Storage and Deduplication

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!

Hey guys,I’m currently using S3 IA for my cloud libraries (dedupe used) and  looking to reduce costs. The combined storage tiers look promising, in particularly Intelligent Tearing/Glacier. Has anyone got any experience in using this, and can offer some insight into its suitability? Cheers,Steve

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 

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

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

I cannot associate a Global Deduplication Storage Policy to my Subclient,  it doesn't appear in the Storage Policy pull down list.   CommServe Version: 11.28.44.  

Can anyone advise on how to integrate Infinidat with Commvault Intellisnap. Can we Use Commvault aux copies to copy the app-consistent primary snapshots to another storage array Or Commvault storage.Will these remote copy snapshots will be revert capable ?

Hi ,Please help me whare is the problem , & how can I solve?Problem:Error Code: [62:2855] Description: Error occurred in Disk Media, Path [Test_cat\UE3QA4_10.14.2022_15.56\CV_MAGNETIC\V_1] [-1451 OSCLT_ERR_MAXIMUM_DEVICE_LOCKS].

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

Hello Community,I’m currently in the process of migrating archive backups to Azure using Azure Data Box. I have a specific question regarding the overall size of data after migration. 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!

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?

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.

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 

We are running out of space and need to redesign.  I haven’t used Commvault in some time and forgot how.  

Hello Gentlemen, I would like help with the following error.A new Bucket was created in our Nutanix, with the WORM immutability function. And in commvault, when trying to create a new cloud storage, it presents the following error in the image below:  Note: I performed the test using the Cloud Test Tool software and the error returned talks "You must provide a Content-MD5 header with object blocking fields" .......Image below: Test Upload/Donwaload : Test Access Functionality Check: I am sending the Logs as an Attachment:CVD (taken from commserve)EvMgrs (taken from Mediaagent)CloudActive (taken from Mediaagent)

Hello Community,I am a tenant admin in Commvault so I don't have access to Commcell or Java console. But I can add NAS, servers, virtualization. I currently have a problem with NAS backups from Isilon and each incremental job takes 7 or 8 hours. The data size is 1TB and there are more than 2 million files.I first added a NAS, i.e. Isilon (with array), using add server and then a CIFS subclient as backup source. Since we already started with version 11.28, I assume that the changelist for Isilon is enabled. But I don't understand why an incremental job takes so long every day. Strangely, I see that after a synthetic backup, the incremental job only takes about 30 minutes. But the next day it will take 8 hours again.I would like to ask if anyone has had a similar experience. Many thanks in advance.Thanks.

Hi,I have tried to restore oracle database to disk but I did not find the option restore to Disk.

Hello,If a VM is being backed-up ( VSA backup ) from 2 different backup-sets using the same storage pool, is there any impact on the license consumed by this VM ? will there be a double ‘charge’ for it - per Front-End ( capacity license ) ?  Thanks

I am wanting to increase my level of understanding of the IntelliSnap Big Data backup and recovery process. I have searched the Community, Partner University, and knowledgebases, and documentation without success. Can anyone help with the followingProvide list of links or explanation that explains how this process works for backup and recovery and the differences between VM, San based Snaps, and COW(Linux Copy On Write). COW (Linux Copy on Write) Snapshots vs hardware snapshots, pros and cons Are there scalability limitations with COW snaps. A break down on what some of the options actually do when configuring the Big Data VMware snaps. The documentation either ignores or glosses over this. When using SAN Snapshots from a VM using Big Data (say mongo Idata agent), will I need to present the LUN as an RDM using NPIV. Is there a detailed method for doing this?

Hello, I’m during the backups migration from tapes to disk library. I have encountered the problem with jobs that are somehow disabled. The retention of job is still valid. Auxiliary Copy is skipping this job.This is the error that I’m getting when I’m trying to pick the jobs for copy  

Hi,Is there a way to identify files by name and location who where during the file scan marked as new?We know they are not new as they the data backupped is low.The reason is probably a right or attribute changed as we also see no modification dates changed.Data is located on a network share on a Isilon using a Windows File Agent

Hello, We’re currently establishing a yearly reporting for backup size of our systems.Can someone explain the difference between "Protected Application Size" and "Total Size On Media" in Commvault Reports? Thank you and best Regards

Hi,in V11.32, is there an option to change the data paths for a primary snap copy ?In former versions I could simply change the data path in the storage policy copy, but no it is bound to a storage pool, I intend to replace.The dedupe engines associated are already empty and I created new Storage Pools for the active backups copies and seondary copies.I’m not able to complete delete the Storage Pool, since the meta data of the snapshot jobs are still stored there.adding the new disklibrary to the existing pool might enable me to delete the currently used disk lib and paths, but the original StoragePool has to be maintained, although not really used to store backup data.rgdsKlaus

Hello All,We are using Linux Media Agents, on of the sudden media agent went offline with some communication issue with the ports 8400 & 8403 (we are using for communication) and there is no changes from server end.After restarting the CV services, it was back again, but we need to know that what is the reason it is going offline? which log to refer the check the actual issue, I have checked cvd.log, cvfwd.log but can’t find anything.Did anyone know, how can we exactly point to the issue with a log or event?
