Self-Hosted Q&A

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

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

Hello,We are planning an operating system upgrade for a physical Commvault All-in-One server and would like to hear from anyone who has completed a similar upgrade.Current configuration:Physical Cisco UCS C240 M5 server Windows Server 2016 Standard Commvault 11.40.67 Non-clustered CommServe The same server hosts the CommServe, MediaAgent, Web Server/Command Center and Workflow Engine components Local DDBs and disk-library mount paths are also hosted on this server The customer does not want to split the CommServe and MediaAgent roles or migrate them to new hardwareThe planned target is an in-place upgrade directly from Windows Server 2016 to Windows Server 2025.Microsoft supports the direct upgrade path for a non-clustered server, and Commvault 11.40 supports Windows Server 2025. However, the exact procedure for an All-in-One server is not fully clear, especially because the same machine hosts both the CommServe and MediaAgent roles.I would appreciate feedback on the following:Has anyo

Good Day,We have two Microsoft Office 365 Index Servers configured in a load-balanced setup.The index disk on Index Server A became full, so I ran the Load Balance Index Server workflow. After the workflow completed, the index data was moved/copied from Index Server A to Index Server B.Since then, we have been experiencing issues accessing the Index Server and index-related operations are no longer functioning correctly.Could you please clarify:Why are the Microsoft Office 365 backup indexes not automatically distributed across both Index Servers when load balancing is configured? What is the recommended method to rebuild or recover the indexes after running the Load Balance Index Server workflow? How can we restore normal Index Server operation in this scenario?We are running on SP 11.40.67 Error:  Exchange index stats failed for subclient [4107] with message [Exception of type 'Commvault.InfoRetrieval.SearchServerException' was thrown.] Unknown error, Webserver failed to process Idx

I am currently questioning our AuxCopy to tape performance and want to get some input on how to identify the bottleneck.We have multiple plans which all have two copies to tape. One is synchronous and one is selective.Each of the two is consolidated onto another Global Secondary Copy Policy.The storage target are six LTO9 drives with a mixed LTO8 and LTO9 media inventory.The source for the copy is a NetApp StorageGRID S3 backed storage pool with deduplication connected on a 100G fiber network.We have two Media Agents which are both connected to all LTO drives and the NetApp (same VLAN).Looking at the reported speed of the drives in Commvault I get around 130MB/s all of the time.I could confirm this looking at SFP speeds on the FC switch which also stay around this value with rare peaks to around 200MB/s.What I tested already to look for the bottleneck:- only run one AuxCopy Job- run AuxCopy when no other jobs where running- validate drive > 300MB/s throughput with LTO8 media- differ

According to the documentation for the disk caching for log backups feature, the CommServe computer does not need to run frequent backup jobs throughout the day. Instead, log files are backed up at the desired frequency using native backup utilities, cached to a mount point on the MediaAgent, and made available for database restores. The Scheduler then runs at the interval defined by the "Use disk cache for log backups and commit every" setting to commit the cached data.I understand that the cache resides on the backup storage associated with the primary copy of the backup plan and that Commvault handles this automatically when caching is enabled.However, the documentation does not specify the directory path where these logs are saved. Could you please clarify where exactly the logs are stored on the MediaAgent during the dump phase? 

Hi Commvault community, We are currently configuring Microsoft Teams user chat backups through Commvault and would like to clarify the current requirements regarding the Microsoft Teams Export APIs.According to Microsoft documentation, starting August 25, 2025, Teams APIs are no longer metered and no billing configuration is required:https://learn.microsoft.com/en-us/graph/teams-licensesThe Microsoft documentation also states that the Teams Export APIs are no longer subject to metered billing.However, in Commvault Command Center we still have the option “Enable this app to use paid Export APIs”, and the current Commvault AI guidance still instructs us to enable this option for Teams user chat backups.Could someone please confirm the current Commvault behavior/requirement?Specifically:Is enabling “Enable this app to use paid Export APIs” still required for Teams user chat backups? Does enabling this option currently result in any Microsoft/Azure API charges? Is the option still required

Hi All, i have an problem with my nutanix ahv vsa backup.  I git the message: Failed    Virtual machine [xyz] was not found. Please verify that the virtual machine still exists and that the host is in the connected state. If the virtual machine does not exist remove it from the subclient. If the virtual machine does exist reselect the virtual machine and re-add it to the subclient content.     When i do an browse i found ths maschines. Also under prism central the vms are up and running.  I created an test subclient with this vms but doesnt help.  Do you have an idear ?

Hi guys,I’m currently evaluating / planning the migration from a Windows CommServe to a Linux CommServe.We are using a Fujitsu ETERNUS CS8000 virtual tape library with VJUK (generic SCSI library) emulation as Tape backend.The Workflow (Prefetch Tapes for Restore) provided by Commvault to prefetch media, that have been migrated from cache, is no longer working on Linux CommServe.The Command ManualPrefetchTapes.exe, that is called by the workflow on Windows, cannot be found in the Linux distribution.Can someone tell me where to get it ?Or is there a newer version of the prefetch workflow available, that does no longer use the external command to initiate the prefetch ?Currently running on V11.40.59BRKlaus

Hi Commvault experts! Two things I'd like to have confirmed: Firstly, am I right that laptop backup plan is basically incremental forever? As far as I understand it, the client only ever sends changes and full backups are created as synthetic fulls on the storage side, so the endpoint never uploads a full backup overthe network. Is that correct? Secondly, I'm not clear on how retention works once a secondary copy is added. In the laptop plan you set deleted item retention and file versions, but the storage policy behind the plan has its own copies with their own retention settings. So which one actually applies - does the plan drive retention for both copies, or does the plan only cover the primary copy while the secondary copy is governed by the storage policy copy settings?Related: is the auxiliary copy schedule independent of the plan's RPO, or is it tied to it in some way?Thanks!

Hi there!In the retention settings for laptop plans you can set how long deleted items are kept, but what if there is a specific file that needs to be removed from the backups completely, so the retention rule doesn't apply to it at all?The use case could be a GDPR "right to be forgotten" request - the file is deleted from the laptop, but it also has to disappear from the backups.I found references to Erase Data by Browsing, but the documentation I came across is old and describes the CommCell Console. Is this available for laptop clients/plans, and where would I find it in Command Center? Does it need a separate license?Cheers!

I have a few questions regarding the documentation for testing IOPS for both the DDB disk (https://documentation.commvault.com/2024e/commcell-console/testing_iops_of_deduplication_database_disk_on_windows.html) and the Disk Library (https://documentation.commvault.com/2024e/commcell-console/testing_iops_for_disk_library_mount_path_with_iometer.html)The documentation states to run the IOMeter test “on the complete raw disk”, and “IOMeter allows allows physical disks to be selected only when there are no volumes on the disk”. Does this mean that the disk should not be formatted before running the IOMeter test? For the Disk Library, I am mounting a LUN from a SAN to the MediaAgent that is about 48 TB. What is the best way to test IOPS for this? I am guessing I will need to set the Maximum Disk Size, otherwise creating that huge iobw.tst file would take ages. Is the CVDiskPerf tool the preferred method testing Disk Library (like the above)? https://documentation.commvault.com/2024e/commcel

Hi there!In a laptop plan I need to back up a specific folder that sits directly in the user profile, for example:C:\Users\<username>\ProjectsThe machines can have more than one user profile, and I want the folder backed up for each of them.I noticed the default content uses tokens like \%Desktop% and \%Documents%, so there is clearly a mechanism for resolving the user profile path. But those look like predefined tokens for known folders and I couldn't find one that would let me append my own subfolder, something like \%UserProfile%\Projects.Is there a token for this, or is a wildcard path like C:\Users\*\Projects the way to go? Or does the plan content have to be defined differently for this kind of case?Thank you in advance for your contributions!

Hi everyone,I’m looking for a tool or report that can perform a more comprehensive assessment of an existing CommCell environment.I’m already familiar with the Health Report, Security Assessment and Configuration Reports, but I’m looking for something more comprehensive that can assess the overall configuration and best practices of the environment in one place.For example, I’d like to assess things such as encryption configuration, Live Sync, security settings, storage and deduplication configuration, DR readiness, backup configuration, potential configuration issues, etc., and ideally get recommendations or findings for areas that should be reviewed or improved.Is there any Commvault tool, report, workflow or Store application that provides this kind of comprehensive CommCell assessment?Something similar in concept to VMware’s Health Analyzer would be exactly what I’m looking for. Any recommendations would be appreciated!Best regards,Nikos
