Backup TrueNas Core with Veeam

I use TrueNas Core and I would like to backup all my NAS with Veeam backup and replication 12.
How can I proceed ?
Do I need to add my TrueNas like an “unstructured data source” ?
If so, what option should I choose in next window? File server, File share or NAS filer ?
Thanks for your help

Thats a Veeam issue, not a TrueNAS issue.

But someone who uses Veeam may answer anyway

For information I am new user with TrueNas and fresh install on a physical server.
I set on Veeam a backup from Microsoft VSS snapshot but I have this error :

10/3/2025 6:51:32 PM :: Processing \NAS04\CIFS_TEST Error: Failed to add volume [\NAS04\CIFS_TEST] to the VSS snapshot set
The given shadow copy provider does not support shadow copying the specified volume.
–tr:Failed to add volumes to the snapshot set.
–tr:Failed to perform pre-backup tasks.

Is it possible to backup from VSS snapshot with my TrueNas ?

Thanks
