Virtualization and Containers

Good Day @everyone,quick question,we’re trying to move the s3dfsRootDir for Live Mount Operations to a dedicated drive.When Specifying the key: https://documentation.commvault.com/additionalsetting/details?name=s3dfsRootDiras an additional setting to the Mediaagent, we are not able to specify the location. If we put a value like D:\3dfscache into the key, the GUI displays, that the string is outside of the dictionary values. So I left the value “string”… But I am completely unsure where to define the actual location.Does someone struggle this behaviour?Best regards

Hello CommunityWe want to save a VM backup “Commvault Version 11.28.73 of a virt.Windows 11 VM under Nutanix AHV Version el7.nutanix.20220304.423, but unfortunately that doesn't work. A snapshot can not be set “Internal server error” and this error message appeared here:Description: Unable to create a virtual machine snapshot of [windows11-testvm]. [Internal Server Error.] Please check the virtual machine snapshot tree.Source: cvcs, Process: JobManager 

I could select one storage policy to do data verification, it will spend long time. I have more storage policy, any solution do data verification for yesterday backup job only?

Hi Community,In addition to the normal CV backup, I have the challenge of backing up the "virtual machine files" (*.vmdk, *.vmx, ...) on a stand-alone NAS, in an independent Commvault format.My idea was to restore existing backups via a dedicated proxy on which the NAS NFS shares are also mounted.Manually, via CommmandCenter, this works fine, but I would like to schedule it periodically with a monthly backup/restore procedure.Do any of you already have experience of how this could work?I would be happy about any answer ….

Hello everyone, I'm in a situation that's causing me some discomfort. I have 15 VMs located in one region and I need to replicate these VMs to another region, all within the Google Cloud environment.To do this, I'm using 1 MediaAgent to perform the backup and replication operations. However, I'm noticing that it takes a very long time to complete the entire replication process, taking around 15 hours to complete successfully. The first time running the Job, Commvault said that the Application Size was of 7.22TB. And in the last incremental, the Application Size it’s of 112.44GB. Because of this long time, I’d like some tips to help reduce this time, if there’s any documentation that can help. Thanks, 🙂.

Good morning,I’m trying to wrap my head around the following case:Let’s say there are two virtual machines, each with one 100 GB VMDK file (let’s ignore other files such as swap, etc. for the sake of this example). Each OS consumes 30 GB in total (Windows + Data).VM A - VMDK 100 GB, filled with 30 GB of data, thin provisioningVM B - VMDK 100 GB, filled with 30 GB of data, thick provisioningThe question is: will the full backup for VM A and VM B be of the same size (more or less) regardless the provisioning configured for each disk?The idea behind this question is to know whether thin provisioning speeds up the backup process and consumes less storage at the end of the day (especially considering that we’re running out of backup storage).Regards,

Hello Community, The domain controller is currently hosted in vCenter. Our plan involves replicating the domain controller from one site to another using Commvault VMware Live Sync.Questions :Is Commvault support this, and are there any considerations specific to DC live sync? Our primary concern around the trust relationship. If the source DC VM becomes unavailable and we need to power on the replica in the DR site without the latest replication, there's a potential risk of breaking the trust relationship? Are there any other critical aspects we should take into consideration in this scenario? thanks

Hello,We have a couple of servers which utilize RDM disks in VMWAre. These servers can’t have snapshots taken (as per errors in CV) because of these disks, even with disk filters applied.These servers are SQL servers, we need to protect the SQL data via the agent as per standard. We also need to protect the OS & D drive for ease of restoring these VMs. Based on the fact we can’t take snapshots, I need to protect the VM via the file server agent too.I attempted to install the file server agents over the SQL agents but it removed the SQL agent and put the file server agent in place instead.Is there a ways to leverage SQL & File Server agents at the same time?Thanks in advance

I am looking for a command wherein i can just give VM Name and delete that VM from Subclient which has many VMs in it. Is there a command or an XML using which this can be achieved. Need to use it for decommission process.

Hi Commvault community! Does anyone know if commvault has any paper for the case below?Does CommVault have implementation best practices documentation for backing up VMs on Oracle Cloud Infrastructure?Backup/restore performance involving Oracle Cloud Infrastructure is very slow. In the backup configurations of Oracle Cloud Infrastructure, there are no features like there are in VMware so that we can adjust and improve performance.Is there anything we can do on the CommVault side to improve performance?In VMware, we tested restores with a throughput of > 200GB/h. Oracle Cloud Infrastructure's throughput is always less than 40GB/h using the same servers.This makes an OCI native VM of only 50GB take more than 1 hour to restore. We don't have bottlenecks between Oracle Cloud Infrastructure and CommVault because the entire Commvault architecture is built inside Oracle Cloud.Do

Hello,Restore Guest files from the primary Netapp storage works perfectly but not from the secondary storage (snapvault destination).From the list of snapshots, the snapshot is failed to mount.On “Browse and Restore”, error is : Unrecognized error 30On primary Cluster Ontap, Datastores are on FCP LUN.On secondary Cluster Ontap, Primary LUN are replicated on volume.I suppose we have to configure the secondary Cluster, what do we have to do , LUN FCP, LUN ISCSI, NFS Volumes ? Where the snapshot is mounted on the destination, on MA, Esx or FREL ? Thanks in advance for your replies,Gilles

Hello,I observed, that using a schedule to initiate a syntheticFull, with run incremental backup before selected, against a Vmware virtualization subclient (vcenter - vmware - backupset - subclient) is failing.running syntheticFull only, triggers synFull backups for all protected VMs of that subclient.can someone explain the purpose of this additional setting: bEnableVSASnapSynthFull ?according to the documentation this is set to a default of: false.BRKlaus

While attempting a full VM restore, the restore is failing with below error. Unable to create the disks for virtual machine []. [Invalid configuration for device '0'.] 

Hello, I am considering deploying FREL’s from OVA to be configured as Access Nodes in a VMware Backup solution.https://documentation.commvault.com/2023e/essential/143780_deploying_vmware_file_recovery_enabler_for_linux.htmlIn the environment there will be a production network and a backup network.  Do FREL’s support the installation of a 2nd NIC to meet this requirement?  The FREL must be able to talk to the vCenter on the Production Network and transmit the Data to the MediaAgent on the backup network (achieved by using a DIP).  thanks in advance for any assistance!  

Hello guys, can you help me with a topic,I need to add a kvm environment to be backed up in commvault, currently there is already an ovm environment, but I don't know if I need to add more licenses, there are 17 virtual machines in that environment.

Hello everyone, We have an environment that consists of more than 100 VMs with a significant amount in TB in total. Analyzing the documentation https://documentation.commvault.com/2023e/expert/1661_hardware_specifications_for_virtual_server_agent.html, it only informs the sizing of the VSA and its capacity for FET.We have implemented 1 VSA with the Medium specification, however, when running some Jobs, we noticed that only 5 VMs at a time are executed and this is the number of Data Readers for VMs Groups for all hypervisors standard, as mentioned in the documentation: https://documentation.commvault.com/2023/essential/

Hi, We have setup a Commvault Media Agent to backup VMs using HotAdd transport mode.The setup works but its average throughput is less than ideal.The below is the setup of the Media AgentDirectly FC connected to a LTO-8 tape library with 4 FC drives 16 CPU cores 32 GB memory With the same above SPEC in our Netbackup environment, it can achieve an average throughput of 300MB/Sec, or 1TB/Hour. However, this Commvault Media Agent could only achieve around 500 GB/Hour, which is only half of what its potential should be. That being said, in Netbackup, we did increase its Number_Data_Buffers and Size_Data_Buffers to maximise its performance, so I’m wondering if there are similar parameters in Commvault that I can tweak to make it run faster ? Thanks,Kelvin

We run 11.20 CV. Need to restore a vm and it fails because we just recently updated vmware to vsphere 8.0 Will upgrade commvault to 11.32, but it will take some time untill we do. Meanwhile need to restore a vm and restore fails. What is the best workaround? Can we create a temporary older dummy host of older vmware version?

Hi,we use Commvault Simpana 11.20.36 and we have two Virtual Agents to backup our vSphere VMs.On the first enviroment the transport mode for VMWARE is set to auto.In the reports i can see that the transport mode for backup handles out SAN, the other enviroment only NBD.https://documentation.commvault.com/commvault/v11/article?p=32037.htmWhat can be the reason that the one environment does not save in san mode?Could it be a reason that in san zoning the esxi hosts of each cluster cannot see the media agent?RegardsDennis 

Hello All.  We have 4700 VMs with a couple dozen backups sets where I need to exclude VMs that don't require a backup.  e.g. AD, DNS, VDI, etc.  I know I can manually open each backupset and create a VM Filter, but I'm thinking there's a better way.It would be great to have a "global filter" for VMs similar to WinFS and LinuxFS clients.Is there a way to utilize PowerShell or CV CLI?Or is there some other way I’m not thinking and I’m making this harder than it needs to be?Thanks!DanPS after typing this I'm thinking I should have less backupsets…  but still interested in your thoughts.  :)

Hi, the customer has two locations. A and B. On both we have separate media agents with library attached. Media agents between locations don’t have any communication and we can’t change it.He was doing VSA VM1 backup on location A. They have migrated VM1 to location B and started backup. Full backup is working fine but during incremental we have problem with restoring indexes. During incremental backup the job tries to restore index from location A to the index cache on media agent B. As there is no communication between them we’ve got an error and the job failed. What can we do about it? Can we somehow recreate index on media agent B? Regards,Lukas 

Dear teamWe need a confirmation or explanation for the following restore issue. IntelliSnap Backups are running every 6 hrs.Only the last daily “full” is selected to be backup copied to a disk library.For NAS and Virtualization IntelliSnap backups, an incremental backup Job is interpreted as full.As  the result the last IntelliSnap Backup of the day is selected to be backup copied. Consultant did a Full VM restore from the copy available on the disk library but after the completed restore, the virtual machine did not come up. Since only every 4th backup is moved to disk library, he’d expect, that an incremental backup copy uses the last completed backup copy as reference point for the backup copy.But for him it looked as if the incremental backup copy is referencing the latest Snap Backup instead. Please confirm:Commvault needs the data of ALL incremental snap backups to enable a c

Hello Experts,I am trying to backup an instance in openstack on cinder volume. Getting below error Insufficient cinder quota for instance, Failed to meet minimum 10 percent available quota limit. Available: 8157 GB, Required: 30924 GB, In-Use: 301091 GB (out of 309248) As you see, my cinder volume is 300 TB of which current free is 8 TB. Commvault is trying to check 10% free space and fails. I know in vmware we can decrease the threshold check, I am unable to find this for openstack virtualization? I just need to backup a small instance (few GBs) hence if there is a way to reduce threshold for space check please share
