Fast Disaster Recovery with Snapshots
The TS-431XU supports block-based Snapshots, which can record and save the state of the file system and the metadata of the files outside the file system at any time. In the event of an unexpected NAS failure or if struck by a ransomware attack, the snapshots remain intact, allowing you to quickly and easily restore the system back to a previous normal state. You can preserve and restore multiple versions of the same file, folder or even the entire volume. The TS-431XU supports up to 64 snapshots per volume or LUN (up to 256 in total). Snapshot Replica facilitates double protection that replicates snapshots to a remote QNAP NAS or server.
Note: The Snapshots feature will be available from QTS 4.3.4.

High reliability design ensuring business continuity
The business-ready TS-431XU 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-431XU delivers high reliability and efficiency with support for multiple port-trunking modes including fail-over support.
VJBOD: use NAS to expand other NAS capacity for maximizing sharing economy
Besides using expansion enclosures, there is an additional option to expand NAS storage capacity. QNAP VJBOD (Virtual JBOD) is network-based JBOD, allowing you to expand the storage of a QNAP NAS with multiple QNAP NAS units. The TS-431XU offers great potential for economically expanding the storage of other QNAP NAS with VJBOD, and to create virtual storage pools and volumes on virtual disks for operating NAS services.
1. ARM-based NAS currently does not support VJBOD "Host" function to utilize other NAS storage space.
2. The remote QNAP NAS must support iSCSI and Storage Pools and use QTS 4.2.1 (or newer).
