Protects your sensitive data with file encryption

When sharing sensitive or confidential files on your TS-431K, you can enhance data security with File Station by encrypting files into .qenc files and set a password. The file recipients need to download and install QENC Decrypter on their computers and enter the correct password to decrypt, view, and use encrypted .qenc files.

Note: The computer must run on Windows 8 (or later) or macOS 10.12 (or later).

Protect data against malware with Snapshots

Snapshots help protect your data by fully recording the NAS system status and metadata. If a file is accidentally deleted or modified, you can use snapshots from the Storage & Snapshots Manager or the File Station to quickly restore files to its previously-recorded state. QNAP snapshots are block-based and only record changed data. Not only does this save storage space, but it also reduces time required to back up and restore data. The TS-431K supports up to 16 snapshots per volume/LUN, and up to 32 snapshots in total.

Multi-point file backup, access, and sync

HBS (Hybrid Backup Sync) consolidates data backup, recovery, and synchronization, allowing you to easily backup or sync data to another QNAP NAS, and remote server or cloud storage (e.g. Dropbox® or Google® Drive) to build a reliable disaster recovery solution. Qsync turns the TS-431K into a secure, high-capacity data center for file synchronization. Any file uploaded to the TS-431K will be made available for all linked devices, such as computers, laptops, and mobile devices. You can also sync shared folders or create team folders to enhance team collaboration.
