We are on 11.32.Are there any way to this or future plans to integrate this for Plan Settings?Thx in advance and Best RegardsMarcel

DDB horizontal scaling - how hash references work ?

Hello,can someone explain, how DDBs are queried, if new DDBs for a specific purpose are created ?Looking at the figures below, the VMs are leveraged among both DDBs, while only the initially used DDB has a severe amount of primary hash references.I know, that a new DDB is created and subclients are reassociated if a DDB reaches its limits (Q&I time and/or # of hashes), but I always assumed, that after the reassociation, some of the data is again identified as unique.The picture below let me assume, that old references are still honored and only new hashed are added to the currently associated DDB. If this was true, a new horizontal DDB does not automatically require additional space in the backend.  thanksKlaus

The right strategy when using HW deduplication and Object Storage

Hello, Please help me with the following question:Our primary copy will be stored in a backup appliance. Hardware deduplication will be used so we will disable Commvault’s deduplication for that copy.Our secondary copy will go to a object storage (on-premises). That storage can also deduplicate but the achievable reduction ratio is nowhere near what Commvault’s dedup can provide. So we would need to enable Commvault’s dedup for that copy.Isn’t it contradictory that CV’s dedup is disabled for primary but still needs to be enabled for secondary? what would be the right strategy for deduplication when having a backup appliance and a object storage in our backup environment? Would it be better just to use CV’s dedup and not take advantage of HW dedup? Thanks for the help!

Hi,We have a deduplication Database that it doesn’t seem to deduplicate at all and is ocupying more than we guess it should be.that DDB only backups VMs ans the deduplication ratings showed in the DDB are horrible and it caused that the library is full.   Best regards.

HSX adding CommVault Cloud MRR

Hi all,When adding CommVault Cloud (MRR) to on-prem - HSSX v3, Adding the Cloud Library only allowed a single node to be selected. Do you then have to share the Cloud Storage Pool to add the remaining HSX nodes and only then get an option to create additional DDB partitions, it seems to have changed since last time, are the partitions created when the additional nodes start to pick up backup jobs. Or do i still need to create the DDB/Cloud/P1 P2 and so on. CheersJules

WORM with backup storage appliance

Hello,Please can you help me with the following:I would like to know how does WORM work with appliances like Data Domain or StoreOnce in comparison with object storage systems, where the needed capacity is doubled when using object lock. Is the capacity requirement for backup storage appliances also doubled?Thanks in advance!

Cycles and Days Retention with Compliance Lock for Decommissioned Clients

After the recent recommendation notice, we’re looking to turn on Compliance Lock for our air-gapped Aux Copy, which uses Metallic Recovery Reserve as the cloud storage.The copy currently has a retention set to 28 days and 2 cycles.Our VM backups are set to back up via datastore, with Commvault automatically assigned each VM as it’s own “subclient”.  I’m seeing situations where a VM is deleted from VMware and the backup is being kept in the aux copy because it’s trying to retain 2 cycles, even though the server no longer exists.  We obviously would not want this to happen when Compliance Lock was turned on as there would be backups for decommissioned servers hanging around forever.  I’m guessing something similar would happen for other server that do have their own clients, were you to try and remove them.Does anybody know the best way to deal with retention in this scenario?Thanks

Data Verification on DDB

Hello,I am running Data Verification on a DDB. The Total Application Size of the DDB is 930TB. Does the Data Verification job need to process then entire 930TB? I’m not getting accurate estimated completion time as the job is showing as 99% complete with 600TB processed. It keeps adding more jobs for processing. Just want to make sure that I am on the right track.Thanks in advance.Fergus

Wanting to make sure this is Accurate on Quarterly retentions and Data aging

Question: I asked Gemini ai the following question below and want to make sure that this is correct way of understanding the retention of a Quarterly retention and data aging. Inside of Commvault when you have storage policies with quarterly retentions, how does the data that is backed up under that policy affect the license? Since it happens once a quarter does Commvault hold on to the data being backed up under the storage policy that counts towards the license? In Commvault, when you have storage policies with quarterly retentions, the data backed up under that policy will count towards your license usage for the entire duration of the retention period. This means that even though the backups occur only once a quarter, Commvault will continue to track and include the backed-up data in your license usage calculations until it is aged out according to the quarterly retention policy.Here's how it works:Initial Backup: When the initial backup occurs (once a quarter), the size of the bac

Description: Error occurred while processing chunk - error Code: [13:138]

Hi all!could you advice me how to troubleshoot following types of error: Error Code: [13:138] Description: Error occurred while processing chunk [xxx] in media [xxx], at the time of error in library [disklib01] and mount path [[xxx] /srv/commvault/disklib01/xxx], for storage policy [XXX] copy [Xxx] MediaAgent [svma1]: Backup Job [xxx]. Unable to setup the copy pipeline. Please check connectivity between Source MA [svma1] and Destination MA [svma1].  At a glance, it seems that it is not possible for CV to process chunk from the (index?)/disk library...However, the issue is connected with storage policy copy, that moves data from the disk library to the tape library (secondary copy). The main problem for us is that it is not possible to copy data to the tapes. Therefore, it may say Unable to setup the copy pipeline. The media agent is one server/device, that communicates with both disk and tape library. Lastly, the files in the related directories dont seem to be corrupted...Any suggesti

Clarification on Data Size Changes After Migrating to Azure Using Azure Data Box

Could someone provide insights into whether there might be any changes to the data size during this process? If so, what kind of differences should I take into account? The Azure Data Box is attached as copy to storage policies with deduplication active.Migration is from Azure DATA Box -> Azure Storage Account Thank you in advance for your assistance!

Questions about configuring immutable copy on azure and worm protection in commvault

Hi All, Our environment is a mid size enterprise setup, we have around 250 servers hosted on On-Prem and Azure. We have configured sync copy to azure with retentions of 10 years for the On-Prem servers and for servers on Azure we have just 1 copy of backup. We would like to have immutable copy on azure and worm protection in commvault. It would be really grateful if anyone can list down the steps and precautions to be taken along with price calculator. We would like to have a weekly full backup with 14 days retention and 2 cycles on this copy.We would also like to know if deduplication is supported? and what preferred storage type (Hot/Cold) on Azure is preferred.Can we use existing media agent which is being used for Sync copy to perform the copy on this selective copy?Does this solution offer a complete end to end protection from cyber attack/ransomware?

Can we run existing MAs without DDB & IndexCache after migrating them to new MA

Hello,We are having two physical media agents with shared disk library (CIFS) and tape library connected to them. We want to virtualize these media agents, however, after virtualizing we want to run the existing physical MAs for some time due to backup retention on the tape library.We want to setup new virtual MA, migrate the DDB & IndexCache to new virtual. Now the existing physical media is left with the tape library and no DDB/Index. Is it possible to perform restores from the tape library using these physical MAs?Idea is to run the new backups using virtual MAs and turn the physical MAs off when retention on the tape library expires. Thanks.

Exchange backups. File level backup on the servers and backups of the DAGS.

Hello, hopefully i have this request in the proper place and it has not been asked before.So I have 2 exchange environments because where is the fun in just having one. I currently have a 2013 exchange env. running 2013. Dag1also an exchange 2019 system. Dag2  My ask is.. We are only interested in backing up the databases within the dags. Which is happening and no issues, but today I was looking at capacity usage and I notice that all the DAGS are part of a multi server setup, and these servers are also doing a file level backup, to me it seems that this is a duplication of backups and I only need the DAG DB’s. can someone confirm this is true and I only need to be backing up the DAG data and not the actual servers that are doing a file level backup as well. btw, I am using the passive copies in the DAGS. thanksChris
