Space reclamation / orphan data cleaning against cloud storage library

Hi all,Wondering if by chance anyone has experience running DDB space reclamation with orphan data cleanup against a cloud library. We have a cloud library in Azure cool tier which we expect may have some data that was not pruned successfully, thus increasing our storage consumption in Azure. The deduplication database for this data lives on local storage.We’d love to run a space reclamation with orphan data cleanup against this cloud library, but we’re concerned about the possible cost of storage transactions against the Azure cool library.Has anyone performed this operation before and observed the related cloud storage costs? For reference, we have just under 100 million blobs and a total of about 400TB of storage utilization in Azure. Many thanks for any input folks may have!

Additional tape library slots are not being detected

Hello!Customer has this TL that is partitioned. There's a partition for Commvault. Originally it had 11 slots and some drives.Customer added 30 slots but they don't get recognized by Commault (and so the tapes on them).Full scan does not update the slot count.What must be done to recognize the new added slots?Regards,Pedro

Aux Copy - Determining if Disk Read Optimized Copy or Network Optimized Copy is being used

Hi Community,With reference to the following post where there is no longer an option to select:https://community.commvault.com/topic/show?tid=5967&fid=49Is there a way to confirm which option is being selected for an Aux Copy Operation?  I would like to confirm because I would assume that when copying between 2 cloud libraries, Disk Read Optimized copy would be more efficient and cheaper in cost being that each block does not need to be read to generate the signature - or at least that's the way I read doco.  Would there be an entry in logs to determine this?Thanks in advance for the advice/assistance.

Hyperscale nodes reporting low disk space on Deduplication DDB path

New to Hyperscale nodes and trying to figure out how to increase the size available to be used for the DDB paths.We have multiple GDSP's using the HS for their DDB's and are receiving warnings that the free space on DDB MediaAgent is very low.Looking at the disk space it looks as though there is 1.4TB left on the mount path. I'm a windows person so maybe I'm not understanding?Is there a way to give more space to the DDB’s? Thanks

Multiple Job Failures: "Mount path does not have enough space"

We’re using Commvault v11.28.48 and have several jobs that are in a “waiting” status and sitting at 10%-20%. The reason is simple: Mount path does not have enough space.I’m new to Commvault (our backup admin left recently and I wasn’t involved in the initial config or daily use) so I may be missing something obvious, but I thought aged data would be deleted automatically. I’ve run the “Data Retention Forecast and Compliance Report” and see the various estimated aging dates, the only thing that sticks out is the last line under the Disk Media Summary:Estimated Size to Free: 9406 GB (this box is green: “prunable job / recyclable media”) Delay reason for physical space cleanup: Archive file has been queued for pruning from the DDBOur Netapp library is 24.7TB with a size on disk of 24.46TB, reserve space set to 100GB, so an extra 9TB would be great. “Enable pruning of aged data” is checked on the library.Am I correct in thinking that 9406GB is data that should be automatically removed (pru

Can a StorageGRID synchronous aux copy have a vault/replica as a source copy ?

Hello Team. I have a storage policy with a snap primary which snaps a netapp a700, and a vault/replica (not a mirror) that CV orchestrates the replication between the a700 and a fas8700. There is a primary copy as well but I don’t want to use this as the source copy for the storagegrid copy; i want to use the vault copy as the source copy for the storagegrid copy. I am creating a new storagegrid synchronous aux copy and the only options to pick for source copy are primary and storagegrid.  The only configuration I can figure out that works is to have a primary copy, which copies the snap primary copy, and to choose the primary copy as the source copy for the storagegrid copy. Is this expected behavior of the program ? Is there any way to configure the program so a storagegrid copy can have as its source copy the replica/vault copy ?Thank you!

HyperscaleX DNS requirement

Hi Good Day!I’m planning to deploy new HSX servers. I have a question about the DNS record requirement. Pls help.Environment detail:Bond1VLAN1.bond1 (CS-Registration)  -→ This will be used for connecting to Commserve and VMware backup, DNS, and MGMT.VLAN2.bond1 (Data Protection)-→ This will be used to backup Agent-based backup. Bond2 -→ This is for the Storage Pool.

Tape Library Drive Troubleshooting

Hi,I have so far replaced three drives in our DELL/EMC ML3 Tape Lib and still experiencing the same problem. Currently, there’s one valid drive that is working fine - when it comes to the other one, it is mounted and immediately unmounted after a couple of seconds - one try after another in an endless loop.According to DELL, there’s nothing in the library log that would indicate the root of the problem (the log is clean) - they send me another drive and then the case is closed until the issue rises again.I tried swapping the drives in slots but the problem is following the same drive no matter the slot. At this point, I’d like to exclude software-related cause of the issue.Currently, the number of errors associated with mounting and unmounting the drive is way over its threshold; that might be the reason why CV is ignoring the drive completely - how can I reset the counter? Is there a particular procedure I should follow when replacing a drive? I can see there’s an option ‘Mark drive a

WORM storage lock with DD

WORM Storage lock with datadomain

Hi we are running 11.30 and we want to start testing WORM Storage capabilities on our Datadomain. We have configured the retention-lock feature on Datadomain and activated the WORM Storage Lock on Commvault through the CommandCenterTalking to the Dell specialist, he has told us that there is a config that could affect on Commvault, the “automatic-lock-delay” value. That´s the time that the file remains “opened” while are being written on the DD by the backup aplication (in this case, Commvault), until it confirms the file closure and the it locks the file with the retention set before. As we don´t know how much time does CV need, we have set it to 120min on the DDHas any of you any experience with WORM on Datadomain in Commvault? Do you know how much time does Commvault keeps the files open on DD until are closed?

StoragePolicy tiering or moving backups older than 6 months to different storage

Hello community,We have Storage Policy which keeps all backups for 30 days and monthly backups for 18 months all on the same storage.To free up some space, we could create another copy pointing to the cloud to keep our monthly backups for 18 months. Then we would have 30 days on prem and all monthly backups in the cloud.Now, a new idea has come up to keep 30 days on prem as well as 6 months for monthly backups.And when the monthly backups are 6 month old, the should be copied to the cloud until they are 18 months old and removed on prem.Is there a way to delay the copy of the monthly backups for 6 months?

What is the proper process for changing KMS servers for backups? (Built-in to Azure Key Vault)

Currently our client is using the built-in KMS server which stores encryption keys in the Commvault Database. As far as I can find, there is no way to extract these keys.We are looking to transition to Azure Key Vault for storing these keys. It is very easy to change the KMS server, but in theory this would leave us unable to access the previous backups as we technically do not have access to those keys for decryption.I have searched this extensively and there is no documentation for this (confirmed via Commvault support phone call). What is the proper process for changing the KMS server on a backup location, particularly the built-in KMS server over to a third-party, without losing access to backups? I did find 1 forum post stating this “just works”, but I need to provide some kind of concrete answer for my higher-ups to be happy. Thank you in advance!
