DiskLibs: SMB or iSCSI attached volumes for the mountpath?

Hi all,any advantages, other than security with removing attack surface, when using iSCSI attached volumes from a NAS directly to the Windows MediaAgent rather then writing via SMB to the NAS share?In regards of performance, ransomware protection etc?Your thoughts are highly appreciated, thanks in advanceregardsMichael

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

MCSS Library performances

Hello, I have a matter that could require some help.We have a primary copy on a disk Library, a secondary on another disk Library and a third copy on a MCSS cloud Library. All copies have dedup enabled.Auxiliary copies run fine between the disk librairies but when it comes to sending the data to the MCSS library it takes forever. We tried to increase the number of streams, use either of the disk libraries as source for the aux copies but we can’t achieve suitable performances. What we see is that the process generate excessive read operations on the source library. Dedup block size is 128 on the disk libraries and 512 on MCSS.Commvault version 11.24.Any help would be appreciated.Regards, Jean-xavier

how to create metallic license library capacity dashboard widget

We have CommVault Complete licensing and also Metallic Cloud Storage Service (MCSS) licensing. However, the Command Center dashboard lacks a widget for Metallic. Can someone share how to add a widget that would display the %used of a library? This would effectively show MCSS as a % of licensed use. The existing Current Capacity widget only shows the % of licensed Complete usage, not the % of storage used; the MCSS library falls into the latter category since MCSS is not a “Complete” accounting of backup potential, it is an actual % of backup used. From dashboard:From Storage>CloudSo it would be nice to see the cloud library as a pie chart, similar to the complete licensing in the Current Capacity widget. How do you make widgets and put them on the dashboard?

Command Center - Adding Tape Library doesn't allow for other scratch pools? Barcode patterns?

Someone on my team wanted to try to add a new Tape Library to the environment using Command Center. I had never done this in Command Center before, so I watched the user go through the steps. We found that it had created the library and the storage pools. But we could not find any way to create barcode patterns or to create another scratch pool from the Command Center.We are an MSP and this is an essential step in being able to use the library.We then tried to create the barcode patterns and other scratch pools from the CommCell Console. We created the entities but then found we could not associate it to the pool/plan.It appears that the option to change the scratch pool is greyed out in this case.Is it expected that you cannot edit the scratch pool when the library/storage policy/plan is created from the Command Center? Or are we missing something here?Furthermore I was expecting a much more user-friendly approach to adding tape to the environment. For example, the user had to s

Tape library - 3 week sets

Afternoon allI have a few questions - hopefully nothing too complicated!I have recently configured a tape library in our Commvault environment which appears to be working OK - I just had a few questions around configuring the tape library to suite our needs.The plan is to backup to tapes so they can be take offsite daily and used in a DR scenario. We would like to keep 3 weeks worth of data on the tapes and would like to have a tape for each day.I’ve configured the auxiliary copy job and the related schedules to backup at a suitable time which I think so far is fine however where I appear to be struggling is with configuring Commvault to backup to a new tape each day.We will have 21 tapes and as an example tape 001 will be week 1 Monday, tape 002 will be week 1 Tuesday etc - tape 007, 008 and 009 will be Friday, Saturday and Sunday respectively.There will be x2 SP’s that will be backing up to tape - my question is, is it possible to configure CV so that one the backup job from SP2 is c

C0000000.js file created in backup disk folder.

This file was created in one of the backup chunk folders of our deduplicated disk backups on a media server and was flagged by antivirus. The file no longer exists and I’m certain this was created (and subsequently deleted) by Commvault to script some sort of storage/disk operation but was curious if anyone could confirm. Thanks.

Rescanning cloud storage

I am testing commvaults connection to Wasabi.My Wasabi test bucket is object locked, so Commvault can’t delete older data. To test a loss of commvault database I didn’t configure my commvault jobs to be worm protected.Consequentially, I was able to delete some jobs, although the data in the Wasabi bucket remains.I can’t seem to find the option in Commvault to scan the bucket for existing backups to reimport.Is this not available?

Aux Copy Job missing ?

Hi, I have a customer with 2 copies :1-Primary dedup on disk with 66 jobs.2-Secondary dedup on disk with 133 jobs He created a copy 3 to replace the secondary but he chose #1 for the source, but there are jobs only in the secondary copy, is there a way to pick the missing jobs by changing the source of copies #3 for source = #2 ? If I change it and run and Aux Copy the missing jobs are not picked ? Or I have to delete the copy #3 and start over !?

DDB Verification in amazon glacer

Hello all, I have an auxiliary copy with deduplication running to a Glacier and i would like to run a DDB Verification on it, just to see an estimate cost for future verifications.What i would like to know is how do i use the workflow Cloud Storage Archive Recall for every job id that is referenced in that DDB, since in the workflow window it makes me choose a backup job id.

Both with data in them.We’ve found this can be done in version 11.32 https://documentation.commvault.com/v11/essential/157074_moving_backup_location_to_new_location.htmlCan it be done in 11.24.116?If so, where do we find the function?If not, which version must we upgrade to? Any thing to consider prior to upgrading?

ddb disks run out of space, what can I do

Hello Team,my customer has a 400TB backend storage and 4TB ddb space (two partitions). Both ddb disks are full.I see 1.062.831.168 unique blocks on files db. Fact is he needs to increase his ddb space but it takes time to organize disks and install them. What can we do to bridge this time. Is there a “space reclamation” for the ddb disks too. May be a seal is the solution because from ddb view we start from scratch. I know the obvious consequences such as baseline and network load. Empty the ddb paths and do a restore was a thought. Do you have other suggestionsThanksJoerg

CV/Netapp A700 config permits only 36 concurrent sessions for backup copy jobs to a FAS8700: Is there a way to increase this ?

CV is configured with a cluster ndmp client and the nodes for the cluster are added in the ndmp client configuration. There are 6 physical nodes in the cluster. Source netapp is an a700 and the destination netapp is a FAS8700.Issue: For a backup copy job hundreds of jobs running but only a max of 36 transfer data. Hundreds of jobs trying to make a connection to the filer, but they can’t. These jobs are each grabbing a stream but only 36 at a time are moving data. Increasing streams helps but then more backup copy jobs that can run launch and consume streams.There is a snap primary, storagegrid backup copy, vault replica copy, and streaming data protection jobs that are very behind because of the supposed concurrent session limit (36 ?) from the source a700: streams keep being eaten up by backup copy jobs, but only 36 move data concurrently, thereby causing jobs for other copies to not run including the snap primary source copy for the storagegrid backup copy jobs.
