Rsync : If the above rsync session itself gets interrupted, you can resume it as many time as you want by typing the same command. ![]() Scp : scp command line tool cannot resume aborted downloads from lost network connections Rsync : rsync is comparatively more optimise and speed Scp : scp is relatively less optimise and speed scp will always use SSH as underlying transport mechanism which has both integrity and confidentiality guarantees, so that is another difference between the two utilities.ĭifference b/w scp and rsync on different parameter 1. Be sure to always use rsync via SSH (as in the examples from the question above), not via the rsync protocol, unless you really know what you're doing. See Sid Kshatriya's answer.įinally, note that rsync:// the protocol is similar to plain HTTP: unencrypted and no integrity checks. If the transfer is interrupted, you can resume it where it stopped by reissuing the command. It is an excellent tool to keep two directories synchronized over a network.Īlso, when dealing with large files, use rsync with the -P option. As mentioned, on multiple invocations it will take advantage of data already transferred, performing very quickly and saving on resources. It's simpler to use, and in those cases rsync optimizations won't help much.įor recurring tasks, like cron jobs, use rsync. Commands that you type once in a while on your interactive shell. In summary, use scp for your day to day tasks. It supports complex filter rules, runs in batch mode, daemon mode, etc. rsync has a plethora of command line options, allowing the user to fine tune its behavior. Rsync will write data to a temporary file T, and then replace the destination file B with T to make the update look "atomic" to processes that might be using B.Īnother difference between them concerns invocation. If the destination file B already exists, the delta transfer algorithm will make sure only differences between A and B are sent over the wire. Rsync will check files sizes and modification timestamps of both A and B, and skip any further processing if they match. But it employs a special delta transfer algorithm and a few optimizations to make the operation a lot faster. ![]() Rsync also copies files locally or over a network. It performs a plain linear copy, locally, or over a network. Scp basically reads the source file and writes it to the destination. The major difference between these tools is how they copy files.
