Incremental Backup Converted to Full (7.5TB+) following Synthetic Full Completion Problem DescriptionA recurring issue has been identified where incremental backup jobs significantly increase in size (bloating from ~1.5GB to 7.5TB+) specifically after a Synthetic Full backup is performed. In the most recent instance, the backup remained in a "Running" status for over 10 days. While the job continues to progress slowly due to limited bandwidth between the Cloud source and the on-premises Media Agent, the root cause is a logic failure in the backup chain.Technical Analysis Automatic Job Conversion: Commvault automatically converts an incremental backup to a full backup if it cannot establish a valid baseline or if the previous cycle did not close correctly.Cycle Disruption: A backup cycle starts with a Full/Synthetic Full and ends before the next Full. If the Synthetic Full (DASH Full) fails to properly sync its metadata index or deduplication signatures due to network latency, the subse

Hi,  We got an error message on snapshot when we tried to backup a vm with a passthrough disk. We use xcp-ng as hypervisor (XenServer).

Hi All, Our costumer ask, what is the basic encryption Commvault used on another word we not select on specific chipper?

Hi,The maximum certificate lifetime is going down:From today until March 15, 2026, the maximum lifetime for a TLS certificate is 398 days. As of March 15, 2026, the maximum lifetime for a TLS certificate will be 200 days. As of March 15, 2027, the maximum lifetime for a TLS certificate will be 100 days. As of March 15, 2029, the maximum lifetime for a TLS certificate will be 47 days.Certificates for the Command Center (Tomcat web server) must be manually renewed and updated.Does CV have a recommended procedure to tackle this in future or should everyone find their own solution?/Piippu

Hello Commvault Community, We have this situation:There are MS SQL servers that have transaction logs backup during the day. Full backups are made only outside working hours. Sometimes, however, it happens that during the day, for some reason (the logs show that communication with the media agent was interrupted), a broken chain is made and the transaction logs backup is converted to full.Unfortunately, we can't do full house during the day, because it overloads the source servers. What we tried to do:1. Uncheck "convert" in the subclient properties - it did nothing, the backup was still converting.2. Do a "full data management" subclient blackout window for these servers within business hours. The workaround for blackout windows should work in theory, but if the conversion takes place, the job is still process in the JobController as "transcational log" and not full (although in reality it is already full). This is probably why the blackout window does not cover this job.The question

Hi folks, I want to ask, what is your SQL restore throughputs for large DBs.We have a 8.4TB database that takes around 18hrs to restore with average throughput around 478GB/hr.Wondering if this can be improved without introducing IntelliSnap.Network is not a bottleneck. SQL server is hosted on all flash array and the backup target is HSX. Cheers,Marcin

Hi,I’m testing backup of M365. I’ve setup Commvault instance 11.40.34 on Windows.I’ve added Exchange Online, OneDrive for Business - no problem.But when I’m trying to add Sharepoint Online app (throught Protect → Office 365 → Sharepoint Online - Configure now) then app is added, but it’s not Sharepoint but Exchange.I’ve setup separate applications for all apps with proper permissions according to the documentation.I just did everything similar to adding Exchange or OneDrive, tried few times with no luck. Any ideas?

Hi All, short question :) We have nutanix ahv vms with quest os windows 11 and tmp active. We are running cv 11.40.10 when we try to run vsa snaphsot we are getting the error vm not found. Do you know if this constellation is supported ? 

Hi All,I’m hoping for some guidance from those who have completed this step of the deployment (Complete the Guided Setup for Active Directory) I want to give the service account least privileged access to the domain as I am not comfortable with giving the service account full domain admin rights as it has been suggested by the deployment team.Has anyone got a break down of steps to achieve the above in Active directory? from what I've seen looks like we need to perform some of the required permissions within ADSI Edit?Any guidance would be great especially from those who have implemented this successfully.

The M365 admin center reports my OneDrive as having 2.8M files consuming 8.1TB of space.But when I go into Commvault I see numbers that are totally different. In Commvault I see either 1) the latest backup had 3.2M active and 0.7M Inactive for a total of 3.9M files or 2) all backups with 6.6M Active and 2.0M inactive for a total of 8.6M files.Likewise, the disk space used is reported as either 1) the latest backup with 3.4TB Active and 1.6TB Inactive for a total of 5.0TB or 2) 9.6TB Active and 4.0TB inactive for a total of 13.6TB.Is there any way to drill down into Commvault to figure out why the numbers – particularly the “latest backup” file counts – are so different from what is reported by Microsoft?

Hi Experts, I have an old setup running in Commvault version 11.16 and I am planning to upgrade to 11.32. Could you please help me to get the details how can I achive without interrupt the services ?

Hi Team,I would like to understand how IntelliSnap backups work and the detailed backup workflow, step by step.Could someone please explain this in detail? Your help is much appreciated.Thank you in advance!

If Install the 2 Independent commcell is it possible later to set-up this as a live sync?

Is anyone currently testing the new feature of restoring Exchange messages to a Blob storage? https://documentation.commvault.com/11.42/software/restore_mailboxes_to_azure_blob_storage_account.html. Have you been able to restore to a PST that is larger then 1GB? Are you locking the blob network to public IP only? Just looking to start a conversation on this.  Hector

Hi all. How would the procedure be, to do a Linux OS refresh from Rocky Linux to RHEL? The servers have local OS, ddb and index disks, and the MA’s have block storage mounted disks for the library.The hardware need to be reused, so I just want to reinstall OS, but keep DDB, index, library data, server name and IP, so that the server can continue operations after the Linux OS refresh.. Any suggestions on how to do this and any recommendations appreciated. Regards-Anders

Hi,Since I upgraded the CS to 11.36.83 I wasn’t able to connect with MFA option to web console and JAVA.Before the upgrade it works fine and nothing has been changed with the users and groups.I’m also tried to upgrade to 11.36.87 but still no working, when I’m canceling the MFA option we can login with no problem. Any ideas?Thanks 

Hi,I was wondering how people are scheduling backups. (for example file system backups)Do you only run incrementals and Synthetic fulls? Or do you sometimes run a “real” full?For example, 1 “real” full a month, a daily incremental and a weekly synthetic full.I’ve always heard never to “only” use incrementals and synthetic fulls, and to slip in a “real” full backup once in a while. What would be the reasoning behind it?Looking forward to hear your feedback.

Hello!Considering an HSX environment.How does the data aging process compare to the DDB space reclamation?Sometime I only see space being reclaimed after a DDB space reclamation job.Regards,Pedro

Hi all,I need to move the CS DB to another location as I didn't follow the best practices for the LV size and mixed it with other stuff on the same volume. For Windows, I could solve everything with my own admin account and MSSMS.However, I need to do this now on the Linux environment and I'm afraid of changing the sa password to allow me connecting to the system remotely and use MSSMS GUI.What happens if I change the sa account password? Can later I force an operation via Commcell console, so Commvault will ask me for the new one?For example, on Linux I can easily do this:stop sql server service/opt/mssql/bin/mssql-conf set-sa-passwordstart sql server serviceUntil here, fine. What about ensuring the Commvault knows the new pwd?The reason is that to perform the change of CS DB location I need to detatch the databases, move the mdf files and attach them again.Is there any other way to do it on Linux environment?Thanks in advance.

Hi all,One of my students asked me if SQL Analytics databases can be backed up as a subclient for Microsoft SQL server. I saw that it is possible in Azure SQL but I couldn't find anything in the “normal” SQL server. Can anybody help? Thanks in advance!

Hi Vaulters, In order to implement a Vault site which will contain one MediaAgent in it, we wanted to restrict the communication of this MediaAgent to only the CS + MAs in Prod site and make connection only be established through the Vault site. To make things even securised, we wanted to use a dedicated port for the Vault MA unstead of the defaults 8400/8403. Seems this can be achived through One-Way network topology while setting : Vault MA → Prod CS/MAs.But not sure about the customized port to be used, as from OS/Network perspective only the custom port will be allowed between the Vault MA and Prod CS/MAs. Should the custom port be set in the below screenshot during topology creation or set as an additional setting in the Vault MA (nCVDPORT) or both ? How to let CV know that the communication will only be established by the Vault MA and use a defined port ?  This is a bit confusing.Thanks in advance. 

Hi,I am encountering an issue with VSA backups on a Nutanix AHV cluster.The Scenario: I ran a manual Full Backup for a specific VM. The job status is "Completed". Immediately after the job finished, I tried to browse and restore a vDisk (scsi-1). The file appears in the index, but when clicking restore, I get the error: "Cannot Restore since there is no data available" The Anomaly: Restoring the same VM from the scheduled nightly backup works perfectly. The issue seems specific to this fresh manual job.Environment: Commvault VSA for Nutanix AHV. Disks are standard vDisks (not Volume Groups / iSCSI Guest). Proxy has full access to the container (verified by the successful nightly restore). Question: Is there a known Indexing Commit latency specifically for AHV that prevents immediate restores right after job completion? Or is this likely a CRT/Snapshot lookup failure on the Nutanix CVM side during the manual run?Thanks.

Hi,There is a way to disable the Multi-person authorization forever instead of 24 hours?Thanks
