Storage and Deduplication

I have two sites, Primary and Secondary. Withe Auxcopy to the secondary site which is stores the only long term retention copies. We have firewalls in place so only the clients can only see the servers in the site they are in.This causes a problem when I am trying to restore long term retention data from the Secondary site to the primary site. We have a work around of Auxcopying data from Secondary to Primary site but would like a more elegant solution. I think there is a method where I can use a media agent in my Primary site to proxy my requests to the Secondary site to do these recoveries but cannot work out how. Any solutions appreciated.

Hello dear Commvault users and Commvault specialists, Our libraries are growing unexpectedly. Initial analysis revealed no visible errors. Our two media agents show readiness check OK. The Disk Library Growth Trend report shows data growth, but says not what exactly is the cause and doesn’t show where (which sub client) is the most growing object.That is why my question is, what options are there in Commvault to check the data growth to identify the sub clients, which are growing at most. Our Commvault version is 11.32.23. I would be grateful for any advice.

Hi Community,I had recently moved a mountpoint to and existing drive. The move mountpoint job had completed successfully, but the data from the old mountpoint has not been purged. The size is approx. 12TB.What can I do to purge the old data, as there is another requirement for the provided LUN.  

HiI have full backup daily.Basic retention is set to 7 day 1 cycle. I need to extend retention only for first Saturday of each month to 90 day.How to specific the first Saturday? 

Hi all,any advantages, other than security with removing attack surface, when using iSCSI attached volumes from a NAS directly to the Windows MediaAgent rather then writing via SMB to the NAS share?In regards of performance, ransomware protection etc?Your thoughts are highly appreciated, thanks in advanceregardsMichael

HelloMy organisation currently has a process of deactivating exiting staff members by removing 365 licenses.I therefore have two dynamic groups one active (which captures licensed users) and another disabled.  These two dynamic groups form the content for OneDrive for Business backups in Commvault. Office 365 app: OneDrive_activeusers                                    Content: backup_ActiveUsersOffice 365 app: OneDrive_disabledusers                                Content: backup_disabledusers When a user moves from one group to another Commvault seems to do a new full backup.  If this is the case, are we doubling up on the backups unnecessarily?Thank you.

Hello Team,I want clarification of DDB disk for an each disk library. We have three different storage hardware devices for different disk libraries.First disk library will use primary backup data, another disk library for monthly (selective monthly copy) and third disk library for Yearly backup (selective yearly copy) .These all three disk libraries configured in one media agent server.Just want to know each disk library will configure individual DDB disk or one disk will use these three disk libraries.Please advise.Thanks in advance.    

Can you please explain me why there is a space - but the same time it is occupied on disk?  

I had 2 disks go bad in my local iSCSI SAN late last week. I have multiple mount paths attached to it from Commvault. The array has since been repaired, and the RAID rebuilt successfully, but I continue to get these errors, and my concern is there is some disk corruption on the drive(s). The mount paths are formatted in Windows as ReFS. I tried running scandisk, but it’s not available on ReFS, but I could use the Refsutil to scan and fix the drive if necessary.I’m seeing the errors on Aux Copy jobs, which is interesting, cause all my Aux Copies are sending data to Azure, not the local SAN. Not sure if that matters or not.Any thoughts on where to go from here? 

Hi’After archiving some files in UNIX server  we are not able to restore them we can’t found this files. Regards. 

I’ve been discussing a topic with a Commvault user of an issue they are having. They do not use Commvault deduplication for their backups as they are writing to an array with deduplication. They are now looking to create a Secondary Copy of their data to replicate to Scality Ring. However, my concern is they are going to run into the same problem they did when they tested Air Gap Protect - the secondary copy inherits the primary copy’s compression settings (not enabled), so the deduplication performance is not where we would anticipate it to be.If that’s the case, is there any other feature out there that would allow them to write both a non-deduplicated copy (primary) and a deduplicated copy (secondary) with different compression settings? Documentation makes it look like you can change the settings for a Storage Policy Copy, but I believe it is only referencing the Primary Storage Policy Copy as the top level explicitly states the compression settings for Aux Copies adheres

Hello We have Commvault Recovery environment . All our Tapes are encrypted using IBM SKLM . Now we are planning to migrate the Tape data to EMC s3 storage to eliminate tape.What is the steps to need to create a aux copy to migrate the tape data to s3 storage. How to eliminate the encryption which was enabled on the Tape while migrating through aux copy. Thanks,Sandy

IHAC who wants to change from 3DES encryption to AES-256. I know we don’t re-encrypted data that already exists in the library, but the question is do we see a noticeable difference in storage consumption between ciphers? We list performance ratings here, but do any of them have a higher or lower storage consumption penalty?https://documentation.commvault.com/2023e/expert/supported_algorithms_for_software_encryption.html

Hi community,we are migrating from another solution to Commvault’s backup solution.Currently we are billing our customers per client and per used backup disk space. It would be great if we could handle the billing the same way as before.We are now looking for the best way the get the used disk space per client. Ideally directly with a SQL query. In another thread someone recommended the QS_BackendStorage stored procedure. While this looks like a good solution, we are not sure how to interpret the values. In our understanding the column ‘Backend Size (GB)’ contains the actual used disk space on the media agents per client. So adding up all those values should be equal to the used disk space on the volume.In our testing system currently 14.3TB of the disk space is used (by just checking the disk usage on the media agent - we currently only have one), while the sum of all values in the column ‘Backend Size (GB)’ of the sto

I have two sets of media agents, each handling completely seperate sets of backup data.Each set of data has the same storage requirements.I want to use a single S3 bucket but have two libraries/storage pools, so the DDBs stay with each seperate media agent set.So, can the same S3 bucket be referenced by multiple Commvault libraries?As my bucket is object locked I’d like to find out more before I make any connections to it.Thanks. 

Hi, We have an issue with the aging of our O365 backups. We have set the retention on the primary at 14 days/0 cycles but we can see data from 2022 residing on it.There are not Jobs waiting to be copied on the secondary.The Forecast report shows for reason for not aging “DataAging is disabled for special clients”.Data aging is activated at every level I have looked (Client properties, Primary policy copy properties).Worm storage lock unchecked on the GDDB as well as Compliance Lock.Compliance lock is not checked on primary copy.I’d like to know how I can handle the retention on my primary storage.Thx for your help.

We’re considering changing our storage retention policy from 1 year to something less than that and we’d like to know how much storage we’d reclaim by making this change *before* making this change (to see if its even worth it). Is there a report that could tell us this? Or how could we best gauge the effects on our back-end storage of changing our storage retention policy from one year to, say, six months?

Hi All, One of the customer configured the NAS Backup with NetApp SVM and enabled CIFS and NFS protocol under the same NAS client. https://documentation.commvault.com/2023e/essential/add_nas_file_server.html He enabled the snap backup at Instance level on each protocol (CIFS/NFS). But whenever he creates user-defined sub-client under the specified protocol, the snap-backup was not enabled by default and need to enable by manually. Would like to understand that whether it is a behavior by design or anything I need to do extra to automate it?

Does anyone know how to retire an Index/Analysis Server that contains roles?  I can get all of the roles to remove except the last one.  I also just attempt to right-click on the Index Server entity and choose Delete, but it says that it is associated to DC Plans [ODA_DCPLAN_8534] and to remove the connection and try again.  We only have 2 plans - Threat Analysis and FSO.  There is no association or relationship I can find in the Command Center to either plan let alone any other backup plans.  All I want to do is delete the Index Server I created - there isn’t any data on it.  It had another node on it at one time, but I also removed that from the configuration hoping to tear it down one piece at a time.  Please help!  Very frustrating.  We are running Windows Server 2022 on the CS and FSO/Threat Analysis on the 2 Index Servers.  These servers are VMs.  

Hi Community,We have Data Domains as our primary storage for Commvault and tape for long term retention. We are looking to replace the tape libraries within the next year with DD Cloud Tier. With DDBoost now fully supported as access and client libraries does anyone know if and when DD Cloud Tier may be integrated and supported.

What’s the command to get the gluster version ?For the OS we run uname -r which gives us the following out put.3.10.0-1160.108.1.el7.x86_64Looking for the same detailed output in a gluster version command. We should be running version “6.0-63.el7rhgs.x86_64” and would like to verify that we are. Thankshttps://documentation.commvault.com/2023e/expert/hyperscale_1_5_platform_version_1_2403.html

Hi Everyone, We Currently have Commvault commserv (All VMware Environment) targeted to HyperScale appliances. However, HyperScale 1300 is EOL/EOS. We have a spare HP MSA 2050 SAN storage available and require your advise before we configure it as a library.As HP MSA being an entry level storage, is it recommended to be used as target library even though disk speed are 7k for  HyperScale and HP MSA? Would there be performance issues as storage needs to mounted to additional server server to be used over 10 gig network as VMware does not have SFPs? Would configuring backups on HP-MSA give us same dedeuplcation ratio as that of HyperScale appliances ?

The process of setting retention to half what is actually required, combined with the periodic sealing of the DDB seems clunky, and results in significantly higher storage usage - can we expect any improvements to that process?Where an existing block is referenced during an operation, could it be more efficient to just extend the Object Lock retention for the associated S3 Object?

I have created a disk library in our dev environment which is using it’s own separate volume. it will be used for ddb backups. If I want to increase the capacity do I have to add a new volume or can I just resize the underlying volume in linux ?  

DearI need to carry out a survey of the growth of data volume in my backup environment, a comparison of growth over the last few years.Would anyone have a step-by-step guide on how to generate this report in Commvault?This information will be necessary to justify the calculation of data growth projections for the coming years.Thanks in advance for your help.
