Taipei, Taiwan, October 30, 2017 – QNAP® Systems, Inc. today released the QTS 4.3.4 beta for ARM-based QNAP NAS. As data security is a fundamentally essential requirement for NAS, QNAP makes snapshots a standard feature to help mitigate the growing threat of ransomware. QNAP has been working alongside AnnapurnaLabs, an Amazon company, and from QTS 4.3.4, QNAP NAS with AnnapurnaLabs processors can support snapshots with only 1GB RAM, making snapshot protection more accessible to users of entry-level NAS. QTS 4.3.4 for x86-based NAS and other ARM-based NAS models will be released soon with comprehensive and accessible snapshot protection.

QNAP continues to explore the potential of the ext4 file system, empowering QNAP NAS with high performance and outstanding snapshots manageability. Users can also set snapshot reservation space to ensure enough dedicated space for saving snapshots.

“Every aspect of QTS 4.3.4 was built on the foundation of comprehensive feedback and communication from business, individual and home users. We believe that our objective of developing QTS as ‘designed from user experience’ delivers a complete NAS operating system with the most professional storage services available,” said Tony Lu, Product Manager of QNAP, adding “Whether you are an existing or new QNAP NAS user, we are confident that you will feel the remarkable additions and improvements throughout QTS 4.3.4.”
