...The tool maintains chunk fingerprints and a manifest so it can de-duplicate across versions and even across different files that share regions of content. This approach makes it well suited for large logs, VM images, and binary assets where small edits would otherwise force full re-uploads. The implementation focuses on being robust over unreliable networks with resumable transfers and integrity checks that verify every chunk. Operationally, it behaves like a straightforward CLI: point it at a source and destination and it negotiates what needs to move, minimizing CPU and bandwidth where possible.
