Protects your sensitive data with file encryption

When sharing sensitive or confidential files on your TS-431X3, you can enhance data security by using File Station to encrypt them 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: Computers are required with Windows 8 (or later) OS and macOS 10.12 (or later) OS.

Protect data against malware with Snapshots

Snapshots help protect your data by fully recording the NAS system state 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-431X3 supports up to 64 snapshots per volume/LUN, and up to 256 snapshots in total.
