Self-Hosted Q&A

Hi everyone, I have a question regarding Storage Accelerator for Dell Data Domain Boost Client libraries and the client-direct backup and restore functionality.According to the official documentation, clients can back up and restore data directly to and from Data Domain without routing the data through a remote MediaAgent. However, the documentation also states that "Deduplication and Index Cache operation would continue to be processed by the MediaAgent."So, Ccould the Index Cache operations be handled by the client instead, allowing client-direct backup and restore jobs to continue even when the MediaAgent is offline?More specifically, does Commvault Storage Accelerator for Data Domain support completing backup and restore operations while the associated MediaAgent is offline, or is the MediaAgent still required for these operations to complete successfully, despite the client-direct data transfer?I couldn't find any explicit clarification on this scenario in the official Commvault d

Hi everyone,We are exploring the possibility of backing up Hyper-V VMs directly to Dell Data Domain using DD Boost, without routing the backup data through a MediaAgent.The official documentation states that "Storage Accelerator is supported. You need to install Storage Accelerator and Storage Accelerator Add-on package on the clients." https://documentation.commvault.com/11.46/software/accelerating_backups_to_data_domain_boost_client_library.html However, it is unclear whether this functionality is supported for Hyper-V backups at the hypervisor level.Can anyone confirm whether Storage Accelerator supports client-direct backups of Hyper-V VMs to Dell Data Domain using DD Boost in Commvault 11.44? Are there any specific prerequisites or limitations?Thanks in advance for your help!Nikos

Hi everyone,I understand that installing the VSA role on a Hyper-V cluster node is the recommended approach, according to the Commvault documentation.: https://documentation.commvault.com/11.46/software/hyper_v_system_requirements.htmlHowever, for a POC we are planning to run at a customer site, we would prefer not to make any changes to the existing Hyper-V cluster nodes at this stage.So, is it mandatory to install the Hyper-V VSA role on a Hyper-V host, or is it supported to install it on an existing Commvault MediaAgent or another Windows server outside the cluster, without the Hyper-V role installed, and use it to back up the cluster VMs?Has anyone implemented this configuration or can confirm whether it is supported? Thanks in advance for your feedback!Nikos

Upgrade to Commvault v11.44.25I have a Commserver/Metrics Reporting server in one box.  I have upgraded from v11.36.123 to v11.44 25after upgrading, when I generate a CommCell console report from my jumpbox which happens to have the CommCell console installed I get anerror code 404 on the report generatedRunning the CommCell console report inside the Commserver is no issue. Reports generated but in Commserver it presents it as a folder path rather than http/sAlso the report gets generated both ways as I can see the html file generated in the < Commvault install folder>/Reports/CommcellConsoleReportAny advice is appreciatedIt appears the upgrade changes a few things 

Hi Team, i tried to do some reseach but can not find any explenation what the  Microsoft 365  - Exchange Online - Stats Status do or what they reflect. Sometimes the Stats status is up to two days in the past  

Hello! Could you please answer the following question. For the cloud storage Commvault has published list of S3-Compatible Object Storage Vendors: https://documentation.commvault.com/11.40/software/supported_s3_compatible_object_storage_vendors.html How do you think are there any risks to use some S3 vendors not mentioned in the list? May be technical issues? Or we will lose support? For example, Leviia (https://www.leviia.com/en/object-storage/) states that it is “Compatible with the S3 API and major tools like Veeam, Acronis, Bacula, Commvault, Atempo, Cyberduck, QNAP, Synology, and more.  But it is not in the Commvault supported vendor list. Please share your opinion. Thank you in advance!

This in on firefox​​​​​​This is on Chromium browser.Hello everybody,We have been noticing that there are error differences based on the browser.This happend after MR update 11.44.25do others see the same? 

Hi everyone,First of all, I have to say that Threat Scan in 11.44+ feels like a completely different product compared to 11.40. The improvements are significant, and the addition of VM workloads to the Threat Scan capabilities is a really nice enhancement. While going through the 11.44 documentation, I came across the following:“For Windows VM workloads, set up a Windows Threat Scan server.”“For Linux VM workloads, set up a Linux Threat Scan server.”Commvault Threat Scan Requirements My question is regarding whether this OS-specific requirement applies only to VM workloads, or also to File System workloads.For example, if an environment contains both Windows and Linux File System workloads, can we use a Windows Threat Scan server to scan both, or would we need separate Windows and Linux Threat Scan servers?In other words, is the Windows/Linux Threat Scan server distinction specifically related to the way VM disks/filesystems are mounted and accessed during VM Threat Scan, or does the s

Hi everyone,While testing with available integration options in the ExaGrid interface, I noticed that Commvault supports only SMB / NFS, whereas Veeam offers the ExaGrid Data Mover and Veritas NetBackup supports OST.Why does Commvault not offer a comparable native integration for ExaGrid? Does relying on SMB / NFS introduce any performance limitations or reduced functionality compared to these dedicated integrations?I would appreciate some technical clarification on whether this is an architectural choice or a limitation of the current integration.Best regards,Nikos

Hi All, i found some informations regarding gateway but my enviroment was not available.  So we are using network gateway for customer agent based backup. Actually when we are installing an agent like sql or active directory we are putting the gateway ip adress during the installation into the commserve field. So the client is regstored to the gateway. Thats fine for now. Actually we are in the situation to add more gateway servers because the enviroment is growing up.  We are working with groups and firewall rules over the groups. No we have 2 Questions: What happend with the traffic if we add an second gateway into the group ?Is commvault managening the rounting over both automaticly ? If yes wich rules are used to put the traffic over node 1 instead of node 2 ? How is commvault acting with restores over the gateway ? as written before we registerd all clients over the first gateway. If we now implemnt a second or third one and the first one is crashed is the client communication sti

I recently configured a new Storage Pool that uses AWS Glacier Instant Retrieval as the storage target, and noticed today that it has been automatically included in the DDB Verification schedules.Documentation suggests that cloud-based storage libraries should not be automatically included in the DDB Verification schedules. Has there been a change to this behaviour? Does this happen for anyone else?

Hello Team, I am looking for an API that lists the clients within a Client Computer Group, any one has any idea ? Best Regards.

Hi all. I’m planning to upgrade from 11.32 to 11.40/11.42.Many of my agents (Oracle, MSSQL, file) and virtual machines are old installations and are still running index version 1. What will happen when I upgrade to 11.40/11.42, will they continue to use index version 1 or will they be auto “upgraded” to index version 2, or is this still a manual process so I can upgrade the index when I find fit? Cheers-Anders

all,I am configuring M365 mailbox backups.I have created an Office 365 Plan and set “Retain deleted items for 2555 days”I then created a Backup Plan with Primary to Disk for 365 days and synchronous AUX to Tape for 2555.Am I correct in saying that all mailbox backups from now with be Incremental and it ignores the Backup Plan retention and keeps all mail for 2555 days on Disk & Tape ! Also, is there a way to run a once off Full backup ? Currently on 11.36 Thanks

Hi everyone,With the current cybersecurity landscape, especially in the AI era where vulnerabilities and security threats are evolving rapidly, I’m interested to see how frequently other Commvault admins are updating their environments, particularly given the increasing number of security vulnerabilities and CVEs affecting software in general and Commvault. (https://documentation.commvault.com/securityadvisories/)So, how frequently noways do you normally perform a Maintenance Release update in your  customer-managed / self-hosted environments? In some cases, especially with complex Commvault environments involving multiple sites and components, a Maintenance Release upgrade can take several hours to complete and requires careful planning. Because of this, performing an update every month may not always be practical.It would be interesting to see what update frequency everyone is currently following. Best regards,Nikos

Hello,We are currently investigating whether Commvault SQL Server Agent supports connecting to Microsoft SQL Server using TLS with TDS 8.0 and Strict Encryption.Our environment is configured according to Microsoft's guidance for SQL Server strict encryption:SQL Server is configured with a valid trusted certificate. TDS 8.0 is enabled. Strict Encryption is enabled. Connections using SQL Server Management Studio (SSMS) work successfully. Connections using PowerShell also work successfully.Reference: Connect to SQL Server with strict encryptionWhat we would like to know is:Does Commvault SQL Server Agent support connections using TDS 8.0? Does Commvault support Strict Encryption in the same way as SSMS and modern Microsoft SQL drivers? Which SQL client/driver version is used by Commvault when connecting to protected SQL Server instances? Is there any Commvault-specific configuration required to enable encrypted SQL Agent connections? Has anyone successfully protected SQL Servers that are

Our Web Server has the Microsoft 365 apps version of Outlook installed to facilitate email previews and PST exports.Recently, there were issues with exporting to PST, exports would work sometimes but not consistently. What appears to have fixed this issue is disabling auto-updates and then downgrading to 20228.20190 by running:cd %ProgramFiles%\Common Files\Microsoft Shared\ClickToRun\            OfficeC2RClient.exe /update user updatetoversion=16.0.20228.20190 Now I’m running into an issue previewing emails in Compliance Search, which is also sporadic. The Error says 'Preview not available'. I did a test and when just using the default wildcard search, I selected an email, and saw the preview. I then performed a search, selected the SAME email, and it said 'Preview Not Available. Is this also Outlook related? What version of Outlook are people running?

I want to extend the retention of jobs that ran on a specific date (September 25) for a specific client. If I select the jobs and click Retain, will I be able to perform a complete restore? Will the dependent jobs also be retained?What is the best way to do this?

Hi everyone,Our CommServe is a VMware VM with 32 GB RAM, but lately memory utilization is consistently around 90% as the environment grows. We have multiple VMware, Azure, AWS, OCI, LiveSync and Microsoft 365 environments, although the total number of VMs is not particularly high.SQL Server Maximum Server Memory is already configured at ~16 GB, so SQL is not consuming all available memory.  Would it be necessary to increase the CommServe all the way to 64 GB RAM, or would a lower intermediate value be sufficient to provide additional headroom?Since it is a VMware VM, we can increase RAM independently without necessarily increasing vCPU. CPU utilization is currently not a concern.What would you consider the best approach in this situation?Best regards,Nikos

We are using a self-hosted Commvault environment. Backup history reports show only about one backup cycle (roughly 14 days), even after testing 90- and 365-day retention periods. Older job history is unavailable, which prevents us from producing complete monthly backup reports.We understand that the older “Days to keep the successful backup job histories” setting is no longer available in current versions. We have opened a case with Commvault Support, but have not yet found a clear explanation or supported workaround.Has anyone else experienced this in a recent Commvault release? What is the supported way to retain successful backup job history for reporting after the older control was removed? Please include your Commvault version and any confirmed resolution.

Hi,How to find backup of deleted VM (in VMware) in Command Center? I cannot find it under search or Protection section. The only way is to find the job when this VM was still there but it’s not always that easy.Is there any setting that make decomissioned VMs searchable? As always it was a lot easier to find it in classic Commcell Console - I just find it under vcenter group. Commvault 11.40.

Hi All,I am observing random backup failures of different DB2 databases.All backups are started from DB2 via Command Line (Native Application Interface)The error is below:Error Code: [82:226]Description: Failed to send data to <MediaAgent>: Unable to set incremental storage policy. Jobs are running for storage policy.Source: <ClientName>, Process: DB2SBT There is no Incremental Storage policy configured to the Primary SP. The DB2 instance is configured to use the same SP for Data Backup , CLI Backup, Log Backup. Is this a case of contention when log backups are included in the db2 backup command issues by the DBA?Would a separate storage policy (backup plan) resolve the behaviour? Thanks.Ignes 

We have a primary copy which uses a deduplicated WORM enabled cloud storage pool as a target.Therefore we have frequent sealing of the DDB so the data can be aged and block references are cleaned up.I just recently discovered a client which for some reason had not started a synthetic full backup for two months despite being assigned to a plan where a synthetic full is configured.Because of that a whole DDB generation is now blocked from aging because of the cycle dependency.Is there an option to fix these kind of situations afterwards?I was thinking about a synthetic full backup which only uses incrementals up to a user defined time so the cycle stays short.As we are currently still on 11.40: I also read that there are improvements in data aging on WORM enabled pools which would enable pruning on job level rather than a whole DDB.Would this change already prevent my current situation in advance?From my understanding the DDB would still stay but only the blocks referenced by this one cl
