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?

Detecting data inside of a mount point/disk library not associated to active backup data?

Hello there CV community, We are in a situation where we expect there may be some data in one of our disk libraries that is not associated to retained backup jobs. The jobs data stored on this disk library utilizes deduplication, so primarily the folder data contains deduplication chunks. We would like to validate that the content on the disk library is “current” i.e. associated with retained & deduplicated backup data. In this case, the storage is Azure object storage. Based on Damian’s post here: Clean Orphan Data , what is it? | Community (commvault.com), our hope was that we could use the DDB space reclamation feature alongside the ‘Clean orphaned data’ option to do this automatically. To test this, I ran the operation in a test environment after having stored some arbitrary files alongside legitimate backup data within the storage. This wasn’t successful, and I expect I have either misunderstood his description of the functionality or perhaps Commvault is specifically looking for

Error when adding Oracle Cloud Infrastructure Object Storage on Command Center

May I know if anyone encountered this error before when adding cloud storage on Command Center? May I know what is the resolution? I tried to search to any sites but got not luck Error below: "Operating System could not find the device file specified. The device may be unreachable from the MediaAgent. Please ensure that the file is present in the given path and is accessible."

Benefit to enabling Horizontal DDB

Hello, What are the benefits to enabling the horizontal DDB, BOL explains how enable this feature, but nothing about the real benefits except that split the DDB in 3 section first for File system, another for Database and the last one for VM. Can I expect to see an improvement in backup performance or an increase in deduplication performance that would further reduce on-disk consumption? Thanks,

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!

New E2812/Media Agents recommendation

I’m slogging through a CV hardware upgrade. My company is “trying” to find $$ for training...but so far no joy, so I’m winging it. I have a new NetApp E2812, two new media agents, and a shiny Brocade FC switch to bind them all together. My immediate question is, do I create two volumes on the E2812 and mount one on each MA? Or can I create just one volume and let both MAs read/write to it simultaneously? Typically, sharing a volume like that across multiple Windows servers leads to trouble, but can the CV media agents handle that sharing? I like the idea of a single volume letting both MAs access all of the available disk space. That alleviates the need to balance my backups across the different volumes. Does anyone have any helpful pointers for me? Much obliged.

Reporting CLI

Good afternoon, I am trying to create a report on the occupancy of our libraries. However, the report coming from Commvault has a lot of information. Would it be possible to use CLI to extract only the information I want? My idea is to create a script and run it every month without having to manually organize the data.

Clarification on Deleting Jobs on Tape

Hello, I am updating some our documentation on our best practices to securely delete files from file server's backups. The file server backups in questions are only stored on a primary copy residing on tape, encrypted via AES 256 per the storage policy, and using the built in key management server. Normally if we need to delete a file, we follow the documentation and use the delete data by browsing option. For clarification, if I use the "delete data by browsing option" and delete a file that resides offsite on tape, there is no way to recover that file, correct? There is no way to "Un-Age" or catalog operation on the tape I could perform if I were to insert it back into my tape library? I assume that the CommCell destroys the indexed data/encryption keys associated with that file and cannot read that block of data on the tape? Recently I noticed an option in the CommCell browser where I can delete content of an entire tape. Storage Resources > Libraries > Tape Library > Media By Locat

DDB threshold reached max limit

Hi Team, The DDB partition Q&I time is very high post changed the DDB partition location. I have moved the DDB partition recently from one drive to another due to space was full. As per storage team, we are using Lun assigned NLSAS_SSD drives on our MA. Now all the backups are running very slow. I want to reduce the Q&I time or else want to run the DDB on single (T:\ DDB) partition. because the backups are running fine using that DDB(when i was moved the DDB that time it was used another partition) Please suggest on this. I have raised a case to vendor, they are suggesting to run the ConvertDDBToV5 workflow job and waiting for the steps and DT.

DDB reconstruction

Hello, During a DDB reconstruction process, how does it reconstruct the missing data? In our case, it first performed a restore of the last backup which was from sometime early morning. Does it then access the library storage directly to reconstruct the missing data or does it access the Commserve? I’m asking because I’ve been told conflicting information from different Commvault technicians. I just want to make sure that I understand this process clearly. Thank you. Bill

Restore from Combined Storage Tier Cool/Archive

Hi All, I have question regarding the Restore process specially for the VM Gues File system restore when done from the combined Storage Tier Cool-Archive being as used as end for long term Library. As understand, the Index and Meta data in this case will be in Cool storage and hence we would be able to Browse the data without having to run the recall workflow. Having selected the folders to restore, will the complete VM data/disk data be rehydrated from archive to tier or just the selected data?
