Setting up Proxmox Backup Server (PBS) with an NFS repository provides a method to store backup data on network-attached storage using the NFS protocol. This involves configuring the NFS share on your storage device and integrating it into PBS as a usable datastore. This approach allows for centralized backup storage leveraging your network infrastructure.
To configure this, first ensure your network storage device is set up to export an NFS share with read/write permissions for your Proxmox Backup Server. On the PBS interface, you add a new datastore, selecting NFS as the storage type. You will need to provide the IP address or hostname of the NFS server and the specific path of the exported share. PBS will then manage this remote location for storing backup archives. Properly configuring permissions on the NFS server side is paramount to ensure PBS can write data reliably. Additionally, ensuring sufficient network bandwidth between PBS and the NFS server is critical for backup and restore performance, especially with large datasets. Utilizing NFS for PBS datastores is a cost-effective way to leverage existing network storage resources, providing a flexible and widely compatible solution for your backup strategy. This method simplifies storage management by consolidating backup targets onto a dedicated storage system accessible over the network.
