Hi Tractng and all, I hope this message finds you well.
When putting Veeam backups on an NFS share, here's how it works:
Veeam is a Windows Server, NFS directly has (historically) been a little rough with Windows. (Windows Server 2012 does it much better but not yet supported directly)
To get to an NFS share, we add a Linux system (Can be a VM) to the inventory of Veeam.
This puts an agent in that Linux system to interact with Veeam and directly access the NFS share as a mount (Add your nfs mount command as a startup)
Then you can define a repository as a path on the Linux system in Veeam
Then backups can go there.
Is it a Deduplication appliance? If so, not all of them support NFS flock, a distributed locking protocol (Data Domain in particular). So, be mindful of the mount command.
Here is a Word document with a few screenshots of the Veeam configuration and the NFS mount script:
One little known benefit to using NFS... If Active Directory is failed and it's backups are on a CIFS share... How do you authenticate
