Self-Hosted Q&A

Hi Community,  I’m currently forwarding logs from Commvault with a external monitoring tool, and then use a DB Connect tool for this. After a recent upgrade, I can see that my queries for the view [CommServ].[dbo].[CommCellBackupInfo] is now being masked for the variable clientname. It now shows, for example: “eexxxxom”. instead of “example.com”. I found this KB: SQL Dynamic Data Masking about this.Questions I have relating to this are:What privilege does the user need to have for this to not mask? Currently, I have “read-only” rights, which only have rights to read and connect to the database. What else would I need for this to work? Or, are there any way to disable this in Commvault/the SQL database in the CommServe?Kind regards,Daniel

Hi,actually we do not encrypt our backups.Make it sense to encrypt them?Thanks and RegardsDennis

Hello Commvault Community, I’d like to ask how the CS hostname mechanism works during the production failover process.   If both CommServe servers, passive and active, have different “CommServe Hostnames” and the CommServe Hostname value isn’t changed for Client Computers (production servers) after a production failover, is this the correct behavior, or should this parameter be automatically updated in Client Computer Properties? CS Active: CS_ABC (Instace001) FailoverNode1: Fo_ABC (Instace002) CS Passive: CS_XYZ (Instance001) FailoverNode2: Fo_XYZ (Instance002) After a successful production failover to CS_XYZ, the environment works correctly without any problems, but all Client Computers still have CS_ABC listed as the CS Hostname in their properties (it acts as passive CS after the production failover). Is this how it’s should work, or should the CS hostname be automatically updated on all Client Computers as part of this production failover process?    I haven’t found any such des

I would like to deploy a new CommServe server on Linux using SP 11.40. My current CommServe is running on Windows with SP 11.36. I plan to set up the new CommServe as a standby node in advance.Could you advise on the best practices for this setup?The operating system I am using is Rocky Linux. I have provisioned an additional disk for the Commvault installation and software cache, which is mounted at /opt/CommvaultData.What are the initial steps I should follow to ensure a secure and reliable installation? For the installation of SP 11.40, I would like to first deploy two new passive nodes on Linux, and only then perform the failover to Linux.I also have a question regarding the software cache. With the new CommServe on Linux, I have configured a new software cache for Windows and enabled it as a remote software cache.How can I ensure that, during update installations, clients automatically use the correct remote cache? Specifically, I want Windows clients to use the Windows software c

Hi,on our B2D library there is one mount path since weeks full. Mount path usage is set to “Spill and Fill”.Why is that path full?RegardsDennis

Hi all,In the Commvault Engineer training I told the students about MediaExplorer. One of my students remarked that MediaExplorer is only available for Windows. Since there are more and more MediaAgents on Linux (and therefore backups to Linux volumes), is there something similar for Linux? Or can we connect a Linux volume to a Windows server and use MediaExplorer on that server?Any tips are welcome. Thanks and kind regards,Henk

Hi everyone,I have a question regarding the restore of Teams planners. I have a customer tried to restore the planner of a teams channel but the restored planner is empty. When restoring to disk, the folder structure is created to mirror the teams\channel\planner path but the resulting folders are empty.I already found that they did not have planner items enabled in the Office 365 plan which was why the original restore was empty. I enabled this option last week and since that time backups have been running without issue.I have just browsed the latest backup of multiple teams with planners but all planners are showing empty.Is there anything else I need to do to be able to restore the planner items? The Commvault environment is running 11.40.47.Kind regards,Paul

Hi all,I’m looking into the default configuration for SQL transaction log backups in Commvault and noticed that log backup with caching (Log Commit) is enabled by default.  From what I understand, the log backups are first cached on the MediaAgent and then committed in batches to the CommServe based on a defined interval. I also see that even if log backups run frequently, they don’t appear as individual recovery points in the timeline, but are still used for point-in-time restores.What I’m trying to understand is how useful this setup is in practice. Since log backups are not visible as recovery points in the timeline, does this approach actually help you in real scenarios?Is anyone actively using this default behavior and finding it beneficial, even though you don’t see those recovery points directly?Would be interested to hear your experience.   Best regards, Nikos

Hello Team, Currently we have two physical media agent servers and using only index cache. The deduplication feature is enabled on target end (Dedup appliance). Now we want to add two new media agent servers and after few days will remove old media agent servers. Shall we move indexing data from old media agent to new media agent servers.

Hi Team,We have a requirement where a company is separating from its parent organization and establishing a newly created Commvault environment.As part of this transition, they would like to migrate their long-term retention backup data from the existing on-premises environment to the cloud within the new Commvault setup.Please confirm whether this migration is supported and advise on the recommended approach to perform it.Additionally, please provide the following details: Prerequisites and requirements Supported migration methods High-level implementation steps Any limitations or considerations that should be taken into account Your guidance on this would be appreciated.Thanks,Rahul Raina

Hello community, we currently have the following situation with our synth full in our plans:Copies:Primary - 15 days / deduped Sync copy to tape / 30 days Selective copy to tape (monthly fulls) / 1 yearSynth fulls:Automatic every 15 days On the 1st every month for extended retentionPreviously I reduced the automatic synth full to 15 days to better align with the retention and therefore have better aging regarding the cycles.We will also enable WORM on the Primary in the near future so I want to leave it this way to also align with DDB sealing.My question is about the synth scheduling:Because of the 15 days schedule I now encountered a situation where a synth ran on the 29th and then shortly after on the 1st because of extended retention.This of course causes extensive amount of data on the sync copy as the full backups get expanded onto the tapes.Should I sacrifice the automatic schedule in favor of a manual synth full backup (e.g. every month on the 15th) or are there other ways to av

Hi Vaulters, Hope everyone is doing well. We currently have an Exchange On-Premises user mailbox archiving solution implemented within our environment using Commvault. All components of our CommCell infrastructure (CommServe, MediaAgents, Web Server, etc.) are hosted within the internal network, and the solution is operating as expected. End-users connected internally are able to seamlessly access and retrieve their archived emails (Recall functionality) without any issues. However, we now have a requirement to provide external access to this archived email content for a subset of users. These users connect through a VPN, which places them within the DMZ network segment rather than the internal network.We understand that it is possible to deploy a dedicated Command Center instance within the DMZ to handle external access use cases. That said, we are unclear about the complete architecture and configuration required to make this setup fully functional. Specifically, we would like clarif

The number of partitions created is determined by the number of DDB MediaAgents selected during configuration: 1 MediaAgent selected Two partitions are created on the single MediaAgent. 2 MediaAgents selected Two partitions are created on each MediaAgent, for a total of four partitions. 3 to 6 MediaAgents selected A total of six partitions are created and distributed evenly across the selected MediaAgents. More than 6 MediaAgents selected The first six MediaAgents are used to create the six partitions. The remaining MediaAgents are assigned the Deduplication Database (DDB) role only. The software automatically assigns the deduplication database (DDB) path on the MediaAgent without requiring user input.Link Configuring Disk StorageI couldn't quite understand the final part where more than 6 MediaAgents are selected. Can someone explain it in other words?

Hi All, I'm looking for a way to detect newly registered clients on CommServe that haven't had policy configuration done.Perhaps a REST API, qcommand, or a database query? What criteria should I use for detection? Should they not have had a backup for a few days, or should they not have policy assignments, etc.? I want to use this to feed an automation system, so sharing use cases or best practices would be helpful.Best Regards.

I have a small CommCell with a CommServe on 11.32.115 running on a build of Windows Server that needs a refresh.I could stand up a new VM with the same IP and hostname and do a DR DB restore and I guess I’m back up and running quickly with a clean build?But I noticed Commvault now offer a Linux CommServe and a pre-configured OVA appliance so I’m wondering if this is something I should be looking at instead? The current environment doesn’t use “plans” it’s all traditional storage policies and copies and schedule policies to run jobs out of business hours.I don’t tend to use Command Center I tend to use the Java UI but I guess that’s out of habit.It’s a pretty small and simple environment with just a few Windows file agents and a NAS agent pulling some UNC paths in.What would people suggest please?

Hello, Can Commvault support Gmail Backup or Archive? 

(CV 11.40.47)We have several Exchange Online backups running for our customers, and each has their own little slice of heaven dedicated to them in our datacenter. They have their own dedicated access Nodes, so they are isolated from each other on our end.We're seeing Exchange Online backup performance is degrading across the board. Because the customers all have their own independent MS365 tenants, it would be strange if this was a Microsoft throttling issue hitting all of them at the same time, no?I am not seeing this performance hit on their Teams, SharePoint, or OneDrive backups.anyone else seeing degraded performance with Exchange?

Hi all,I have a problem with the functionality of the filters in the views in Jobs - Job history, when I want to filter by Start or End.When I use the condition "Relative" (1 day), the list of jobs is displayed.When I use the condition "Between" (yesterday-today), the error "Something went wrong" appears.When I use the condition "Older than" (anything), "No results found" appears.There is a similar problem when using the time condition in the view in Protect - Virtualization - Virtual machines.It behaves the same in 11.40 and 11.42.Am I doing something wrong? Or is this a known issue?Regards,Lubos

Hi,is it possible to create a report where i can see that my backups are consistent?In Nagios, we already check the jobs for success or failure.RegardsDennis

Hi,Has anyone experienced issues with the schedule for the ArchiveLog_standby subclient not running on schedule even though it is assigned to a Plan?From what we can see is that this behaviour occurs when database maintenance occurred. There are no failures logged, it just does not run.To resolve it you temporarily change the backup plan to something else and revert, which “enables” the backup again. Cheers. 

cvfwd.log from CS displays below message.ERROR: Client connection to ed*wb**** failed on ***t00*: Can't unambiguously route connection to ed*wb**** because there are multiple tunnels from different instances of CVFWD pretending to be ed*wb**** I have uninstalled the CV client and reinstalled but still no go. Not sure what else to check. Why system thinks that there are multiple tunnels? CS and MA running on Windows, and client is running on Linux.

Hi Commvault Team,We are looking at migration scenario’s, where will be moving our Commserve and standby-commserve to another hosted environment (we are moving into AWS).I have observed that some of our SQL clients have been migrated into AWS by making us of what is referred to as an MGN agent.This agent is basically a replication agent, and it has been successfully replicating SQL databases.So this got me thinking - would this be suitable for a Commvault commserve migration, because at the end of the day it’s SQL-based, and the replication side of things could save a lot of time with the migration into AWS.Obviously, we need to keep an eye on supportability, but I just throught I would throw this scenario out there as it may be worth further discussion.So, if anyone has used a volume-based replication to assist with a Commserve migration, then it would be good to hear of your experience in doing so.Thanks 

I have configured a Hadoop backup in Commvault. The scan phase completes successfully and files are being detected correctly.However, before the backup starts, the job fails with the following error:"Unable to get index server information for client [120]"Because of this, the backup never starts. I have waited for a long time, but no events or additional logs are being generated.Environment details:Hadoop client installed with required packagesMediaAgents are already configuredCommunication services appear to be running fineHas anyone faced this issue before? Any suggestions on what to check or how to resolve it would be really helpful.

Hi all.In PostgreSQL 17 incremental backups have been introduced, is this supported by Commvault? https://pgdash.io/blog/incremental-backup-in-postgresql-17.html Thanks-Anders
