AuxCopy between 2 HPE StoreOnce Catalyst

We have 2 data centers, each having a HPE StoreOnce Catalyst Appliance and configured to a media agent in the data center.DC1- dc1mediaagent <> DC1 HPE StoreDC2-dc2mediaagent ↔ DC2 HPE StoreNow we want to get an AuxCopy going between DC1-HPE Store to DC2-HPE Store and another DC2-HPE store to DC1-HPE Store. We have tried configuring the libraries and sharing them to the other media agent.  but the AuxCopy fails with Chunk errors   Failures constantlyWe had no issues using Synology arrays between DC1 and DC2.Any ideas on best practice with HPE StoreOnce appliances? ThanksLarry

Reducing data retention (Aux copy)

Hi all, I start on this community, so thanks about all help you can give me. Near 2 years ago, we make a mis configuration on our infrastucture.Result : We have datas on Tape, which have bad data retention date.When I modify the retention date of jobs, I have 2 different behaviors :When I increase retention date : COMMVAULT show the right date When I reduce retention date : COMMVAULT don’t make any changesWhy ?How can I expect that datas expire at the right date ? My COMMServe is in 11.24.21 Thanks in advance

VSS DDB Backup Failures

Hey all - we are having a VSS failure for our DDB backups.  Providers look fine but seems like there is some sort of issue with it.Windows Application Log error says the provider could not be started.  The provider referenced is the Galaxy VSS Provider Service.  It is telling us there are no associated devices.This has been working just fine and then just randomly started failing on Nov 22nd.  Nothing has changed on the media agent.When running the vss creation manually - the error is VSS_E_UNEXPECTED_PROVIDER_ERRORCustomer will most likely open a ticket but wondering if anyone has any ideas?PS- we rebooted just for the heck of it...

Replacing Media Agent Hardware

Our Media Agent needs replacing.The replacement is probably going to be a Dell PowerEdge R5xx or R7xx with dual CPU and 128GB RAM and the intention is to use M.2/NVMe for the OS/Commvault binaries and DDB/Indexes but I’d appreciate any guidance and best practise on the build and storage.We’re doing a lot of synthetic fulls with small nightly incremental backups and we aux about 70TB to LTO8 tape every week.The disk library we have right now is approx 50TB.Is there any best practise that would favour NAS/network storage for the disk library over filling the PowerEdge with large SAS disks?With local disk on Windows Server is there a preference between NTFS and ReFS and is there a best practise over mount path size as we’re currently using 4-5TB mount paths carved out as separate Windows volumes on a single underlying hardware RAID virtual disk.Given modern hardware performance can anyone see a definite reason to do any more than buy a single PowerEdge for this other than redundancy/avail

Workflow: Cloud Upload and Download Throttling Control

I’ve used the subjected workflow some times and it’s working.However when I looked at it today it seems it was changed @ some point in time.The documentation isn’t corresponding to whats shown in the GUI.It seems that it’s not possible to target a specific cloud library any longer.Is it just on my installation this has changed, or anyone else seen this?Screenshots provided below.//Henke

Synthetic Full & Aux Copy Performance

I do several 10-20TB synthetic full jobs each week which are then aux copied off to tape on a global tape copy policy with a single stream (one LTO drive) with multiplexing enabled.I noticed that under the advanced settings on the synthetic full job the “Use Multiple Streams” option is NOT selected.What I think this means is that each 10-20TB synthetic full backup gets written to disk as a single stream which means it gets aux copied to tape as a single stream.If so am I right in thinking I want to enable this setting so the synthetic full jobs get written as multiple streams as this means they’ll get aux copied as multiple streams?I’m going to be moving the DDB to a new NVMe volume which seems a good time to review things.We’re on 11.20.73.Thanks in advance.

Low deduplication ratio on Oracle RAC DBs: why?

Hello everyone and thanks in advance for any hint.I’m running a Commvault V11Sp20 installation of the software and recently had a 6TB Oracle Database migrated from a stand-alone Oracle 12 DB to a three-node Oracle RAC 19 installation. Backups work properly and, “randomly” the three nodes are involved in backup jobs.Problem is: dedupe ratio is low.While the stand-alone data reached 95/97% of dedupe ratio, these backups for the Oracle RAC instances reach 40/65% of dedupe ratio. That is, a single Full backup takes something like 3TB of disk library (the very same disk library hosting the GDP previously used for storing the stand-alone Oracle DBs backups). Any hints about why the dedupe ratio is so low? Thanks in advance for your kind opinion. Regards

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?

Windows File System Backup & Archive Misconfiguration / Misunderstanding

When Commvault introduced the defaultArchiveSet alongside the defaultBackupSet I think I misunderstood how it was supposed to be used an this resulted in me misconfiguring that subclient. We have a file server which has a number of drives that I backup, but we also wanted to archive files within that backup location. So we setup seperate subclients one under defaultbackupset and one under defaultarchiveset. This has caused some of the same data to be backed up twice. What I am thinking is that we should have just configured archiving under the defaultbackupset subclient and left the defaultarchiveset alone?

Scality ARTESCA as S3 Compatible Backup Storage

Looking into CommVault supported S3 Compatible Storage Vendors I can see Scality RING but not Scality ARTESCA even though both are S3 Compatible storages.Would that mean Scality ARTESCA is not validated for use as Commvault S3 compatible backup target storage?

Implementing S3 combined tiers on AWS

Hey all We are creating a secondary copy and writing to a combined tier library.  When we create this, do we need 1 bucket or 2?  I only created 1 bucket and specified the combined tiers.  Does an additional bucket get created - or a different folder within the bucket created and that gets changed to Glacier?We are planning on using S3-IA/Glacier for the 2nd copy.I guess I just want more specifics on what exactly happens in this process. ThanksMelissa

I selected the copy precedence to be 1 (my primary copy)However, whenever the operation starts, it gives the error “Failed to read media during restore” and stops at 5%Everything seems fine. Until I tried to skip the errors, and I find out that the folders are restored, but no files in them.Please help out. Is there something in the settings I have to change?

DR backup to CV cloud

We are currently preforming a DR backups to On-Prem (multiple locations) and CV cloud. As viewed in cloud.commvault.com it appears that we are limited to only 5 iterations of the CV DBs. In “DR backup” options we have 20 set, but that seems to only be On-PremQuestion> Is there a way to expand the amount of CV cloud backups retained?

Backing up Exchange Databases from HD Library to tape

We had to back up some exchange Dags for short term retentions to an 3Par Disk library. The Mount Path is from one of our media agents where i can see what's stored on the 3Par. My boss wants me to back up the month of September that we have on disk to tape, so we can clear it out from the 3Par for another month of Storage.  Would the best way to back this up to tape would be to create a subclient on the media agent the drive is mounted to , target the Data Chuncks for the time of the month he wants backed up, and assign it a storage policy that will back it up to tape, or will that not capture the data we want from the 3Par?
