Self-Hosted Q&A

Hello,We are experiencing a challenge with Commvault and PostgreSQL in a clustered environment and would like to ask if there is a supported or recommended approach.Environment PostgreSQL cluster with 1 Master and 3 Standby nodes Automatic failover managed by Patroni Commvault PostgreSQL agent is configured at the cluster level Current Behavior Commvault is able to detect failover events correctly. However, when the Master role changes, Commvault does not automatically prioritize the new Master node for backups. After a failover, we must manually move the new Master node to the first position in the cluster client configuration. QuestionIs there: A native Commvault feature, or A supported best practice that allows Commvault to automatically switch backup operations to the active PostgreSQL Master node after failover, without requiring manual reordering of cluster nodes? 

Hi - we have been backing up RDS postgres exports fine for a long time with version 14We are upgrading to version 16 but the postgresql agent seems to be missing some library files?The job error is:PostgreSQL Database: [~Loading libpq.so library failed. Please check if required libpq.so file exists in Postgres Lib directory~] Data Backup Failed.<br/>Source: aws-cvpxy-lnx-105, Process: PostGresIfindLooking on our proxy node I can see version 16 & 17 are missing the required file: $ find / -name "libpq.so*" 2>/dev/null/opt/commvault/CVCloudAddOns/PostgreSQL/14/lib/libpq.so.5-cent7/opt/commvault/CVCloudAddOns/PostgreSQL/14/lib/libpq.so.5-rhel9/opt/commvault/CVCloudAddOns/PostgreSQL/14/lib/libpq.so.5-rhel8/opt/commvault/CVCloudAddOns/PostgreSQL/14/lib/libpq.so/opt/commvault/CVCloudAddOns/PostgreSQL/14/lib/libpq.so.5/opt/commvault/CVCloudAddOns/PostgreSQL/15/lib/libpq.so.5-rhel8/opt/commvault/CVCloudAddOns/PostgreSQL/15/lib/libpq.so.5-al2023/opt/commvault/CVCloudAddOns/PostgreS

Administrative shares are enabled on the MediaAgent [cvault-cs.xxxx.xxx.xx] which could lead to potential security exploits, please review and take necessary steps. We just updated our Commvault software from Commvault Platform Release 2022E (11.28) to Commvault Platform Release 2023E (11.32.73) and we got this event at the commcell console. cvault-cs.xxxx.xxx.xx is our WindowsServer 2016 Datacenter commserve. This server is also used for backups of some VMware virtual machines, but there are no Disk Libraries/Mount Paths configured on it.    I read the information on the page MediaAgent - Windows Administrative Shares and I didn't feel very comfortable with it.  

So we have 4 new beefy media agents all identical with multiple SSD drives in each. We host multiple DDB’s on these in a 4 way grid. Details below for 2 of the DDBs.DDB117:MA01 - partition 1 - 3.77TB. 280,012,213 unique blocks, 800us Q&I timeMA02 - partition 2 - 3.75TB, 280,013,171 unique blocks, 656us Q&I timeMA03 - partition 3 - 3.68TB, 280,000,417 unique blocks, 682us Q&I timeMA04 - partition 4 - 1.71TB, 279,998,959 unique blocks, 86us Q&I time DDB118: (Same hardware)MA01 - partition 1 - 3.77TB, 316,416,711 unique blocks, 198us Q&I timeMA02 - partition 2 - 3.75TB, 316,456,547 unique blocks, 176us Q&I timeMA03 - partition 3 - 3.68TB, 316,508,932 unique blocks, 181us Q&I timeMA04 - partition 4 - 1.71TB, 314,526,253 unique blocks, 85us Q&I time Any ideas on why MA04 shows much lower Q&I times than MA01/02/03 in the same DDB? Also, why would DDB117 have such higher Q&I times than DDB118? Thanks.

Literally - So did I miss some release notes that editing reports is no longer a thing? I have more than one CommCell doing this and I only noticed it when our backup summary reports suddently turned to “garbage” with essentially no content.11.40.34thanksI see I am late to the discussion in the Report builder thread. You guys have no idea how frustrating this is. OR, maybe you do by the looks of that other thread?

It has been a while since i last read anything about WORM (Storage Lock) in Commvault and wanted to make sure I`m not misunderstanding or missing anything. My general understanding is that once WORM Storage Lock is configured and retention criteria is met, DDB is sealed. Once DDB is sealed nothing else is written to that DDB.New DDB is created and as per Arlie confirmation, the next job regardless of what the schedule policy may start (lets say an Incremental) that job gets automatically converted to Full Job so the baseline is estabilished. No issue until here unless Im missing something. The above statement used to be in the documentation (not sure if Im just not finding it or it was rephrased) but I simple cant find.Instead when looking at the documentation for WORM: https://documentation.commvault.com/2023e/commcell-console/recommendations_for_worm_storage_01.html  it says "Add the ForceFullOnWORMDDBSeal additional setting to convert the next backup to synthetic full backup after s

 Hi All. We have upgraded from 11.32 to 11.42.90 and after the upgrade the “install windows update” workflow is not working anymore, it gives the below error: Anyone knows why this is happening? Thanks-Anders  

Dear Team,We would like to know how to raise a support ticket for a general query that is not related to any backup failure.We attempted to create a ticket; however, the portal requires the Job ID and Error Code fields to be filled in, which are not available for general queries or configuration-related questions.Could you please advise on the correct procedure for raising a ticket in such cases?Thank you for your assistance.

Hi,I'm curious about your standards and strategies for schedules/schedules policies names (I'm not using plans). I saw this topic: What is your naming convention for schedule policies? | Community but maybe someone has fresh idea.We have VMs, DBs, FS and more. We have about 80 schedules. For a long time we were using something like: DC1-VM-I_I_I_I_I_F_N-21:00 which means: Location, VMs, Mon-Fri Incremental, Saturday Full, Sunday none, 9 PM another example: MSSQL-N_SF_N_SF_N_F_N-21:00-LOGS_4H - I think it's clear (SF - Synthetic Fulls, makes no sense here but it’s just example) But in reality, including DC name doesn't make much sense. There was also no good way to include the incremental backup time if it was different from the full backup time. And it turned out to be better to keep logs in separate schedule policy because it's easier to resue.Now I'm thinking about something like: VM / Inc Daily / Full Sat 21:00 MSSQL / SFull Tue, Thu / Full Sat 21:00 MSSQL / Logs 4h I think it's

We've been using CommVault for several years and have consistently been able to perform backups and restores without any issues. Recently, however, I received a request to restore a file located on a .vhdx drive.To retrieve the file, I attempted to use the Guest Files and Folders restore option, which I have successfully used in the past. When I select View Content, the system begins loading the data but then fails and displays the following error message:We are currently running on CommVault version 11.36.102 (We recently upgraded CommVault from 11.36.80 because of this issue and we thought a fix had been implemented in .84 - but this might be different to what we thought)Has anyone encountered this issue before or can suggest any troubleshooting steps?Thanks in advance.

Hello Dear AWS Team,Did you have plan the support of TAG in AURORA POSTGRESQL  ? AWS tag is available for many worlkioad, is there unknow limitation to do not have them on AURORA ?Thx

Our Commvault disk library has Storage Compliance Lock enabled. The retention setting is 7 days and 1 cycle. How can we delete the final backups of servers that have been decommissioned and will no longer be backed up? Will these backups occupy space in my disk library forever? IS there a way do delete the jobs ?

Hi all. Is it possible to backup PostgreSQL via a Windows cluster? The scenario is, that a team wants to install PostgreSQL on two Windows servers running a Windows cluster with shared disks, like you do with MSSQL. They want to put the log and data on a shared drive that runs on the active server and this drive can fail over to the passive node.  Is this scenario even possible to backup or is only possible with the PostgreSQL cluster client (pseudo-client) with a master and a standby server? Regards-Anders

What is the best practice when it comes to the number of buckets to create when using  Cloud Library using S3 Netapp Storagegrid?Is there a performance gain/benefit of using more than 1 S3 Netapp Storagegrid bucket in one Cloud Library using S3. Appreciate any thoughts, suggestions or even any documentations available online which can explain the pros and cons

Hi, I want to enable hardware encryption in the copies  to the tape library. I have enabled hardware encryption from Control Panel - System - Encryption - Hardware Encryption - use hardware encryption - No Access. However when I try to enable hardware encryption in the storage policy level, the option is greyed out. Kindly advise how to enable it on the Storage Policy level. Im running Commvault 11.40 and the tape library is a Fujitsu Eternus LT40 S2 with HP Ultrium 6 tape drive.

Hello.I saw in https://documentation.commvault.com/v11/essential/changes_in_feature_release_11_24.htmlthat CBT is no longer supported.Could you please tell me if there exists a plan to re-add CBT support? Victor

I have a interesting issue.  My AUX copy streams are capping out at 180 GB/h despite having multiple 10 GB WAN links.  I see this issue on a Storage Policy that has dedupe and compression disabled.(due to large unique data being backed up).   Does anyone by chance have a storage policy with no dedupe or compression?   I am really curious to know what speeds you are seeing on your AUX copy streams.   I feel like these should be able to go faster, but having a hard time convincing support that there is something in CV that is restricting it.We have set the nNumPipelineBuffers set to 900 already.  Our Dedupe AUX copies run amazing since there are so many streams for it to work with. 

Hi All, we would like to build our own montoring for Commvault over the rest api. My Question now is regarding the commserve failover. We are running 2 Comsmerve in 2 Datacenters with the build in commserve failover. Now when we use rest api we need to connect to the comsmerve but when the failover planed or unplaned occures the rest api commands run into nirvana.  Do you have an idear or an solution what we can to to run the api commands againts both ? 

I am planning an infrastructure refresh where I need to retire an existing MediaAgent and migrate its FC-attached tape library to a newly deployed Commvault HyperScale Edge node.My main focus is ensuring data path consistency, avoiding any library deconfiguration, and maintaining restore capabilities. The planned high-level workflow is: Re-zone the FC tape library to the new HyperScale Edge node. Validate OS-level hardware detection on the Edge node. Use Expert Storage Configuration to perform Exhaustive Detection, adding the new Edge MA to the library while keeping the existing configuration intact. Execute "Change Data Path" on the relevant Storage Policy Copies to point to the new Edge MA. Perform standard MediaAgent Retirement on the old node. I am looking for technical validation of this workflow. Specifically: Are there any HyperScale Edge-specific prerequisites or limitations regarding direct-attached or FC-switched tape libraries? What are the known issues regarding e

Hi, I have a hpe vme essentials cluster with 3 nodes, I trying to configure this in commvault so I can do a test backup of a vm that is running on that cluster.we are running 11.40 I’am using following document https://documentation.commvault.com/11.40/software/configuring_backups_for_hpe_morpheus_vm_essentials_vms.htmlBut I don’t understand how to create and use the access node?I don’t have the access node tile under Manage-infrastructure to add a new one? 

Hi, I need to do this once again at a customer,I have already done this in the past but one point in the documentation I note down in 11.20 and it’s the same thing in 11.24 ! It is not clear see the highlighted RED? Source Computer Stop all running jobs on the CommServe, or wait for the jobs to complete. Disable all CommCell activities. From the CommCell Browser, right-click the CommServe node and then click Properties. On the Activity Control tab, clear all the check boxes, except for the Enable All Job Activity check box. This prevents new jobs from starting, except for disaster recovery operations, which you need to perform later in this procedure. Click OK. Take note of all the disk libraries configured on the CommServe computer. Copy the content of index cache folder located in the following location to another accessible location. C:\Program Files\CommVault\ContentStore\IndexCache If a File System agent is installed, copy the job results folder to another loc
