Storage and Deduplication

Wonder if one subcilent can use different tape media, for example, mixing LTO8 and LTO9 on one subclient. Thanks,S.

Hi,I have noticed aux copies and such taking longer and longer since either moving to 11.32 or 11.36, can’t tell when exactly this started. But now I see loads of decrypt processes running on the MA’s and TTBOMK we’ve not changed copy settings or anything to say “re-encrypt” data, yet that’s what appears to have happened during the leap from 11.28  to .32 and then .36. I hadn’t spent much time thinking of this until recently and now it’s clear the MA’s are spending loads of cycles apparently re-encrypting stuff during aux copies.Does anyone know if some fundamental change was made if you had encryption enabled but same strength that would cause so much extra processing to need to be done?Could it be due to different block sizes on the data paths between the global copy settings?thanks!

As you can see if we enter any random credentials, it is getting accepted. How can we validate that if we provide the original credentials of our HPE Nimble Storage Array, it will integrate successfully with Commvault?  

Hi everyone,If a snapshot of the disk library cannot be restored / reset. Is it possible to simply change the path, or does CommVault need the exact path?Can this be changed at all and does CommVault have a problem with this? Relative or absolute path?How exactly does the restore work if we go back to an older snapshot?What happens to the dedup databases if the disk library is set back by 3 days, for example? Keyword consistency of the dedup databases. I think there is a cleanup process.

After right-clicking on the backup set, checking the data, and proceeding with deletion, no data is displayed.However, when right-clicking on the media storage and selecting "View Contents," the backup data still remains.The storage capacity also does not appear to have decreased, suggesting that the data has not actually been deleted. Are there any additional actions required?

After configuring Data Domain Boost Access library，there is still ethernet traffic through MA when backup.So what can I do to achieve this feature (The Commvault Data Domain Boost Access library type also offers “client direct to device” accelerated backups and restores. Clients can backup and restore directly to and from the Dell EMC® Data Domain® without having to send the data through a remote MediaAgent eliminating additional network transmission).CV:11.32DDVE:7.9

Hello,I have Commvault backup server on simpana version 11.28.68. Also I have Tape library HPE MSL3040 with two Drives..The backup is placed on the tape library. I have a problem two days ago with one tape which was stuck in one drive. I read instruction for Tape library where I immediately had to remove the tape from the Tape library that caused the problem. That tape was in Assigned media. I didn't declare it full, nor did I move it to another scrath pool, I just took it out.Now I have situation that in Assigned media there is display as if the tape exists. but there is label “Not available”. Now, I declared tape bed but still exists in Assigned Media.How can I completely remove the tape from Assigned media?Thank you!Best regards,Elizabeta  

What is the best way to move local disk backups to cloud? We are not going to be using the local disk and need to take it out. 

Hello;We are getting a new media agent, along with a new storage library, and I want to replace the old media agent and storage library. Once I have the new stuff setup I am debating how to replace the old media agent Under every storage policy and plan, create a new copy that writes to the library.  Copy all jobs to that new copy, then retire the old media agent Move the DDB and move the old library mount paths to the new storage library. (https://documentation.commvault.com/2023e/expert/moving_mount_path_to_new_location.html) Just wondering if anyone else has replaced the media agent.  Which method did you go with?

Hello, We have a spare netapp that we want to use as a commvault destination for backup.We have try to use only the netapp deduplication/compression writing directly to the library but the result is only 1% saving, the backup are not encrypted so I was expecting something better. Anyone else has some experience trying to use it. Does commvault store the backup in disk library in a block format that is not compressable even if we are not using the commvault deduplication.  ThanksLuc

Hi!  I’d like to control or set  number of streams for data backup for all subclients and instances in given agent type globally. So for example all postgres subclients are protected using 4 data streams.  Is there a default value that can set during subclient configuration?How to set specific value for currently configured subclients to given value? (other then looping through all clients, all agents, all instances, all backupsets via API). 

Dear Commvault Experts In Commvault Doc, it defines Data Aging as: “Data Aging is the process of removing old data from secondary storage to allow the associated media to be reused for future backups.” Q1:What is “secondary storage” ??If I use an EMC storage, such as EMC VMAX array as a destination to save the backed up data, is this EMC storage array “secondary storage”? Q2:If I set storage policy’s retention to be 7days/1 cycle, as well as enable the “Enable Data Aging” feature,  in or after 8th day, will the backed up data be erased from the EMC storage? Thanks for any hint or direction!

Dear Commvault Experts, My MS SQL AG cluster has a primary replica, as well as a secondary replica,I have create a Commvault client for backup in Commcell, I am curious that,  which AG’s replica will be used as a source that is being accessed by Commvault backup feature?Is it primary replica or secondary replica of AG? Appreciate any help or suggestion!Thanks

Hi community,we have a lot of LTO9 tapes with only few Index Jobs on them (Jobs are in megabyte range) and I would like to re-use these LTO9 tapes (17.58 TB) for other tape-out copies. When these jobs will expire, nobody knows.  Is there any way to copy still valid index jobs to another tape?Pick for refresh, tape to tape copy…?Thanks

Hello All, For the past 2 weeks, we have been experiencing the following issues.All IntelliSnap operations are extremely slow.This affects VMware, Volume Snapshot and Exchange.We use IntelliSnap for this and have NetApp storage behind it. Globally, the behavior is the same everywhere. Locations with OnTap 9.15 and also OnTap 9.11. Not only individual locations are affected, but all of them.Even sites with their own physical media agents.In other words, the error occurs everywhere. We have tried everything. The Commserv is not overloaded. It has 4 socks and 16 cores.128GB RAM. The SQL database is also not busy or extremely overloaded.What steps did I take:- Moved Commserv to another VMware cluster.- DB Maintenance- Installed SQL and Windows updates.Started a job, same phenomenon.Our network team has carried out all kinds of performance tests. No abnormalities.Commserv and media agents are in the same VLAN.The support team has opened 2 cases and filed them under VMware and File Snapshot.

Hello We are using Exchange Mailbox archiving with +10 year retention. For a couple of years we have been using Content Indexing for these jobs, but it’s not needed any more. We have disabled CI and it’s valid for next archiving jobs, but how to clean up previous Content Indexing entries (without deleting archiving jobs)? We would like just to free up space on CI disks as it’s not required any more. As far as I know this procedure - https://documentation.commvault.com/11.20/deleting_content_index_of_specific_backup_job.html - points to Indexing V1 and we don’t have such option in our job history menu. Kind regards,Maciek

Hi Team,I have an interesting scenario.After a lot of persuasion, one of our customers is considering a retention-reduction on non-critical data.But they have asked me if I can work out how much disk space may be returned by this process.The data is deduplicated. So the question I have:-Does anyone know of a report which can show disk space returned for deduplicated data?This might not be as straightforward as it sounds, since I will need to work with 20 or 30 clients, delete data that is over than a few months old but somehow collect details on expected space-savings, or disk-space to be returned.it would be interesting to hear if anyone else has had a similar scenario and how you managed to obtain the figures (if this is actually possible).Thanks

Hi, We are on 11.32.59. We have DDB configured on storage pool with storage as netapp storage grid. We have maximum storage policies with 30 days retention and one storage policy with one year retention.All using the same storage pool..We are planning to enable the WORM storage lock.What is Impact of WORM storage lock on storage growth?I read in the 11.28 BOL that the seal frequency will be set same as Max retention and WORM lock is set to (retention days+seal freq) days.https://documentation.commvault.com/2022e/expert/configuring_worm_storage_mode_on_cloud_storage.htmlWe are trying to understand approximate storage growth on existing library.Can any one please advise.

hi, we have s3 compatible cloud storage and we have multiple customers in a single commcell each with their own cloud bucket. Sometime the space on the storage is reclaimed only when space reclamation is run. According to your document that says - “Use the space reclamation feature to reclaim idle space on non-supported sparse files storage” - how can I find if our cloud supports this or not. Only our disk storage mount paths say “supports sparse” or “not support sparse” but there is no such thing for cloud mount path. Why data aging does not clear up the space and needs space reclamation to clean up. how often should I run this?

Hello guys, I have a question, for tape to tape copy for speed is very slower than disk to tape is this true?here the tape to tape copy is still in 1 library but when disk to tape it gets a throughput of 600-800 while tape to tape is only 20GB/HrThanks

Hi All,What is the easiest way of seeing backup expiration dates across all backups I know you can view jobs against each storage policy and and download to excel but is there not a report that shows expiration date for all backups.Thanks in advance 

Hi dears,I'm searching some info on how Commvault deduplication works and would like to ask: is it correct that the Commvault SQL database MMLibraryHistory table is used to maintain archive file delete records?Thanks for supportgivvi
