Hello Commvault Community, Is it possible to limit the number of sessions for virtualization backup (VMware) using a key or setting that will limit backup sessions per cluster, per host or per datastore within one large subclient? Such a need arose because in a scenario where a failure occurs on the hypervisor side and backups are launched from schedules, most/all jobs at once on development and production resources would fight for sessions (resources) at the same time, which will be problematic - limiting on the vCenter side may be inefficient. If it were possible to set something at the backupset or subclient level, it would also be good, because currently it is set so that practically every subclient is divided per cluster, which is inefficient at the moment and poorly manageable.Thanks in advance,Kamil

I have a user that has replaced a Linux client computer in Commvault with a new upgraded computer with the same name. I need to be able to restore backups from the original client to the new client but I can’t get the new client to show up in Commvault. When I try to bring it in I get the error “ Failed to get preimagemode xml file from client. Any ideas how to get past this error?

Hey Guys!If there’s no tool, i think it can be solved in the CommServe DB.I just want to switch a specific Agent, like File System/OES/Vmware to another client.Customer made some bad configuriations, and to fix it, i don’t want to reinstall/reconfigure all, which is a lot of work/time, and the biggest help for our problem would be an option to move (a double installed Agent/Client for the same Server, but can’t merge it because both have vm config. The old one has all the backup history, the new Client when reinstalled comes with a vmware client because customer created a new vm, but we need to attach the old backup history/configuration, to the new vm) an agent just to another client, which maybe can be just a little change in the CV DB. I’ve tried to google and search on documentation, but always get pointed to commcell migration, what is not our topic.Maybe you have some ideas for us, Thank you in advance!Kind regards,Jan

I’m trying to do a 1-Touch restore to a Dell R730. I have an iso generated via create_1tchbootcd.sh. I then attached the iso via the attach media feature of the idrac for the server. It boots and gets to grub just fine. Immediately after grub is hangs on this message.Trying to allocate 3315 pages for VMLINZ[Linux-EFI, setup=0x10b4, size 0xcf2878] Has anyone successfully booted a dell server via idrac virtual media with a 1-touch iso? Anyone know what might be going on here? The instructions say to use pxe but I’m trying to avoid that method.

Hello,Can you please tell me if there are any limitations regarding putting multiple DDBs from multiple storage pools on a single NTFS volume, other than performance impact?Should each DDB engine of each storage pool be configured to use separate folder? Or single folder for all DDBs should be used on single media agent?Thank you!Br,Andrejs

Hi dears, I have some inquiries regarding index server and webconsoles hardware refresh. I have an index server consists of 1 node Need to migrate it to a new hardware with recent OS version and wi add another node for the redundancy. What is the best approach?  follow the hardware refresh proccess for the index server then add the newer node - or add another node to the index server then perform loadbalance task to move the index data to the other node then remove the old node?  - or add 2 new nodes to the index servers then remove the old node which will run an auto scale task and move the data to the new nodes?Q2. I have 2 webconsole  with tomcat ssl cert applied on the servers , need to migrate the webconsoles to a newer hardware with recent OS.What is the best and easiest approach to perform this activity? This is a production email archiving environment.

Hi all,My manager wants to know the backup files list for a specific backup jobId via RESTful API through automation.At first, I thought it could be done using POST /QCommand, but I found out that data browse XML files cannot be run using POST /QCommand. To browse data, we need to use the POST Browse API.So I went to the POST Browse API documentation and used the following XML as a data payload for a Python script:<databrowse_BrowseRequest opType="Browse">    <entity _type_="0" appName="Windows File System" backupsetName="xxx_TEST" clientName="xx.xxx.xxx.xxx" subclientName="AUTO_xxx"/>    <mode mode="2"/>    <queries type="DATA">        <dataParam>            <paging pageSize="4294967295" skipNode="0"/>        </dataParam>    </queries>    <paths path="\"/>    <timeRange fromTime="0" toTime="1722328554"/></databrowse_BrowseRequest> I want to browse the backup task for all of its directories and files. The paths are under

In “normal Commvault Operations”, Should I have tapes in my tape library that have “Last Write Time” set as a date (not empty), and on them a write session (or a few), but the data on the tape is 0 bytes and no associated storage policy?For all storage policies/tape copies (except a few) we have “infinite” retention set on the tapes.  For those that do not, retention is “years” (except the DR tape(s) .  We do not re-use tapes.I have several (like 40 tapes) with “Last Write Time” set to a few days (or weeks… a few are months)  ago, etc and all are0 bytes. Not all tapes in the system that are 0 Bytes have Last Write Time set.  Using ‘tape → view contents” shows “no data” (as expected). The tapes show they have been mounted (“Number of mounts > 0) and there sems to be a file marker or 2 on them.So: I’m wondering how to tell “what its writing to them” and why or if “this is normal” as part of some internal 1 time “tape validation/initialization” job or something… but that doesn’t explai

Hello,In documentation (https://documentation.commvault.com/2023e/expert/configuring_worm_storage_lock_01.html) I see note: “Associating DDB backups and index backups to WORM copies is not recommended.”Could you please say why, and what are consequences if I will do so?Br,Andrejs

Hi, after upgrading from CV 11.28.100 to 11.32.56, my customer noticed that the JAVA GUI is suddenly trying to connect to: ipm.commvault.com. From a security perspective, they would like to know: Why is it trying to connect to that host? What data is being sent? Can this be disabled somehow? Any suggestions?Thanks in advance!

Hello,I want to setup secondary copy to cloud.Primary copy is using local disk library and DDB with single partition with path X:\DDBWhen I will create storage pool for cloud storage, should I create (or not) separate folder on disk X:\ for new pool DDB partition? For example X:\CloudDDBThere is recommendation from documentation that sounds strange for me: “When you create more than one storage pool using the same MediaAgent and DDB disk, make sure to specify the same DDB path. Do not create separate subfolders on the DDB disk for each storage pool.”https://documentation.commvault.com/11.24/expert/12411_deduplication_building_block_guide.htmlMaybe there is mistake? Two different DDBs pointing to same disk path?Thanks.

We just received an alert that the sku for autoscaling is being deprecated. Is there a new one we can use, and I assume an additional setting to define the new sku. I will attempt to use the windows sku, but I fear it may be next in line for deprecation. One or more image versions within the plan commvaultlinuxfr32 from the publisher, commvault, have been scheduled for deprecation. As of August 16, 2024, you have workloads that are running on these images. These workloads will continue to run and will not be impacted. However, additional instances cannot be deployed after the deprecation date.

Hi Everyone, We've got a customer intended to provide BaaS to its customers through Commvault. His main concerns are related to security. As his has customer which have their data located on-prem and which should be protected in the new BaaS. The concern is how the network design should be in order to transmit the data from the end customer DC to the new BaaS platform without exposing all the CommCell nodes to the internet. We heard of Network Gateways, but actually we do not have any clue how this can be done. If Network Gateways is actually the solution in order to only expose other nodes (CS and MAs), does that mean even the Management Plane (Access of the Tenant to the CommandCenter for Backup Management) is transmitted over the NetGw ? Any details regarding this would be nice, thanks in advance. Regards.

We want to have Azure Blob containers Immutable feature turned ON.Primary - Incremental - 30Days - AzureBlobContainer1Monthly Full backup Extended retention - 365Days - AzureBlobContainer1With Commvault Deduplication.Commvault DDB resides on the Media Agent.How so we handle DDB and the extended retention of INCR and Full on the Container1? Will the data on the container1 expire post INCR has reached its retention for 30Days? Currently we are not sealing our DDB. Do we need to seal the DDB when using Azure Immutable storage? Can we have one Azure Immutable blob and inside them have multiple folders with multiple retention? How does Commvault Retention linked with Azure blob Immutable - Access Policy - Retention Interval? What if Azure Retention Interval on AzureBlobcontainer1 is set for 30Days and My Commvault retention is for 365Days. what happens to the same data on 31st day?

Hi  all, we notice that at https://github.com/Commvault/terraform-provider-commvault, the latest update is a year old. I can’t imagine that this is finished and bug-free. Can somebody update me on the future of this project?Is it abandoned? Thanks!

Does Commvault provide a backup sizing tool (primary and secondary copies) which enables the calculation of the required storage capacity for the FET based on the required retention periods? 

Hi there,I backup a vm group on tape library for some technical reasons.For some backup jobs, data written on tape and Index information written on another tape.Can I include index information into backup data so I make sure that both be written on the same tape ?
