Self-Hosted Q&A

During the installation of Commvault CommServe is it possible to:A: Use an instance of SQL NOT installed on the same server as CommServe?B: Assuming YES to above, use a clustered Always On Deployment of SQL?C: Is CommServe supported on a shared SQL instance and not an instance dedicated to CommServe?D: Do any of the above have implications on the backup of the system database?Many thanks for responses!  

Hi,Need to know from your experience if Commvault license has been expired are client backup will not run or will failed when run? Our license is about to expire soon. We cannot ensure if our renewal will close out before the expiration. thank you.

Hi,Please help me with the following questions:Let’s say I deploy Hyperscale using the reference architecture on Hitachi hardware. I need to set long term retention backups to anything but tape.Can I connect an external storage as secondary disk/cloud library to the environment? Also, what type would it be (FC luns, iSCSI luns, NAS shares/exports (NFS, CIFS), S3 buckets)? If any external storage is permitted as disk/cloud library, would it be connected to all nodes on the Hyperscale cluster, it being the one who controls writes between nodes avoiding conflicts? It being an appliance, does it have any operating system hardening besides the security features included in the software (which run with or without the appliance)? For example, intrusion prevention and detection (like avoiding root logins, avoiding running OS commands or tampering with autostart config, etc.) When upgrading the software, does it work just the same as a non

Hi,We have some physical servers which use the File Level Backups. I wonder if I just want to restore some certain files in those physical servers from tapes; what is the best practice for it? Thank you.

Hi Everyone, I’m trying to build a backup map via commserve rest-api. Does anyone what the relational data structure of the commserve of the client groups, clients, apps, storage policy, schedules and subclients is like? I want to create a report with all subclients configuration. Thanks,Regards,Juan Forero

I have a client that is kicking off DB2 backups via cron job, there is an issue with the backup and I killed it but it keeps starting again.  is this normal?What am I missing? 

Our current deployment has 4 physical MediaAgents on prem to backup to a flash array, we have an Aux Copy from the flash array to Azure which has 4 MediaAgents in Azure.  The current Aux Copy job shows Source MediaAgent as the 4 OnPremMAs and the destination as the 4 AzureMAs.  We have recently deployed an on prem S3 with an additional 4 physical MediaAgents and have added it as a Synchronous Copy similar to the Azure Aux Copy.  The on prem S3 Aux Copy job shows one physical MediaAgent as the source and destination MediaAgent.  One of the “new” MediaAgents was actually part of the line for the OnPremMAs at one point but was replace by newer hardware.  This one MediaAgent is the one that is showing as the Source and Destination MediaAgent.  This OldMA shows up on the Mount Paths for the flash array with Read/Write Access.The S3 has been configured with 4 Mount Paths, one for each new physical MediaAgents and each has been shared with each of the new

I’ve been using Commvault through the java console for years and backups are what I guess you’d call traditional GFS so even though we’re using global dedupe and synthetic fulls we’re basically running a weekly synthetic full and aux copying all backups from disk to tape each week.The change rate is really low so most weeks we’re basically coping the exact same multi-TB backup to tape as the week before.I’m wondering what people see as the pros and cons of things like server plans where it looks like it might push out the synthetic full to once every 30 days.Or maybe even stick with “manual” schedule policies but look at pushing synthetic fulls out to run a little less often.Right now I’m just thinking about this because I’m building up a new MA so it’s made me read/explore a little more - basically nothing is broken so I could just leave it as it is but I’m quite conscious that if I span up a new commcell and use the web console we probably wouldn’t end

Summary The following thread describes the potential exposure to the Apache Log4j vulnerability and steps to update Commvault software.It has been confirmed that a small subset of Commvault agents are impacted.  Update as of 1st February: Maintenance Release to bring Log4j version to 2.17.1 across Commvault software platform has been released. This release includes the upgrade of components that previously used Log4j 1.x.  Update as of 20th December: Maintenance Release including relevant hotfixes now available for Commvault software, see section “Maintenance Releases”. Please note customers who have already applied hotfixes for Log4j 2.16, do not need to install.For customers with Commvault Hyperscale X and Distributed storage, please see section new Community article here: 

Dear Members,What will be the best practice to create DB policies and schedules for MS SQL Backups. As per our standard policy Primary Copy 7 days retention period, AUX copy to DR 8 weeks and then tape backups for 1 year and 10 years. So how should we create schedules for Daily DB backups, Transaction logs backups every 4 hours. Should we keep separate storage policies for DB and logs backups or they can be on the same.Any addiditional information will be highly appreciated. Regards,AQ

Hi All,We are in the process of decommissioning the on-prem media agent server. After decommission we won’t have to backup any clients and the new server which we are going to build is for restores. The new server needs to be build in Azure.Currently we have on prem backups to disk library for 30 days retention and AUX Copy backup which runs every 60 mins to AWS Deep Archive. In order to prepare the new server for restores till date, I have done the following, but got stuck with some questions, Please assist me in completing this task.Built a new Windows Server in Azure Installed CommVault Media Agent Server with the same build as the on-prem server 11.20.85Ques : Should we move DDB of AWS to new Media Agent Server?https://documentation.commvault.com/2022e/expert/11078_move_ddb

Hi, The customer wanted to release vm socket license for esxi host. In normal condition to do so you have to make full backup of VM on other esxi host, right?What if VM and subclient does not exist anymore and retention for last backup is infinity? He can’t delete the backup. The customer was using VM backup report to check last backups on esxi. The customer had to make backup of all VM’s in environment (all subclients) to solve the case. Is that normal? Regards,Lukasz

Hello,After changing the DR Backup UNC path on CommServ to a new network shared folder, the new DR backup jobs complete without issues.Anyway on the Event Viewer there are a lot of warnings with Event code 34:59, relative to the old folders to be deleted, that cannot be accessed anymore.The messages are like: CommServeDR: Path [<OLD_PATH>\SET_NNNN] cannot be accessed. It may not exist. Otherwise, please check Share and Security settings.I believe that it’s normal because I’ve also changed the user to access the new share.These warnings are repeated every day, after the successful DR backup job.Is there a way to avoid CommServ to try to delete all the old directories forever? Best RegardsLucio

Hello Everyone,I checked the documentation but was not able to find anything related to my query.Does someone know if we can protect Microsoft PKI - Public Key Infrastructure ? I know we can cover the filesystem backups of this servers, but the point is to truncate the logs of the application somehow.Thanks. 

Latest v11.28.44.I’m backing up some Windows File iDA agents and some UNC locations to a disk library on a server that is to be retired.The old server had 12 individual volumes each presented as a mount path.We’re using Global DDB and there is about 50TB of physical storage consumed on the old library.The new server is running Server 2022 and ideally I want the disk library under a nice simple “Backups” folder on a single ReFS 64KB cluster size volume on the new MA.Whilst the volumes on the new MA are BitLocker encrypted we’d also like to use Commvault encryption.So what I think I can do is either move the existing mount points to the new hardware but I end up with 12 mount paths under the “Backups” folder or setup a new library with a single mount path and aux copy the data to it and then switch it to primary.Two questions.Which of these is the better option if I want to enable encryption on all the backup storage and wha

Hi,How to delete the stale jobs(after retention) automatically becuase the cleaning up the job consuming more time. Please helpThanks 

Hello we are replacing our backup storage and have chosen a Netapp E2860. Is there any experience here in the community with this system or a few tips that we could still consider in the configuration? LUN size, block size other features ? Kind RegardsThomas 

Hi all, I just generated two Infrastructure load reports, one for 24 hours and one for a month.While the 24 hours report is giving me a less than 30% CPU usage for most of our mediaagents, the one month report goes up to 70% CPU utilization.In particular, when comparing the last day on the ONE MONTH report with the complete 24 HOUR one, they do not match. I would expect to see an average of the 24 hour usage as the last value in the month report, but I am rather seeing the highest value in those 24 hours being reported in the last day of the month report.Is this correct? Does the one month graph reports only the highest utilization values of each day? (instead of an average of the usage through each day) please advise. Sergio 

Hello Everyone, I would like to understand if SQL AAG(has 6 nodes) can be selected as the source client while configuring a replication group from command center. My customer has a similar set up where the Pseudo AAG client is source and destination is stand alone SQL DB in the replication group. Has anyone worked on a similar configuration, please share your experience.  

Hi all This is more of a roadmap query.We have a POC that requires DB2 Backup/Recovery using Commvault. The caveat is that DB2 is hosted in the Model9 cloud infrastructure. My understanding is that this isn’t supported as yet. One of the other backup products out there is claiming they support this.Is there any available information on this from a Commvault road map?Thanks,Mauro

Hi, I’m seeing a new functionality under SharePoint Plan in the Feature release 2023 (11.30.30)but I can’t find any detail on what's been backup and what can be restored from that backup ?
