Share Best Practices

I know I can’t be the only one that faces this problem and I’d like to know how other folks handle it.Requests for application backups can be fairly simple.  Backup this server, <drives, paths, server> using <agent type>.  Following <RPO/RTO policy>….Etc, Etc.But some backups can get a little to a lot more complicated, especially in high security environments.Some applications have very specific documentation about how to back them up, and more specifically, how vendors will support restoration issues if their procedures aren’t followed.  This can be especially problematic in clustered or multi server environments.  For example, I have an application I back up that runs a main application server and 4 back-end servers that run various functions.I asked the application owner if they should be backed up as a consistency group?  He had no idea what I was was talking about, but worse thought it was my responsibility to fi

Hello all,Hope you can help me with this quick question:Will CIS Hardened scripts on Commvault store work for Windows 2019 and/or 2022?I am referring to this: https://cloud.commvault.com/webconsole/softwarestore/store.do#!/96/635/20763 Thanks in advance for the answer!Sergio.

Just curious.  What is the policy where you work when it comes to applying hotfixes? Do you treat hotfixes differently than release version upgrades?I’m asking because my predecessors would apply hotfixes (if they addressed a specific issue) without really telling anyone other than maybe an immediate supervisor and an email to the engineering team (and maybe the NOC I’m not sure on that one).  They'd take a DR backup, SNAP the Commserver VM and let it fly and roll it back if there was a problem.I’m more of a formal process kinda guy.  I assume most of you will tell me, “what’s the problem?  Just follow a formal process.”, but I there will be people in my organization that will push back because of the successes of the past.  I lack the real experiences that come with issues related to applying hotfixes (if any).  Anyone have any experiences they can share?How do you folks treat hotfixes?  

Hi,Is it possible to use linux for intellisnap proxy server or should I use only windows for the proxy as the document said? Thanks 

Hi, We have setup a third isolated copy on CloudLib. On this copy we are also enabling Commvault Compliance Lock. We have Oracle backups running to our Primary Copies where we have RMAN managing the retention. As per the documented instructions we have the CV retention set to Infinite on out Oracle Plan and this works perfect as we can see the jobs aging off per the RMAN retention. The question/concern is what happens on the third copy if we set the retention to Infinite and enable Compliance Lock? We cannot risk locking the data with Infinit retention for obvious reasons.Anyone out there that have experience of this? What is best practice? Regards,Patrik 

Hi there, We are looking at possibly using a Rocky Linux based media agent, I was just wondering if there were any “Hardened Linux Commvault Media agent images for Bare Metal at all? We are currently running version 11.32, moving to 11.36 within the next couple of weeks. Have people used a linux media agents widely? and which flavours have you seen at all? TIADan Everitt

Hi, Are there any scripts available following best practice for hardening of Linux OS for Media Agents?I found this in the store: Storebut seems to be more like a report and not a proper script. Kind regards,Daniel

When creating a new cloud storage, I am asked to enter the media agent. However since I am in a tenant(company) account, I do not have access to the infra server like commserve and media agents. How can I give minimum access to the tenant so that the tenant can add the storage?

Hello. community, While I am installing CommServe, I noticed the “selection Windows packages” appears Content Extractor. I would to know more about content extractor, I have 3 questios:What is “Content Extractor”? When do I use “Content Extractor”? When i have to install it? Can you share with me links for more information?I have attached a image for your reference: Thanks.

Hello,I have a storage policy with an AuxCopy ( synchronous )  configured with the bewlo retention rules:7 days 1 CycleWeekly full - 30 DaysMonthly full - 90 Days I’m planning to create a another copy that will point to another data path to hold only the short-term retention ( 7 days 1cycle ), and to reconfigure the existing one to hold only the Weekly + Monthly full keeping the same retention days for those.How should I re-configure the exsiting copy?  Just remove the short retention rules ( 0 days 0 cycles ) and leave the extended retention rules for the weekly + monthly fulls as is ? Leave it as synchronous copy  or change it to selective ?Thanks

Hello community,we are using IntelliSnap to achieve smooth and fast backups for our Oracle clients.The integration is configured as follows: RMAN connection string points to the RMAN catalog Backup interface is set to RMAN Data restore from Commvault works perfectly “The issue”: We are unable to retrieve a list of backups from the RMAN catalog for backups performed using Commvault/IntelliSnap. This limits our DBAs, as they cannot query backup information directly without accessing the Commvault console. If we perform a regular backup copy (not a snapshot) of the database and archive logs, the RMAN catalog updates correctly and lists the backups. Question: Is this expected behavior (by design) with IntelliSnap? Are there

Hi,  We have huge amount of data to be copied to Tape for Offsite copy .We did setup the Tape library to have data backed up to Hyperscaler on commvault then to the Tape connected via Fibre. the data are in Perabytes . I look for best practice to utilize the Tape for the offsite copy. Appreciate any help on this 

Hi all,We need to apply security patches to the SQL Server used by our CommServe.We'll patch manually, without any third-party tools.I found this doc:https://documentation.commvault.com/2024e/essential/including_windows_os_and_sql_server_updates_when_installing_commvault_feature_and_maintenance_releases_01.html?_gl=1*zcnoq0*_gcl_au*NzI5MjE2NzU0LjE3NTQ1OTEyMDI.*_ga*MjAzNTA5NjMzMy4xNzU0NTE3NTM5*_ga_M2TFPKFW4N*czE3NTQ1OTEyMDMkbzEyJGcxJHQxNzU0NTkxMjM5JGoyNCRsMCRoMA..But it seems focused on upgrades, and I’m not sure if that’s the same as manually patching SQL Has anyone done this? Is it safe to patch SQL manually, or can it cause issues with Commvault?

Hello all Our Business is currently in the process of migrating our existing services hosted in a onprem data centre into the cloud hosted by a third party. As part of this migration we have a number of existing VMs which host both Oracle and SQL databases which will be migrated as is including the current IP.Our CommVault backup solution has now been configured with new media agents and associated Cloud Library & GlobalDDB. We have also started to build out plans based on the existing plans with the exception these are now using the new libraries / media agents etc.What is the best method to update the existing clients to point them at the new plans / media agents just as I’ve seen on the client properties under “Network” and “Network Summary” there are details in a file called “FwConfigLocal.txt”. This has details pointing to the old Media Agents, are we meant to manually edit this on each client after the migration to point at the new

Hello Team What are best practices for MS SQL backup and especially restore for big databases in terms of splitting DB into multiple files (SQL side)? Let’s assume we have 10 TB MS SQL database. What is better:Having 1 file for whole DB Having 10x 1 TB files Having 160x 64 GB files?And why?Let’s assume we can have 4-16 backups streams for this DB.It’s question about performance of backup/restore/DB itself, not about management and handling with files or underlying storage raid distribution/layout per DB/file. Kind regards,eMF

My bad, I misunderstood and now i can't figure out how to edit my question. We currently have 4 commserves, all very large. We use Hyperscales in all the environments. We are going to set up two more and are considering having a separate install of SQL so it can be managed by the customer apart from Commvault. I was just wondering if anyone has done this and your experience doing it that way? THx

Hi,I configured Livesync betweeen two commserve servers. They connect to the same network without firewall enable. I run “Test Failover” test and all good without problems.

I have tried searching, but with search terms I keep getting looped back to topics covering snapshot backups and filters.If a VM has an agent installed, (therefore not taking VM/Snapshot backups) but is powered off in VMWare….is there a way to have it skip backing up the machine (or do something else like fail earlier, throw an alert, or something else you might suggest)? The issue is we have alot of machines where we are just not told to stop backing them up from the team that owns them, and just don’t want to reach out every time we see a job stuck in pending because it can’t be reached.  Trying to free up resources to research actual problems, and not mask actual connection issues.  We don’t want to manually disable machines that might be powered off for some temporary issue.I understand snapshot backups can filter by powered off, but these are machines that have reasons to have an agent installed and can’t utilize snapshots.running commserve v1

Hi!As Server 2016 will go out of support anyways within the next year, I consider proceeding the upgrade before, as 2019+ support larger cluster sizes than 64 kb which should drastrically improve file system defragmentation and by that HDD performance.The “wasted” should be less of a deal, as Commvault saves data in big chunks of 1+ GB anyways. I assume that Commvault does not have trouble with the cluster size (the storage part in documentation is generally pretty “thin” regarding file systems, best practices etc.).Sidenode: You should definitely add, that partitions/drives above 64 (actually more 63.5) TiB can’t be snapshotted with VSS, nor can chkdsk do anything on those. But the main question: Is there any problems to in-place upgrade Windows Server 2016 to 2025?It would be big pain to migrate all that data (we have one machine running all services/functions) to a new (pricy!) server as long as the hardware is still support

Hi Commvault users, Regarding backing up VSA’s (proxy servers) that are used for VM image backups. Do you recommend backing them up ? if so Daily, weekly etc.Being just proxy servers I’m guessing there is no real need to back them up if you can build a new one quickly. Any advice is welcomed.  Kind RegardsTerry   

I’ve got a TrueNAS server with a bunch of CIFS shares.  I setup a Windows File System client to do the backups of the CIFS shares, using our CommCell master to do the backups.  Unfortunately, no matter what, it backups up all the same files for both Full and Incremental backups, which slows things down and screws up temp disk space usage.   So what’s the process to figure out why this is happening?  This is around 1.7Tb of data and 2+ million files, so it really slows things down. CommVault 11.36.5?  something, pretty new.  The TrueNAS is Enterprise 13.0-U6.2 release.  The Windows backup server is running Windows Server 2016 (I know, I know...)  The TrueNAS runs Samba internally to do CIFS shares.  Not sure where the disconnect is here.  Has anyone else got this working properly?  

Hi all,  We have a project to apply CIS Benchmark Level 1 settings to our Windows servers, and that includes our CV environment. I’m looking for feedback on the process. Good, bad, ugly, etc. Thanks G

I'm testing Exchange online email restore using the "Received Time" filtering option. I've set a received time of (for example) of 2019 - 2020 but I'm seeing email from as far back as 2000. has anyone else used this filtering options and what were your results. In full disclosure, I did also select the option to show deleted items but that SHOULDN'T affect the results in my window.

Hi all, I’ve been starting to look at Data Insights, and Sensitive Data Governance and went to create a test project to try it out and got the following error:Error creating EDiscoveryUser.Exception:User password doesn't follow minimum complexity requirementsIs that complexity requirement coming from CV itself?Is it looking at our domain requirements?Is this user local to CV or a domain user?Is it possible to assign a user object?Just looking to find out more about what it’s doing at this stage, thanks.G
