Abstract:
A deduplication system and method involves interaction between a software-based system that manages the overall background deduplication process and a hardware-based system that includes a hardware-based filesystem manager and a hash generator. A filesystem checkpoint mechanism is leveraged to manage the background deduplication process and also to reduce processing complexity with respect to identifying chunks that are candidates for deduplication and processing such chunks.
