Modern businesses and workgroups face the challenge of finding a robust storage solution that can scale with the exponential increase in digital content their organization creates. From shared documents, old archived files and large rich media files, through to enterprise databases and core applications data, this challenge will only become more acute. Deploying an appropriate IT environment with a reliable, affordable and expandable storage solution is business critical. The ability to securely store, share and back-up digital assets has become one of the most important tasks for an SMB IT administrator, choosing the right option will significantly enhance business productivity and crucially offer a reliable disaster recovery solution in an age when downtime of any nature impacts profitability.
The QNAP TS-421U Turbo NAS is an all-in-one rack mount network attached storage (NAS) server optimized for small and medium businesses looking for an affordable yet high performance network storage solution. The TS-421U can hold up to 4 hard drives and is designed to be easily installed in the server room and configured with up to 12TB of storage capacity. The TS-421U is an ideal solution for centralized data backup, cross-platform file sharing, iSCSI/IP-SAN storage combo solution and a number of business applications. Moreover, the TS-421U offers exceptionally low power consumption, reliable system operations and capacity expandability.
Besides, the intuitive MyCloudNAS service simplifies the process of publishing content residing on the TS-421U over the Internet and helps the IT administrator create private cloud storage in just a few simple steps. The mobile app QMobile provides users with an iOS or Android mobile device with a convenient way to access the TS-421U on the go.
Large Capacity Storage and File Sharing
Cross-platform Sharing with Antivirus
The TS-421U supports SMB/CIFS, NFS, and AFP protocols for file sharing across Windows, Mac, Linux/UNIX networks. User accounts and shared folders can be created via the user-friendly web-based interface without IT expertise. The integrated antivirus solution for the TS-421U ensures business continuity by offering detection against the latest viruses, malware, worms, and Trojan horses.
Windows Active Directory (AD) and LDAP Directory Service
The Windows AD and LDAP (Lightweight Directory Access Protocol) directory service features enable the IT administrator to retrieve user accounts from Windows AD or LDAP-based directory server to the TS-421U, reducing time and effort in account setup. Users can use the same login name and password to access the TS-421U. In addition, the TS-421U can also be configured as an LDAP server and allows devices with LDAP protocol enabled to be joined in the directory and share the same user accounts and groups.
Shared Folder Aggregation
Access the shared folders of other servers on Microsoft Networking through the "portal folder" on the TS-421U. This saves the time and effort in logging in multiple servers one by one.
ISO File Archiving and Sharing
The TS-421U supports mounting ISO images of CD and DVD discs as network shares for data archiving, storage, and sharing. This feature saves the space for storing the physical discs, reduces the risk of data loss caused by disc wearing and tearing, and enhances the efficiency of data sharing on business network.
Advanced Folder Permissions
Advanced folder permissions allow users to configure folder/subfolder access to the TS-421U. With this feature enabled, users can manage the folder permissions from Microsoft Windows or the web-based management interface of the TS-421U easily.
Secure Data Storage and Access
- Policy-based Unauthorized IP Blocking
The IT administrator can allow, deny or auto block specified IP address or network domain which attempt to connect to the TS-421U via SSH, Telnet, HTTP(S), FTP, Samba, or AFP
- Remote Login
The TS-421U supports remote login via SSH (secure shell) or Telnet connection.
- SSL Security (HTTPS)
The TS-421U supports HTTPS connection. The IT administrator can upload a secure certificate and RSA private key in X.509PEM format issued by a trusted provider to allow access to the TS-421U via secure SSL login.
- Secure FTP
The TS-421U offers secure data transfer with SSL/TLS (explicit) encryption. Passive FTP port range setup is also supported.
- Encrypted Remote Replication by Rsync
The data on the TS-421U can be backed up to or from another Turbo NAS or Rsync server over the network securely.
- Shared Folder Management
The IT administrator can select to hide or show selected shared folders of the TS-421U on Windows network.
- User Authority Management
Create multiple users and specify their password, quota, and user groups by simply uploading the batch files in TXT or Excel CSV format to the NAS.

Backup Center for Business
Well-rounded Backup Solutions
The TS-421U offers the IT administrator flexible server backup solutions, including encrypted remote replication, Real-time Remote Replication (RTRR), and cloud-based storage backup. Windows users and Mac users can use QNAP NetBak Replicator utility and Time Machine respectively to back up data to the TS-421U. Furthermore, the TS-421U supports third party backup software such as Veeam Backup & Replication and Acronis True Image.
Disaster Recovery Solution
The TS-421U offers users peace of mind, business continuity, and high availability of data by providing the ability to recover their data from disasters.
Real-time Remote Replication
Real-time Remote Replication (RTRR) provides real-time or scheduled data replication between the TS-421U and a remote QNAP NAS, an FTP server, or an external drive.
iSCSI LUN Snapshot/Backup
Server virtualization reduces IT expenditure yet provides flexible server management. Adopting a proper data protection and disaster recovery for virtual machines has become vastly important. The TS-421U has taken iSCSI LUN backup/restore to a whole new level with snapshot technology. The IT administrator can use the LUN snapshot to back up contents in the LUN to various storage destinations, including Windows shared folders via SMB/CIFS, Linux shared folders via NFS, or local shared folders on the TS-421U.
Cloud Storage Backup
Get ready to send private data to the clouds! The TS-421U supports Amazon S3, ElephantDrive and Symform cloud storage backup which have several backup modes including real-time, scheduled backup and versioning control so that the data can be restored from any point of time. With ElephantDrive cloud storage can be monitored through a web browser. An extra set of all of the data stored will always be available, so remote data recovery is quick and simple.
Backup to external drive via USB3.0
The IT administrator can connect external storage devices to the Turbo NAS via the eSATA or USB ports and back up data in the NAS shared folders to the external devices. Three backup modes are provided: instant, scheduled, and automatic backup.
The Turbo NAS features USB 3.0 ports for high speed backup to external hard drives. EXT3, EXT4, NTFS, and HFS+ file systems are supported to ensure compatibility with Windows, Mac OS X, and Linux operating systems.
