We currently have a 3 node Powerstore cluster deployed and we are looking to leverage the internal Powerstore cluster data migration to move a volume and all of the volume snapshots between arrays in the Powerstore cluster.As these snapshots were taking by CV IntelliSnap and not committed to the Isilon were we keep backups yet can we still go ahead with the migration and well not break anything?I can’t find anything in the documentation that can support this question either way, but any feedback would be awesome!
Hi Team, From what I can see in the document, in the Commvault FR20 version, it is possible to discover NAS systems live and get a report. However, I think this feature is obsolete. Is there a feature that can discover NAS systems live and provide a report with the 11.32 version? https://documentation.commvault.com/11.20/nas_system_discovery_report.html
I have a customer who has excess Hadoop capacity that they would like to use for a long term storage target. I saw the below link on BOL that caught my attention as a possible solution, but I think this is just using commvault to orchestrate movement of data already in Hadoop to cold tiers within Hadoop, is that right? They would like to setup Hadoop to be a disk library for capturing that long term data, can we do that? https://documentation.commvault.com/2023e/expert/hadoop_tiering_using_hybrid_file_store.html
We have a situation whereby we have some critical content which was pruned from other storage leaving only aged jobs on tape. I’ve been watching the catalog job run for 15 hours and the filemarker is only at 3260 (according to the CVMA.log) and if one can believe this - the end FM of the tape is 139,947,214,372,864 (at least that is what it says at the top of the TapeCatalog.log. Clearly this is a non-starter. The throughput for the last hour(s) is 0MB/s. So, is the FileMarker number real and if so, how could this possibly be a valid solution anymore? Maybe back in the DLT days, sure. Or am I misreading? Support has said there’s no way to estimate completion or progress. The CCM method as suggested in other posts as well as support seems like a possible way, but, I also read that barcodes cannot be the same in source and dest commcells, so then what? And can I choose to simply export or import the metadata specific to this media or set of media? Any suggestions other than waiting an
Hi all,I’m setting up a Synology NAS as a backup repository in a vSAN environment with Commvault. I need advice on the best protocol to use (iSCSI, CIFS, or NFS) for optimal performance and reliability. What are the best practices for configuring the NAS in this setup?Any recommendations would be appreciated.
What is included in the Data Written (TB) figure? Is it only primary copy data written or does it include secondary and third copy also? I know it is already the deduplicated figure that is represented
Currently, I'm using Commvault V11 SP16. I'd like to know if I can enable the Immutable feature with this version.Does the team have a compatibility document for Commvault versions and their features?
Hello, new install here, needed to make a change on a Cloud Storage (HPE StoreOnce), and needed to recreate the catalyst store. I’ve deleted everything, but now from command center (11.34) I says when recreating the CLOUD Storage is already created. the commvault documentation only refers to commcell operation, but this is strange because commcell is not available on 11.34 https://documentation.commvault.com/2024/expert/deleting_backup_or_archive_storage_policy.html ERRO: Failed to create the Storage Policy [NAME_OF_STORAGE_POLICY]. A Storage Policy with the same name already exists any help will be much appreciated regards
We have the Only Backup Files created or modified on and after option setup for a few servers. One of our servers is very large video images from our camera system. It takes up a large amount of our CV Capacity license. After 90 days we no longer care about files older than that. I have the Only Backup Files setting set to 90 days from the current date. The problem is I would need to go in and change that every day to stop it from backing up those older files. I understand that its not really backing them up however it does count towards our capacity which is very high and we are trying to trim the fat. My question is can I somehow set that to a date that is always 90 days from the current date when it goes to back up that server each night, or do I have to go in every day and update that date manually? Thanks for any help.
I rebooted two media agents in my environment and after that, I have DDB verification jobs failing. The error points to mount paths not accessible but all mount paths are online and ready. There are no network blocks. The connectivity between CV and the storage pool is up. The media agents can communicate with CommVault. Backup jobs are running with no issues. Only the DDB verification jobs are failing. The media agents involved are the ones I rebooted
If we back up a new server one time and let's say it is 15 TB. We then release the license for said server, how long does it take for that for that 15 TB to return to the license? Is it based of the data aging jobs that run, or is there a certain number of cycles Commvault goes through to make sure the 15 TB is never going to come back?
Hi All,One small query, generally during VM based backup, commvault creates disk snapshot in azure - OS disk snapshot.Is it possible to create VM directly from the Azure portal using commvault created OS disk snapshot - likecreating disk from that commvault snapshot and build VM using the new created disk.is this approach feasible, or can it be restored using commvault tool only.
We are implementing a new StoreOnce system as primary copy and test performance (and other topics) between FC-catalyst stores and FC-Virtual Tape Libraries A Catalyst Store on StoreOnce can be configured either as high-bandwidth or low-bandwidthhigh-bandwidth: Backup server (media agent in case of CommVault) will send backupstreams unmodified to StoreOnce and then StoreOnce will do dedupe etc. before finally storing the data on its disks. low-bandwidth: already the backup server (media agent) will do de-dupe and only sends new things to the StoreOnce.VTL is similar to high bandwidth (all goes from MA over FC-SAN to StoreOnce and only there the data reduction takes place). As we have plenty of ressources on FC-SAN and the StoreOnce is made for doing all the datareduction we’d like to get StoreOnce connected/configured in high-bandwidth for Catalyst, especially as important servers are doing LAN-free backups (have their own media agent locally installed to directly backup over FC) - havi
