ZFS support on Linux OS

Hi!

I’m working with customer who is interested in ZFS support on Linux platform (Debian specifically). Now I’ve been browsing through docs and as I suspected ZFS is not a supported FS for Guest OS file restore with FREL.

https://documentation.commvault.com/2022e/expert/32330_live_file_recovery_for_vmware.html

So naturally FS iDA is the way to go. I was surprised when I checked the requirements page and wasn’t able to find ZFS as supported FS on Linux platform

https://documentation.commvault.com/2022e/expert/3146_linux_file_system_agent_system_requirements_02.html

It is however supported on platforms like FreeBSD and Solaris

https://documentation.commvault.com/2022e/essential/108954_what_is_backed_up_for_unix_file_servers.html

I’ve been curious so I tested this on FREL ova with some additional packages allowing for ZFS to work on OS side, but even then browse is not working on ZFS volumes. I also tested this on Linux FS iDA and had some more luck, cause I was able to backup and successfully restore some data from ZFS volume.

So what I would like to ask is if ZFS is really not supported on Linux OS or is it just a piece missing from documentation?
