Storage and Deduplication

Looking to start a replication group from a VM and default backupset to a mount path on a dell powerscale. Going forward this volume will be san hosted instead of mounted via a server. Upon looking at the config- i dont see an option. Im away replication groups are agent to agent. I thought about makign a library with the location- but even that doenst allow. 

Since the other thread was stated as solved I’ll start a new one. From What I understand the Network Throttling on the media agent only effects backup jobs, not Aux copies jobs bandwidth.There is an option to limit the Aux copy bandwidth usage by setting the Advanced setting "Throttle Network Bandwidth(MB/HR)" on the stg policy copy.Unfortunately that effects the usage all day as there is no possibility to set it per time interval.I have two Aux Copy jobs running for two different Storage Policy copies with the setting for bandwidth limitation set to 5000 MB/HR which is roughly 11 Mbit/s.So running two of those shouldn't use more then 22 Mbit/s.Looking at the Current Through put they are 3,92 GB/hr and 2,97 GB/hr in Comccell console. Those combined gives 6,89 GB/hr roughly 15 Mbit/s. I understand that it's not 100% accurate as the data is deduplicated.But looking at our monitoring I see two streams going to Azure one using 30 Mb/s

Commcell v11Backed up server folder needs to be restored from multiple backups which are on multiple tapes over a one year timespan. (38 Full BU)We need all backup from the full year. Looking for a way to complete this short of doing individual recoveries. Suggestions?Thank you.

Hi team, i would like to desactivate Commserve DR to tape (Version 11.28.10)Try to delete policie but have an error “ Manual deletion of jobs from a worm storage policy is not allowed”thanks for help.Regards

Afternoon allI have a few questions - hopefully nothing too complicated!I have recently configured a tape library in our Commvault environment which appears to be working OK - I just had a few questions around configuring the tape library to suite our needs.The plan is to backup to tapes so they can be take offsite daily and used in a DR scenario. We would like to keep 3 weeks worth of data on the tapes and would like to have a tape for each day.I’ve configured the auxiliary copy job and the related schedules to backup at a suitable time which I think so far is fine however where I appear to be struggling is with configuring Commvault to backup to a new tape each day.We will have 21 tapes and as an example tape 001 will be week 1 Monday, tape 002 will be week 1 Tuesday etc - tape 007, 008 and 009 will be Friday, Saturday and Sunday respectively.There will be x2 SP’s that will be backing up to tape - my question is, is it possible to configur

Hi, I’m asking if i can add HPE Tape library to the Hyperscale appliance by adding HBA adapter then connect the Tape library direct to to it

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 W

Hi Community ,Can we take a backup of S3 bucket which is 80 TB in size using Commvault ?Consider 10-15% daily change of data. How does Commvault takes backup of S3 . IIs it streaming backup , reading objects 1 by 1 which i expect would be very slow or some sort of Intellisnap capability is available for S3 backup ?Regards, Mohit

Hi Guys, Our on-premises Commvault infrastructure is with 2x Media Agents, 1x Tape Library, and few proxies. The backups - Primary on disks and the Secondary on Tapes. We are planning to migrate the Secondary copies over to Azure Storage and here’s our plan,Placing Media Agent in Azure  Placing DDB in Azure (on Media Agent) Switching Auxiliary Job Migrating old data from tapes to AzurePlease provide some guidance and best practise on this.Thanks in advance.

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?

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. 

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.

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:

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?  

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

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

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. SFileNum [1] != [1] || CcId [2] != [2] || Offset [610712232] + [378000] != [611279232].- Customer to install MR23 on source MA.So we decided to upgrade to 11.26 as it is the latest and has all fixes as 11.25.32. But can we wait for 11.28 and upgrade to 11.28. Will it have same bug fixes as that of 11.26. 

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?     

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. 

Hi Guys, Hope you’re doing well !We have some DDB backup jobs that completes with errors.The job lasts 1 seconds only. In the events, it shows the below message:“job completed immediately as none of the stores are eligible for backup” Do you have any idea on what could be the reason?Thanks a lot for your usual help. Best Regards

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.

Hello. We're interested in creating a new MediaAgent (I'll call it MediaAgent03 or MA03 from now on) in Amazon Web Services, using commvault's "combined storage tier" functionality with S3 Glacier Deep Archive being the coldest (and cheapest) possible data option.This mediaagent would only be used for Data Restores in the event of a catastrophic event in our datacenter where MediaAgent01, our primary onsite MA, is stored. Otherwise, it will sit there quietly in the AWS cloud as our insurance policy.I was looking at Amazon's pricing page here - https://aws.amazon.com/s3/pricing/ under Requests & Data Retrievals Tab - and was wondering if commvault can please explain or provide documentation as to how to calculate 'retrieval request' operations. I of course understand 'data retrievals per GB' cost because I know in a DR situation I'd be restoring basically everything, 100% from MA03 - about 200TB of data at the moment.However, what I don't understand is how co

On Sealing the Deduplication Database page there is a note. Can I perform Synthetic Full Backups of associated subclients manually instead of traditional Full Backups? 

Can I move a partition from a SEALED DDB to the same partition path where the active DDB is located? I just sealed the database before move the partition.
