Adding a QNAP NAS as Backup Storage to Proxmox Backup Server

If you use Proxmox Backup Server (PBS) and want to safely store your backups on a QNAP NAS, just follow these user-friendly steps. All IPs and folder names below are examples—use your actual network values.

1. Create a Share and Enable NFS on QNAP

• Login to your QNAP control panel and create a shared folder (e.g., PBSBackup).
• Go to the “NFS Access” settings.
• Add your PBS server’s IP address (e.g., 192.168.1.100).
• Set permission to read-write (RW) and choose “Do not squash any users” (no_root_squash).
• Save your settings.

2. Mount the QNAP Share on PBS

• Open a terminal on your PBS server and, if needed, install NFS support:

  apt update
  apt install nfs-common -y

• Create a mount point:

  mkdir -p /mnt/qnap-backup

• Mount the share (example):

  mount -t nfs 192.168.1.50:/share/PBSBackup /mnt/qnap-backup

• For permanent mounting after reboot, add this line to /etc/fstab:

  192.168.1.50:/share/PBSBackup  /mnt/qnap-backup  nfs  defaults,_netdev  0  0

3. Create an Empty Folder for PBS

mkdir /mnt/qnap-backup/proxmox-backup

4. Add the Datastore via the PBS Web Interface

• Log in to the PBS web UI (https://pbs.example.com:8007).
• Go to Datastore > Add > Directory.
• For Backing Path, enter /mnt/qnap-backup/proxmox-backup.
• Choose a name and add it.

5. Final Checks

• Run ls -l /mnt/qnap-backup/proxmox-backup in the terminal to check access.
• Use the PBS web interface to create a test backup and verify that data is written to the QNAP share.
