Storage and Deduplication

Hi Guys, i have Quatum scalar i3 tape library, which is connected to the MA via 8 GB FC link. The library has one LTO 8 drive and also the Active Vault licence. what i want ? every friday synthetic backup to tape - i have dedicated 20 LTO8 media in Online, Partition, after backup the media will be exported to the offline partiton in the library.  every day bigdata index and DR to the another for example 2-4 media, these media will be online in library and not exported after backup to offline partition, because DR and indexes use only about 20 Gb per day and LTO8 has 11 TB = wasting of tapes. How to configure it ? any advices ? 

Hi Experts , I have been  task to migrate data from 7 years retention Tapes to our new store once catalyst stores library.The original tape library is already no hardware support and broken and it is also in a different CommCell. after merging the CommCell clients. I am able to see the Tapes storage policy copy ( the primary copy is on a disk storage which is also not recoverable any more.) I am thinking to use aux copy but from  console it seem I can only copy the tape to another tape using the new tape library on loaner for migration purpose by HP. Is there a way to use the loaner tape library read the tapes and direct copy to the Store once catalyst stores?

which is better. Which commvault does the encryption or does the storage do it?

HiIs there a way to have commvault re-order the sequence of tapes in a library eg move the lowest sequence barcode to slot 1, the next to slot 2 etc

Hello,I have a DDB Reconstruct running of a secondary copy that writes on Storage S3, the DDB backup writes on both S3 and CentricStor, i want to restore the DDB from the CentricStor library but it always try to restore from the S3. How can i force the restore from 1 specific library?This DDB is partitioned and only 1 partition is offline. Thanks,João Amaral

We have incremental backup copy jobs failing due to lack of free space during index restore; I was reviewing the Index cache and noticed F:\IndexCache\CV_SnapMetadata\2\3568\1737471697 showing over 239GB of metadata.  From what I understand this folder will have all the indexing metadata from all the Intellisnap incremental jobs; this specific job have not had a full backup(I am investigating the reason) for some time.  If I were to take new full backup what will happen during the backup copy; would it still try and restore historical incremetal index data as historical incrmental backups have not copied across or because this is a new full it will only copy the most recent backup copy. What if I manually delete the old snapshot and just keep the most recent would that avoid incremental backup copies and just copy the full backup without restoring index and would it clean up this metadata     

we had exchange archive to the primary storage policy which was hyperscale x 1.5 , and an aux copy to windows with local disk  , the jobs in the primary  copy is cleared .hyperscale x primary → first aux copynow as part of the hardware refresh we introduced new windows server and copied from second copy first aux copy → second copy but we are seeing a diffrence in the media size , 0 tb diffrence  first copy second copy 

Can anyone advise on best configuration for using Isilon as back end storage for on prem Commvault. Would you use Linux or Windows Media Agents ?

Hello, I am trying to restore mailbox but i am getting error in Webconsole: Browse failed due to internal web server error. Please check DM2Web.log for more details.In the DM2WEB log on commserver i dont see any errors. When i am trying to restore from java console the option to browser and restore is grey out  Do i still need to install outlook app on the MA to browser? 

Hello Guys,I will be adding a new media agent to our existing comcell environment. After installing commvault software on the new media agent and sharing the mount paths of the disk library with the new media agent. Will the storage policies associated with this disk library be updated automatically to include the new media agents in the "data paths" tab? Or should I manually navigate to each storage policy and add the new media agent in the "data paths" tab?

Hello, i am trying find out why the backup of big data apps of MS365 not working anymore. But cant find any issue in the logs. Here is the log from last job. Thanks for the help.  

My Aux Copy jobs going to Metallic cloud storage have been stopped for the past three days. I’ve asked my network team if there are any issues and they are asking for the connection information. I can see my on-prem media agents easily enough but can’t seem to find any of the details for Metallic. How do I find network details on the Metallic cloud storage?

Can Commvault backup a volume from a C60 and restore it to a C50? C60 is in our Production environment and C50 is in our test environment.

Hi all,I need to archive files for 1 year, but I do not have the archive licenses.My current configuration is as follows:Storage Policy: 1 year, 0 cycles. Incremental backup every day (the first backup was a full backup). A share where files to be saved for 1 year are deposited. If the incremental backup completes successfully, a Unix script deletes files older than 15 days from the share.Problem:The jobs do not expire after 1 year. Thanks

Hello Community,We recently acquired a new infrastructure that includes Commvault version 11.32.69, an HPE ProLiant DL360 physical server running Windows Server 2022, and an HPE MSL2024 library with two LTO9 drives. This infrastructure was implemented to back up a small environment consisting of SQL databases, a VMware 6.0 environment with 20 virtual machines, and some SQL Server databases.Although the initial setup seemed promising, we have encountered two significant issues that are impacting our backup operations: Excessive Cleaning Cartridge Requests (Case 250110-656) 🧹: During backups, the LTO9 drives frequently requested cleaning cartridges. This issue persisted even after HPE replaced both drives three times and after adjusting the Drive Clean parameter in the library properties to a value of 515. Low Backup Performance (Case 250110-659) 🐢: In our performance tests, we were unable to exceed a backup speed of 250 GB/h for virtual machines and file system backups. This perform

We need to move the current CommServe environment to another server due to space issues on the current server.What are the best practices for conducting this migration? 

Hi,I am testing 11.36 version and realized Commcell Console is not installed anymore with new installations.I you need to use Commcell Console you have to request to technical support.Is there a way to configure Gridstor from Command Center? Regards, Matias

 Here is a screenshot of the current status of the ddb.   Backups are running over desired time windows with 98.27% of load being ddb lookups.   We are close to capacity currently with backup storage though this will be resolved soon.   How can we resolve the high DDB lookup % issue?DDB and job status screenshots below.   

Has anyone had any major issues after install 11.34.44?  Failed to mount disks, slow throughput, VSBKP disconnects constantly.

Hi Guys,I have disk library with 8 MPs inside and 1 of them selected /plan for decommission as i dont need it or must destroy hardware under it (mean plan for decommission as selected on MP level “disable MP for new data” + “prevent data block references for new backup” 1st mine question is why CV still, after so many years on market,  have no possibility to decomm MP. Mean here simple click on MP from GUI and then options “decomm it” which will move/spill from that MPs to other MPs in the same library all data (jobs) and  dedup data for jobs ?  And again as probably will be here such suggestion i dont want move MP to other place  as i want to get rid of it and have clean environment beside to remeber that MP called X is laying here but i real is not need :( ! But as i have not what i want i must take longer way to achieve what i want so wait till data decommiss ….here lucky if user have not INFINITIVE retention as then CV is as child “can not do anything”But let imagine that we have 1

Hi Team,I want to understand how exactly the space reclamation job works and why do we need it when we have Data Aging. What is the Data verification and how it works in the background. Thanks.

We have doubt about Disable WORM storage lock feature.Currently we are on 11.32.59 and storage is Netapp GRID and HPE Catalyst.We are planning to enable the Storage lock feature. If in case we have to disable the WORM storage lock once enabled, we have to follow the below steps.https://support.commvault.com/Article/Details/82504 In our environment we dont have SMTP configured.What is the workaround here? Please advise.  

Currently we have our MRR Backups set to have a monthly Full set to be stored for 2557 days, which is 7 years.  This used to be the way we stored tapes but I feel that we need to change our thinking, as our system has 7 years of data and we did a full when we switched over to MRR which was uploaded.  So for our Company Policy in theory every monthly full has 7 years worth of data.  So at most I would think saving a year on the cloud is fine.  It would keep us safe from most issues unless something sits for a year without being found or triggered.  Long way to get to my question.  If I change our extended retention from 7 years to 1 year will it need to run a new Full Backup and reupload everything again or will that first backup we seeded at the start will just be there and all the other backups will just age out after they hit 1 year?  I really hope that makes sense, it does in my head.  Thanks for any info.

Hello,We have Commvault server, simpana version 11.28.68.We have situation that we want to keep the old backup whose retention expires soon. Also we disabled the schedule policy for this specific subclient.Is it recommended that we disable Data Aging for this Storage policy?If we disable Data aging for this Storage policy, backup jobs should not be deleted regardless of  exceeded retention?Best regards,Elizabeta

Hello Community,Based on CM's documentation, you can accelerate backups by installing the Storage Accelerator software on clients. https://documentation.commvault.com/11.20/accelerating_backups_to_hpe_storeonce_catalyst_storage_library.htmlQuestion: Is this functionality supported when the StoreOnce appliance is connected with Commvault via Fiber Channel?Thank you
