TerraMaster File System Snapshot DR Tool Based on BTRFS File System

TerraMaster Technology Co. Ltd. launches the TerraMaster File System Snapshot (TFSS), a DR tool developed based on the BTRFS file system.

TFSS takes a snapshot of the entire file system that provides accurate data history which in turn helps in preventing data loss caused by errors or cyberattacks such as malwares, ransomwares, and viruses.

The TFSS provide data protection and recovery tools while improving data integrity. Every year, more than one million devices around the world are ravaged by cyberattacks resulting to millions of losses. It aims to provide DR and restoration against such scenarios and protect users from data loss.

Key features:

• Protects entire file system
  Once TFSS is enabled, it will automatically snapshot all volumes in the TNAS device using the BTRFS file system, without the need to manually set the snapshot destination and storage location, and all data under the file system will be protected. Each file system can retain up to 1,024 snapshots, providing user with adjustable data protection capabilities that save storage capacity and meet snapshot performance requirements.

• Minimal resource requirement
  The TFSS snapshot function uses the BTRFS COW (copy-on-write) feature, so snapshots can be created almost instantly. Each snapshot needs dozens of K storage space, and it can provide secure data protection without occupying a lot of disk space.

• Efficient data restoration
  Snapshot files are stored as read-only file types in hidden system directories, and once created, the content cannot be modified. When a disaster occurs or is attacked by ransomware, through TFSS’s intuitive graphical interface, user can browse historical versions of file system snapshots and restore data to the state before the disaster with a few clicks.

• Custom snapshot schedule
  TFSS provides a customizable snapshot task schedule, and the snapshot time, period, and frequency can be customized. With a snapshot schedule, user will no longer be afraid of ransomware attacks and give user data peace of mind.

The TFSS is available as one of the backup options for TNAS models running on TOS 5 (company’s NAS OS).
