Hello Commvault Community, I’m working on reporting the total backup storage footprint of a single VM protected in a (deduplicated) HyperScale X environment.Using the Chargeback Details report, I noticed two relevant columns:https://documentation.commvault.com/2024e/software/data_views_for_chargeback_details.html Media Size: The amount of data that was saved on storage media during the specified time period, including aged and pruned data. For storage policy copies that have deduplication enabled, the media size for each job is calculated based on the average deduplication ratio of the copy. Where media size = application size * average deduplication ratio per copy. The average deduplication ratio of a destination copy is calculated by (tot

I am getting this error when running a backup job for 2 servers. Has anyone seen this before?  I have other servers that can backup successfully on this Commserver.Thanks!

Hello Commvault community! We are designing a backup strategy for two AVS sites, using SRM for replication and failover. We see two main approaches: Maintaining separate backup schedules and MediaAgents at each site, then manually switching backup jobs after failover and failback. This ensures data integrity and backup continuity but requires manual or scripted coordination. Replicating MediaAgents and backup disks via SRM to the DR site. This seems straightforward but Im not sure if it’s recommended by Commvault (because SRM’s block-level replication can cause metadata and deduplication mismatches, leading to backup failures or full resyncs).   Since SRM is already deployed and Commvault Auto Recovery is not an option, we lean toward the second approach. Are there other recommended practices or automation strategies for managing backup continuity in AVS + SRM environments?Thanks!

I have never upgraded the Commvault version before, so I have a few questions I'd like to inquire about. 1.Can I upgrade from SP16 to SP32 directly, or should I stop at an intermediate version first?2.Should I upgrade the HPK of SP16 to the latest version before upgrading the SP itself?3.My Commvault SQL version is 2012. Should I upgrade SQL first, or will the SQL upgrade automatically when I upgrade the Commvault SP to a version that requires a newer SQL version?  

I have a media agent (MA1)  that hosts DDB Cloud Disk 1 and DDB On Prem Disk 2. DDB Cloud is running out of space and I need to run DDB Compaction to reduce space until we get more disks.The outlined process says to1- Stop all jobs2 - Ensure that there is no SIDB2 process running on the MediaAgent.I can stop all jobs that are using the DDB Cloud Disk 1, no issues here, however the media agent will continue to run jobs for our On-Prem copies using DDB On Orem Disk 2 which will continue to have the SIDB2 running. Can I run the DDB Compaction for the Cloud DDB  even though the SIDB2 is running for the On Prem jobs?What would be the recommend action here?On a different note/request, is there a way Commvault Team could take a look at streamlining the compaction process

Has anyone use MECM (Microsoft Endpoint Configuration Manager) software to deploy or update Commvault software in the entire Commcell environment?  We are currently exploring this option but I dont have much information to begin exploring. Also I am not sure if this will even work or is supported by Commvault Any advice or suggestion is highly appreciated

Hello Commvault Community, Is there any information yet on how reconfiguration will be required for EWS running within O365 protection?Support for EWS for O365 ends on October 1, 2026. There's no information in the Commvault documentation yet – there's still some time left, but we're receiving inquiries from Administrators. Retirement of Exchange Web Services in Exchange Onlinehttps://techcommunity.microsoft.com/blog/exchange/retirement-of-exchange-web-services-in-exchange-online/3924440 Thanks in advance!  Regards,Kamil

We have been requested to provide a list of backed up content for an Azure Data Lake Storage instance.  Being a new workload, the intent is to validate the defined content (which uses multiple wildcards) is protecting the required data. Unfortunately, given the number of items associated with the ADLS workload, we don't seem to be able to extract a complete list of backed up items:CommCell Console seemingly can't handle the number of objects (1.2 million) CommCell Console reports are limited to 10000 objects. Command Center doesn't seem to give me an option to export the list. ListFilesForJob.exe doesn't seem to work at all. Are there any other simple options in 11.40.x?

Hello CV Community! I've had a similar problem in other environments before, but I didn't investigate further. Currently, after upgrading from SP28 to SP32, a communication problem occurred in one environment for an OLVM backup. The logs show entries like these: vsbkp.log20252 4f1c 10/30 13:13:59 1413471 CVClient() - File[Client.cpp], Line[105] netHostName[ABC.XYZ.com]: Warning, deprecated call to lookup client using net hostname.

Dear Vaulters, I was tasked to backup oracle VMs and i some VMs have ASM disk, I need to know if it is supported to backup these ASM disks because these disks have critical data that need to be protected. Regards

Hi all. I have a question regarding PostgreSQL.We have a PostgresSQL server with very little activity. We do a daily backup of the server with the option set to make a “Archive Delete” of the logs. Some times it happens that no new WAL files have been created, so the backup job goes to pending with the below error message: Error Code: [94:66]Description: PostgreSQL     Database: The Data backup has failed. Archive Log files are missing     preventing this job from completing on Instance     [~xxxxx_5434~] Client     [~xxxxxx~]. Please run a FULL backup.Source:xxxxxx, Process: PostGresLogBackupParent What can be done so I do not get a pending/failed job and so I do not need to run a full backup? Are there any secret additional setting there can be set to ignore this and make the job complete successful?  Thanks-Anders 

This is for fresh installation that I am logging into  command center for the first time. I have re installed the commvault, and also restarted IIS and tomcat services, with no luck. Any help would be greatly appreciated. Thank you 

Our customer is testing Axiom and wants to backup via Commvault...the vendor gave them a script to shut down the Axiom server so I’m sure how this is going to work?

I read the documentation on backing up VMware machines with IntelliSnap support and I've also read the considerations on this page here (streaming and intellisnap backups for vSAN datastore) and now I understand the importance of the second snapshot, this one via hardware, for the entire process, but what are the advantages of IntelliSnap backup using just the Virtual Server Agent Snap engine, not a 'hardware' snapshot of the datastore where my VM is hosted? Second question, how (or when) does the Commvault know that it needs to take two snapshots, the first one, a snapshot of the VM’s, and the second, a snapshot of the VMware Datastore? Third question, what do I need to consider when backing up multiple virtual machines from Datastore

Hi,Is there a procedure to migrate the commserve from windows to linux RhelI saw a someone ask this question before but it was quit a while backI couldn’t find any procedure in the documentation Best regards,

Dear community,We are currently implementing HPE StoreOnce with two MediaAgents. At the moment, the same StoreOnce device shows up twice in Commvault (one entry per MediaAgent). Jobs are working, but for HA and load balancing, should best practice be to add StoreOnce as a single library/store and associate both MediaAgents, or keep separate StoreOnce entries per MediaAgent?Additionally, ideally we need to separate specific backup workloads (e.g., VM backups handled by MA1, database backups by MA2). What is the recommended configuration for both high availability and dedicated backup flows per MediaAgent?I found also this from from documentation, but I’m not sure if this is my case here. 

Hi all,is there any way or feature whith which we can nearly 100% automatically validate our backups of VMs, DBs (MSSQL and/or Oracle) and maybe File Shares?Also the jobs/validations should be documentated within an report or something else.More and more frequently our customers are asking for such a kind of process/feature.In the past we walk through PoCs to handle the request with features such as Virutal Lab or VM Validation.But this kind of "automation" is not what the customers are looking for. Furthermore this way is missing the function of "randomization" of the to be restored objects (VMs).Do you have any experience with that request?

Dear Support Team,I would like to inform you that I am still facing issues with the backup process. I have attempted to resolve it, but unfortunately, I have not been successful.Your immediate assistance is required, as the domain server is currently not backing up. Please look into this issue as soon as possible. Best regards,Perwez Ahmed

I’m in the process of testing a new deployment and looking to enable Post Quantum Cryptography, building it out in my lab to confirm how it all works and following the process in documentation here: Enabling Post-Quantum Cryptography Config is an “all in one” with the CS & webserver on the same server on 11.40.10 media.

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
