Azure Cold and Archive

Hello All, We are using Azure Cold data to store our off-shite copies. We have been using this from last several years. Lately, we decided to use Azure Combined storage and planned to move/copy data from Azure cold to Archive storage. After having a discussion with Commvault, we implemented what was suggested but this process seems to be really slow and case is now escalated to Dev. Being honest, we are seeing terrible delay from their side too. I am question is now, If instead of using aux copy to copy the jobs from cold blob to the combined tier library, what if we changed the tier of cold blob from cool to combined tier?  If we did that, would the data convert to archive, or would that only effect new data written to that storage?

Enable worm on Cloud storage library

Hi Guys,We have a Huawei Object Storage and would like to enable WORM on it.We found out that there is a Workflow to achieve that:https://documentation.commvault.com/11.26/expert/9251_configuring_worm_storage_mode_on_cloud_storage.htmlHowever, the link is a bit confusing: It says that the Workflow is compatible with cloud storage vendors that support the WORM and at the same moment it gives a list of vendors.My question is: Can I use the Workflow with my Huawei Cloud Storage (WORM Compatible)? Also, the link says : “If you have multiple storage policies/copies created using the cloud storage pool, make sure to set the same number of days as retention in all the copies.”Does it mean that the Cloud library will host only copies with the same Retention when WORM enabled? Thanks in advance for your usual help. Best Regards

Cloud Library - Capacity Metrics not showing

CS Ver FR 24I have on on prem S3  solution. I have presented this to Commvault as a Library, with multiple buckets as mount points. Within Commvault I have limited the size of these buckets  to 100TB (performance tuning for library, decided not to limit buckets on storage side). You can see, size on disk of data in the bucket   Commvault therefore has enough information to calculate  Capacity, Free Space, and Usable Free space when I view my library and mountpath stats, but I see nothing.    Any suggestions?

DELETE HPT CATALYS

Hi I need your help, in the initial implementation, the customer added a machine running debian 11.00 as MediaAgent, and it is not supported as it only allows to configure HPE-catalyst storage and not the libraries. Therefore the client uninstalled this debian OS from the mediaagent, and now I see that I can not remove the HPE-Catalyst.At the moment I added the mediaAgent with Ubuntu OS and it manages to see both the disk storage and the libraries.The error is about WORM media data.

Pruning on isolated MA

Hi Commvaulters, Had a question regarding data aging/pruning on isolated MAs.So, we have an isolated MAs (Air gapped = They are powered on only during Aux Copies, then, when the last aux copy finishes, the MAs are shutdown), the data is Deduped. All jobs concerning the MAs are rescheduled to be aligned with the Air Gap window (Aux Copy, DDB Backup, Data Aging...etc). My concern now, is that the Air Gap window may not be sufficient to process the data pruning on the storage, since the MAs are directly shutdown after the Aux Copies. Can the Air Gap window be an issue for the data aging/pruning process ? If someone gives us some guidance regarding this, that would be great. Regards.

Catalog jobs from a cloud storage object

Hi Guys,Is there a way to catalog jobs from a bucket within a cloud storage library, like below:The tool offers only a Tape or a Disk as a Media. How do we retrieve our DR backups from a Cloud storage in case we lose everything in order to perform a Disaster Recovery.I found the link below, however it doesn’t show how to retrieve the DR DB.https://documentation.commvault.com/11.24/expert/43588_retrieving_disaster_recovery_dr_backups_from_cloud_storage_using_cloud_test_tool.htmlI’ve also found the below note:Does this mean that if deduplication is enabled, there is no way to retrieve the DR DB?Thanks a lot. Best Regards

Is it possible to change Azure Cloud Archive library into Azure Cloud Combined Storage Archive/Cool Library

Hello Commvault Community!,I have a question in the name of one of our client.We have created a Cloud Library (Azure Archive) - and copied around 40TB of data into the Cloud.It tooks us over 2 months to transfer this amount of data, when it completes we then realize that there is a problem with Cloud Recall workflow - when we try to “Browse and Restore” from CopyPrecedense (Azure Archive) - It is trying to reach an Index from this archive cloud (it runs a job “Index Restore” and it can’t find index data because it is archive storage, so it runs a Archive Recall workflow to recall an index data to be able to list the backup data - this worlflow fails after few seconds and we can find an error in Browse and restore window: “The index cannot be accessed. Try again later. If the issue persists, contact support.”.We decided that restoring an index from archive cloud isn’t good idea, because even if it would work - it would take too much time (few hours just to list backup content (index res

Disable deduplication on CommServe client

Hi Guys, Is there any way to disable dedup only on one single client only ?In our case, we have a Storage Pool which has Dedup Enabled, the storage pool is used to store aux copies received from our main site. The main thing is that from all the aux copies that are sent to the storage pool, there is the one of the CommServe DR backup. As per our knowledge, in case of a DR scenario, we have to use “Media Explorer” utility on the MA in order to retrieve the CommServe DR backups from the MOUNT PATH, and from the documentation, the tool is not usable when the data is deduplicated, as per below :From this came the need to disable the dedup only on the CommServe client or from the CommServe DR storage policy, and if there is any way to disable it for the CommServe only, is it really sufficient ? Since the storage pool is using deduplication, or does the CommServe DR Storage Policy has to be assigned to a specific Storage Pool that does not use Dedup ? Any advices regarding this would be grea

Best practices to ensure maximum streams for Aux to MCSS

Hello Community We are doing a pilot by pushing around 50t of data over to MCSS. We have noticed that when the jobs are progressing, there are multiple streams of different sizes at the beginning of the job and as the job progresses the number of streams go down. Is there a way to ensure that the data that is being pushed to MCSS is distributed among multiple stream equally so that we get consistent performance out of the job till the end?

Restores from Azure Cloud Storage

Hello,Our client ask me how restores from Azure cloud storage works when data is located on cool tier and on archive tier on Azure.We have tested the archive tier first. We copied the data to the cloud archive storage, and performed an restore for a database. We selected only one (of many) database which should have size lower then 10GB, but the full job backup size is 8,5TB (Size of application) - Recall archive workflow is working for 3days and completed only 30% - is it recalling all 8,5TB of data from archive storage?And how it would work if we use a cool tier cloud storage - when data is phisically available (online). If we copy a job which have 8TB and we will perform an restore only for one database (~10GB) from this huge backup - will it download all 8TB of data or will only choose this chunks which actually contains the data of this small 10GB database?Thanks in advance for help :)Have a nice day !Regards,Mateusz

How to Reduce Random Read Load on NL-SAS Storage Arrays?

Hello,We are seeing a very large random read load on our Hitachi G350 backup storages with NL-SAS disks. These random reads are completely consuming our backup storage performance. We have two G350s on campus and a third at a remote site. Commvault runs copy jobs between these three G350s.DDB is on NVMe locally in the Media Agent, also the Index Cache Disk.We ran several analyses and Live Optics showed us that the daily change rate is 334.9%, which is mainly due to the Windows File System policy, for which we see 2485.1% daily change rate.Does anyone know how the random read load could be reduced since our disk backup is otherwise unusable. What steps could we take to optimize the Commvault configuration?Screenshot: Thanks for your help!

I am getting Data Path Not found errors?

Hello World, I’ve recently replaced my media server and noticed my auxiliary copy jobs is getting this error whenever i try running the backup:User specified a data path which is not part of the data paths in the storage policy copy. Advice: Please specify a job data path which is part of the Storage Policy copy. Can see that the new media server has access to the library, but not sure what else to check.

Error Code: [19:861] Could not connect to the DeDuplication Database process

Hi,We’ve been having this Error (Error Code: [19:861] Could not connect to the DeDuplication Database process for Store Id [xxx], Process:clBackupChild, JobManager or clBackup) on multiple clients recently (agents seem random : Linux FS, Windows FS, Oracle RAC… v. 11.24.34). Our network team did not change any FW rules.The only temporary solution we found for backups to complete is disabling Client Side Dedup on all clients having the error, but we would prefer not having our MAs do the dedup.If anyone had a similar problem, any suggestion and ideas would be appreciated!Regards

Please confirm that the 11.28 version contains all of the fixes found in 11.26.

Below is the analysis from commvault: - StoreOnce Aux copy failing due to "Unexpected copy parameters. SFileNum [1] != [1] || CcId [2] != [2] || Offset [0] + [71680] != [73728]."- FR25 MR23 contains the fix for the issue you are seeing.https://documentation.commvault.com/11.25/assets/service_pack/updates/11_25_23.htm3395 -- AuxCopy jobs from HPE StoreOnce catalyst libraries as source and destination may fail with Error "Unexpected copy parameters.

But can we wait for 11.28 and upgrade to 11.28. Will it have same bug fixes as that of 11.26.

Drive reported that media is physically bad

What happens to backup contents from media that an LTO drive reported that It is physically bad? Does the Commvault copy those not-aged jobs from source copy to other media (tape) again or It just prevent reuse the media and retire it after expiring jobs?

Data Pruning on Cloud Storage Pool with Hardware WORM Enabled

Hi All, We’ve created new aux copies to a newly created cloud storage, with Hardware WORM enabled on it.The aux copies use Dedup, the retention on the copies is set to 15 days, and on storage, the WORM lock is set to 30 days on the bucket level.We also run the “Enable WORM storage” workflow to seal the DDB after 15 days.How data aging is working in this case ? How data is pruned from the storage ? After the copy retention has aged, how the MA can prune the data from the storage when the WORM retention is still active on that particular object ? If it cannot be pruned after 15 days, and the MA has to wait for another 15 days (In order for the 30 days WORM storage to expire), can the data still be pruned after 30 days ?Any clarifications on how this process works would be great :)Thanks.

Unable to change value of "sparse support" checkbox in Disk Library

Hello,We just added more storage to a mediaagent, via a new mount path in an existing disk library. The new mount path is an SMB share from a Dell Isilon, and the admin of the isilon confirmed they had enabled sparse support for the share - but he turned it on, after I’d already added the mount path.As this user in the Commvault forums described, I should just be able to check/uncheck the checkbox for ‘sparse support’ right? It is not working for me though. What is the trick to changing the status of this checkbox? Are there other ways via the Web Command Center, or CLI, to do the same thing?I also don’t see any means in the ‘properties’ of this mount path to enable this.
