3-2-1-1-0 Is the New 3-2-1 – Maximizing Data Security on ASUSTOR

ASUSTOR's MyArchive air gaps and WORM immutable storage, combined with PQC-Ready technology and advanced RAID support build the ultimate frontline against threats to data security.

Taipei, Taiwan - 12 March 2026 – As ransomware attack methods become increasingly sophisticated, the traditional 3-2-1 backup rule faces new challenges. With this in mind, we here at ASUSTOR are changing our messaging to actively promote the new 3-2-1-1-0 backup principle for increased data security. With 3-2-1-1-0, you still need at least three copies of data, on two different types of media with one offsite, but additionally, one copy must be offline or immutable while ensuring backups are verified with zero errors. With MyArchive, easy backup methods, WORM immutable storage technology, forward-looking post-quantum cryptography technology, and advanced RAID configurations, your ASUSTOR comes with maximum hardware resilience to keep your data safe. ASUSTOR helps you implement the latest and greatest cybersecurity standards, ensuring the safety of digital assets even in extreme environments. 
 
To achieve the extra one and zero in 3-2-1-1-0, ASUSTOR provides strong hardware support. For those who require high end performance, the Lockerstor R Pro Gen2 series prioritizes performance and security. New to ASUSTOR is support for RAID 50 and RAID 60 configurations for combining efficient transmission and even higher or dual protection. This ensures stable and uninterrupted operation even in extreme situations involving massive data transfers. 
 
In terms of software, ASUSTOR’s WORM technology creates a virtually impenetrable wall around data. Once data enters protection mode, no one, not even administrators, can modify nor delete it. Even more forward-thinking, ASUSTOR is currently the only NAS manufacturer that is Post-Quantum Cryptography Ready, also known as PQC Ready. With this in mind, ASUSTOR integrates post-quantum cryptography algorithms to prepare for the long-term information security of users, helping to prevent confidential data from being leaked. 
 
Addressing the most challenging aspect of cybersecurity defense is physical isolation. ASUSTOR’s MyArchive technology offers a definitive solution for this. MyArchive allows hard drives to be directly converted into removable backup drives, and after backup, they can be physically extracted and stored offline in a safe location, creating an air gap that ensures ransomware cannot touch your data. ASUSTOR's Snapshot Center, using Btrfs, creates virtual snapshots in a fast and space-efficient manner. In the event of accidental deletion, ransomware attacks, unintentional or unauthorized modification, restoration of data is easy and Snapshot Center can turn back the clock to a previous state for an easy frontline to data security. 
 
Through the high level of integration of software and hardware, the 3-2-1-1-0 backup principle is no longer an expensive privilege reserved for large enterprises. Through the continuous evolution of ADM, ASUSTOR equips all models across its NAS product range with the ability to build a top-tier defense system, providing individual workers and small businesses with absolute resilience to face future data security challenges.
