Linux SCP Command Detailed

SCP is a shorthand for secure copy, which is used to remotely copy files under Linux, and the SCP transfer is encrypted and may slightly affect the speed. In addition, the SCP does not account for the resources, how much system load, at this point, rsync is far less than it. Although Rsync is a bit faster than SCP, rsync can cause hard disk I/O when there are too many small files, and the SCP basically does not affect the normal use of the system
