Snapshot Replica
• Snapshot Replica is a snapshot-based full backup solution for QTS.
• With Snapshot Replica you can back up a volume or block-based LUN to another storage pool, either
on the same NAS or on a different QNAP NAS, using snapshots.
• Backing up data with Snapshot Replica reduces storage space and bandwidth requirements, and
simplifies data recovery.
Protection Levels
Snapshot Replica can back up your snapshots to another storage pool on the local NAS, or to a remote
NAS. These different backup configurations provide different levels of data protection.
