diffssend

diffssend is a command-line utility designed for efficiently transferring large files or directories over a network. It utilizes a differential approach, meaning it only sends the parts of a file that have changed since the last transfer, significantly reducing bandwidth usage and transfer times. This makes it particularly useful for incremental backups or synchronizing large datasets where frequent updates are expected.

The core functionality of diffssend relies on a comparison algorithm that identifies differences between the source and destination files. Once these differences are determined, only the modified data blocks are transmitted. The recipient then reconstructs the updated file by applying these changes to its existing copy. This process is typically performed over standard network protocols like SSH, ensuring secure and reliable data transfer.

diffssend is often employed in scenarios where traditional file synchronization tools might be too slow or consume excessive bandwidth. Its ability to handle large files and its efficient delta-transfer mechanism make it a valuable tool for system administrators, developers, and anyone managing significant amounts of data that require regular synchronization across different locations. The tool aims to provide a streamlined and resource-conscious method for keeping files and directories up-to-date.
