Rsync Algorithm
The Rsync algorithm is an efficient data synchronization and file transfer algorithm that minimizes data transmission by only sending the differences between source and destination files. It works by computing checksums for fixed-size blocks on the source and comparing them to the destination, then transmitting only the mismatched blocks and new data. This makes it highly effective for incremental backups, remote file updates, and network-efficient data replication.
Developers should learn the Rsync algorithm when building applications that require efficient data synchronization over networks, such as backup systems, version control tools, or distributed file systems. It's particularly useful in scenarios with limited bandwidth, large datasets, or frequent small updates, as it reduces transfer time and resource usage compared to sending entire files.
