Storage and Deduplication

  When following the document on how to stop/start a Hyperscale X appliance node https://documentation.commvault.com/2022e/expert/133467_stopping_and_starting_hyperscale_x_appliance_node.html I get to the step unmount the CDS vdisk, and after getting the proper vdisk name and running the cmd# umount /ws/hedvig/<vdiskname>i get the message ‘device is busy’.What’s the proper way to remediate this and continue?ThanksG 

 We do see aux copy completed with error because of skipped jobs But we dont see the job id gui  not even in the logs. is there any way to see the job when it say job is skipped ?    

We have a storage policy with aux copies that was sending disk backups to a tape library. The library in question that contained all these tapes has been decommissioned. A new library was stood up and all tapes were put into this new tape library. However the aux copy that represents this data belonged to a different media server and physical library. We are trying to figure out how to take the data sent to the AUX copy in the old storage policy and move it to a new Cloudian array that has been configured as a Cloud library.

Do aux copies start after the backup copy time retention time was reached. Or do Aux copies start at the same start as the backup copy but just to a different location? I am aware Selective only does Full  and Synchronize does Incremental and Full

How can I confirm how many blocks a DDB data verification job processed after it is finished?We have a scheduled policy to check data consistency with the following options. It seems to me that the job is processing all single blocks.    

Hello. I’m trying to configure an Oracle Cloud Infrastructure Object Storage but it’s showing this error:  I already put all the information required to configure, such as: Service Host, Tenancy OCID, User OCID, Key’s Fingerprint, PEM Key Filename and Bucket.Also created a config file in .oci folder.What do I have to do to solve this problem?

Greetings!I’ve been involved in backups for quite a while, but have mercifully been using drives ~ not tapes.  I’m now having to consider tapes.  We have multiple SLAs, including:A monthly full backup to tape, retention to 62 days, lasts 1 month only A monthly full backup to tape, retention of 365 days - so 12 tape backups  A quarterly full backup to tape, retention of 365 days - so 4 tape backupsThe last full backup of the month goes to tape.  So, I forsee a single tape (or a group of tapes with a mess of… ) consisting of 1 month + 12 month retention times.  Some of these tapes will have jobs that last a year as well as jobs that expired months earlier.  What is everyone’s experience with such a thing?  We have over 750 servers involved here.  CV has but one tape drive currently and an operations group to rotate tapes.   Thank you in advance for any experience you can lend me…  Mike

Good afternoon,I wanted to check with the community before generating a case with support, regarding the number of outstanding prunable blocks. On a library, which has started to increase 1TB per day, we have applied a 'run space reclamation' and have recovered 30TB of 65TB it had in size. Although this library has only 6TB in use. It is strange. We are seeing a large number of outstanding prunable blocks but performing the 'run space reclamation' does not remove them.     

I am in the process of moving all our data from tape to a disk library and need to estimate how long this will take. Has anyone come up with a reasonably accurate way of predicting how long Aux copying data for a given copy would take.I have 6 x Tape Drives in a library. This has been used a a target for multiple Auxcopy operations for multiple Storage Policies. Due to tape contention a multiplexed multi stream Auxcopy for a Storage Policy copy could be written to 1 to 4 drives depending on drive availability. I am also interested to know how this works. When the operation began it copied the oldest data first , but as time went on the completed and partially copied data began to appear throughout the timeline. Is there away to make the most recent data copy first? Does an Auxcopy operation begin copying all jobs on a given mounted piece of media, or does it only copy some jobs and will have to mount that tape later. 

Hello,I created Oracle database full backup subclient every day at 2:00 AM and Oracle archive log full backup subclient every hour. Both data and archive log use same storage policy At storage policy level I created auxiliary copy with selective copy all fulls. But when I checked the jobs inside this auxiliary copy I can find oracle data full backups only and it is not contain the archive log backup jobs. The storage policy primary contain all data and archive logs jobs

Hello Every one,Our current storage is almost out of space, so we want to move all of the backup data to a new Storage.we are thinking of the following:- Create new Disk library contains mount paths of the new storage.- Move the mount path from old mount paths to the new mount paths.- Change the storage policy data path to the new mount path.The reason behind we thought of using moving mount path method, because using Aux copy method would require to stop current backup jobs while moving the mount path doesn’t require that.what is your advice about this approach

Hi All, we had an internal discussion for new customers what Library is the best way. Often we are running Windows Cluster withs csv volumes or windows filecluster or single servers with san attached storage.  In the past there are a lot of problems with the ransomware on CSV an Filecluster.  Do you have some more information wich way should be good or better to prevent redirected I/O in cluster and also errors during maintanance ?  Also is there any possibility to check if the ransomware protection is working on a CSV / Windows file cluster ? Sure the option is set but did we had an option to test if its working ? 

Commvault 11.18 (soon to be 11.20).    - We are on the cusp of eliminating our secondary backups to tape.   The benefit of a secondary copy on tape was the build-in air-gapping (and ability to move it offsite for safe-keeping).    We plan to move to creating our secondary copies on disk in a different city.   Commvault’s built-in Ransomware protection is  no-brainer, but WHAT ABOUT WORM?    What are the implications of the WORM storage on space consumption?   Is there any scenario in which a WORM-enabled deduplicated secondary copy that is a true copy of the deduplicated primary copy (and with the same retention) would be any LARGER than the primary copy?   Presumably, if a 1000 jobs share one block on the secondary storage, that block will not be removed until the last of those 1000 jobs ages out.Any info is appreciated.   Thanks!

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?
