Backing up 300TB TrueNAS with Veeam

I’m running a TrueNAS Scale 24.04 file server (virtualized on ESXi) with around 300TB of data that I want to back up using Veeam. The challenge I’m running into is around licensing and agent support, since I can’t install the Veeam Agent directly on TrueNAS and I don’t want to back up the data with NFS/SMB due to licensing constraints.

After some research, I’m considering setting up a Linux VM to act as a proxy, mounting the share and then backing it up with the Veeam Agent from there.

Is there a better way to approach this? I’d appreciate any insights or examples. Thanks!

Running TrueNAS bare metal and backing up by sending snapshots to an offsite TrueNAS.

Maybe add some rsync or some S3 backup to something like Backblaze.

I know this is probably not what you want to hear, but something like backups I would want as less complexity as possible. Linux VM to act as a proxy sounds like a complexity nightmare. Both performance and stability wise.
