Storage and Deduplication

Dear Community,  when is it planned to introduce support for LTO-10 Tapes? Best regards, Aleksandra 

I find all jobs in waiting state e the volume offline.I restart Media agent and the volume comeback online, but the jobs stay in waiting mode , then I try to restart the comvault server (LIUX - Roky), but the server don’t start anymore and in boot screen appear the fail error : Failed to start D-Bus Dbus system message BUS.

Hi,Currently running HyperScale 1.5 which is EoL end of the year. With the current elevated price of hardware am looking into using AGP instead. At the moment the DDB and Index is stored on the HyperScale nodes. What options are there for hosting the DDB/Index when the HyperScale nodes are decommissioned?thanks in advance for any response/advice. 

Dear Support Team,Kindly be informed that we are currently experiencing a backup error. Some of the servers are not completing the backup process successfully.Could you please investigate this issue and provide your support and advice on how to resolve it?Your prompt assistance would be highly appreciated.Thank you for your support.  

Hi everyone,I have the following environment: Commvault: v11.40.42 Tape drive: HPE Ultrium LTO-6 standalone tape drive I have a specific requirement and would like to know if Commvault supports this.I do not want to manage tape retention, tape order, or manually track which tape contains which backup.Instead, I want to configure a scheduled time (for example, every Sunday at 12:00 AM) so that when a tape is inserted into the standalone tape drive, Commvault will automatically delete/expire/erase all backup data on that tape at the scheduled time.For example: Tape is inserted into the standalone drive. The tape contains backup data from previous backup jobs. At the configured scheduled time, Commvault automatically removes/expires all backup data on that tape. I can then reuse the tape for new backups. Is this possible with Commvault v11.40.42?If it is possible, what would be the recommended configuration or workflow for a standalone tape drive?I'm specifically looking for a sol

My understanding is that the deduplication database is not used in a restore scenario.  Many years ago, I ran a restore without a DDB or IndexCache.  It had to rebuild the IndexCache as it went, and was terribly slow, but it worked.  I found some posts on here saying the same.Is there any official Commvault documentation that states this explicitly?Thank you!

Hello Team,We are currently using HP LTO7 and LTO8 media with our Commvault environment.Could you please advise if there is any recommended limit on the number of times these tapes should be reused? Also, are there any Commvault or HP best practices regarding tape media reuse, such as a recommended maximum number of write/overwrite cycles or media retirement criteria?We would appreciate your guidance on the recommended approach to ensure media reliability and avoid any potential data integrity issues.Thank you for your support.

Hello guys,we have installed a new Commvault environment for a customer a few months ago. The customer now says he wants encryption enabled for all backups. I found the option “Create new DDB every 30 days” in the deduplication engine settings and was wondering if that can solve our problem.In my understanding, this option will write every backup after 30days as new blocks which also should make them encrypted. So my question is:can I just enable encryption on the DDB engines and check the “Create new DDB every 30days” box and keep everything else running? Will this solve our encryption problem? Thanks in advance

We want to migrate jobs from one S3 cloud library to another S3 library without DDB, avoiding the use of auxiliary copies or data path moves. We aim to use an internal bucket-to-bucket copying mechanism to avoid standard data egress and ingress—thereby reducing egress costs, even though the transfer itself will still incur a charge. Once the data has been copied, we will import the metadata to ensure the backup chain remains consistent for future restores.

Hello all!In our environment, we have created a temporary copies within our few storage policies - (call them copy 6 and 7). Those were tape copies. We have keep some backup there for 2 months, but it is no longed needed. We do not need those copies within those storage policies any more. But for now, even if they are no longer any backup retained on this 6-7 copy, we do have a lot of “Big Data Apps” jobs retained on those copies.We would like to delete those copies because it interferes with our “workflow” which picks jobs for copies and it's keeping to mark them to copy for 6-7 copy. (even if copy is disabled) So my question is - what exactly this Big Data Apps is? It is some kind of Index, am I correct? If those “Big Data Apps” are stored on copies 6-7 are there any dependencies for other copies, other jobs keep in other/same storage policies?Can we just delete copy 6-7 from our storage policies even if they are still those Big Data Apps stored on it, and it won't affect the rest of

How can Commvault be configured to write backups to tape media? (Note: I have already added the tape and can see the drives and media; I have two drives and three tapes, as well as two backup plans. However, while one plan always succeeds, the second consistently results in errors [32:690] and [32:193].) 

how make the commvault write backup on tape media (note: actually i added the tape and i can see the drives and tape media and i have 2 drives and 3 tape media and i have 2 plans but one plan only that always is success job and the plan number 2 give me error [32:690] , [32:193] ) 

Hello,I would like to ask a  question about cleaning the local on-prem S3 storage (Netapp AFF C30).We have two buckets created (two mount path’s). Both have micro-pruning enabled from the beggining.On Mount path “General” informations I can see that:bucket1: Size on Disk: 90,68TB / Estimated Media Size: 68,06TBbucket2: Size on Disk: 86,86TB / Estimated Media Size: 65,77TB I had similar values in the past on Commvault (MCSS/MRR/AGP) cloud storage - and after running Space Reclamation - we were able to free up a lot of space.Should I run a space reclamation here on this S3 storage? Is micro pruning sufficient way for cleaning on-prem S3 storage in commvault? or maybe we should run this space reclamation from time to time?It would be great to hear what best practices are.Thanks in advance.Regards,Matt

Hello, guys  I want to perform a secondary copy to tape, and be able to write the data to tow tapes at once, Same data must be written to tow different tapes that belong to two different pools (main pool and copy pool). The idea is to be able to have mirroed data on tapes that will be stored on different sites (customer policy). Data must be read once from primary store (source) and write at same time to diferent tapes.Customer has a library with 3 drives. Any idea?Regards.  

Hello everyone,For the past few days, I’ve been working with a Commvault engineer to disable the compliance lock on the Storage Policy. There was some obsolete data that wasn't expiring—possibly because we didn't have secondary copies, or because some items were linked to other data that hadn't yet completed its lifecycle. Anyway, the data was deleted, but the change wasn't reflected in the storage yet. To be certain, is it best to validate this via the library or the Storage Pool? Could you please advise?

NetApp is currently selling the successor to the ASA (SAN Only), the ASAr2, at an attractive price. Basically, it is a system from the ONTAP family, like the FAS or AFF systems. Unfortunately, the API has changed considerably, and Commvault does not yet support the ASAr2 API. I’ve heard that integration is being worked on. Is there a timeline for this?We have a few projects where Commvault (new customer) and NetApp would be a good combination.

I have a customer running 11.40 and Commvault now has the combo tiers for cloud storage configured by default. My question resides in which tier the bucket should be created. The customer had previously created a bucket in AWS (this may come into play later) that was used to create a Cloud Library in Commvault using the AWS Glacier Deep Archive tier. When examining the data in the bucket, we can see the CHUNK data is written to Glacier Deep Archive however, the index metadata is showing under Glacier Instant Retrieval. This seems wrong to me.I have read that Commvault will apply an Amazon storage class header to every upload API call and then writes the data to the bucket, which is part of what is allowing the CHUNK data to be written to one tier with the index metadata to another tier. I’m starting to believe that the storage class header only is being applied to the CHUNK data and the metadata is using whichever storage tier the AWS S3 bucket was created with. Documentation doesn’t m

Hi all,just wondering if anyone can help me. I’ve noticed on our Hyper-V hosts then when a backup is triggered in CommVault the system event log on the hosts are flooded with Disk and partmgr warnings for specific disks.I’m just wondering if this is normal behaviour or something we need to look in to? For context, these hosts are running Windows Server 2019, are MediaAgents for all our VMs and we are running CommVault version 11.36.102.The disks presented to the cluster are CSVs and are presented via iSCSI from our NetApp.I cant see that its causing any hard to the backups as they are completing successfully. The Vms and hosts also appear to be fine - but not sure what could be causing these warning or how to remediate them. 

I was teaching a CV Engineer trainingsome time ago, using a lab setup for demos that I upgraded from 11.32 to 11.40. I created a disk storage pool to demo things. When I started to configure dedupe, I only got the possibility to choose the MA for the DDB, not the location (vloume / folder), so the DDB ended on the C: drive. Is this because the upgrade went wrong, or is this by design? If it's by design, why???

Dear Community,Perhaps anyone can answer me the following question. My customer use storage accelerator (SA)  for backups and Aux copies to cloud. Now he asked:How can I easy see that SA was used or not?We are at 11.36.55. First, I asked Arlie but answer seems only partly correct. I am still at the beginning to check all points Arlie told me. Java GUI is not useful in this case. It shows allegedly only results if SA is used. To make a clear statement, I always must check the log file.In the command center, I must differentiate between backup jobs and Aux copy jobs.Backup jobs indeed have a line: storage accelerator yes/no which is the expected behavior.According to Arlie, there should also be a line for Aux copy jobs that clearly indicates the use of SA.I am not able to find. Can you help?My customer needs a clear indication on user level that shows if an aux copy uses the SA or not.We currently analyze logs or the network traffic to get clear results which is not useful. Thanks in adv

Hi everyone,I'm looking for some advice regarding a tape backup issue in Commvault.Environment:    Commvault Web Console v11.40.42    HPE Ultrium LTO-6 standalone tape driveThis tape drive was previously used in another backup solution. Before using it with Commvault, I:    Stamped the tape media.    Used the Delete and Reuse option to erase the existing contents.    Set the tape as Primary media.    Started a backup job.The first backup completes successfully and writes about 1.16 TB of data. However, after the backup finishes, the tape media is usually marked as Unavailable, and sometimes it is marked as Full.From my understanding, an LTO-6 tape should have a native capacity of around 2.5 TB, so I'm not sure why Commvault considers the tape full after only about 1.16 TB of backup data.When I start another backup job, Commvault prompts me to insert a new tape instead of continuing to write to the current tape.I also noticed the following:    If I power cycle the tape drive, the tape a

Good day to you all,I am experiencing with our Dell EMC PowerScale NDMP IntelliSnap backups across our two CommCell environments.Context: We have two CommCell environments configured to back up Dell EMC PowerScale shares to a HyperScale target. Currently, the shares are split between the two CommCells.The Issue: While the snapshot backups for both CommCells complete successfully, the Backup Copy job for CommCell 1 is consistently failing.Upon investigation, we identified that for CommCell 1, the data movement from the PowerScale server to the MediaAgent is defaulting to a higher-end port/interface instead of the expected 10000 port. Interestingly, CommCell 2 is configured similarly and is performing its backup copies without any issues. Kindly advise on this. Robert.R

We recently migrated our Commserve to a new physical server and now several weeks post migration we are getting errors on about 90% of our synthetic fulls when they reach the end of the job, they will continously run at 99% but looking at the synth full logs we see alot of this:30236 5280 06/05 12:34:18 13071395 SdtDecryption::ProcessBuffer:218 Cannot decrypt data for afid [28434509]. cur_afid [28725857], orig_afid [28434509]30236 574c 06/05 12:34:18 13071395 SdtDecryption::ProcessBuffer:218 Cannot decrypt data for afid [28434509]. cur_afid [28725857], orig_afid [28434509] The event viewer gives the generic Unable to communicate with Media Agent or Pipeline error. Opened a high priority ticket about a month ago and we’re being told we need to seal every DDB store in our environment and re-base. We have several thousands of VMs with some over 60TB in size. I feel like re-basing is going to take weeks, and we may not even have enough storage to do it. Any other thoughts or ideas would be
