Enhance the Safety of your Data with a Next-Generation File System

Superior storage technology and optimised snapshot technology are the cornerstones of the Btrfs file system, which is what TerraMaster’s NAS unit relies on for advanced data protection, prevention of data corruption, and minimal maintenance expenses. Use of this file system promotes high data integrity, all the while promoting flexibility and efficiency in the areas of data protection and data recovery.
Optimised snapshot technology generates 512 snapshots for every shared folder, and up to 8,192 overall system snapshots. In this way, users can benefit from flexible, storage-saving data protection.
Since data recovery takes place at the file or folder level, businesses can also benefit from enhanced flexibility and efficient data recovery.
