*The TS-251B’s hardware provides H.264 hardware decoding, encoding and transcoding capabilities. However, playback quality may vary due to factors including playback software, file formats, system usage, and available bandwidth.
PROTECT IMPORTANT DATA WITH SNAPSHOTS
Snapshots help protect your data by fully recording the NAS system state and metadata. If your files are accidentally deleted or modified or if they’re locked by ransomware, you can use snapshots to quickly restore files to a previously-recorded state. QNAP snapshots are block-based and only record the changed data. Not only does this save storage space but also reduces the time required to back up and restore data. The TS-251B supports up to 1,024 snapshots per NAS and up to 256 snapshots per volume or LUN.
CONSOLIDATED NOTIFICATIONS AND EXTRA NAS SECURITY
QTS 4.3.5 provides various mechanisms to ensure the data saved on your TS-251B is carefully safeguarded, including the brand-new Notification Center that consolidates system logs and notifications into a single app and the Security Counselor that checks for weaknesses and offers helpful security recommendations.
NOTIFICATION CENTER
Consolidates system logs and notifications for all NAS apps into a single app with flexible rule settings, facilitating smooth and easy NAS management.
SECURITY COUNSELOR
Checks for weaknesses and offers recommendations to enhance NAS security. Anti-virus and anti-malware software is also integrated within Security Counselor to ensure the complete protection of your NAS and data.
