Fast and efficient content-defined chunking for data deduplication. Java implementation of FastCDC as library.

DedupBench is a benchmarking tool for content-defined chunking techniques used in data deduplication. It currently supports eleven unique CDC techniques and five different vector instruction sets.

Fast content-defined chunking in Go.

CDCZip is a deduplication filter meant for use as long range match finder preprocessor for use alongside other compression algorithms.

Find (partial content) duplicate files.

Print FastCDC rolling hash chunks and checksums.

A Rust library for Content-Defined Chunking (CDC).

Synclet is a content-defined, chunk-based file synchronization and backup tool that detects and syncs only the actual changes—efficiently, intelligently, and reliably.

cdcgo is a Go library that implements FastCDC , a high-performance content-defined chunking algorithm for deduplication and data storage.
