Hi all, 

 

I had a question. 

Could not find it with a search, so maybe someone can help me out. 

Does CommVault support Virtual Trusted Platform Module (vTPM)?

I know Rubrik does not support it yet. 

 

Best Regard

What hypervisor support are you interested in? AHV by any chance?

HI Jacek, 

 

Sorry it's for/in VMware.

Hi All,

 

I also have the same questions. I have a customer who has VTPM on some of their VMware VMs and we are getting 

Error Code

[91:598]

Failure Reason

Unable to download the configuration file for virtual machine [VM]. The remote server returned an error: (500) Internal Server Error.

 

many thanks,

Rich

Hello ​@Richard Kent & ​@sakuragi

 

Even though our documentation doesn't specify that we support vTPM, this is infact supported for VMware I believe since March 2023 (might be longer). 


It’s supported and nothing special required apart from required permissions and depends on use case like if Hotadd VSA access then it must encrypted.

Check below BOL for details.

Hello ​@hewhomustnotbenamed,

 

I raised a support case a few days after my last posting and they provided the following:

 

“Currently, Commvault does not support the backup and restore of VMware VMs with vTPM enabled. This limitation arises because the vTPM data, including crucial encryption keys, is not accessible to third-party backup software like Commvault. To proceed with backups, you would need to disable the vTPM feature on the VMs.”

 

This was as of September 2024 and I have not seen any change to this in recent update release notes.

 

Thanks.
