outdated Rocky Linux 8 (outdated 4.x kernel) or 9.5 (not supported since 9.6 has been released) is not a viable option for us.Thank you in advance for your feedback!Best regards,Daniel

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. 

Hello Team,Please advise the Commvault use firewall ports for the communicaton of Commserve, Media agent and clients always to use 8400, 8401 & 8403.Any specific ports used for VMware VM’s, SQL, Oracle DB’s & FS backup’s.And for Auxiliary copies between two sites MA to MA which ports to be used which ports.Thanks in advance.

Hello,We’re going to deploy the commvault cassandra agent on a cluster (first time for both us and the client, as of right now they’re using medusa to manage cassandra backups) and the cassandra cluster will be in a different security zone to the commvault backend. As such, we need to make internal requests to open the necessary ports between zones.My question concerns the Staged type of restore, and ports 7000,9042/7001,9142 specifically.From what i gather from the commvault docs, the way a Staged restore works is, the tables are pulled from storage (in our case cloud storage, either S3 or DataDomain), temporarily copied to a directory on a Staging Location (where SSTableLoader runs for this type of restore) and then streamed into the Cassandra nodes. I’d like to know the following:The way i understand it, the host of the Staging Location needs to be the Media Agent. Please confirm if this is true and if not, what would be the alternatives for hosting this Staging Location. The stagin

Hi all, what’s the difference between File System and Application Consistent using VMware Tools and Application Aware Backup in the context of MS SQL and Oracle inside VMware VM? When do we use one vs the other?If I understand correctly, Application Aware backup will push application agent/plug-in, but not for File System and Application Consistent using VMware Tools. What are the other differences?Thank you.Regards,Aris 

If netapp is managing snap mirror directly, can commvault be configured to mount and create backup copies from mirror copy created by netapp? Or snap mirror process needs to be managed by commvault and only then a backup copy can be created from mirror copy?  

Hi Team, Even though I disabled the following option on CommServe, the agent installation screen still asks for a username/password or an authentication code. Shouldn't it be prompted? How can I disable it? Best Regards

After an unexpected upgrade to v11.40 from v11.32 all backups are now very slow. Low throughput and observed 99% DDB lookup. Backups aren’t completing. One Auxiliary copy has a huge 22TB of data that needs to be copied to tape. All these issue appeared after the upgrade

We are currently using Commvault v10, and we have data stored on tape that we need to restore directly to a Synology NAS Unit system, which is mapped to the media server. This is necessary because there isn't enough space on the media server itself. However, when I select the media agent for the restore destination, the network locations are not showing up. Additionally, since it's a NAS unit, we are unable to install the Commvault agent on it. 

Hi all,Our Commvault M365 backup INDEX, (with content indexing (v2) enabled), is driving the INDEX Server’s single disk drive close to 10 TB! Commvault’s guideline shows “Large” at 10 TB index disk and doesn’t list a higher tier.https://documentation.commvault.com/2024e/commcell-console/hardware_recommendations_for_index_server.htmlWhat’s the recommended practice beyond this — expand the SSD volume (scale up) or add index server nodes and redistribute with load balancing (scale out)?Is there any limit for a single INDEX (V2 with content indexing enabled) and what are best practices?Thanks for any real‑world experiences!Nikos

hi,For any of you still using tape on Linux MA’s, I was wondering if there’s a way to force the Expert Storage Configuration to use the alias (friendly names) created by udev rules for those devices and the changer?Setting up udev rules isn’t that hard and I know RH says that WWNN’s used “by-id” are automagic, but the names are never human intuitive. Plus we’ve seen some issues whereby rebooting the MA is a crapshoot that means sometimes the drives all work and mount media fine, and sometimes it’s no dice. I could never see the changes noted in the events and so created udev rules to try and keep things consistent, but the field can’t be edited in expert storage config under any circumstances, it just finds the ../scsi-blah devices and not any of the aliases.

The Security Assessment > Platform security page identifies a critical issue with the “File Activity Anomaly alert” not being enabled. Unfortunately, when I go into the Java GUI Console > Alerts > Configure Alerts, “File Activity Anomaly alert” doesn’t appear as one of the options.  I’ve searched the documentation but don’t see any steps on how to load this alert. Does anyone know how to load a missing alert? (The File Activity Anomaly alert specifically.)Thanks in advance for any help.Ken
