This allows you to leverage QNAP’s robust storage capabilities alongside Proxmox’s powerful virtualization features.
Virtualization Station
Virtualization Station is QNAP’s built-in hypervisor that allows you to run multiple virtual machines directly on compatible QNAP NAS devices. It supports various operating systems like Windows, Linux, and others, providing an easy-to-use web interface for VM management. This feature enables users to combine storage and virtualization in a single device without needing separate hardware.
QNAP Bootable USB or iSCSI
QNAP devices can use bootable USB drives to load alternative operating systems or tools like Proxmox, allowing flexible system setups without altering the NAS OS. iSCSI enables QNAP NAS to present storage as a block device over the network, which Proxmox can use as direct VM storage. Together, these methods enhance Proxmox and QNAP integration by expanding storage and boot options.
External Mini-PC or Server with QNAP as Storage
You can run Proxmox on an external mini-PC or dedicated server while using the QNAP NAS solely for storage via network protocols like NFS or iSCSI. This setup separates compute and storage, optimizing performance and flexibility. It allows Proxmox to handle virtualization tasks while leveraging QNAP’s reliable, centralized storage capabilities.
Why Use Proxmox for NAS?
While QNAP is a robust NAS solution, Proxmox adds:
- Virtualization capability beyond QNAP’s built-in VM tools
- More flexible VM/container management
- Advanced clustering and backup tools
- Customizable networking and firewall options
What Is the Difference Between QNAP and NAS?
A NAS (Network Attached Storage) is a general term for any device designed to provide centralized storage accessible over a network. It allows multiple users or devices to store, share, and manage files in a convenient and centralized way. NAS devices typically include basic file sharing, backup capabilities, and sometimes media streaming functions.
QNAP, on the other hand, is a specific manufacturer and brand that produces NAS devices with a strong focus on advanced features, performance, and expandability. QNAP NAS units run on their proprietary operating system (QTS or QuTS hero) and offer extensive application ecosystems, including virtualization support, container hosting, surveillance management, cloud sync, and multimedia services.
As legacy services like Skype die or become obsolete, platforms like QNAP continue to evolve, offering integrated communication, storage, and cloud solutions in one device—making them more future-ready than traditional standalone apps.
Configuring QNAP for Proxmox Backups
You can configure your QNAP NAS as a backup target for Proxmox by:
- Creating an NFS or CIFS/SMB Share on your QNAP.
- Mounting the Share in Proxmox via the GUI or /etc/pve/storage.cfg.
- Assigning it as a Backup Storage in Proxmox.
- Scheduling VM Backups to your QNAP share.
Can You Run a NAS on Proxmox?
Yes, you can run a NAS solution within Proxmox, such as:
- TrueNAS CORE or TrueNAS SCALE
- OpenMediaVault
- Nextcloud on Ubuntu/Debian
Proxmox Backup Server with QNAP Integration
You can deploy Proxmox Backup Server (PBS) and use QNAP as the backup storage target:
- Install PBS as a VM or on a separate host.
- Connect QNAP via NFS or SMB to the PBS.
- Configure datastore paths in the PBS interface.
- Integrate PBS with your main Proxmox VE for backups.
Which OS Does QNAP Use?
