Systems and methods for efficient backup deduplication

A system for efficient backup deduplication, the system comprising:

• an identification module, stored in memory, that identifies a file to be divided into chunks for deduplication;
• a requesting module, stored in memory, that requests, from a server, a chunk size to use when dividing the file for deduplication by submitting at least one attribute of the file to the server, the server selecting the chunk size based at least in part on a projected chunk reuse rate when the file is deduplicated according to the chunk size;
• a receiving module, stored in memory, that receives from the server, in response to requesting the chunk size, the chunk size to use when dividing the file for deduplication;
• a division module, stored in memory, that divides the file for deduplication into a plurality of chunks according to the chunk size, thereby reducing memory storage requirements in the system;
• at least one physical processor configured to execute the identification module, the requesting module, the receiving module, and the division module.

A non-transitory computer-readable medium comprising one or more computer-readable instructions that, when executed by at least one processor of a computing device, cause the computing device to:

• identify a file to be divided into chunks for deduplication;
• request, from a server, a chunk size to use when dividing the file for deduplication by submitting at least one attribute of the file to the server, the server selecting the chunk size based at least in part on a projected chunk reuse rate when the file is deduplicated according to the chunk size;
• receive from the server, in response to requesting the chunk size, the chunk size to use when dividing the file for deduplication;
• divide the file for deduplication into a plurality of chunks according to the chunk size, thereby reducing memory storage requirements in the computing device.
