Safer Encryption

The new TOS allows users to import or self-issue security certificates and to assign these to specific services to establish a secure transmission channel between the server and users. This helps prevent transferred data from being leaked or altered in any way.

More Flexible Startup and Shutdown Processes

Whether the user is far away from the device or right next to it, it is easy to start the TNAS at any time, anywhere with the Wake-on-LAN (WOL) feature. WOL helps protect the device and prolongs the service life of hard drives by allowing shutdown without inconvenience. Whenever the files in the TNAS are required, any instruction sent to it will wake it up, even if it is switched off. TNAS mobile applications supporting WOL are already in production.

Two New Channels, IPv6 and IPv5

The system supports the latest IPv6 channel, which has a wider address range and allows more channels to be added. Using this not only solves problems related to the number of network address resources available but also removes barriers to connecting various devices to the Internet, based on its integration with IPv4 applications and services.

Better Technical Support

To help users troubleshoot problems when using the TNAS device, the new TOS features system problem logging reports. After a problem is selected by the user, a log report is generated automatically that can be exported to the technical support team with a single click. This allows better analysis of system failure causes and more rapid provision of appropriate solutions, allowing users to solve problems more easily.

Improved Storage Resource Management

To facilitate the preferred allocation of resources by users, TOS offers a Quota for shared folders. Where Quota is enabled, the available capacity of shared folders is limited, and such folders will not be copied, uploaded or backed up beyond their resource quota. Quota for shared folders is only applicable for btrfs file systems.

More Secure Data Protection

Data is a precious asset for both enterprises and individuals. To prevent ransomware attacks or data damage due to human error or malicious deletion, TerraMaster has launched a unique Hyperlock-WORM file system that allows users to create unmodifiable and undeletable memory spaces at designated locations. These can then be used to prevent important data from being accidentally or maliciously altered for a specified period, protecting the core value of enterprises.
