Storage and Deduplication

We had an FM200 release in our data center.  DDBs became corrupt and restore failed.  Sealed and started new DDB to get backups running.  Now all jobs have aged out of the sealed DDB, but I still have 387TB of data on disk and I need the space back ASAP.  SIDBPHysicalDeletes not showing continuous activity.  Data aging ran multiple times.

Hi Everyone, We Currently have Commvault commserv (All VMware Environment) targeted to HyperScale appliances. However, HyperScale 1300 is EOL/EOS. We have a spare HP MSA 2050 SAN storage available and require your advise before we configure it as a library.As HP MSA being an entry level storage, is it recommended to be used as target library even though disk speed are 7k for  HyperScale and HP MSA? Would there be performance issues as storage needs to mounted to additional server server to be used over 10 gig network as VMware does not have SFPs? Would configuring backups on HP-MSA give us same dedeuplcation ratio as that of HyperScale appliances ?

Hi Community,We have Data Domains as our primary storage for Commvault and tape for long term retention. We are looking to replace the tape libraries within the next year with DD Cloud Tier. With DDBoost now fully supported as access and client libraries does anyone know if and when DD Cloud Tier may be integrated and supported.

If you enable horizontal scaling for a DDB.  This is straight-forward for primary copy.  Once it reaches a certain threshold it will scale to a new DDBand new subclients will use the new DDB.  Now for aux copy/secondary synchronous copy ( we dont have subclients to associate here ), how does it work? What happens to the previous DDB and to the newly scaled DDB? Does aux copy continue on the new DDB automatically and leave the old DDB for copied jobs already? Anyone who can explain in simplistic term?

Hello All, For the past 2 weeks, we have been experiencing the following issues.All IntelliSnap operations are extremely slow.This affects VMware, Volume Snapshot and Exchange.We use IntelliSnap for this and have NetApp storage behind it. Globally, the behavior is the same everywhere. Locations with OnTap 9.15 and also OnTap 9.11. Not only individual locations are affected, but all of them.Even sites with their own physical media agents.In other words, the error occurs everywhere. We have tried everything. The Commserv is not overloaded. It has 4 socks and 16 cores.128GB RAM. The SQL database is also not busy or extremely overloaded.What steps did I take:- Moved Commserv to another VMware cluster.- DB Maintenance- Installed SQL and Windows updates.Started a job, same phenomenon.Our network team has carried out all kinds of performance tests. No abnormalities.Commserv and media agents are in the same VLAN.The support team has opened 2 cases and filed them under VMware and File Snapshot.

We have some trouble with paths to a Synology nas going offline.Currently we have the DNS name in the path. I’d like to change that to referring the IP address instead. I’m pretty sure I can do it without any issues but better safe then sorry. Anyone see any risks of changing the \\DNSname to \\IPaddress for the path(s)? //Henke 

I am currently using cloud storage libraries configured with AWS IAM accounts. Our organization uses Azure for SSO to AWS.Is it possible to reconfigure the cloud libraries to use Azure credentials?

Hi,I’ve needed to delete - create again the DDB and I need to use same partition paths as they were used before (disk was formatted). Currently I cannot create a DDB as I have message: “The specified mount path os already in use”Well I know that it’s described here:http://kb.commvault.com/DD0051 But do you know somebody if there is way to force cleanup and do not wait 24h ? The data aging is not doing the trick. Thanks

Error restoring DDB Store files. Restore job(s) [] encountered one or more errors.2 please help help ugent…..

Hi All.I have a setup with DD9400 which is my production library and I have replication to Vault which is DD9900. We are trying to restore the data which is from the vault in the production site. I have created one mtree/storage and made it as library, I have created one more mtree/storage and made it as my vault replication. I want to restore the data which is getting replicated from vault to prod. Is it possible to do this task in Commvault. RegardsVijay

Hi,We have a deduplication Database that it doesn’t seem to deduplicate at all and is ocupying more than we guess it should be.that DDB only backups VMs ans the deduplication ratings showed in the DDB are horrible and it caused that the library is full.   Best regards.

Hi Community,I had recently moved a mountpoint to and existing drive. The move mountpoint job had completed successfully, but the data from the old mountpoint has not been purged. The size is approx. 12TB.What can I do to purge the old data, as there is another requirement for the provided LUN.  

Scenario:Local on prem copy - 60 day retentionAux copy to Azure - Long term retentionWe would like to set compliance and worm lock on the Azure copy. Questions:In prior feature releases, the suggestion we were given was to have multiple libraries/storage pools that would be rotated half way through the worm lock. Example: A 30 day retention/ 60 day worm lock, at day 31 you switch jobs to a different worm library for 30 days, rinse repeat. Is this still the case? Our Azure retention is up to 7 years. Would the best option be to have the first Aux land in a hot storage bucket that’s immutable for 30 days, and a 2nd aux written to a non immutable storage account utilizing DDB for the full retention period? 

How can I confirm how many blocks a DDB data verification job processed after it is finished?We have a scheduled policy to check data consistency with the following options. It seems to me that the job is processing all single blocks.    

Hi Team,Im wondering if anyone has any success, or otherwise using S3 standard as a Primary copy.We will be deduplicating.That would not be my preferred option, as I always prefer faster disk than a Cloud-library offering, but the question is being asked.We do have some fairly large databases (a few TB’s) and I’m wondering how the throughput of say a 5TB DB would hold up in a restore situation.It would be good to hear people’s feedback on this subject.Thanks

Dear Commvault Experts, My MS SQL AG cluster has a primary replica, as well as a secondary replica,I have create a Commvault client for backup in Commcell, I am curious that,  which AG’s replica will be used as a source that is being accessed by Commvault backup feature?Is it primary replica or secondary replica of AG? Appreciate any help or suggestion!Thanks

Hi guys, We are implementing an Air Gapped DR site, so the DR site only receives an offline copy from the main one through aux copies.For aux copies, we only disabled their schedule from the “System Created Autocopy Schedule” and created a new specific schedule which start the aux copies to the DR site after the blackout window. Since the DR MAs and Library are only accessible during the Air Gap window, I was wondering if rescheduling the remaining system created jobs (DDB Backup, DDB Verification, DDB Space Reclamation, Data Aging) to the Air Gap period doesn’t cause any issue when running at the same time with the Aux Copies (Our Aux Copies use Deduplication). I know that, when running the DDB Backup jobs, this may cause issues with Aux Copies as of the screenshot below : https://documentation.commvault.com/11.24/expert/12504_deduplication_database_backup.html So my question is, is it possible to launch all the previously listed system jobs at the same time with Aux Copies without an

Hello Team, please help me with a suggestion on my Auxillary copy job running very slow.  

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

Hello,I have a doubt in setting up DDB Creation in awindows cluster environment.2 physical servers with installed media agent and a virtual storage (starwind)1) can the DDB be on the storage shared by the nodes of the cluster?2) Can I use only 1 DDB for all nodes (MA) or should I have a DDB for each MA? 

Doing some preparation of our DR environment and wondering, if we intend to only do restores in the DR environment, is SSD still a requirement? My thoughts were the performance is required to do signature lookups (for writes), but for restores this would not be required. Thanks!

I have created a disk library in our dev environment which is using it’s own separate volume. it will be used for ddb backups. If I want to increase the capacity do I have to add a new volume or can I just resize the underlying volume in linux ?  

Hello All,I would like to use the Amazon KMS for the encryption, how do I achieve this. Do I need to register the Amazon KMS in our commcell and use it in our policies?As per below documentation we were asked to add additional keys to enable encryption. How that works, can anyone explain.https://documentation.commvault.com/11.24/expert/9263_enabling_server_side_encryption_with_amazon_s3_managed_keys_sse_s3.htmlwhat is the difference between the above documentation and registering the Amazon KMS in commcell?
