Reduce the impact of ransomware or system failure with Snapshots

The TS-431XeU supports snapshots, which can record the system status and data at any single moment*. If the system unexpectedly fails or is infected with ransomware, you can instantly restore files from a snapshot. The intuitive snapshot tool in the QTS Storage Manager can be used to take snapshots of your data, and restore data from snapshots if necessary. Always take regular snapshots to ensure the safety of your files and data.

* For a single volume/LUN, up to 64 versions are supported. For the whole NAS, up to 256 versions are supported. Snapshot support will be added to the TS-431XeU in the upcoming QTS 4.3.4.

High reliability design ensuring business continuity

The business-ready TS-431XeU is designed to provide 24/7 operations and services. The support for comprehensive RAID configurations and hot-swapping allow for replacing hard drives without service interruption. QNAP's advanced RAID recovery technology also helps if any healthy drives are accidentally removed from a degraded RAID volume. The system can be recovered by reinserting the wrongly-removed hard drives so the data can still be accessible. The TS-431XeU delivers high reliability and efficiency with support for multiple port-trunking modes including fail-over support.
