Getting below error while trying guest file restore for a linux VM through access node in Commvault v11.40:“Browse failed due to error while mounting virtual machine: No valid node is available to perform a guest file restore of the choosen VM.” VM backup can be successful but browse/restore fails.Has anyone faced this kind of error befre? and what can we do to resolve this?

I have a VM LiveSync setup, CommServe is Windows 19 running 11.28 and old version of SQL. From the online documentation and the SQL upgrade recommendations, and supported version migration for Windows to Linux. It looks like the hardware refresh and staying on Windows (enabled in REGEDIT) to 11.40 is the best approach, this will allow for the Windows migration to Linux by Dec-2027 approach with supported workflows. Are there any caveats - or a link to VMs (LiveSync) hardware refresh steps, CommServe installed with C-Name, so expecting a straightforward import on to Windows 25 and SQL 22.It seems because of the old version of CV, stops me running SQL in place upgrades or Windows to Linux migrations. Everything seems to be 11.32. or 11.36 options only, so to avoid multiple convoluted paths, just create 2 x new VM’s, enable CV on Windows and download CV 11.40.x import the CV DB’s during install. Shutdown the old LiveSync pair and fire up the new VM’s importing the DB files during the CV i

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

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

Hi All,I'm looking for technical resources and experience in integrating Commvault with Morpheus.What is the integration architecture?Is it possible to match tenant between Morpheus and Commvault? If so, how? So far, I've found only one link on the subject at Morpheus:Commvault — Morpheus Docs documentation (morpheusdata.com)In the integration section of this link, it says to add the IP or Hostname of the CommServe”, but I'm under the impression that it refers to the Web Server (in our architecture, the Web Server is not hosted on the Commserve). Thanks,Luc

Hello!Having just upgraded to 2024E, specifically 11.36.41, I notice the Active Directory agent now supports backups for GPO as documented here - Great. Changes in Commvault Platform Release 2024EHowever, the permissions required are not particularly helpful: Permissions to Back Up Group Policy Objects via PowerShell: The account must have the necessary permissions to back up GPOs using PowerShell cmdlets. By default, members of the Remote Management Users group possess these permissions. My question is, if you don’t want the account to be a member of “Remote Management Users” or admin groups, what granular permissions can be set on the account to still achieve the backup? full error:-----Currently whilst the backup is completing for AD as it always has, its now completing but with error “Failed to process group policy object”.Error Code: [28:548]Description: Failed to process group policy object. Please verify following: (1) User account configured in Active Directory connection setti

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.

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

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?

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.

We have a client sitting in a DMZ that can successfully connect to media agent 01. However, media agent 01 does not have a DDB. In the job logs we can see the scan phase for the job complete on MA01 but then it fails on the backup phase. We noticed in the logs an attempt to connect to the CVD service on media agent 02 which houses the DDB. The client does not have a path to MA02. In this situation, does commvault require the client to have comms to the DDB media agent MA02? I thought that MA01 would handle connecting to MA02 not the client. How does Commvault handle the data flow in this setup?  Thanks!

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.

!-->Hello,I’m playing around backup Azure VMs to on-prem Commvault. I setup all Azure stuff: create application, assign custom roles etc. So next step is configure access node.I deployed Commvault Cloud BYOL Access Node VM as described here: https://documentation.commvault.com/11.40/software/deploying_commvault_cloud_access_node_from_azure_marketplace.html (selected 11.36 as there is no 11.40 version on Azure).In Azure I setup network rules to open incoming connections on 22 and 8400-8403 ports from my on-premise public IP. Checked network connectivity from Commserve (telnet) on this ports - it's ok.So according to documentation next step is register node by commvaultRegistration.sh script.Entered values:client name: whatever client hostname: public IP of the Azure VM CS Name: commserve CS hostname: local IP of commserve Is CS behind firewall: yes - option 2 (CS can connect to client) Port number: 8403 HTTP proxy? noAnd here are first problems. Script is not finishing, it's just sta

Background:We have Aux copies moving data to a second location, and from that location Tapes are written. We have 2 Media Agents there, each with 1 mount point to storage (and they share the mount points).  The mount points have gotten so large we cannot allocate more space to them (a Windows 256 TB limitation).We *could* just add more mount points to add more storage but we would like to just “delete the existing mount points” from Commvault, wipe the storage, and then rebuild the mount points so we have maybe 4-5 smaller mount points per server (say 75 TB each). Then we would Aux copy all the data back to that location (which would prob. take 4-7 days). Questions:If we were to do this, would there be any “gotchas” or things to consider (we have a global DDB on this secondary Aux copied location, and several on the primary location)? I assume its not as simple as “turn off aux copies, delete mount points, wipe storage, and then reallocate storage and mount points, share the mount poin
