Hi,I configured Livesync betweeen two commserve servers. They connect to the same network without firewall enable. I run “Test Failover” test and all good without problems. Then “Mantenance Failover” all test are ok, without problem. But, when try “Maintenance Failback” the test failed.This are the steps:07/25/2025 11:45:24    Checking node [StandbySQL] is reachable...07/25/2025 11:45:24    Sending the request to make node [StandbySQL] passive...07/25/2025 11:45:11    Stopping and disabling all the services...    Done07/25/2025 11:45:51    Update firewall settings...    Done07/25/2025 11:46:15    Sending the request to make node [ActiveSQL] active...07/25/2025 11:46:15    Update firewall settings...    Done07/25/2025 11:46:15    Disabling read only CommServe mode if enabled...    Done07/25/2025 11:46:15    Update remote cache client...    Done07/25/2025 11:46:15    Running MongoDB repair utility...    Done07/25/2025 11:46:25    Enabling and starting all core services...    Done07/25/20

I have tried searching, but with search terms I keep getting looped back to topics covering snapshot backups and filters.If a VM has an agent installed, (therefore not taking VM/Snapshot backups) but is powered off in VMWare….is there a way to have it skip backing up the machine (or do something else like fail earlier, throw an alert, or something else you might suggest)? The issue is we have alot of machines where we are just not told to stop backing them up from the team that owns them, and just don’t want to reach out every time we see a job stuck in pending because it can’t be reached.  Trying to free up resources to research actual problems, and not mask actual connection issues.  We don’t want to manually disable machines that might be powered off for some temporary issue.I understand snapshot backups can filter by powered off, but these are machines that have reasons to have an agent installed and can’t utilize snapshots.running commserve v11.32.38Thanks!

Hi!As Server 2016 will go out of support anyways within the next year, I consider proceeding the upgrade before, as 2019+ support larger cluster sizes than 64 kb which should drastrically improve file system defragmentation and by that HDD performance.The “wasted” should be less of a deal, as Commvault saves data in big chunks of 1+ GB anyways. I assume that Commvault does not have trouble with the cluster size (the storage part in documentation is generally pretty “thin” regarding file systems, best practices etc.).Sidenode: You should definitely add, that partitions/drives above 64 (actually more 63.5) TiB can’t be snapshotted with VSS, nor can chkdsk do anything on those. But the main question: Is there any problems to in-place upgrade Windows Server 2016 to 2025?It would be big pain to migrate all that data (we have one machine running all services/functions) to a new (pricy!) server as long as the hardware is still supported/maintained. I’ve read and old thread that recommended do

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   

I’ve got a TrueNAS server with a bunch of CIFS shares.  I setup a Windows File System client to do the backups of the CIFS shares, using our CommCell master to do the backups.  Unfortunately, no matter what, it backups up all the same files for both Full and Incremental backups, which slows things down and screws up temp disk space usage.   So what’s the process to figure out why this is happening?  This is around 1.7Tb of data and 2+ million files, so it really slows things down. CommVault 11.36.5?  something, pretty new.  The TrueNAS is Enterprise 13.0-U6.2 release.  The Windows backup server is running Windows Server 2016 (I know, I know...)  The TrueNAS runs Samba internally to do CIFS shares.  Not sure where the disconnect is here.  Has anyone else got this working properly?  

Hi all,  We have a project to apply CIS Benchmark Level 1 settings to our Windows servers, and that includes our CV environment. I’m looking for feedback on the process. Good, bad, ugly, etc. Thanks G

I'm testing Exchange online email restore using the "Received Time" filtering option. I've set a received time of (for example) of 2019 - 2020 but I'm seeing email from as far back as 2000. has anyone else used this filtering options and what were your results. In full disclosure, I did also select the option to show deleted items but that SHOULDN'T affect the results in my window.

Hi all, I’ve been starting to look at Data Insights, and Sensitive Data Governance and went to create a test project to try it out and got the following error:Error creating EDiscoveryUser.Exception:User password doesn't follow minimum complexity requirementsIs that complexity requirement coming from CV itself?Is it looking at our domain requirements?Is this user local to CV or a domain user?Is it possible to assign a user object?Just looking to find out more about what it’s doing at this stage, thanks.G

Hello Commvault Community,We are planning to migrate to the latest Commvault version, which no longer supports V1 indexing. As we prepare for this transition, I would like to gather insights and advice from those who have already gone through this process.Questions:What are the essential steps to ensure a smooth migration from V1 to V2 indexing? What are the critical considerations to keep in mind during the migration? Are there any known issues or pitfalls that we should be aware of? What best practices can you share for managing the migration effectively?Any detailed experiences, tips, or documentation links would be greatly appreciated. Thank you in advance for your support and guidance!

Dear Team, I am planning to perform an email restore for one of the users from the Compliance Server. I noticed an option during the process—could you please explain what will happen if this option is enabled or disabled?  Regards,Mani D

We will be adding a new VMWARE Envrioment V8 to our Commvault backup; we use Intellisnap backups at the moment, however, in V8 we are using Datastore Clusters; how does that impact Intellinsnap and would the process be same Adding Storge snapshot engine to Commvault Setup Subclient and use the snap engine however, would there be impact if say due to storage DRS a VM moves from one datastore to another. I have seen with Intellisnap (Nutanix) if you have a VM in 2 Datastore it fails the whole job; yet to runinto this senario with pure but how would this work?  

Does anyone have any information from Commvault regarding CommServe support for windows server 2025?I have tested it in our lab and it seems fine. 

Hi Team,I’d like to know if there is a way to run PostgreSQL, MariaDB and MSSQL backups from scripts on the clients similarly to RMAN.I founf the Save as Script option on the Subclient, but we woud like to use our own commands (pg_dump  ${database}) and still make sure the backups are witten to HSX.ThanksFrancesco

Hi:Which is the best way to migrate from Commvault to Commvault Cloud? (Metallic) I have been told that there is not an utility to do it and that should be a restore and backup process just like as going from another software to Commvault, but I guess that a lot of customers may have the same requirement.Any thoughts will be appreciated.Best,Paul

 Hi team,Can I back up an OPENVMS v7.3-2 (AlphaServer ES47) system with CommVault? or is there a backup strategy?is it not supported? on the dopcumentation https://documentation.commvault.com/v11/expert/openvms_file_system_agent_system_requirements.html mention only HP OpenVMS 8.3, and 8.4. regards,

I have created a new subclient policy but instead of using this default subclient i created a new sublclient to take backup of only selected extensions and assigned to all 100 laptops.now when i created a schedule policy and assigned schedule policy to a laptop client group .the backup us being run for the default subclient as well as the new one which i created.i have disbabled default subclient from policy by “activity control” but still the schedule policy executes job for both and its causing lot of failures in my job and confusion during restore.raised case with support ( 250331-339) but they are not able to do anything from last 10 days. 

Hi, I’m having problems with a Commvault Oracle Data Guard configuration. I have a Data Guard pseudo-client which handles the backups for the environment which has 2 databases on 2 different hosts: dbhost01 and dbhost02. It is configured to run backups on the primary node. A few days ago a database failover happened (from dbhost01 to dbhost02), it was successful, so no issues with that, currently the primary database is on dbhost02.My problem is that since the failover the commvault backups cannot run, because it is still trying to reach the database on dbhost01 (which is shutdown). It sees that the database on dbhost02 is open, but does not even try to start the backup there.What is the correct way to configure this? The whole point of having this Data Guard configuration in Commvault is that we don’t have to modify anything in commvault when a failover/switchover happen, so I’m looking for a solution that provides this. Thank you for any tips, solutions, etc. Daniel

Hello Community, We have that configuration: File server with DFS namespaces on Windows machine.  Archive solution with Windows File System Archiving on the same machine. and time to time, DFS service is blocked by Commvault  which stopped shared files to users. According to Microsoft investigation there is a file which working in the same time and can provided that issue: E:\System Volume Information\Commvault\Data Classification\dc_001.db-journalDoes someone have that type of problem? Is possible to move somewhere that DB from Commvault site, to not stop DFS service?Regards, Michal

HelloI am planning to install a new Media Agent with DAS, this one will be Server 2022 and here is my question - should I consider ReFS for data, DDB and Index?Commvault support does not provide any 100% yes\no answer, Commvault documentation has zero information. Thoughts? 

Hi,I do partner support and sometimes I advice my customers to collect logs.I had to notice that under FR36 we currently need to collect Log files manualy often on Linux clients.sentlogs runs in an error Job Status: [Completed With Error] The client [ora] got critical error: [There is not enough disk space in the [/opt/commvault/iDataAgent/jobResults/sendLogStagingFolder]. The available free space is [6.00] GB, please make sure to have at least [10.00] GB and retry the operations.].   Failed Client(s): ora    It will take some time until customers find enough space to sadisfy the threshold. May be it make sense to reserve 10GB in the future. May be Setting the Minimum Free Space for the Job Results Directory is not the screw we should turn here.Do you have a good suggestion what we can do to make “send log files” working again until hundred of Unix machines in an CV environment have increased the “jobresults” size or have been moved ? It's annoying to have to repair the t

hi,I need help creating a backup schedule in version 11.36 using the command center.

When taking a Commvault VM Image backup it updates the VM on the vCenter with job no and last backup date which is very helpful for ensuring however is anyone aware of being able to update a VM on the vCenter with details of Agent based backups (SQL, Windows etc) appreciate any help or advice.
