HPE StoreOnce disk libraries and Command Center

I’m new to CV and still trying to sort out Commcell Console versus Command Center, so I appreciate your patience. After 4 years with Veeam and two decades with Data Protector, Commvault is proving to be quite a different animal.My first concern is why it takes googling some arcane code (ActivateHPECatalyst) to enter in the Commcell Console properties to make visible the StoreOnce option for library creation in the UI. What is the rationale for hiding the StoreOnce option in the first place?Now that I’ve added a Catalyst-backed disk library in Storage Resources > Libraries via Commcell Console, I go back over to Command Center, look at Storage > Disk, and I do not see my new disk library. How then am I supposed to add it to anything as a backup destination?

How to show if my backups are encrypted

The auditors want to see if my backups are encrypted and I’m not sure where to go in the CommVault GUI to show that. I don’t see anything about encryption in the properties for my storage libraries or my storage policies. Where do I show whether or not my backups are encrypted?Ken

Moving the DDB for a cloud storage libray to different on-premises MA

I have several cloud libraries, where the storage and DDB are controlled by an on-premises MA. I would like to switch several of them to a different on-premises MA. But cannot seem to find anything here on it the docs on how to switch MAs for an existing cloud library.

Storage policy jobs preference

Hi,in our case there is a lot of running jobs accros multiple storage policies. Once the jobs reach more than 90% of completion, the throughput of the job falls and the speed of the job is very slow. However,some of the jobs, that have less than 50% in progress status, are running faster.Is there any option to prioritize jobs, that are almost finished (with more then 95% of progress)?I know there is possible to change priority of the single job, however, from my experiance it didnt increase speed too much. Maybe I should have used the highest priority, that I exactly dont know.

DR of scale up Media agent

Hello, IHAC who has a NetApp eseries as their disk library. When MA1 writing to a lun fails, the lun needs to be mounted on another MA2 to restore the backups. What is a standard procedure in Commvault that could be used to open the same mount path from a different media agent. From the Commcell GUI one can only create a new mount path. The goal is to be able to restore the data protected to this LUN from a different MA.

System Created DDB Verification schedule policy - use of streams

Hi there, is it safe to limit the number of streams to be used in parallel for System Created DDB Verification schedule policy? I am asking because in our case this verification policy consumes 30 streams out of 30 streams. However, there is set up use maximum number of streams, why is 30 limit then?Secondly, I would like to discuss Data Verification Options. Which option do you use preferably? Would it be enough to use only Verification of Deduplication Database instead of Verification of existing jobs on disk and deduplication database?

How is backup encryption handled ?

Hi guys,I’m struggeling with encryption in a mixed environment.On the GlobalDedupePolicyCopy, I did not activate encryption.on the Client Advanced Property I enable encryptionon the subClient Property I enable encryption on Network & Media.executed Jobs are listed as ecryption enabled.does this mean, that the backups have been encrypted ? are the backups deduplicated against unencrypted backups within the same StoragePolicy ? (which might result in a mix of encrypted and unencrypted data for the same job) Since encryption is defined in the GDP and I already have two DDB partitions per MediaAgent, do I have to deploy additional MediaAgents to host the dedicated encryption backups, in case I want to enable that on the Storage Policy ?best regardsKlaus

Best Way to Confirm Combined Storage Tiers Functioning

What’s the easiest way to confirm a Cool/Archive cloud library is working? I have migrated data from a Hot storage blob container. I provisioned an additional storage container as Hot in Azure and provisioned it as Cool/Archive as recommended by Commvault. I attempted a restore of a file from this Archive library and the restore just completed as normal without the use of a workflow so I’m worried the data isn’t in the Archive tier as expected. Any ideas how to confirm the data is actually in Archive and Metadata is in Cool? And why was the restore just standard?

Aux Copy with various tapes

Hi.I have a lot of jobs to copy to tapes.I´m doing it but it is taking too much time, because each copy is using one tape. There are copies with a lot of images, and I have 6 drives to use. I want to use more than one drive at same time to copy this images.Any idea?Thanks.

Reservation Status: No new readers can be allocated

Hello, in the log of aux copy job (primary copy(disk storage) to secondary copy (tape library), there is this information: "Reservation Status: No new readers can be allocated, check for additional streams after [900] seconds, pending streams [1]". Can you explain here, what does it mean and possibly how to avoid this? Can this state caused slow backup performance?

Drive allocation policy discrepancy

Hi all,in Master Drive Pool Properties there is set Drive Allocation Policy to Use All Drives. In our case, we have 4 drives fully accessible. However, only 2 drives are in use. Is it possible that this settings is somehow and somewhere overriden? Is there way to figure out why are some of the drives idle? There is a lot of running jobs accros the multiple storage policies so it would be good to utilize all drives.

Auxiliary copy is stuck at 30%

Our weekly secondary AuxCopy is stuck at 30% since this weekend (so that it is blocking all the primary disk to disk incremental copies), with the below 2 error messages Thinking it might be some ports communication issue between the Media Server (S01190) where the tape library is attached to, and the CommCell Server (S02116), so I did the below ports check between the 2 Servers: Telnet from the Media Server (S01190) to the CommCell Server (S02116)Port 8400 OKPort 8401 OKPort 8403 OK Telnet from the CommCell Server (S02116) to the Media Server (S01190)Port 8400 OKPort 8401 Not OKPort 8403 Not OK Now, before I speak to our Network/Security administrator who have recently installed SentinelOne AV on both of the above 2 Servers, I’m wondering if I’m heading the right direction, and if I have done all the ports checking ? Thanks,Kelvin

Possible to increase the Aux Copy anomaly threshold?

I do full backups of production servers on Friday night and non-production servers Saturday night. Every Monday my inbox has roughly 20 anomaly emails about aux copy jobs running longer than usual. This has been going on for months now. Is it possible to tweak the anomaly thresholds in CommVault so I get fewer emails?Ken

Critical Event - DDB reaching QI time threshold...

Still a noice commvault user.. Noticed that we have been getting the following Event in the evvent viewer.. DDB(s) reaching QI time threshold for adding new Subclients [{DDB [XXXXXX-GlobalDedup_Databases_5] MediaAgent [XXXX-cv1a] Path [D:\XXXX-DDP] AvgQITime [1153] Free Space Percentage [94] }]. New DDB(s) may gets created if it crosses threshold. Please review the DDB configuration, for more details refer Deduplication Building Block Guide on Books Online. Can anybody help me understand this and how to correct this. Our small environment is all on AWS. Thanks BC

Showing library storage use over time

Hello everyone,At my DR site I use HP MSA disk devices for CommVault backup storage and they are currently over 86% full. I have asked my manager to add the cost of another MSA to the budget and she’s asking for growth rates to ensure that one MSA will be sufficient. I’m searching for that information and am not able to find it even though (I would have thought) that this is a pretty basic information. I did find the “Disk Library Growth Trend” report but don’t trust its numbers as the used space and free space increase at the same time despite the fact that the total storage has remained constant. I’m not sure where it’s getting its information but, well, it just doesn’t make sense. Screen capture below.So my question is: How can I find a storage growth rate to use for media agent capacity planning?Ken

Does anyone have a write-up on DDB Version 5?

Hi!Commvault FR 11.20. We’ll be upgrading to FR 11.24 in the Fall. We’ll also be standing up new Media Agents, with new DDBs. Is anyone aware of a write-up on DDB Version 5? All I can find are references to upgrading from DDB Version 4 to Version 5 (though it doesn’t tell you how to identify what version you’re currently using). https://documentation.commvault.com/11.24/expert/134342_upgrading_deduplication_database_to_v5.htmlI also can’t find any references in it in the release notes, though I think it first shows up in FR11.20. It appears to be far more scalable than previous versions. I just want to read an explanation of how it works. Thanks!

Inline Copy caveats

Hi all,please make me the topic of inline copy clear. I understand, that if primary copy fails, secondary copy (aux copy) fails as well. However, if for some reason the storage for the secondary copy was not accessible and secondary copy was not able to carry on, what would be with the primary copy?

Synchronous Copy to Selective Copy

Hi there, I have a synchronous copy to tape (aux copy job is scheduled every day). Now, I want only one weekly full backup to be copied to tapes. Is there only way to create new selective copy to achieve that?Am I right, that only changing schedule for synchronous copy from every day to every week can not help - in that case all jobs from the previous week would be copied once a week at a given time ?
