QTS 4.2.1 NAS OS by Qnap

Qnap Systems, Inc. announced QTS 4.2.1 – the NAS OS – with more features and improved apps that empower users to achieve more with both data management and office applications.

With features and upgraded applications, QTS 4.2.1 makes for smarter and smoother data management experiences with stronger cloud service security.

“We are pleased to release QTS 4.2.1 and believe that it will allow our users to achieve more in their business and home life. We received significant feedback from QTS 4.2.1 Beta reviewers, and this provided constant encouragement for our development team to provide better QTS functionality for users,” said Tony Lu, product manager, Qnap.”Designed with a smarter and smoother user interface, QTS 4.2.1 is a reinvented NAS OS for more immersive experiences and stronger security.“

Network and virtual switch, proxy server
and Windows previous versions support for SMB application
Network and virtual switch integrates powerful network management functions to provide a comprehensive network topology overview and enhances port trunking connectivity. Virtual switches enable users to build isolated LAN environments with the built-in DHCP server for better data security. An example usage case would be restricting access to IP camera surveillance footage. The proxy server application fully supports caching to record content accessed from the Internet. This saves bandwidth, and speeds up network transmission. The proxy server application provides an intuitive interface to simplify proxy server settings on your NAS, enabling to operate your own proxy server in a few clicks. The proxy server provides cache and connection controls for Internet services. For companies that need a boost to web response time and security, this application can be leveraged to make your NAS a web proxy server to protect other devices in your local network from Internet attacks. Moreover, QTS 4.2.1 with snapshots allows Windows users to restore files directly using the ‘Previous Version’ feature to save time and effort without requiring support from IT staff.

Useful Qsirch, hybrid backup sync and Qmail for data management
Qsirch 2.1 brings improvements to the convenient company’s exclusive whole-NAS search function. File indexing runs as a background task, allowing users to oversee the indexing progress and status. This feature can also exclude files from indexing, so users can filter search results by file type including photos, music, videos, and documents. The content preview presents thumbnail previews for photos, videos, and PDFs, making searching and browsing through huge amounts of results much faster and easier.

Hybrid Backup Sync consolidates backup, restoration and synchronization functions into a single QTS application for you to easily transfer data to local, remote and cloud storage as a comprehensive storage and DR plan.

Qmail is an email client that allows users to access various email accounts or switch to other accounts. Supporting major email services complying IMAP protocols, Qmail allows automatic email backup from cloud services to firm’s NAS. Qmail also enables users to manage different email accounts easily and select files from a NAS as attachments.

Note that both Hybrid Backup Sync beta and Qmail will soon be released in the QTS App Center.
