An IT team needs to synchronize large amounts of data between two nodes on the company's local network. This data changes daily and it is not feasible to copy the entire directory tree each time…

rsync (remote synchronize) is designed for efficient delta transfers, copying only the differences between source and destination files, which is ideal for large datasets with daily changes and when full copies are not feasible. It can also securely transfer files over SSH.

scp (secure copy protocol) copies entire files, which would be inefficient for synchronizing large datasets with minor daily changes.

fsync is a system call that forces all in-core modified block pages for a file to be written to disk, not a tool for network file synchronization.

netcp is not a standard or commonly recognized command-line utility for file synchronization or copying in Linux/Unix environments.
