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 modified data. Not only does this save storage space, but it also reduces the time required to back up and restore data. The TS-431KX supports up to 32 snapshots per volume or LUN, and up to 64 snapshots in total.
