Hi All, maybe you can help us.  During an human error the option: DDB horizontal scaling threshold number of subclients per DDB 1  was set to 1. This cause last night  DDB [xyz] crossed number of subclients threshold hence created a new DDB [xyz] for adding new Subclients.  Now we have 2 DDBs   So what happen is that all new subclients will be run against the ID:44 and all old one deduplicated against ID:41  This happend also for another engine.  The new created id is actually empty. Sealing did not help. also we tried: qoperation agedata -delbystoreid -sid 44 ft Q_DATA_LOG Actually running support case does also have no idear if and how can this ddb can be deleted.  The problem is that we dont have enoug space in metallic cloud for running in baseline. thanks for your help

Hello, I have a DASH copy from the Prod site to the DR site. The DDUP partition on the DR site appears to be running out of space, so the Aux copy has been stopped. What should I do to resume the auxiliary copy? I can’t add more space.Thanks 

If i understand correctly Changed Block Tracking is not supported when taking VM backups in a Citrix environment?Backups for Citrix Xen (commvault.com) When a virtual machine disk for a Xen virtual machine is backed up, the entire disk is read for allocated blocks, for both full and incremental backups. Can anyone confirm? I was thinking that CBT will greatly improve the backup speed. Thank you!

Hello Commvault Community,We had a problem with "point in time" replication between two physical Windows servers. A group that has been defined in Command Center is not visible in CommCell Console (you can see the RP store, but nothing in the Data Replication monitor).Recovery data (latest recovery) works without problems - the backup is on the second volume, but in the "point in time" I can't overwrite checkpoint on the target volume. There is no way to select another client to save a copy of the volume (can’t select the resource).  How to do it correctly? What needs to be done to make it possible to select a resource?Regards,Michał

 Hi All,We are backing up SQL server as an AWS EC2 instance. There was change were done in which SQL server EC2 instance replaced with new EC2 instance with same name and data. From our end we released the Commvault license and when Commvault was installed onto the new EC2 instance by default client for with we have released the license should get Commvault license and should be showing up. But this don’t happen and new client with same name was created. Please help me to know why new client with same name was created.From my end we missed that the new EC2 server will be created with new OS. Old EC2 has 2012 and new has 2016.Request you to please help me to fix the issue. 

We had to configure backup for new NDMP servers.

HelloLooking for anyone who has used Commvault together with Snapvault and would like to know some best practices. I have used both Intellisnap and snapvault in the past but not together.Here is the setup (which was setup before I joined the company). The environment consists of 2 primary AFF and one seconday FAS for the snapvault. All backups are handled with snapshots, so no data is actually sent to the MA or a library. Commvault is only the orchestrator for snapvault and provides vCenter integration through VSA proxy.Plans are in use, and ESX datastores are added to the plansBackup workflow: VSA Proxy tells vCenter to do vmware application consistent snapshot, then the Array MA send commands to Netapp array to create snapshot. Vcenter then removes vm-snapshot and Commvault considers the backup job complete.Backup copy is disabled on the storage policy, otherwise it created a snapclone from the snapshot and mounted it as a datastore and backed up the VM’s through nbd to the MA and di

Hello!Could you say pleas, if is it possible to export/import some backup from commvault? So that I could use it later without source commvault, by importing backup it to different commvault environment or using some native restore tools of restored application. 

Hi,I have a question regarding the Graph API permissions for the Azure application that needs to be configured.It’s related to this topic:Azure Application API Permissions for M365 Services | Community (commvault.com) Why is it necessary for Commvault to retrieve user list and licenses? And assign the application Directory.Read.All permission?  During my testing, I managed to run a backup from a SharePoint Online site without this permission assigned. However, when attempting to restore back to the SharePoint Online site, it fails. In the Azure Storage account, I can see some items appearing under the container during the restore, but they are deleted after a short while. In the log from the Commvault application server I see the following error message:Error decrypting password.  Is this error related to missing API permission? Or is it something else? The storage account is set up as descripted in documentation.  

I have a customer that has some types of  auxiliary copies to cloud one is virtual machines and the second is logs He want to see how much virtual machines backup to cloud and what is the retention of the auxiliary copy to cloud He does not want to see all the clients in the report.  

Hi Group, I’m hoping someone can help me out. We are trying to develop a script that can be ran on a client which will use a find command for specific files to create a list to be backed up and restored on another client using CLI or the cvc command. We are new to Commvault and were able to do this with TSM’s dsmc command.Any help or examples would be much appreciated. Thank you

hello,I need to restore windows vm’s from hyper-v to vcenter vmware . I use this article https://documentation.commvault.com/v11/essential/114427_converting_to_vmware.htmlThe restore complete successfully without errors. But when the server is booting up it direct to something like recover mode. At the end of this article it’s written  For converted Windows VMs, disks might be offline. You can bring the disks online manually. How do I Bring disk system online?       

Is an option within CommVault to update the description or note fields on the source host platform (VMWare/Azure) when a backup is performed/successful through alert notifications ?

Hello allWe don’t currently back up our entire VM estate due to licence/cost limitations. We’re on a capacity licence and nearly at the limit so it’s buying time. I’ve been asked to work out how much capacity licence we would need to add to be able to back up all our VMs (from this we can somewhat factor in growth rates). Does Commvault provide a report or sizing tool to be able to see this easily? I can see what we’re currently using licence wise, and I can see all my unprotected (excluded) VMs under virtualization, but not how to easily put these together. if I did have to do this manually I’d be looking at the VM size wouldn’t I for the front end size?Would my reseller have a sizing tool maybe? Or can mere mortals get that too?!Thanks for any and all help.

I am preparing a ddb for retirement. There are no jobs associated with it and I have run a space reclamation at the highest level with Clean Orphan data set. Why am I still seeing values in Total Number Of Unique Blocks?  

Stuck trying to get SAML SSO sorted in a test environment before moving into Prod.  Followed the procedure at Using Active Directory Federation Services as Your Identity Provider (commvault.com) and SSO for Command Center or Web Console works fine on every other machine bar the CommServe box hosting the webserver. It just prompts the authentication box 2 times before defaulting to non SSO.Non SSO logins via domain creds work fine. CommCell browser DOES work fine using SSO on the web server box! It’s just browser access. Using LiveSync and failing over to the secondary CommServe results in the problem moving with web access restored on the previous primary server. The problem then afflicts the secondary (now primary. Tried running “in private” browser sessions and clearing cache with no result. What logs will monitor the transactions with the iDP to help me troubleshoot the issue. The Webserver logs show nothing.

Hi,I am looking for confirmation that we can use Windows 2022 as an Azure Media Agent. From books on line I get the following, but this doc was written in 2021 and I can’t find a later version. https://documentation.commvault.com/2022e/expert/assets/pdf/public-cloud-architecture-guide-for-microsoft-azure11-25.pdf Books has Windows 2022 in this url https://documentation.commvault.com/2022e/expert/2822_mediaagent_system_requirements.htmlRunning v11.28Thanks

I have a storage policy for one shot backups to Tape.The tape robot being used doesn’t have a lot of free tapes, and our other robot has a lot more free tapes.So I am trying to make a secondary copy to transfer all that data to the other DC and to then promote the secondary copy to primary.The transfer of data works, but the option to promote is greyed out.When trying with the promotetoprimary.xml, it gives me this error:A copy Dependent on a Global Secondary Copy Policy cannot be promoted to a Primary Copy. I don’t understand what this means.I also don’t know how to resolve this.
