Storage and Deduplication

Hello everyone, I would appreciate your help.I am trying to download several files from my OneDrive backups, I choose to download it in a different location and not in the original location.What happens is that an empty folder is downloaded.What could be the problem?

Hello,I am curious to know, if I manually erase a tape using Quick Erase, are there any tools that can recover the data? I know Media Explorer cannot.Context - I am contracting with a customer who has not erased tapes and there are years worth. Of the latest LTO8’s we have decided to recycle those that are expired. I am trying to help with a decision as to use Quick Erase or Full Erase in advance of recycling them.The documentation describing these options has the following under Full Erase:  “You want to delete sensitive data”.Does this mean that sensitive data, or any data, can be recovered by any means using Quick Erase?System in use is self hosted v11.32.59 across 15 sites each with a media agent and tape library.Thank you in advance for your help.RegardsGerry  

Hi, came across on a issue with a cloud library. I had the need to reconfigure the cloud library and remove it and add it again with the same name. the issue is that from the DR backup option it shows two: from command line I can also tell that there are two   from the Storage Menu, I can see only oneis it secure to delete the one that ends with _1724845300? is there any way to tell the creation timestamp of both ? version is 11.34.36 regards

CSDB restore from media explorer on HPE catalyst?We are using hpe catalyst library and DR storage policy is configured to write to HPE catalyst.If in case of disaster how do we recover most recent backup using media explorer.https://documentation.commvault.com/2023e/expert/retrieval_of_disaster_recovery_dr_backups_from_storage.htmlI dont see such option in BoL.Please advise. Even though command center shows the HPE storonce as cloud we cannot run cloudtesttest on this storage I believe,

Hi! We trying to create a Recovery Point to recover a specific e-mail but the job fails after a couple of seconds. We do see a “ Error Code [655362] returned - [Error decrypting password]. “ in the logs. Not sure what password is referenced here. It concerns a intellisnap snapshot which is available on the storage. Has anyone seen this error before?

Hello Community Members. We are using Commvault IntelliSnap with Infinidat storage. Everything works fine except the device cleanup on the Linux hosts. Most of the hosts are getting alerts for path failure and IO errors at the end of the IntelliSnap backup while the unmap and device cleanup is performed.   We did check the difference between the servers which are not alerting, and which are alerting.  The main difference we can see in the IntelliSnap log is about “ISHDM IntelliSnap Linux Host Device Manager”. But I can’t get any explanation about ISHDM on Commvault site or on RedHat. Can you guys help me to understand what does this value /settings does better than normal “classic OS utility interface” If the above setting is not related to IO error/ path error / device cleanup, please let me know if someone experienced these types of issues on Linux hosts while performing IntelliSnap backup.  Logs found on the server with no IO error / path error. 3724588 38d52c 09/04 19:45:21 1701177

Hello Community,Recently, we connected an FC HBA 3660 StoreOnce appliance to our Commvault v11.32 backup server. The catalyst store on the StoreOnce is configured for low bandwidth, meaning the backup server (media agent) performs deduplication and compression, sending only new data to the StoreOnce.We have created a storage pool that uses StoreOnce as the backup target, followed by a storage policy based on the StoreOnce storage pool.However, it appears that Commvault, by default, disables deduplication and compression on the storage policy.Could anyone advise on how we can enable the deduplication and compression? As StoreOnce is configured for low bandwidth, we want the backup server (media agent) to handle deduplication and compression, rather than StoreOnce.Thank you,

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

Backup Type: Virtualization VMwareProxy: VSA WindowsStorage: Dell Data Domain Client LibraryQuestion: Customer would like to use the client (VSA) direct mode (storage accelerator) backups for VMware virtual machine backups.

When I use WORM-enabled storage policy to backup a file. I can see from the Object store logs that the PUT requests include partNumber and uploadID. See the example below.PUT /2.6wormtest/Z5YO4V_09.06.2024_10.43/CV_MAGNETIC/V_342/CHUNK_1294/SFILE_CONTAINER_020?partNumber=1&uploadId=7ffffe6e38ff88e4 HTTP/1.1When using a NONWORM policy to backup the same file, the received PUT request does not include the partNumber or uploadID. See the example below.PUT /windowsnonworm/1DWYIV_09.11.2024_10.49/CV_MAGNETIC/V_8220/CHUNK_84999/SFILE_CONTAINER_001.FOLDER/0 HTTP/1.1" 200My question is, does Commvault not employ multipart upload during a backup with the standard (WORM disabled) policy?

I have a bunch of data in a very end of support tape library. I need to get it out of teh tape library and into somewhere else. If I configure an HPE Storeonce library and use that as an auxcopy target will the storeonce be able to deduplicate the data coming off tape? I’m unfamilair with Catalyst - and I vaguely recall that in an aux copy scenario chunks are moved from place to place without any actual processing that might be required for catalyst/dedupe processing.

Hello,I have a I have a small customer who has a secondary media agent that receives aux copy. its DDB size is over 2,5 TB.What is commvault recommendations about that?We plan to perform a hardware refresh of the Media agent maybe be I can reduce the DDB size during this operation ?Thanks !

Hi. for this KB https://documentation.commvault.com/11.16/configuring_space_check_for_software_installation_and_system_directories.html Do I have to configure this for each client? Doesn’t seem to work at the Commcell level. Maybe at the group level? 

Hi Guys,I know this type of error has already a solution, which is either to suspend and resume the job or to run a verification job data, but both have not worked. Does anybody else have any suggestions ?Error message : Error Code [12:138] Description : Error occurred while processing chunk [XXX] in media [XXX], at the time of error in library [XXX] and mount path [[XXX] E:\MAGLIB\SATA15], for storage policy [XXX] copy [XXX] MediaAgent [XXX]: Backup Job [XXX].

Hi All,I am checking my DDB’s in Commvault and for VM and DB backups i am getting 17% and 40-50% DDB savings respectively.Please let me know what can be the reason i am getting very less DDB saving and from were i should start troubleshooting.If possible provide troubleshooting steps. Regards,Rahul

We currently have a 3 node Powerstore cluster deployed and we are looking to leverage the internal Powerstore cluster data migration to move a volume and all of the volume snapshots between arrays in the Powerstore cluster.As these snapshots were taking by CV IntelliSnap and not committed to the Isilon were we keep backups yet can we still go ahead with the migration and well not break anything?I can’t find anything in the documentation that can support this question either way, but any feedback would be awesome!

Hi Team, From what I can see in the document, in the Commvault FR20 version, it is possible to discover NAS systems live and get a report. However, I think this feature is obsolete. Is there a feature that can discover NAS systems live and provide a report with the 11.32 version? https://documentation.commvault.com/11.20/nas_system_discovery_report.html

I have a customer who has excess Hadoop capacity that they would like to use for a long term storage target. I saw the below link on BOL that caught my attention as a possible solution, but I think this is just using commvault to orchestrate movement of data already in Hadoop to cold tiers within Hadoop, is that right? They would like to setup Hadoop to be a disk library for capturing that long term data, can we do that? https://documentation.commvault.com/2023e/expert/hadoop_tiering_using_hybrid_file_store.html

We have a situation whereby we have some critical content which was pruned from other storage leaving only aged jobs on tape. I’ve been watching the catalog job run for 15 hours and the filemarker is only at 3260 (according to the CVMA.log) and if one can believe this - the end FM of the tape is   139,947,214,372,864 (at least that is what it says at the top of the TapeCatalog.log. Clearly this is a non-starter. The throughput for the last hour(s) is 0MB/s. So, is the FileMarker number real and if so, how could this possibly be a valid solution anymore? Maybe back in the DLT days, sure. Or am I misreading? Support has said there’s no way to estimate completion or progress. The CCM method as suggested in other posts as well as support seems like a possible way, but, I also read that barcodes cannot be the same in source and dest commcells, so then what? And can I choose to simply export or import the metadata specific to this media or set of media? Any suggestions other than waiting an

Hi all,I’m setting up a Synology NAS as a backup repository in a vSAN environment with Commvault. I need advice on the best protocol to use (iSCSI, CIFS, or NFS) for optimal performance and reliability. What are the best practices for configuring the NAS in this setup?Any recommendations would be appreciated.

What is included in the Data Written (TB) figure? Is it only primary copy data written or does it include secondary and third copy also? I know it is already the deduplicated figure that is represented 

Currently, I'm using Commvault V11 SP16. I'd like to know if I can enable the Immutable feature with this version.Does the team have a compatibility document for Commvault versions and their features?

Hello, new install here, needed to make a change on a Cloud Storage (HPE StoreOnce), and needed to recreate the catalyst store. I’ve deleted everything, but now from command center (11.34) I says when recreating the CLOUD Storage is already created. the commvault documentation only refers to commcell operation, but this is strange because commcell is not available on 11.34 https://documentation.commvault.com/2024/expert/deleting_backup_or_archive_storage_policy.html ERRO: Failed to create the Storage Policy [NAME_OF_STORAGE_POLICY]. A Storage Policy with the same name already exists any help will be much appreciated regards

We have the Only Backup Files created or modified on and after option setup for a few servers.  One of our servers is very large video images from our camera system.  It takes up a large amount of our CV Capacity license.  After 90 days we no longer care about files older than that.  I have the Only Backup Files setting set to 90 days from the current date.  The problem is I would need to go in and change that every day to stop it from backing up those older files.  I understand that its not really backing them up however it does count towards our capacity which is very high and we are trying to trim the fat.  My question is can I somehow set that to a date that is always 90 days from the current date when it goes to back up that server each night, or do I have to go in every day and update that date manually?  Thanks for any help.

I rebooted two media agents in my environment and after that, I have DDB verification jobs failing. The error points to mount paths not accessible but all mount paths are online and ready. There are no network blocks. The connectivity between CV and the storage pool is up. The media agents can communicate with CommVault. Backup jobs are running with no issues. Only the DDB verification jobs are failing. The media agents involved are the ones I rebooted
