TerraMaster TOS System 15th Anniversary Milestone: TOS 7 Beta Now Open Worldwide

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.

Those Long-Awaited “Finally Fixed!” Moments

TOS 7 obsessively polishes the everyday pain points that used to drive you crazy:

· Smart ISO mounting: Double-click and0 and it just opens—no manual steps, instantly speeding up OS installs and virtualization workflows.

· Unified Recycle Bin: One central trash across all shared folders; recover accidentally deleted files with a single click.

· Per-port bandwidth limits: Throttle specific apps or devices so BT or backups never hog the entire connection.

· Revamped Notification Center: Subscribe only to the alerts you care about, 40+ event types, one-click jump straight to the issue—troubleshooting has never been faster.

· Files & Desktop overhaul: New “My Files” and “Desktop” spaces with remote mounting and full GUI support; tabbed browsing + split-view makes juggling multiple folders a breeze.

· Expanded app ecosystem: App Center now has 10 new categories, one-click Docker deployment, real-time logs, plus distributed TNAS.online networking for blazing-fast global access.

· Mobile-first experience: Deep integration with the TNAS mobile app—total control from anywhere.

And yes—every single one of these features is completely free. As long as your TerraMaster hardware supports TOS 7, everything is unlocked for every user—no limits on user accounts, no feature tiers, no “enterprise-only” upsells. One TerraMaster device should give you its full potential, period.

Over the past 15 years, we’ve forged TOS from a basic storage backend into your personal all-in-one digital powerhouse. Fire it up and you’ll realize it’s not just a device—it’s your digital fortress.

We invite TNAS users worldwide to jump into the public beta right now: test it, break it, tell us what’s wrong, and help us make it perfect together. If you already own a TerraMaster, first update to the latest TOS 6, then join the beta—full instructions are on our website.

Thank you for being with us these 15 years. The road ahead is long, but TOS 7 is ready to take off.
