Storage and Deduplication

Hi All,is there some possibility to perform the action of “pick data for verification” for a job of a Storage Policy with a command line? Maybe I have to do it on a lot of jobs and I’m looking for a script.Any help is appreciatedThanks

i have a DR site with a vmware vsphere cluster. I use commvault replication to this DR site. I would like to monitor how much date is transferred after compression and dedupe.Where could i found this information ? I have a LAN to LAN 10Mb/s link and i want to understand what is transferred over the WAN.Regards

Hello, What is best practices Software Compression setting to reduces storage space? Automaticly its on SP but when are you suing compressie on Client and Media Agent? Or maybe turn compression off?

currently I backup S3 bucket with managed key, plan change the key to CMK, will commvault support S3 bucket backup with CMK?

1, Commvault support Data domain from 11.32,  it only support DD hardware, or also support DDVE(Data domain virtual edition)? 2, I write my primary copy to cloud library(Azure storage account), any chance to run AUX. copy to Data domain, want to see my secondary copy on DD

Hello,customer wants to use a storage system with native deduplication option for file services. Are there any known issues in backing up and restoring the system with NAS/NDMP? Or is it useful not to use the storage deduplication?Thanks and regards,Thomas

We would like to understand more upon how the data is uploaded :Multi-Part? Part size? Chunking? Average part count? Average part size?

Hi, We have a situation with filled up DDB drives in a 3-MA grid setup. XL-sized MAs but with 1.3TB DDB NVMe (should be 2TB according to sizing recommendations). The reson for the large DDBs seems to be due to a customer backing up a lot of small files that deduplicate quite well, we see between 25-30 billion secondary records and 2.7 billion unique records on the File DDB partitions. 94-95% dedup and performance is exceptional good with this amount of data in the Storage Pool, 60-70µs and ca 660TB. We also see pruning working as lowering retention also reduces the secondary records and give us GB back on the DDB volumes. We have two options in this hardware…We can expand the DDB volumes by concatenating (in Windows) another 1.3TB NVMe to the existing one, giving us 2.6TB on the DDB drives. Add one, two or three additional DDB-partitions (one per server) to the DDB, placing them on the extra, available 1.3TB NVMe (MAs in extended mode with 6 DDB partitions, each on a dedicated drive) A

Hello,We are using a shared commcell, but we need to send tape backup to a customer.We was thinking about restore a commserv DR backup on an other server, and then keep it on customer side in case of restore.But we don't know if we need a licence on the restored commserv and if we can run on both in same time.Or maybe you could know an other solution to ensure that tape backup can be used by customer without issue.

Hi, As I’m not really finding an answer in the documentation, I’m checking here if somebody knows.I would like to know if there exists a way to add exceptions to Selective Copies.Let’s say I wanted to copy all Monthly Backups to tape, except for example the first month of the year. I don’t see an “automated” way to do this. I could select the “Do not Automatically select jobs” and do it manually, but that kind of defeats the purpose. Is there any way to do this? Thanks

Hi Team, We have one requirement. We are planning to remove Old MA and Library and we are planning to configure New MA and  New Library.Is it possible to move all client data from Old configuration to new configuration?

Hi Support Team, We are running backups daily, weekly and monthly to disk library. Now we are going to take secondary copy in to tape with three tape drives.  So, The requirement is Weekly Full Backup for Database Servers and Monthly Backup for File server and application servers. Weekly backups need to take tape like First Week backup for week-1 Tape, Second Week backup for week-2 tape, Third week backup for week-3 tape, Fourth week backup for week-4 tape and Fifth week backup for week-5 Tape.Monthly backups need to take dedicated Monthly tape. Also Two tape drive for dedicated to backup and another one for restore purpose. Could you please help us how to achieve and its possible. Thanks Regards,ManiD  

Hi Team,We have enable dish cache for sql backup and log RPO is given 1 hour  and Commit is 4 hours. We can see the committed job but we can’t see log RPO jobs. I would like to know to check sql transaction log backups are backing up to disk cache.  

Hi Guys, We got a new SAN Storage, which is fully dedicated for backup. Since it's an FC Storage, we’ll present the LUNs to MediaAgents agents through SAN Switches. Our concern is about High Availability for MediaAgents regarding SAN. Is it possible to implement Gridstor through SAN ? We’ve already done that in the past with Object storage through mount path sharing. We now are wondering if this is feasible also through FC. Since SAN configuration implies Zoning configuration through SAN switches and LUNs are mounted locally into each MediaAgent. Overall, that's our need, being able to back up and restore through the SAN storage with 2 different MediaAgent and having some sort of HA in case of a failure of any MediaAgent. Any recommendations regarding this configuration would be appreciated. Kind regards.

DB2 backup size is 25TB, separate on 16 disks. I saw below article.Q1, any suggestion on maximum number of concurrent parallelism queries for my 25TB DB2 restore?You can improve restore operation performance by using parallelism.If the database contains a large number of table spaces and indexes, you can perform a restore operation more quickly when you set a maximum number of concurrent parallelism queries. This takes advantage of the available input/output bandwidth and processor power of the DB2 server.https://documentation.commvault.com/2023e/expert/using_parallelism_for_enhancing_db2_restore_performance_01.htmlQ2, any suggestion on the number of buffers and buffer size for 25TB DB2 restore?ou can improve the performance of restore operations of backup images by increasing the number of buffers.https://documentation.commvault.com/v11/expert/setting_db2_buffers_for_restore_01.html

I would like to know if there is a report on the historical growth of the Total Data on Disk Size attribute in a dedupe engineAny information provided is appreciated.  The total disk size as we know is the size of the reference jobs and data written

We are experiencing issues with our HyperScale cluster. The backups seem to be functioning, but we are receiving the following error message during backup:Error Code: [13:244]Description: [Deduplication failure] [Dedupe disk media] [Encountered a network error. Could not connect to the CVD on the target MediaAgent to launch the DDB engine.We also see this error message in the storage pool in Command CenterCreate Storage Pool Failed[Reason:There is an issue with HyperScale X storage configuration. The CV services are restarted on all nodes. Anyone know a solution? /Camilla

Hi,New to Commvault. We are trying to create a snap backup of an Oracle database to HPE3Par but this fails. ‘Strange(?)’ thing is that snap backups of the VM work fine. Do i need to configure something on the vmware/3par side?

Hi Commvaulters, Can someone advise me with the needed network ports to be open in order to perform an aux copy between 2 MAs.We installed a new MA on a remote site, and we want to open only the needed ports between it and the CS (For communication) and between it and the MAs located on the main site.Please to note that we are running CV version 11.24, I know that the main ports are 8400 for communication and 8403 for data transfer.Is there any other once that needs to be opened ? We want to minimize port opening in order to fully secure the remote MA. Regards.

Hello,is there a documentation of the needed permission to access Wasabi cloud storage? Customer does not want to assign admin permissions to the user. Thank you.

Hi, I can get this data after exporting a report to csv and manipulate it. Question is, how come there is no builtin report or dashboard or graph that would provide this in a simpler way? Regards,Pedro

HI Team. Environment has high powered media agents with all SSD that are proxy/access node/media agents. Using intellisnap. Need to configure vsa snap backup copy to use proxyless and mount the snap on the media agents and not using the esxihost. I’ve found a lot of documentation talking about it benefits and caveats but nothing that states how to actually configure it. VSA subclient forces the configure of (just 1) esxi host to act as the proxy to mount snapshots. Thank you.   

Dear Community, Thank you to everyone in advance for their replies - we have a bit of a headscratcher on our hands here, one that we have failed to resolve despite our best efforts so far. A support case is ongoing, but we were pointed back towards our own infrastructure - but let's start at the beginning. September 8th, my former colleague and Commvault admin (who unfortunately left the company) enabled storage policy level encryption. This led to some issues where synthetic full backup jobs were no longer running due to decryption issues, which in turn led to our primary media agent running full.September 25th, I once again disabled storage policy encryption because I thought that may fix the issue, but it did not. I created a spillover path on our offsite media agent to keep backup jobs running, and a few days later, the issue that caused the synthetic full jobs to fail was resolved. Some data was written to the mount path (associated with the same library, but mounted on the offsit

I write backups to an on-prem SAN.  I have a small amount of data on one client that needs to be encrypted to meet a data at rest encryption requirment.Is there a way to only encrypt data backed up from a singe directory on a Windows client?  Or a single drive on that client?If not, what is the best option for encrypting my data at rest with the least impact on backup times.  I do not need to encrypt it in transit, just at rest. Thanks,Larry Upton
