about Api

Hi, I am dealing with api’s for a project, so I need to see backup job’s that’s why I use this api “http://WebConsoleHostName/webconsole/api/Job” and this api  returns all the jobs in the past one year in CommCell environment. But some jobs are missing, I can not see, How can I see all the jobs ?

Writing new blocks after large volumes were cutover to a new server

Hi Commvault people,I am looking for some advice on a recent volume migration, and Commvault’s behaviour afterwards.So we basically upgraded a large fileserver. 60 TB of data across several volumes.The data on “Server 1” is already under dedupe.When we migrated the volumes to a “Server 2”, although we are obviously creating new subclients, and we have to kick-off new fulls, I was surprised to see these new backups writing large amounts of data.Previously, we were writing minimal amounts of data, literally a few GB’s, despite the volumes being around 15TB (very small rate of change).Given that dedupe is in play, and we already have the blocks of data held in the store, then why are we writing so many new blocks? To put this in context, we are writing maybe 30% of the application size, which is a few TB’s, compared to the previous few GB’s.Hopefully that makes sense. Basically, i am trying to work out why Commvault is not using pre-existing blocks for these new backups.Thanks

Proxyless backup copy without an esxi host - how to configure

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.

OnePass retention settings and backup chain

For Archived data produced by the OnePass feature in Commvault what determines the retention time in the Storage Policy Copy?There is a “Basic Retention Rule for All Backups” and a Basic Retention Rules for Data / Compliance Archiver Data. If I’m right the Basic Retention for All Backups setting would dictate retention for “backups” that were referenced by subclients to that storage policy and the latter would just reference data that was archived by OnePass and uses the same storage policy copy? So if the “Basic Retention Rules for Data / Compliance Archiver Data” setting is infinite data created by OnePass will never age out? Secondly if the schedule associated with OnePass is configured to do a nightly incremental and never a Full or Synth Full what is the impact of deleting a heap of Incremental Backups in the backup chain? A full was done only the first night this was set up.I was never intended to retain the Archived files indefinitely and as a result 3 years of unwanted non dedu

Network Throttling for Aux Copies

Hello, We have multiple sites and all these sites have different WAN bandwidths. All are DASH copying to  a single location. All these locations have different working hours. We want to create multiple bandwidth throttling rules. What would be the best way to approach this? Should we create the rules at the source Media Agent with throttling the send traffic? Thank You

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!

New DDB(s) may gets created if it crosses threshold.

The SDT data transfer was terminated on a request from the Job Manager on 11.20.40

Running v11SP20.40.  We’re having a ton of occurrences in the last 3 weeks of this error across multiple environments:[The SDT data transfer was terminated on a request from the Job Manager.]I work in a MSP environment with the CS in one datacenter and the MAs spread out around the country.  We have a minimum of 10GB on our datacenter links from MA-MA and MA-CS.  I’m curious if anyone has seen this and has any resolution or troubleshooting steps.Thanks!

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.

Remove DDB with no associated jobs

Hi, I’ve an old sealed DDB with no more jobs associated to it, it only shows some number of unique blocks left ( for a size of 1,18TB ) , secondary blocks is 0 ,  application size is already at 0. How can I then do what you proposed to do: “then remove ALL of the blocks for that store in one big macro prune.”?Cause I’d like to get totally rid of that sealed DDB ?

Immutable Backup Images

We currently have a ‘dual-site’ scenario - each with 2 media agents attached to a Dell/EMC ME4084 disk library.  Commvault is configured with a CommCell in each site - with failover enabled.  Backup images are secured in each local site and then a secondary copy replicated to the alternate site.As I am sure is common - the questions are being raised around immutable backups in this CV environmentI have seen documentation regarding immutability of cloud based backups, and discussions of WORM technology - but am unsure as to what applies to us here with our CommVault / disk library configuration.V11 SP20Any input appreciated…..

Badly marked LTO8 tapes

Hi all, We have a following issue. The LTO8 tapes were badly marked with LTO6 barcodes. Then, the tapes have been remarked with right barcode. However, Commvault can not recognise the newly remarked tapes - Commvault says that the barcodes had been already used and tapes were moved to retired group. We tried to perform Discover,  Full Scan (inventory) and Update barcode for the given tape without success. Is there any workaround for the issue? Is there only one way to somehow fix the tapes within the tape library?

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

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.

Cloud storage adding and troubleshooting

Hi there,I am trying to add a new cloud storage (S3 compatible), however I am unable to do so. Moreover, I don’t see any asociated log files. I only see this error message:“Failed to verify the device from MediaAgent [xxxxxx] with the error [Failed to check cloud server status, error = [[Cloud] The server failed to do the verification. Error = 44037]]. “ My question is: Which logs should I add to Logging setting? And how to troubleshoot this stuff in general? PS. As workaround I used this - https://documentation.commvault.com/commvault/v11/article?p=51230.htm but it didn’t help. Thanks for any ideas

VAST Universal Storage

Has anyone kicked the proverbial tires on this yet either from a NAS or S3 target? Curious to know if CV is qualifying it internally or if it’s on anyone’s todo list.

Unexpectedly sending data to storage meant for once per year backups

Hello everyone,I have a question about storage policy configuration.  I take incremental backups every day but Friday when I run a full backup.  Retention is:Incrementals: 2 weeks Full backups: 30 days Monthly fulls: 1 year Yearly fulls: 3 yearsI have a primary and secondary site but the secondary site has a much smaller media agent and I actually ran out of space.  To address this, I added CommVault Metallic cloud storage with the intent that the once per year Yearly Full backups would go to the cloud.  Just today I noticed that 10TB of data is being replicated to the Metallic Cloud storage and I can’t explain why.  Can you look at these pictures of my configuration and explain where I went wrong?Ken

is it possible that I restrict commvault to use media from designated slots (not to scan/use all library slots)

I am running a migration from other vendor to CV.    For a time being, is it possible that I restrict commvault to use media from designated slots (not to scan/use all library slots). Just to avoid conflict as the tape library would be having CV as well as other vendor media.

Enabling Ransomware Protection on a MediaAgent for disk library

Hi Community , Does Enabling Ransomware Protection on a windows MediaAgent CV feature make my disk library and backup copies immutable ? Do we also need WORM enabled primary or secondary copies even after enabling this CV native feature for full proof ransomware protection ? If yes , what is the use of ransomware protection feature ?Regards, Mohit
