Storage and Deduplication

i would like to know how to restore a file deleted from a fileserverThanks.

Team, in the commcell in question the commservedr aux copy schedule seems to be system created and hidden. To that point, so is the data protection schedule for the primary copy. On the tape synchronous copy, there are extended retention rules for monthly and yearly. Those jobs picked for copy are to be retained infinitely and each need to be on their own tape, with no jobs from other months on the tape in question. Typically, the way to ensure this is to go into the schedule and select the options “start new media”, “mark media full on success”. Because the commservedr storage policy schedule for the aux copy seems to be a hidden system created schedule policy I can’t enable these options. How would I do this ? Is there a commcell level registry value to make the system created aux copy schedule for the commservedr policy visible (and hopefully editable)?thank you!

Hi, I need some info about the usage of HPE StoreOnce as a disk library. Something like this:https://documentation.commvault.com/11.24/expert/102869_add_hpe_catalyst_storage.htmlCurrently we're using one HPE StoreOnce catalyst store for a disk library. This gives us some single point of failure issue and we need to try and remediate this. So I would like to know what options there is. Like could we have a disk library with catalyst stores from multiple HPE StoreCnce boxes? Like a grid consisting of 4MA's with storage from 4 HPE StoreOnce. So in case there's some issue/maintenance we take down one HPE StoreOnce box at a time and backups will continue to run.

i can't use the  Disk Library Growth Trend report any more, he just show me the last day, although i set 7days ore any other time period.Unfortunately the link fore uninstall and download  a recent version from store is not working any more.https://community.commvault.com/storage-and-deduplication-49/showing-library-storage-use-over-time-1069has any one a idea how to fix or wehre i can download a new version? Moritz

  CV is configured with a cluster ndmp client and the nodes for the cluster are added in the ndmp client configuration. There are 6 physical nodes in the cluster. Source netapp is an a700 and the destination netapp is a FAS8700.Issue:   For a backup copy job hundreds of jobs running but only a max of 36 transfer data. Hundreds of jobs trying to make a connection to the filer, but they can’t.  These jobs are each grabbing a stream but only 36 at a time are moving data. Increasing streams helps but then more backup copy jobs that can run launch and consume streams.There is a snap primary, storagegrid backup copy, vault replica copy,  and streaming data protection jobs that are very behind because of the supposed concurrent session limit (36 ?) from the source a700: streams keep being eaten up by backup copy jobs, but only 36 move data concurrently, thereby causing jobs for other copies to not run including the snap primary source copy for the storagegrid backup copy jobs. Misc.From the c

Hello Team,Currently we are using LTO 7 HPE msl6480 tape library with 4 drives. Now we are planning to add expansion module with  LTO 9 drives. We will keep 2 LTO 7 drives for any restoration request and for Aux copy we will be using New LTO 9 drives. What changes I will have to make from commvault console end in order to meet my requirement.Note:- Our Primary copy goes to Disk Library and then to Tape(Aux copy).

Hi,I have a DDB that has high Q&I times. This is hosted on a an AWS EC2 instance with the disk type being “gp3” with 300 IOPS.Below is the Databases section. The Files portion of the DDB is not reporting the same issue. My concerns also includes the very high Pending Delete Records in it.  I can see that the Data Aging jobs do run as the Prunable Records does go down to zero.I attempted a manual space reclamation on this AWS S3 library that completes with errors.When looking through the logs it appears that the Media Agent does not have the required access on the bucket but the access does seem in place when using the Cloud Test too. Error on server.  Could this be contributing to the high Q&I values?Any ideas that could assist with this resolving this? Thanks.Ignes 

I have 2 lists of tapes in 2 libraries - let’s say 1000 tapes in each list - and they are all in scratch, and they need to be deleted from Commvault for physical destruction.Not all the tapes in scratch need to be deleted though. Only a sub-list of specific tapes.So what I need to do, is either select multiple tapes for deletion, or to import a list of tapes that can be deleted in one action.In the Java GUI, I can only see how to delete a tape one-by-one. That will take a loooong time.I have had a quick look in Command Center (I don;t use it much) and canot see a way to achieve this in there.Anyone have any ideas? Thanks

Hello Community!We have a customer who acquired 2 Dell DataDomains and were understanding that Commvault was interacting with the APIs on the DataDomains to launch auxiliary copies in “replication mode” so that the media agent would not be the data mover.After configuring the DD libraries and creating a secondary copy, the media agent is currently working as the data mover so this is not the expected behavior.Does anyone have any experience or information about how Commvault and the DataDomains interact for Aux copies?Thank you!

We noticed on a RHEL8.7 build with a local disklib & ransomware enabled that it breaks xfs utils.Opened a case with RH support. They said for mount options “try context=unconfined_u:object_r:user_home_dir_t:s0” instead of the recommended “context=system_u:object_r:cvstorage_t:s0”, which does fix the issue with xfs commands. Now they are asking me to ask you all do other customers have the same experience? Or, they suggested use the context that “allows xfs to work” to which I replied “I have no idea but this is what the script sets up”.Basically if you setup a diskib using xfs (not NFS or S3 obviously), simply try to run xfs_info or xfs_growfs, can’t be done. The workaround I found if I need to grow the FS is stop service, remount without ransomware context in place (or use their options), fiddle with xfs, then remount with proper context.  Looking for some way to fix rather than workaround but they seem firm in “it’s not a problem” with selinux or xfs, it’s the way it’s mounted.th

Good day,CS: V11.16.xBefore doing a hardware refresh for the CS, we created a VM in a lab with wins2019 and imported the CS DB during SP28 installation. all works fine. However, once login to the CommCell Console, we received a message indicating that the DDB was currently undergoing maintenance and required the completion of maintenance operations such as DDB resynchronization and conversion to a transactional DDB, among others.we have 2 DDBs, and the "convertddbTov5" plan indicates that there are 2 Memdb that need to be converted to version 5. Questions:  if the DDB resynchronization will function as expected after the CS hardware refresh, as two of the DDBs are MemDBs that will need to be converted to V5 after the successful hardware refresh and DDB resynchronization. Which logs will display the DDB resynchronization status and process, does "sidbengine.log"? if the DDB resynchronization or the "convertddbTov5" operation will impose any restrictions on the ability to browse or resto

We took on September 25th. The storage policy was set as below. Deduplication: Enabled Retention: set to 1 day and 0 cycles Worm Lock: DisabledOn the 26th, when the retention period had ended, CommVault sent in delete requests to the Cloud Storage for deletion of the metadata and indexes. However, no delete requests were sent for the archived data chunks. The Cloud Storage responded to these delete requests by deleting the metadata and indexes and responding to CommVault with a positive 204 response.MediaAgent CloudFileAccess log: 5916 1760 09/26 12:15:28 ### [CVMountd] RemoveFile() - deleteimmediatezerocycle/7Z8CZ4_09.25.2023_11.54/CV_MAGNETIC/V_3222/CHUNK_14571/CHUNK_META_DATA_145715916 1760 09/26 12:15:28 ### [CVMountd] RemoveFile() - deleteimmediatezerocycle/7Z8CZ4_09.25.2023_11.54/CV_MAGNETIC/V_3222/CHUNK_14571/CHUNK_META_DATA_14571.idx5916 1760 09/26 12:15:28 ### [CVMountd] RemoveFile() - deleteimmediatezerocycle/7Z8CZ4_09.25.2023_11.54/CV_MAGNETIC/V_3222/CHUNK_14575/CHUNK_

Hello   2nd Copies to Azure Cool Storage.In the context of architectural best practices for MediaAgent sizing (page #49), there's a statement that advises against enabling data verification for cloud storage libraries.https://documentation.commvault.com/2022e/expert/assets/pdf/public-cloud-architecture-guide-for-microsoft-azure11-25.pdfAs of October 2023, is this advice still considered a valid practice? Furthermore, what methods are suggested to avoid issues with corrupted data chunks in cloud storage? Does Commvault propose the practice of sealing the DDBevery 90 or 180 days for this purpose? thanks

Dear Team & Mike Struening, We are facing auxcopy completed with error issue last few months, We dont have Tape backup. We are facing below error:-  Please help us to resolve the issue.

Hello,just one question:If Commvault WORM copy with Dell Powerscale/Isilon Smartlock is enabled, will the data be pruned after the retention of the copy has met? Thank you.Regards,Thomas

Hi all,We have Pure as a primary storage. Using CommVault (via IntelliSnap) we backup data from it (Snap Copy). Then we mount snapshots to Media Agent (MA) and perform backup copy (Primary) from snapshots to our primary backup storage - which is NetApp (NA1). We have another similar NetApp in different location (NA2).Question - is it possible to create additional backup copy from Primary copy using SnapMirror\SnapVault?It is possible to create additional Snapshot Copy but you have to use NetApp as a primary storage. Which is not a case.So we want to have second backup copy (NA2) and it should be available as a source for restore for clients. And we don’t want to utilize our MAs and network when NetApps can do everything themselves.

Hi Everyone,Currently we are making traditional backups from HS to HS (Primary - Secondary Copy).We added an extra Cloud Library as AGC location as mentioned in the picture below.GoalThe AGC NEEDS to finish within 24 hours contains File System + SQL Agents that were backed up from the last 24 hours on the Disk Libraries.ObservationFrom the {Secondary to AGC} it seems that new bckjobs are not picked up after the aux copy started.Example: If bckjob 1-4 contains 10TB of data, commvault waits until these ones are finished and then will pick up the next bckjobs while some Media Agents in the Cloud Library are doing less work.ConclusionThe {Secondary to AGC} takes to much time (+/- 48 hours), after the Full Backups are finished in the weekends on the Disk Libraries. It does NOT meet the requirements.Questions1. Are my observations correct if yes, how to tune it?2. Any other options to meet the requirements? 

Hi together, I am planning a MediaAgent that has enough storage capacity to be my disk storage. Deduplication should be active, it is Back-end Size for Disk Storage Small (Up to 50TB).Are there any recommendations or requirements regarding the RPM of the backup disks? I did not find anything in the CommVault documentation, only the RPM recommendation for the OS/software disk.Thanks in advance for your help!

Hello,is there an easy way to find out copies in storage policies that are not scheduled? It is easy to find clients with “No schedule” but this option is not available for auxcopies.Thank you., Regards,Thomas 

Hi,I want to enable Horizontal Scaling but I don’t know how Commvault will handle old clients and subclients.Do I need to create new client/subclient?

I am trying to estimate the capacity I am going to need when changing the retention time on my Global Deduplication policy - Primary copy from 30 days to one year.If I look at the capacity of the storage policy now, w/ the 30-day retention period, would multiplying that by 12 give me an accurate estimate on capacity I will need to keep that primary copy for one year?  Ex - Primary copy w/30-day retention period = 300GB - changing to 365-day retention period = 3.6TB ? 

scenario: I have a WORM storage policy (deduplication enabled) of retention 3 days 1 cycleI have run 2 full backups to my storage on same day which completed 1 cycle of retention and with deduplication 7 days of retention is added so total (3+7) 10 days of retention. Will my first set of data be deleted on 11th day since it completes retention on both cycles and days or kindly correct if there is any gap in my understanding here ?

Hello is it possible to enable worm on a s3 bucket with infinite retention? If we want to worm only for 30 days with infinite retention what is the best way?Just create a copy with infinite retention and worm enabled on  it Create a copy of 30 days with worm and add extended retentionthanks in advance

Hello Commvault, we have been working with Commvault and Catalys HPE for 2 months since before we used Data Protector from Microfocus and Veeam. At first the performance was incredible but as the backups continued we noticed that the backup and restore speed dropped noticeably, reaching the point of restoring VMware VMs over SAN at a speed of 50GB/hour which is extremely slow. I reviewed the documentation provided by Commvault and also by HPE and the only strange thing I noticed is that the number of objects we had in the catalys stores when we used Data Protect or Veeam were from 2000 to 5000 and now with Commvault their stores store more of 40,000 objects and this does not affect the performance. I see that 30% are index objects that run at 1 pm. Please have any suggestions and if you have had a similar problem before.
