Storage and Deduplication

Hello Community,We recently acquired a new infrastructure that includes Commvault version 11.32.69, an HPE ProLiant DL360 physical server running Windows Server 2022, and an HPE MSL2024 library with two LTO9 drives. This infrastructure was implemented to back up a small environment consisting of SQL databases, a VMware 6.0 environment with 20 virtual machines, and some SQL Server databases.Although the initial setup seemed promising, we have encountered two significant issues that are impacting our backup operations: Excessive Cleaning Cartridge Requests (Case 250110-656) 🧹: During backups, the LTO9 drives frequently requested cleaning cartridges. This issue persisted even after HPE replaced both drives three times and after adjusting the Drive Clean parameter in the library properties to a value of 515. Low Backup Performance (Case 250110-659) 🐢: In our performance tests, w

We need to move the current CommServe environment to another server due to space issues on the current server.What are the best practices for conducting this migration? 

Hi,I am testing 11.36 version and realized Commcell Console is not installed anymore with new installations.I you need to use Commcell Console you have to request to technical support.Is there a way to configure Gridstor from Command Center? Regards, Matias

 Here is a screenshot of the current status of the ddb.   Backups are running over desired time windows with 98.27% of load being ddb lookups.   We are close to capacity currently with backup storage though this will be resolved soon.   How can we resolve the high DDB lookup % issue?DDB and job status screenshots below.   

Has anyone had any major issues after install 11.34.44?  Failed to mount disks, slow throughput, VSBKP disconnects constantly.

Hi Guys,I have disk library with 8 MPs inside and 1 of them selected /plan for decommission as i dont need it or must destroy hardware under it (mean plan for decommission as selected on MP level “disable MP for new data” + “prevent data block references for new backup” 1st mine question is why CV still, after so many years on market,  have no possibility to decomm MP. Mean here simple click on MP from GUI and then options “decomm it” which will move/spill from that MPs to other MPs in the same library all data (jobs) and  dedup data for jobs ?  And again as probably will be here such suggestion i dont want move MP to other place  as i want to get rid of it and have clean environment beside to remeber that MP called X is laying here but i real is not need :( ! But as i have not what i want i must take longer way to achieve what i want so wait till data decommiss ….here lucky if user have not INFINITIVE retention as then CV is as child “can not do anything

Hi Team,I want to understand how exactly the space reclamation job works and why do we need it when we have Data Aging. What is the Data verification and how it works in the background. Thanks.

Hi!We’ve recently moved media-agents to new servers, and i’m now in the process of “cleaning up”. And for 3 of the 4 media-agents the report showed nothing, and i could delete the mediaagent without any issue. However, for the last media-agent, it complains about “Proxy Server to Perform Intellisnap Backup Operations”, and lists a client name, a backupset name, and a subclient name.This was “correct”, because there was a subclient there with that name that was configured for intellisnap (but not in use, and had no backups). So i deleted the subclient… but even so, now several days later, when i try to delete the media-agent, the report still complains about the same “issue”. I could ofcourse just ignore the “warning” and proceed with the deletion, but i’d much prefer for the report to show that there is no association, before proceeding with the deletion.

We have doubt about Disable WORM storage lock feature.Currently we are on 11.32.59 and storage is Netapp GRID and HPE Catalyst.We are planning to enable the Storage lock feature. If in case we have to disable the WORM storage lock once enabled, we have to follow the below steps.https://support.commvault.com/Article/Details/82504 In our environment we dont have SMTP configured.What is the workaround here? Please advise.  

Currently we have our MRR Backups set to have a monthly Full set to be stored for 2557 days, which is 7 years.  This used to be the way we stored tapes but I feel that we need to change our thinking, as our system has 7 years of data and we did a full when we switched over to MRR which was uploaded.  So for our Company Policy in theory every monthly full has 7 years worth of data.  So at most I would think saving a year on the cloud is fine.  It would keep us safe from most issues unless something sits for a year without being found or triggered.  Long way to get to my question.  If I change our extended retention from 7 years to 1 year will it need to run a new Full Backup and reupload everything again or will that first backup we seeded at the start will just be there and all the other backups will just age out after they hit 1 year?  I really hope that makes sense, it does in my head.  Thanks for any info.

Hello,We have Commvault server, simpana version 11.28.68.We have situation that we want to keep the old backup whose retention expires soon. Also we disabled the schedule policy for this specific subclient.Is it recommended that we disable Data Aging for this Storage policy?If we disable Data aging for this Storage policy, backup jobs should not be deleted regardless of  exceeded retention?Best regards,Elizabeta

Hello Community,Based on CM's documentation, you can accelerate backups by installing the Storage Accelerator software on clients. https://documentation.commvault.com/11.20/accelerating_backups_to_hpe_storeonce_catalyst_storage_library.htmlQuestion: Is this functionality supported when the StoreOnce appliance is connected with Commvault via Fiber Channel?Thank you 

Looking for advice or documentation to support changes.  Running 11.28.126I need to add slower (cheaper) disk storage to my Commvault backups.   I have a DISA Cloud virtual environment and it offers 2 speeds of primary disk.   Tire 1 High Performance Tire 2 Moderate performanceTier 1 -~ all Flash/SSD disk drivesTier 2 -~ 7200 RPM Serial Attached SCSI (SAS) disk drivesMy Goal is to add the slower disk to hold about +60% of my backups.  Then the Faster disk can be used for the daily backups and quick restores and the slower disk can be used for long term storage (backups older than 7 days) and old archive restores I have a single, all in 1 Commserv/Media agent… server.   It currently has 16TB of local storage Disk attached to it in 2TB disk increments (8 storage disks). Only one storage pool.  All setup as Spill and Fill.Option A: I see in current documentation that I should use “dedicated storage pools for high-performance disks and sl

Hi I’m trying to use 1Touch restore, and I have the backup set to backup everything, and checked the system state box, but when we go and pick the backup set to restore it gives an error“System State components needed for 1Touch recovery [ Offline Files, Registery, System Protected Files ] are not available in the backups selected……….”The source is Windows 2016, with 3 hard drives, on my backup job (default backupset) in contents I have “\” and checked “Backup System State”.Using commvault version 11.32.63    platform release 2023E  Client is at same version.Anything else I need to do to get the system state backed up right? Thanks-Brian 

Hi,I am running Commvault with MSSQL, but these backups do not deduplicate; the only savings we get are from compression. None of our MSSQL backups deduplicate at all (+200 DB Clients), we made sure we did not have anything affecting deduplication, like db side encryption etc.If you run a Commvault backup, and then run another one after the previous has finished on a system with no activity, we would expect 99% dedup savings, but instead of that we have between 50% to 70% cause it is only compressing and the new compressed data has new signatures every time. Our workaround is to use VSS, that works as a file backup, The MSSQL backup with VSS enabled deduplicate with almost 99.9% savings doing the same test. VSS also comes with its own problems like slow backup performance and MSSQL with VSS is not considered best practice for Commvault.We have over 200 Commvalt clients with MSSQL, and this happens to all of them, we have all with VSS enabled

Hello.  We sent 300TB of backup jobs to AWS when we were squeezed for space.  Now that we have the additional space, what’s the best way to copy the data back down?  These jobs only exist in AWS with a long retention so I can’t just let them age naturally.  We have 3 copies for the storage policy:Primary Pure Storage Flashblade - Synchronous Copy AWS - Selective Copy; “Do not select Automatically”  (we manually choose the jobs)What are my options?Thanks!Dan 

Hello all!In our environment, we have created a temporary copies within our few storage policies - (call them copy 6 and 7). Those were tape copies. We have keep some backup there for 2 months, but it is no longed needed. We do not need those copies within those storage policies any more. But for now, even if they are no longer any backup retained on this 6-7 copy, we do have a lot of “Big Data Apps” jobs retained on those copies.We would like to delete those copies because it interferes with our “workflow” which picks jobs for copies and it's keeping to mark them to copy for 6-7 copy. (even if copy is disabled) So my question is - what exactly this Big Data Apps is? It is some kind of Index, am I correct? If those “Big Data Apps” are stored on copies 6-7 are there any dependencies for other copies, other jobs keep in other/same storage policies?Can we just delete copy 6-7 from our storage policies even

Dears,I have a question,In an organization, we plan to replace an MSL6480 (LTO8 tapes) with a new MSL6480 (LTO9 tapes) and decommission the old one once the new one is configured but the need the data on the old tapes.My question is what I need to do to make the new library read data from LTO8 and LTO9 Tapes successfully? Thanks for your support.

Hello,I want to delete a mount path after the migration. But when I try to delete it, I get error message saying:“Delettion is not possible. Reason - Storage has WORM data”Any idea what should I do?

Hello Community, I have some flow to automate. In my company we have second copy of data working as our DR solution. I would like to have possibility of change backup copy association from Storage Policy by API or QCommand to automate entire process. Please let me know which option is possible to perform in that situation. For example: Regards, Michal 

Hi Vaulters,I have a question regarding a new full linux 11.36 config done entirely using the Command Center.I recently installed a Grid of 2 Linux Media Agents with each its DA SAN FC storage. I created a disk library with 2 mount paths and 2 dedup partitions.On the properties of each mount point I can see the path of the mount point of the Media Agent that hosts the block storage but I also can see a path  “via network” from the other Media Agent. Anybody know the nature of this “network” share? Is that a dataserver-ip share? Anybody knows a way to use a good old NFS share between the 2 MA in a grid without the Java console?

We are a long term Commvault on-premise shop.  We are starting to move some thing to Azure.  So far we are backing those things up to our on-prem CV environment.   For efficiency and time, I am looking to setup a few media agents and library in Azure to run and store the backups.  I have reviewed the “Public Cloud guide for Microsoft Azure document, and based on it, I am planning to setup 2 media agents with a partitioned duplication database across them.  For the Library it looks like Azure blob object storage is the way to go.  I should be able to have both media agents access it.   Is this similar to what folks are doing?  For our on-prem we were using local storage on the media agents, and the paths were shared with each other.   This design will be a little easier to manage, but I am a little worried about the performance of blob storage vs storage local to the MA’s  I look forward to hearing from other folks with there Commvault setup and the cloud migr

Hi, We have holds configured in the storage policies to reflect backups to be retained for about 7 days, 1 cycle. Now, when I browse the CV_Magnetic folder, I still see V_## folders from years and months ago in them? shouldn't they be automatically deleted after the 7day retention period or am I just missing a configuration setting somewhere?Can old folders be deleted? Regards,Johana

I experienced slow incremental/synthetic backups due to limited throughput. I would like to understand if changing the default UNC path and indexing on the DDB will affect the backup process.
