You’ll need a File Recovery Enabler to do file lever restores from Linux machines.

Restoring Guest Files and Folders (commvault.com)

To add, its less about the OS version and more about the file system used. I believe XFS should still be default, and that is definitely supported for file recovery as long as you have a FREL deployed.

Here are a couple of short videos which can help get you started:

Make sure, you use FREL with RHEL/CentOS 8.X for Linux 8.X VMs.

Hi,

Thanks for your answer, but regarding compatibility , is version 8.3 (Red Hat) supported? In the past someone of support team told us that was not (in that time). Where can we find this information? (compatibility matrix?).

It depends on the file system version used in Linux VM.

@Luiz Silva Granular recovery is supported for Linux centos/rhel 8.3 guests. The only requirement is that the FREL should be running 8.2 or higher. This is because the default XFS version and format has changed between RHEL 7 and 8.
