Rsync

Internal

• Linux

Overview

rsync copies files to or from a remote host, or locally on the current host. It does not support copying files between two remote hosts. rsync may connect to the remote system either using a remote-shell programs, such as ssh or ssh, or directly to the rsync daemon running on the remote system, via TCP.

The remote-shell trans-

      port is used whenever the source or destination path contains a single colon (:) separator after a host specification.  Contacting an rsync daemon directly happens when the source or destination path contains
      a double colon (::) separator after a host specification, OR when an rsync:// URL is specified (see also the "USING RSYNC-DAEMON FEATURES VIA A REMOTE-SHELL CONNECTION" section for an exception to this latter
      rule).

      As a special case, if a single source arg is specified without a destination, the files are listed in an output format similar to "ls -l".

      As expected, if neither the source or destination path specify a remote host, the copy occurs locally (see also the --list-only option).

SETUP

      See the file README for installation instructions.

      Once installed, you can use rsync to any machine that you can access via a remote shell (as well as some that you can access using the rsync daemon-mode protocol).  For remote transfers, a modern  rsync  uses
      ssh for its communications, but it may have been configured to use a different remote shell by default, such as rsh or remsh.

      You can also specify any remote shell you like, either by using the -e command line option, or by setting the RSYNC_RSH environment variable.

      Note that rsync must be installed on both the source and destination machines.
