Storage and Deduplication

HiI would like to execute a secondary copy from a S3 bucket to another secondary copy S3 bucket. I created and configured buckets and its working. But the issue is the mediaagent is in our local infraestructure and data travels a lot instead of going to bucket to bucket directly is any way to configure this ease or i need to put a MA in our AWS infraestructure instead of locally? Thanks!!Joan Mas

We are experiencing issues with our HyperScale cluster. Backups seem to be working, but we are getting the following error message during backup:Description: [Media write operation failure] [Dedupe disk media] [The request could not be performed because of an I/O device error.]Source: SRV1092b, Process: cvdAt first it seems to be disk space in hyperscale, but I would like to know if there is any documentation talking about the limit space required to operate hyperscale.

Hi all,we need to extract some useful information from our commserve: we would like to know the total number of files (or jobs if number of files is not available) that have a retention greater or equal to 6 months and are stored in our libraries.Is there an SQL query or a report that can give us this information ? I don’t want to perform several queries on all the different storage policies that we have, I just need the numbers (if available).Any suggestion is appreciated,RegardsGianluca

Hi,Is it safe to run space reclamation with clean orphan data option checked when using cloud library and s3 buckets shared by multiple pools/DDB’s from different grids? Or will it clean the data from the other pools as there are no references to that data in the DDB being cleaned?Thanks

Hello,we have scenario that we have two Media Agent in an OnPrem Location for customer.ma01 is used for infrastructure Backup mainly VSA Backup etc.(direct connection to CS)ma02 shoud be used for Agent Backup (SQL ;SAP etc..) in Customer Network (direct connection to Clients / Connection to CS via Topology)ma01 with VSA Backup is working fine.ma02 if we select manually for Agent Backup also works fine, but for scheduled Jobs always ma01 is selected and not ma02.So we found following Additional setting:https://documentation.commvault.com/additionalsetting/details?name=PreferredMediaAgentGroup“ PreferredMediaAgentGroup“We activate this Additional Setting on both groups for MA and Agents with same value “ma02” but it does not

Hi, Was wondering if there’s a report I can use that will list server, database and all the restore points we have available. I know I can go into each database recovery in the portal and use the calendar but we have 5000+ databases so looking for the raw data if poss. Something like this would be great, if it exists.   Many thanks 

We are experiencing a behavior only in some full jobs of a particular schedule, this happens in protected objects, the error messages are Remote I/O error, what we have detected is that the next incremental backup takes the objects that marked error in the full backup, we have moved the schedule backups but the failure continues, the backups are directed to disk libraries, has anyone had this behavior that can help us solve it.

Hello All,I’m a newbie, starting with CommVault and see these “Event Codes” on a Data Aging Job every day.Event ID 97531656 Event Code 13:6 (Exiting with errors - some files may not have been pruned) Event ID 9753162  Event Code 13:48 (Data is partially pruned due to database problem)As stated, I’m a newbie at this and don’t know if there is something I can do about this or should do about this.Any insight would be great.TIA, AlanKeno

I have a question about encryption for networks and media. I'm not sure what type of encryption it is, such as AES or Blowfish. Could you provide an answer? 

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

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.  Lo

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.

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

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. The CS, MA and VSA are in same subnet and the VSA has direct connectivity to DD Boost Client Library. 

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]. The parameter used for the current operation is not supported by the Operating ssytem, OD Drivers or the underlying Hardware. Source: [XXX], Process: [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
