Hi.I am planning for the migration of TSM (Spectrum Project) backup data to Commvault.I have a couple of questions around the configuration:1. For backup data from Linux TSM clients, a Linux Commvault Proxy/Staging client is required?2. Same as above for Windows TSM clients, then a Windows Commvault Proxy/Staging client is required?3. Do these staging clients need the Web Server and Index Store package installed or can this run centrally from the CommServe?Please add anything that should be considered.  Thanks.Ignes 

Dear Commvault Team,Good day. I hope this message finds you well.We kindly request your assistance in identifying the path or location where the following procedure should be executed:Recommended Action (Test First in Non-Production):To address this, you can configure an additional setting on the VSA proxy to disable snapshot verification. This may help bypass snapshot failures and allow the backup to complete.Please follow these steps in a test environment:Add the following additional setting on the VSA Proxy:The key is not added to the library "bVerifySnapshotCreationAllowed", so it won't appear in the search. However, you can add it manually.Name: bVerifySnapshotCreationAllowed Category: VirtualServer Type: Integer Value: 0Restart Commvault services on the VSA proxy after a

Hi Commvault users, Regarding backing up VSA’s (proxy servers) that are used for VM image backups. Do you recommend backing them up ? if so Daily, weekly etc.Being just proxy servers I’m guessing there is no real need to back them up if you can build a new one quickly. Any advice is welcomed.  Kind RegardsTerry   

Dear Team, We are planning to upgrade to a new CommCell server with an updated Commvault license.The current CommServe is a physical server running on Windows Server 2012, functioning as both the CommServe (CS) and Media Agent (MA) and additionally the commvault license End of support.As part of the upgrade: We will deploy a new virtual machine with the latest Windows OS to serve as a dedicated CommServe. A new physical server running Oracle Linux OS will be provisioned as the Media Agent. Kindly advise us on the best practices for deploying and upgrading the backup infrastructure in this scenario.Thank you for your support. Regards,Mani D 

I have 2 FREL’s in my environment and we use this FREL as VSA proxies as well to share the load between other 2 VSA proxies. After upgrading this FREL’s to 11.28.107, we see VM backups fails with the error “The virtual machine [] did not pass the disk size validation. If this issue persists, please contact your vendor support hotline”.I have VCenter level configuration for VM backups and I have 7-8 Subclient and each subclient have 15-20 VM’s in it.When the backup get triggers for this subclient as per schedule, at least 6-7 VM’s fails with this disk size validation issue. Once this VM’s fails, I re trigger them one by one and backup completes without and issue.Can someone tell me, what can be done to resolve this issue completely.

Heyho,a customer is using lotus.In 2017, the backup was set up for this and we have a full backup in the transaction log subclient.Now it is not possible to trigger a full backup of the subclient and the command centre constantly reports that the subclient needs a full backup.Is there a way to deactivate the message for the subclient in the Command Centre? 

Hello all,I’m looking into support for CEPH, namely the block access (RDB) because we’re considering replacing the current SAN arrays with CEPH distributed storage and backup is of course a big segment of it.But I cannot find much information on integration with CEPH, e.g. support for IntelliSnap feature which is well supported for NetApp/Pure etc, nor which DB agents are supported with CEPH as block storage. Has anyone played around with this idea? Are there any internal reports or (POC) reviews that could shed some light on this?Thanks in advance! Regards,Igor

Anyone else experiencing the problem with Office 365 when trying to run a restore where the options were recently changed? Exchange restore I can only restore the items to the original mailbox or I need to pick another mailbox. I no longer have the option to restore to PST file. SharePoint, I can only restore to the same site or I need to pick another site. The option to restore to disk is no longer available and the same goes for OneDrive. I don’t like the limited options now for restoring Office 365 files. 

We're encountering a recurring issue related to CBT (Changed Block Tracking) in our VMware environment with Commvault (version 11.36).After incremental backups fail or complete with CBT-related warnings, any subsequent restore of the affected VMs results in machines that fail to boot — only a black screen with a blinking cursor is shown after powering them on.In addition, Guest File Restores are no longer possible for these VMs. Attempting to browse the file system results in the following error:Failed to get items for volume The original VMs continue to run and restart without any issues.The problem affects multiple servers, not just a single system.The issue is resolved after performing a full backup — restores (including guest file restores) then work as expected again.Example error mess

When backing up from Oracle RAC, Commvault selects an available server by default.Is it possible to select a specific server for backup? 

Hi Everyone,I’ve noticed a significant increase in the size of DDB over the past few days. About three days ago, each partition of the DDB was approximately 115 GB, and as of today, all four partitions under the same engine have grown to 145 GB each.Could you please help me understand the potential reasons for this growth? What areas should I check, and are there any recommended troubleshooting steps to investigate. 

Hi, I am trying to restore a vmdk and attach it to the VM. Was able to do it successfully on the web console.  I also downloaded the EQUIVALENT API.  How do I use the “EQUIVALENT API” for future restores  without using the web console ?I (preferably) want to use REST, but I couldn’t find the endpoint to run this restore. Does anybody know what the endpoint is ? Thanks in adavance!

Hi,I am facing issue with accessing commvault command center every time I am getting “Please wait while our servers start up. This may take a few minutes.” message on the web portal.RegardsAbhishek 

We recently loaded up a brand new Commserv. Upon configuring On-Prem Exchange Mailbox backups there was a cleanup job policy created that was configured and enabled. On first run after the first mailbox run (Close to 4700 mailboxes) the job deleted about 1.8 million e-mails from exchange based on the settings of the job which appears to have picked1 day past our retention date to clean up everything. Our retention date is 90 days so the job used 91 days.  Has anybody else even seen where the cleanup job automatically enables when an exchange plan is created and uses defaults?

We are planning to migrate from VMware to Hyper-V platform. In VMware we have the option to choose transport mode on the sub-client level but in Hyper-V i don’t see this option. We have approx. 1000 VMs to backup after migration. In VMware we have kept dedicated VSA proxies to associate with particular ESX host for Hot Add backups. Could we do similar set up for Hyper-V, instead of using Hyper-V node as a proxy use bunch of VMs acting as VSA proxy which will be associated to particular Hyper-V node for Hot Add backups.

What permissions will a user need to run the Active Directory comparison option in Metallic?

I am going to have to do a migration from RHeL to Rocky Linux.There has been documentation for this sporadically but ultimately this gets removed and I have had confirmation that this will be possible with similar process to UEFI.I have emailed the migration support but so far not had a response. I need to start planning this in shortly so if anyone has any experience that would be great

Hello, I have Commserve LiveSync setup that is running version 11.32.83 on SQL 2016 SP3 on WS 2019.I want to upgrade this setup to 11.36 version which requires SQL 2022.Do I need to do some multi-step upgrade process? For example an SQL upgrade first and then commserve. Or I need to proceed as usually and SQL will be upgraded automatically? Have anyone real-life experience?Thank you in advance!

Hi Team, I observed that HistoryDB size got increased which is around 25+ GB. What might be the cause and will it impact the performance and what troubleshooting steps we can take to address the issue.

Hi Community, I am trying to figure out how to add the discovered SQL Servers to Subclient content using the API. Does anyone have any experience in how to do this? From what I could get my hands on, the API reference did not really specify this. Let me know. Thanks,Daniel
