A secure backup center with snapshot protection

  • Windows® and Mac® backup

    Use the license-free QNAP NetBak Replicator utility to back up and restore files from Windows® computers. Time Machine® is supported for backing up Mac® computers.

  • Snapshots for Volume & LUN

    Snapshots are essential for NAS data protection, and their block-level feature makes it a dependable data protection method in the face of growing ransomware threats.

Multi-point file backup, access, and sync

The TS-451D2 centrally stores data and files, and supports common file sharing protocols, including SMB/CIFS, AFP and NFS for Windows®, Mac®, and Linux®/UNIX® devices. Coupled with Qsync (a utility that transforms a QNAP NAS into a secure, high-capacity data center for file synchronization), any file uploaded to the TS-451D2 becomes available for all connected devices (such as computers, laptops, and mobile devices). Hybrid Backup Sync helps you easily backup or synchronize data on the TS-451D2 to another QNAP NAS, remote servers, or cloud storage for disaster recovery. Additionally, QuDedup technology greatly improves the efficiency of multi-version backup to the destination storage, while optimizing storage utilization. You can install the QuDedup Extract Tool on your computer and restore deduplicated files to their normal status.
