Terramaster new TOS 7 NAS Software Beta Ready to Test

December 15, 2025 | TerraMaster, a professional storage brand dedicated to delivering innovative solutions for home users, businesses, and developers, today officially launches the public beta of TOS 7. This highly anticipated release, developed over nearly two years by a team of more than 100 engineers, not only celebrates the 15th anniversary of the TOS operating system but also marks its stunning transformation from a simple storage tool into a full-featured private cloud platform. Looking back to 2011, TOS 1.0 debuted alongside TerraMaster’s very first NAS product. Back then, the interface was bare-bones—you could create shared folders, enable SMB, and add a handful of user accounts. It was simple, almost primitive, but it laid a rock-solid foundation.

Fifteen years later, TOS has evolved into its 7th generation. A single TerraMaster NAS can now effortlessly serve as a file server, virtual machine host, developer workstation, online collaboration platform, or even an enterprise-grade permissions fortress. Throughout this journey, we’ve kept asking ourselves one core question: How should a device that people interact with dozens of times a day actually be designed to truly fit the way you work?

With TOS 7, the answer is finally here—and it’s within reach. Built on a brand-new kernel (upgraded to Linux 6.12) and a completely refreshed design language, TOS 7 features 90% newly drawn icons and over 1,000 refined interaction details, making every operation more intuitive, smoother, and faster than ever before.

Transform into an All-Powerful Host and Unleash Unlimited Possibilities

TOS 7 marks the first time we’ve opened full root access while seamlessly integrating official Ubuntu repositories. Developers can now instantly install Nginx, Node.js, Python environments, databases, or compilers using apt—turning your NAS into a fully SSH-accessible Linux server with zero jailbreaking and zero third-party plugins. It’s all native.

The built-in Virtual Machines (VMs) module lets you deploy Windows, Linux, macOS (on supported hardware), or any distro with a single click. Whether you’re building test environments, migrating legacy systems, isolating applications, or creating a compact private cloud, TOS 7 squeezes every last drop of performance from your hardware and turns your NAS into a true flexible computing hub.

Collaboration with Zero Barriers – Your Data Stays Local Forever

Say goodbye to the old “download-edit-upload” hassle. TOS 7 natively integrates online Office tools that support real-time viewing and multi-user collaborative editing of Word, Excel, and PowerPoint files. Documents are saved directly on your NAS—no third-party cloud, no extra subscription fees. Changes sync in seconds, boosting team productivity by 100%. Your data, always under your control.

Search as Smooth as Thought – Instant Response for Millions of Files

Our in-house global search engine combines inverted indexing, kernel-level real-time file monitoring, and asynchronous I/O caching to deliver second-level full-disk scans for millions of files — 10× faster than TOS 6, with 120% higher search accuracy. No need for exact filenames; just type a keyword and get precise hits instantly. File management efficiency jumps by 60%.

Granular Permissions Down to the Thread – Rock-Solid Security

The permission system has been expanded from 3 basic types to 13 combinable domain-based ACL policies, with fully customizable rules (e.g., “department can only read/write specific folders and is prohibited from deleting”). Setup time is 99.6% shorter than TOS 6 — complex authorizations are done in seconds — striking the perfect balance between ironclad data security and flexible access control.

How to Access the Terramaster TOS 7 Beta?

After over 300 days of meticulous development and the collaborative efforts of hundreds of engineers, we have developed the all-new TOS 7 for you—more user-friendly and visually refined. With over 50 new features and more than 1,000 detailed optimizations, TOS 7 delivers a faster response, smoother interactions, and a more elegant interface. Designed with forward-looking interaction concepts, it achieves a comprehensive transformation from the inside out, ushering you into a refreshing new era of operation.

Warning:
1. This update is only applicable to version 6.0.794 or higher.
2. TOS 7 adopts a completely new permission management method. After the update, permission conversion is required. It is recommended to choose automatic conversion. This process is time-consuming, please wait patiently (for example, approximately 400,000 folders may take about 3 hours).
3. After the update, besides the storage pools and volumes in normal use, the Storage Manager interface may display several corrupted storage pools and volumes caused by abnormal operations (such as directly pulling out disks) in TOS 6. If you confirm they are no longer in use, you can delete them directly.

Important Notes:
1. The Beta version is an early testing release and may contain defects. It is not suitable for production environments or storing critical data. Do not use it for official business operations.
2. The update is designed to preserve data on hard drives. However, as a precaution, it is essential to back up all important data before proceeding.
3. If your shared folders were generated by Snapshot, their permissions will need to be reconfigured after the update.
4. After updating, all existing share links, desktop notifications, recent access history, application logs, system logs, and scheduled SMART test plans will be cleared.
5. Following the update, the Resource Dashboard, navigation bar icons, and Debug mode will revert to their default states.
6. The newly added cloud drive mounting features for Alibaba Cloud Drive and S3 protocol in File Manage are not yet complete and are temporarily unavailable.
7. Due to security protocol changes, some applications will require updates or reconfiguration after the update. Community applications may need to be re-downloaded and reinstalled.
8. If you have previously modified the BIOS boot order, please adjust it before updating to ensure the TOS system drive has priority over other boot devices (such as USB drives). Failure to do so may cause the system to boot into the installation interface after the update.
9. System configurations from TOS 6 cannot be directly restored to TOS 7. A new configuration backup will need to be created after the update.
10. Before updating, please ensure your main volume (typically volume1) has at least 3 GB of free space. Insufficient space may cause the update to fail.
11. After updating, the device’s IP address may change. Please use the TNAS PC client to search for and reconnect to your device.

TerraMaster est un fabricant de solutions de stockage qui propose notamment des NAS. Ce dernier vient d’annoncer l’arrivée de TOS 7, son nouveau système maison. Le constructeur promet une refonte majeure avec de nouvelles fonctionnalités, une interface revue et plus fluide. Regardons ensemble les évolutions de ce dernier…

TOS 7, le nouveau TerraMaster

TerraMaster vient d’annoncer une mise à jour importante de son système (TerraMaster Operating System) : TOS 7. Actuellement, c’est TOS 6 qui anime les NAS du fabricant et il faut avouer que cette précédente version avait apporté un vent de fraicheur. Un an après, la nouvelle version est annoncée…

Quelles nouveautés attendre dans TOS 7 ?

TOS 7 devrait marquer une véritable évolution pour les utilisateurs de NAS TerraMaster. Le fabricant annonce plus de 50 nouvelles fonctionnalités et plus de 1 000 optimisations. L’interface utilisateur a été entièrement revue : design modernisé, navigation simplifiée et expérience plus cohérente.

L’objectif : rendre l’utilisation des NAS TerraMaster plus intuitive et agréable, tant pour les particuliers que pour les professionnels. Cette refonte place désormais la marque dans la course face aux acteurs historiques du secteur.

TerraMaster a mis en ligne une page dédiée sur TOS 7 et une vidéo… et le moins que l’on puisse dire, c’est que le fabricant a mis la barre très haute.

Interface et ergonomie

Avec TOS 7, TerraMaster revoit l’expérience utilisateur. On passe rapidement sur les icônes qui ont été redessinées… on appréciera d’apprendre que plus de 50 nouvelles fonctionnalités ont été ajoutées et 1 000 optimisations destinées à améliorer la fluidité et la réactivité du système. L’interface propose une navigation totalement personnalisable. Le fabricant annonce une hausse de 60 % de l’efficacité globale.

Productivité et collaboration

Le gestionnaire de fichiers évolue en profondeur avec l’apparition des modules My Files et Desktop, permettant notamment le montage à distance simplifié et une navigation plus rapide via des vues par onglets ou fractionnées. TerraMaster annonce la prise en charge native des fichiers ISO (sans passer par Dossier partagé), ainsi qu’une corbeille unifiée.

TOS 7 intègre aussi de nouveaux outils de collaboration en ligne : il est désormais possible d’éditer en temps réel des documents Word, Excel et PowerPoint sans téléchargement préalable.

Administration et sécurité

Sur le plan de la gestion au quotidien, TOS 7 introduit une refonte complète du gestionnaire de stockage. L’utilisateur bénéficie de vues visuelles claires des volumes, d’outils de migration et de suppression de disques améliorés, ainsi que d’une optimisation adaptative des grappes RAID.

La gestion des permissions devient plus fine, avec jusqu’à 13 types de droits personnalisables, répondants aux exigences des utilisateurs dans les environnements de plus en plus complexes. Autre nouveauté importante, TOS 7 propose un contrôle réseau précis, en offrant la possibilité de limiter la vitesse des ports et d’allouer la bande passante par service ou par appareil. Ce système évite qu’un seul service ne monopolise les ressources et garantit une utilisation équilibrée du réseau.

Développement et personnalisation

Le Centre d’applications s’enrichit de 10 nouvelles catégories, d’un déploiement Docker en un clic et d’un suivi détaillé des journaux pour une meilleure supervision. Pour les utilisateurs avancés, TerraMaster introduit un mode développeur complet : accès root, compatibilité avec Ubuntu et prise en charge des machines virtuelles (VM), sans passer par un logiciel tiers.

Cette ouverture à la virtualisation permet d’isoler des applications ou de tester des environnements distincts.

En synthèse

Avec TOS 7, TerraMaster franchit un cap en combinant refonte graphique, performance accrue et nouvelles fonctionnalités. Les outils de collaboration, la gestion réseau avancée et la virtualisation rapprochent les NAS TerraMaster des solutions professionnelles les plus complètes.

Pour l’instant, TOS 7 n’est disponible qu’en version Preview, réservée aux volontaires et pouvant contenir des bugs. Aucune date de sortie officielle n’a été annoncée… et il pourrait s’écouler plusieurs mois avant la version finale, comme ce fut le cas pour TOS 6.
