Hello, Teams,I am looking for someone who can share the offline documentation file for the 2022E (11.28) version. Since this version has reached end-of-life / support termination, it is currently difficult to access or review the related documentation. Additionally, all existing links for 2022E (11.28) are currently being redirected to version 11.46, making it hard to find the older references. If anyone happens to possess this legacy offlinedocs file and is willing to share it, I would greatly appreciate your help. Thank you in advance! 

We will eventually upgrade everything to 11.36.114 but what needs this update in order to resolve these vulnerabilities?Is it just the CommServe/WebServer?The Resolution does not state what needs to be updated.“ResolutionSoftware customers upgrade to resolved maintenance release.”https://documentation.commvault.com/upcoming-security-advisories/?id=CV_2026_07_5 https://documentation.commvault.com/upcoming-security-advisories/?id=CV_2026_07_8 https://documentation.commvault.com/upcoming-security-advisories/?id=CV_2026_07_9  Thanks

Where can I start downloading the Security Advisories CV_2026_07_5, CV_2026_07_8, and CV_2026_07_8? Thank you Arturo. 

Dear Team,I apologize for the inconvenience, but I was wondering if you could assist me with the following question.On August 1, 2026, I completed the Commvault Cloud Professional course to obtain the certification. However, it appears that the certificate has not yet been issued. I noticed that my previous certificates were generated immediately, so I was wondering if this delay is normal.I would appreciate it if you could provide me with more information about the status of my certificate or let me know if any further action is required on my part.Thank you in advance for your assistance. I look forward to your response.Kind regards,

Hi,Can someone clarify the Instant Clone or “Optimize for table level restore” features?I have multiple SQL Servers. DB admins ask me about possibility to restore single tables instead of whole databases (some of them are huge like 10+ TB).So now I’m testing this on my playground but I’m not sure I get how it works.Creating recovery point / instant clone attach new database to selected instance and on low-level this is VSS snapshot mounted directly from my Commvault disk library to the proxy server. So there is no real data on server - it’s just on my commvault library. Is that correct?Proxy server have to be the server when I have target instance.I can’t restore tables directly to the source database. I can only restore tables to some another databases. So what is the point of this feature?I saw that enabling this cause backup by only 1 stream. Is that true?

Hi all!I would like to discuss following situation. We are unable to override retention under plan. After turning on the option on “Override restrictions” to give permission to “Allow this plan can be overridden” than select changing the value to “Override optional/required and clicking OK we see no real changes performed.Is it possible that this setting is somewhere blocked or overwritten by another settings?

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:I would like to to know if the RPO and RTO data shown in the reports (https://cloud.commvault.com/commandcenter/#/softwareStore/10370Command Center) from Command Center are generated based in real data (I mean, based on true recovery times from the customer) or are calculated using AI or other ways.  I will appreciate more details and if someone has experience with this report, and also if the report was useful.Thanks,Paul

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

Hello,I have an HSX storage increased a lot from June to JulyThe storage is a destination for:primary copies secondary copies from another HSX secondary copy for cloud copyWhat is the best way to determine what caused this growth?I tried multiple report but I didn’t find any cause.the capacity license is still the same between June and JulyThanks !

I’m asking because the document in version 11.28 has been deleted. Before upgrading Commvault from version 11.28 to 40, I would like to upgrade the Windows version of the Commserve server to 2022. - After DR backup, format the entire existing Commserve server, then install Windows 2022 - DR recovery after installing version 11.28 of Commserve - Upgrade to 11.40 We plan to proceed with the work in this order.Is it possible to use version 11.28 of Commserve in Windows 2022?

Hello,Does anyone know if you can search the chat history on the Arlie website for specific terms?Thanks and regards,Thomas

We currently have a self-hosted Commvault environment running version 11.36.The CommServe and MediaAgent are installed on the same physical Windows server. The same server also hosts the existing MediaAgent components, including the DDB, Index Cache, Disk Libraries, Mount Paths, Data Paths.The customer’s main requirements are:Minimum operational risk Minimum downtime No unnecessary CommServe name or IP updates on the clients The existing physical server must remain in service as the MediaAgent after the separationOur planned approach is to first upgrade the existing combined CommServe/MediaAgent server from 11.36 to the latest approved 11.40 Maintenance Release.The upgrade and the separation will be performed as two separate changes, with a stabilization and validation period between them.Planned Final ArchitectureNew virtual server:CommServe only Receives the original CommServe hostname Receives the original CommServe IP addressExisting physical server:Remains as the MediaAgent Receiv

Just wanted to validate this...I’ve been chatting with Arlie and trying to get a proper “list of steps” to add a new mount point (in an existing library) to media agent “A” and then to share that with Media agent “B”. All Media Agents are Windows. It seems the steps (not all from Arlie) are:Media Agent A: Add storage and mount drive (say L:\). Format Disk as GPT, and 64KB allocation. Media Agent A: “Share” L:\… using a service account as “browse/read/write”. The share is now like “\\A\sharename” Media agent B: Map that Share as UNC (“\\A\sharename”) as drive L:\, using the same service account. I presume also set it to “auto connect at sign-in” so the mount point does not go away on reboot. In Java console, choose storage library → Add Mount Path. Choose media agent A and drive L:\, Pick mount path and choose “Share” with Media Agent B and make it read/write. Looks like I need to input the service account/credentials here too. Additionally, I may need to select “Transport type: Regular

Is there a Commvault requirement for Active Directory Delegation allowed?

Hi Commvault Community,We are backing up Proxmox Virtual Machines using Commvault.During the backup process, we observe that a snapshot is created on the Proxmox VM storage. The snapshot appears to consume storage space approximately equal to the VM disk size.For example:VM Disk Size: [300 GB] Proxmox Storage Type: [LVM-thin / ZFS / Ceph / NFS / iSCSI / Other] Commvault Access Node: Physical Server  Backup Type: Full / Incremental Storage Backend: [SAN/NAS/Local Storage]During the Commvault backup, the Proxmox snapshot is created on the same storage where the VM disk resides. We would like to understand:Is it expected behavior for the Proxmox snapshot created during a Commvault backup to consume storage close to the provisioned VM disk size? Does Commvault use a standard Proxmox snapshot or another snapshot mechanism? Is there a way to configure the snapshot to use a different storage location? Does Commvault support storage-level snapshots for Proxmox? What is the recommended configur

NetApp is currently selling the successor to the ASA (SAN Only), the ASAr2, at an attractive price. Basically, it is a system from the ONTAP family, like the FAS or AFF systems. Unfortunately, the API has changed considerably, and Commvault does not yet support the ASAr2 API. I’ve heard that integration is being worked on. Is there a timeline for this?We have a few projects where Commvault (new customer) and NetApp would be a good combination.

   We are in the unfortunate process of migrating from VMware to Hyper-V.   We are in mid migration and I am finding that the snapshots are taking longer and longer.   Normally snaps are about 15 to 30 min.   Now they are taking over 5 hours for a quiesced  snapshot.  After the snapshot is done, the Backup Copy runs quickly.   During the Snapshot job, I see lots of log messages about CHyperVInfo2::RunParallelVMSnapshotTask() - No available thread found for creating software snapshot of virtual machine XXXXXXXX.   I can not find any setting for the number of threads that Commvault will use to talk to Hyper-V.   I have had a support call open for a bit but not felling like it is making any progress.   This feels like it should be a 101 type question.    Does anyone else have delays with their Hyper-V snapshots?

I got the following error when backup a vm:Error code: [19:2601]Description: The job is pending because all access nodes to launch the job are overloaded.Source: cms01109c1us02, Process: JobManagerI have no idea what the error mean. I run the backup gateway on my Windows to backup a remote VMware virtual machine.

I have a customer running 11.40 and Commvault now has the combo tiers for cloud storage configured by default. My question resides in which tier the bucket should be created. The customer had previously created a bucket in AWS (this may come into play later) that was used to create a Cloud Library in Commvault using the AWS Glacier Deep Archive tier. When examining the data in the bucket, we can see the CHUNK data is written to Glacier Deep Archive however, the index metadata is showing under Glacier Instant Retrieval. This seems wrong to me.I have read that Commvault will apply an Amazon storage class header to every upload API call and then writes the data to the bucket, which is part of what is allowing the CHUNK data to be written to one tier with the index metadata to another tier. I’m starting to believe that the storage class header only is being applied to the CHUNK data and the metadata is using whichever storage tier the AWS S3 bucket was created with. Documentation doesn’t m

We are running into this wired issue infra stack is vmware 7, vmware 8, 2 instances of Commvault one with vm proxies used for VMWARE 7 another one is HSX with HSX nodes for VMWARE 8.  Datastore is on pure storage.  We are in transit and evenrutally migrate to HSX  This is happening on both the environments V7 and V8 (separate cv instances) The issue we run into is that when there are open snapshots; the Intellisnap backup randomly goes into hung state; where in it gets stuck during the phase(pre hardware snapshot phase) where VMWARE snapshots are taken and deleted and never proceeds into taking the storage snapshot; as a result the next morning there are open snapshots on all the VMs for that job during production hours which I then manually cull using a powershell script.  What I don’t understand is how does manual deletion works (using a script) when Commvault support says they are getting timeout in the logs when trying to delete the snapshot and that could be the issue.    RemoveSn

Hi all,  I had a question. Could not find it with a search, so maybe someone can help me out. Does CommVault support Virtual Trusted Platform Module (vTPM)?I know Rubrik does not support it yet.  Best Regard

We use VMWARE and use lots of SQL AGS.  We backup the SQL databases at the AG level however I am wondering what would be the best way to recover incase of a cyber event.   The plan I have is to take an initial snapshot all the VMs after installing SQL server on a VM and then use SQL and MSDB databases backups; and every time a server is patched take a full file system backup of the OS and location where system databases are stored.  SQL Agent would continue to protect the user databases  When a system fails completely > Restore from initial VM level backup  >  Restore file and folders via the agent based backups > Restore the databases via the DB backups Any other ideas...  SQL team dont want vms to be snapped regularly

Hi all,just wondering if anyone can help me. I’ve noticed on our Hyper-V hosts then when a backup is triggered in CommVault the system event log on the hosts are flooded with Disk and partmgr warnings for specific disks.I’m just wondering if this is normal behaviour or something we need to look in to? For context, these hosts are running Windows Server 2019, are MediaAgents for all our VMs and we are running CommVault version 11.36.102.The disks presented to the cluster are CSVs and are presented via iSCSI from our NetApp.I cant see that its causing any hard to the backups as they are completing successfully. The Vms and hosts also appear to be fine - but not sure what could be causing these warning or how to remediate them.
