hi there,
here's an outline of the approach I would take to configure Proxmox backup server to NFS TrueNAS:
1. First, I would make sure that both the Proxmox backup server and TrueNAS are properly set up and configured, with all necessary updates and patches installed.
2. Next, I would configure NFS sharing on the TrueNAS server, making sure to set up the appropriate permissions and security settings.
3. Once the NFS sharing is set up on the TrueNAS server, I would configure the Proxmox backup server to connect to it. This would involve specifying the NFS server address, mount point, and other settings as needed.
4. After the Proxmox backup server is configured to connect to the NFS share on the TrueNAS server, I would test the connection to make sure that the backup server is able to read and write data to the share.
5. Finally, I would set up a backup job in Proxmox to use the NFS share on the TrueNAS server as the destination for the backups. This would involve specifying the appropriate backup settings, such as the backup schedule, retention policy, and other options as needed.
Throughout the process, I would pay close attention to security and best practices, making sure that all settings and configurations are properly secured and that data is backed up safely and reliably. I would also document all the steps taken and provide clear instructions on how to maintain and troubleshoot the backup solution.
