Storage and Deduplication

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 slower disks”. Option B: But I also see documentation

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 enabledI opened a ticket in November 2022 and it was

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 

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 migration.Thank you,

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.

Hi, we are testing the file archiving on an isilon and the archiving itself works fine but it does not create any stubs.Error code: [72:106]Description: Warning: Job completed partially successful: Stubbing did not happenWe tested the same on a Netapp share where archiving and stubbing works fine.Does anyone have had any similar issues?Thanks

Hello,  We have the following Secondary Copy to LTO9 Tape Retention configured across all our storage policies. I want to see what others are doing for extended tape copies to optimize utilization, based on raw tape media capacity, we are using more media than we expected due to the mixed retention not fully allowing the typical son, father, grandfather graduation.  Also, does Commvault have a Media Calculator Estimator similar to Veeam’s?https://www.veeam.com/calculators/simple/vbr/tape TIA !

Hello,I'm trying to find a way to display the configuration of a copy that is part of a Storage Policy.Did anyone find a way to do this yet?Thanks,Br,Fred

Hey,I have some questions during preparation to migrate to the new MA.Before all this change I Matainance MA or Disable it. Which will be better ?I wanna replace OLD MA to new MA. So I use robocopy with /mirror and /copyall to copy DDB and Index( on the same place and disk letter).Then I turn off OLD MA and on NEW MA change IP and name (the same that have OLD),The next step is to install Commvault MA on NEW, and at the end of the installation, agree that there is a Client with the same name and replace it.Do you think it should work?And if something is wrong I have old Ma and can go back to him,

Ok, gonna post out here because I’m not sure where to go. I’ve logged a ticket, but I don’t think customer support is going to help me find out why all of our space is getting sucked up.First, thanks for reading.We are completely out of space and I have no idea where to start troubleshooting why. We went to the Metallic over a year ago for auxiliary copies (primaries are stored on location) and quickly used up our 45TB of space. 2 months ago, we purchased another 10TB and that is now gone as well.I just cant seem to find a process for troubleshooting. Could it be we are not reclaiming space? Are the backups not set correctly and doing a full every time? What jobs are taking the most space. I run some reports, but they are often just a wall of text that I can’t make heads nor tails out of.Anyway, I’m not helpless. I can follow some steps, but I don even know where to begin. I’ve only been around CV for a couple of years. But have a little experience with Veeam and Rubik. I’m used to 6 i

Hello All,we have Mongo Sharded Configuration backup on COmmvault. We backup it daily full. As you know COmmvault take snapshot before backup and , It deletes snapshots after backup copy. When I check the client on Commvault there is not any snphot presented. But There are many snapshot taken by COmmvault on host. İs it fine if we delete them manuelly or how can we delete them? Commvault should delete them automaticly right? Snapshots on host: [gbmnsp08]~#lvsLV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convertcvnv_1213025853 datavg swi-I-s--- 50.00g lv_data01 100.00cvnv_1615395985 datavg swi-I-s--- 50.00g lv_data01 100.00cvnv_2032137259 datavg swi-I-s--- 50.00g lv_data01 100.00cvnv_2251453908 datavg swi-I-s--- 50.00g lv_data01 100.00cvnv_2532432752 datavg swi-I-s--- 50.00g lv_data01 100.00cvnv_3191856748 datavg swi-I-s--- 50.00g lv_data01 100.00 

Hi CV Experts,  We are on 11.32.59.As per default schedule DDBVerf configured in our environment. It is selected as Quick verification.But in 11.32 documentation, it is mentioned default schedule to run with “verification of existing jobs on disk”. https://documentation.commvault.com/2023e/expert/verification_of_deduplicated_data.html Kindly note,we have 1PB of data, so running ‘verification of existing jobs on disk’ shows estimated time to complete as more than one month.Can we run default schedule with Quick verification.Does it identify the corruption or missing in chunks on storage ? https://documentation.commvault.com/2023e/expert/data_verification_of_deduplicated_data.html

Hello everyone,We still have some questions regarding IntelliSnap. I’d like to confirm if auxiliary copies made with IntelliSnap always use SAN and what requirements are needed to enable this functionality.We appreciate your assistance. 🥺🙏🏽Thanks in advance!

Hello everyone,I have a question about changing the Media Agent where I have configured DiskLib using to this the disk from my array.Now I want to refresh the MA to a new one. Could I for example move DDB, Index to the new MA and then reassign the disk from the old MA to the new MA and it should work fine or is there another way to do it more securely

I am experiencing significant delays with my backups despite having a high speed internet connection and no antivirus interference. I am unsure what might be causing this issue and would appreciate your assistance in identifying the cause.Could you please guide me on the best steps to diagnose the slow backup performance? 

With the Big Data Apps Indexes that write to tape, what happens if the storage Policy is changed to write to disk ?  

Hello Experts, We are in the process of replacing the Storage of primary backups and would like to take expert opinion before proceeding further. Our storage policy have StoreOnce as a primary copy (retention 30 days) and Tape library (retention 10 years) for the secondary copy. Going forward we want to replace the StoreOnce with Hyperscale-X for primary copy. The data on StoreOnce is copied to tape and we want to leave the StoreOnce for next 30 days to allow the data to expire. Now the questions are If we modify the storage policy and replace the StoreOnce with HSX, will we be able to restore the data on StoreOnce in next 30 days if required? If we create a new storage policy, how can we move the catalog of Tape from old policy to new policy? What is the best approach for this ?Appreciate your suggestions on this
