Rsync

rsync is a command-line utility for synchronizing files and directories across different locations, such as local machines or remote servers, by transferring only the differences between the source and destination. As a powerful tool for data replication, backup, and migration, rsync is widely used in the tech community to efficiently manage large datasets, automate file transfers, and ensure data consistency across distributed systems, making it a valuable asset for developers, system administrators, and DevOps teams.
