Content Indexing (v2) for Exchange Mailbox not needed any more - how to delete Index contents?

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

Forecasting returning space for deduplicated data

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

Impact of WORM storage lock on storage growth

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.html We are trying to understand approximate storage growth on existing library.Can any one please advise.

DDB Space Reclamation use case

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?

HPE StoreOnce Catalyst and Air Gap Storage Compatibility Inquiry

Hi everyone, I have a question regarding the compatibility of HPE StoreOnce Catalyst with an air gap storage solution. Current Setup: HPE StoreOnce - Currently configured as the primary target backup storage and a Catalyst storage. New Addition: HPE DL380 server - Intended to be used as air gap storage. Question: Is it possible to utilize the new HPE DL380 server as an air gap storage solution while maintaining the existing HPE StoreOnce Catalyst as the primary backup storage? Thank you for your time and assistance.

the tape best practices

Hi Guys, i have Quatum scalar i3 tape library, which is connected to the MA via 8 GB FC link. The library has one LTO 8 drive and also the Active Vault licence. what i want ? every friday synthetic backup to tape - i have dedicated 20 LTO8 media in Online, Partition, after backup the media will be exported to the offline partiton in the library. every day bigdata index and DR to the another for example 2-4 media, these media will be online in library and not exported after backup to offline partition, because DR and indexes use only about 20 Gb per day and LTO8 has 11 TB = wasting of tapes. How to configure it ? any advices ?

How to migrate data from Tape media to Storeonce catalyst stores

Hi Experts , I have been task to migrate data from 7 years retention Tapes to our new store once catalyst stores library. The original tape library is already no hardware support and broken and it is also in a different CommCell. after merging the CommCell clients. I am able to see the Tapes storage policy copy ( the primary copy is on a disk storage which is also not recoverable any more.) I am thinking to use aux copy but from console it seem I can only copy the tape to another tape using the new tape library on loaner for migration purpose by HP. Is there a way to use the loaner tape library read the tapes and direct copy to the Store once catalyst stores?

Index Cache filling up: Intellinsnap incremental backups without full

We have incremental backup copy jobs failing due to lack of free space during index restore; I was reviewing the Index cache and noticed F:\IndexCache\CV_SnapMetadata\2\3568\1737471697 showing over 239GB of metadata. From what I understand this folder will have all the indexing metadata from all the Intellisnap incremental jobs; this specific job have not had a full backup(I am investigating the reason) for some time. If I were to take new full backup what will happen during the backup copy; would it still try and restore historical incremetal index data as historical incrmental backups have not copied across or because this is a new full it will only copy the most recent backup copy. What if I manually delete the old snapshot and just keep the most recent would that avoid incremental backup copies and just copy the full backup without restoring index and would it clean up this metadata

Adding new media agent to existing environment

Hello Guys, I will be adding a new media agent to our existing comcell environment. After installing commvault software on the new media agent and sharing the mount paths of the disk library with the new media agent. Will the storage policies associated with this disk library be updated automatically to include the new media agents in the "data paths" tab? Or should I manually navigate to each storage policy and add the new media agent in the "data paths" tab?

How to find details on Metallic cloud storage

My Aux Copy jobs going to Metallic cloud storage have been stopped for the past three days. I’ve asked my network team if there are any issues and they are asking for the connection information. I can see my on-prem media agents easily enough but can’t seem to find any of the details for Metallic. How do I find network details on the Metallic cloud storage?
