RHEV access node requirements

It looks Commvault still only support RedHat 8.7 for access nodes in RHEV environment, this is a pretty old OS. Is there any time line when they want support 8.10 or 9.x for access nodes?

Force Full (or SFull) backup of VMware VM after SP/Plan change

Hi, I have a scenario where I will need to protect VMware VMs which can be located either on Datastores from Storage1 device or Storage2 device. I will have 2 plans setup for this: Plan1 will backup VMs from Storage1 datastores to a backup Pool2 Plan2 will backup VMs from Storage2 datastores to a backup Pool1 The issue is that Pool1 is tied with Storage1 and Pool2 is tied with Storage2 in the sense that if Storage1 goes down for any reason then Pool1 will be unavailable too. The same is true for Storage2 and Pool2. The other issue is that VMs can migrate between Storage1 and Storage2 For these reasons I always need to have last backup chain available on the pool that is independent of the Storage device where VM is sitting during backup. Some time ago it was a default behavior to force Full backup after changing target Storage Policy and since my Plans use different Pools/SPs, then and that would basically solve this for me. But this is not the case anymore. So my question is: is there

Config post VM Migration

Hi All, When a VM migrates from one vCenter to another Commvault creates a new backup set name for example original set name is defaultBackupSet but after migration under the VM client you get a new Backupset called defaultBackupSet_ vCenterName and a new default subclient, We’ve been disabing the subclient in the original Backupset but what is best practice for dealing with the old Backup DataSet and subclient. I hope the question makes sense,

VSA Job Results folder usage behavior sizing

Customer is on 11.32 and is having a problem with Job Results folder filling up on backups. They’re VMware Primary backup is done in the field to a local MA/access node. Backup is VM backups, mounting snapshot, backup, release snap, auxcopy later. VM in question is 8.5TB and erroring out over the weekend when no restores are being done. Synth full Saturday, Incr Sunday… error out with filled up Job Results. They’ve filled the job results folder up twice now, once at 100GB and now at 300GB, and don’t want to keep chasing this issue. Customer would like to know behavior of the job results folder usage in order to properly size remote locations for backups. When does it release space? Question for Job Results (it keeps filling up even at 300GB) - do we need space for: a. files (as explained with a massively complex formula) and VM space (2% of VM size) b. just VM space And then how can we minimize the space requirements? Thanks. Steve F

Re-install Windows client on commvault for backups

Good day i hope you are welli am struggling in terms of re-adding windows file system backups on commserv.the steps i took is re-installing the content store on a rebuilt server and setting up the configs for file server and point to commserv gateway. when running the final install to register, it said that it will register ;later with the gateway server due to the fact that it is in maintenance mode. i also did create the windows client on Comserv under client computers and when clicking on reconfigure, i dont think it linked properly with the content store from the rebuilt server. please help

Guest File Restore Only Showing C Drive

I seem to have multiple servers that only show the C drive when doing a guest file restore. If I mount a whole disk I can see all the others. I have other servers in the same backup Plan that work fine, have very similar servers that work fine, I can’t tell why it isn’t showing. Anyone had this? I’ve logged a ticket but not much of a response so far

Test failover for Auto-Recovery for VM - Live Mount only?

Hello I need to provide an isolated/test environment (with IP masquerading etc.) to perform set-of-VMs restores on regular basis (like Veeam SureBackup) For Command Center I can use Auto-Recovery feature with “Test Failover” option but as far as I can see we can only use Live Mount (https://documentation.commvault.com/11.38/essential/testing_failover_for_periodic_replication_group.html) How to perform such isolated & automated test with regular streaming restores instead of Live Mounts? Production/source VMs should remain online and untouched during the test. I am aware that I can achieve something like this with old-fashioned Virtual Lab managed by deprecated CommCell Console https://documentation.commvault.com/11.38/expert/creating_restore_as_lab_policy_for_vmware.html, but I want to follow brand new Command Center ;) Any thoughts or findings will be appreciated. Kind regards, eMF

ova deploy via Command Center. Choose another VSA access node than primary

FR 11.32 A FREL.ova needs to be deployed via CommandCenter. documentation: Configuring Deployment of the VMware Image in an Offline CommCell Environment Save the Access Node and MediaAgent (FREL) OVA file directly on your primary access node as defined on the Hypervisor client within its configuration tab. Does a possibility exist e.g. a key that I can deploy from another access node than the primary? I know the several other methods to deploy and we cuurently try to change the primary access node but this is not the goal. Thanks in advance Joerg

splay synthetic fulls over more days

Hi all, This question relates to v2 indexed VM backups. I’m running out of ideas and wondering what special reg keys might exist to somehow force the “auto” synth full schedules over more days than the rolling schedule based on retention). In this case we backup 3000+ VMs, most of which use a single plan but multiple VM groups/subclients to split them up by datastore. This used to work OK before moving to plans as each subclient would or could have its own schedule policy. My question is what do you guys recommend to split the synth fulls up ideally accross 7 (or 14) days given that is the retention? Basically becuase of how things were discovered, migrated, etc., there are days of the week where 1000 or more synth fulls run and many days where none run, so, that’s the issue trying to solve. I thought about derivative plans but I’d still need to futz with every one of them via console to undo the “auto” schedule and force particular days of the week. OR are some or many of you just run

Questions about VSA Proxies for Nutanix AHV

Hello everyone, I have a few questions regarding the use of VSA proxies. We have a medium-sized Commvault on-premise infrastructure with around 1,000 virtual machines and 100 TB of consumed storage. We are running on Nutanix AHV, and my colleague has deployed five Linux VSA proxies and five Windows VSA proxies. However, these proxies are sized as small or even extra small in some cases. I don’t really understand the need for so many VSA proxies. Is it really useful to have that many? And is there any benefit in having Windows VSA proxies? From my understanding, Linux proxies are better integrated with Nutanix AHV, right? I also noticed that during full backups, the proxies experience a very high load average, often exceeding 8 or 9, while they only have 2 vCPUs. What do you think about this setup?Would it be better to increase the resources on the Linux VSA proxies and remove the Windows ones? Thanks in advance for your insights!

Disk consolidation process causing server application timeout

Hi Team, We are experiencing an issue with one of the servers, which disconnects from the application at 5 AM EST every day. Upon investigation, we found that a snapshot removal operation or disk consolidation of the backup snapshot occurs during this time. We have a scheduled backup at 5 PM EST every day during non-business hours. However, Commvault triggers the disk consolidation operation at 4:58 AM or 5:00 AM EST every morning, causing an outage on the server during this time. Is it possible to change the disk consolidation window/schedule/pattern?

When it planned to support Proxmox hypervisor for backup?

Reason for my question is Broadcom/vmware deal. Our Customers ask if Commvault supports Proxmox Documentation.commvaut.com 11.34 show that PROXMOX is not supported. Research in comunity shows a two year old topic where someone asked the same question. Two year are a long time so I want to ask if and when Commvault plans to support Proxmox?

Current Capacity vs Storage Space and deleting VMs

Hello! I am new to comvault and currently working on a project to backup our VMs. As I have been slowly adding VM backups I have noticed that the current capacity is going up as it should and we are currently at 19.8TB out of 23TB and that is what we are licensed in backup and recovery. I got an alert saying we are over 80% utilization so I went in a retired and then deleted a few of the VMs that I had done but the capacity hasn’t gone down. How to I delete the backups that were done for those VMs or will it eventually remove the data? Also I noticed on the dashboard the the current capacity is 23TB but the total disk storage space next to is it 32TB and we are only using 7TB. What is the difference between capacity and storage space?

Support for OpenNebula (KVM) Hypervisor

Hi there, My name is Jim and I’m a Product Manager at OpenNebula - one of the most popular cloud management platforms on the market. We are an Open Source product and have a huge community of users, however in recent months we’ve had a huge influx of requests from our Enterprise Edition customers for Commvault VM backup support. I understand that in order to have this native integration it will need work from the Commvault team and perhaps you have some API standards we can implement on our side as well. We are willing to commit resources to assist and work on such an implementation and it would be great to open a discussion with the Commvault team on this. It would be great to hear if Commvault have had requests from their side as well - we would love to partner on this and share information on the Commvault / OpenNebula customers who have requested such an integration. Thanks in advance, Jim

Bubble Test Failover – Restricting Traffic with Proxy & One-Way Tunnel

Hey legends, Hope you’re all doing great! Always appreciate the insights from this community. Got a quick one for you. We got Commvault VM replication running for a SQL VM with an RPO of 4 hours—kept it that way since it’s crash-consistent, and we already got SQL agent backups (t-logs every 15 mins + daily fulls) covering us. Need to run a bubble test, and Commvault suggested a test failover + SQL restore, but the failover VM spins up with the same IP as prod on an isolated network. cant move it to routable network as we can’t have it talking to AD/DNS since there’s no firewall or ACLs to block it, so we’re thinking of using a proxy with dual NICs: 1 on isolated network and one on MA/CS network This should let us restore SQL data to the test VM without exposing it to prod. But would the failover VM still route through CS/MA and reach AD/DNS? We only want restore traffic going through, nothing else. Can we set up a one-way tunnel in Commvault to allow restores but block all other traffi
