Abstract
The system, devices, and methods disclosed herein relate to data ratio reduction technology adapted to reduce storage costs by weeding out duplicative data write operations. The techniques and systems disclosed achieve deduplication benefits of smaller block, finer granularity, deduplication systems while simultaneously reducing the enormous metadata costs traditionally associated with small block deduplication. According to an exemplary 128 K block deduplication system and method, we disclose deduplication rates nearly equivalent to 4 K deduplication systems.
