+@chapter Overview
+
+rsync is a program for efficiently copying files or directory trees.
+rsync has many options to select which files will be copied and how
+they are to be transferred.  It may be used as an alternative to @sc{ftp},
+@sc{http}, @command{scp} or @command{rcp}.
+
+The rsync remote-update protocol allows rsync to transfer just the
+differences between two sets of files across the network link, using
+an efficient checksum-search algorithm described in the technical
+report that accompanies this package.
+
+rsync's command line syntax is analogous to @command{cp},
+@command{rcp} and @command{scp}:
+
+@example
+rsync [@var{options}] @var{source} @var{destination}
+@end example
+
+Filenames may be prefixed by a hostname to indicate a remote file.
+(@xref{Local and remote}.)
+
+Some of the additional features of rsync are:
+
+@itemize @bullet
+
+@item support for copying links, devices, owners, groups and permissions
+
+@item exclude and exclude-from options similar to GNU tar
+
+@item a CVS exclude mode for ignoring the same files that CVS would ignore
+
+@item can use any transparent remote shell, including rsh or ssh
+
+@item does not require root privileges
+
+@item pipelining of file transfers to minimize latency costs
+
+@item support for anonymous or authenticated rsync servers (ideal for
+mirroring)

+
+Probably the most common case of rsync usage is to copy files to or
+from a remote machine using @command{ssh} as a network transport.  In
+this situation rsync is a good alternative to @command{scp}.
+
+The most commonly used arguments for rsync are
+
+@table @code
+
+@item -a 
+Reproduce the structure and attributes of the origin files as exactly
+as possible: this includes copying subdirectories, symlinks, special
+files, ownership and permissions.  (@xref{Attributes to copy}.)
+
+@item -v 
+Be verbose.  Primarily, display the name of each file as it is copied.
+
+@item -z 
+Compress network traffic, using a modified version of the
+@command{zlib} library.
+
+@item -P
+Display a progress indicator while files are transferred.  This should
+normally be ommitted if rsync is not run on a terminal.
+
+@end table
+
+To make a backup of your home directory to the @file{/bkup/mbp/}
+remote machine @file{foo.example.org}, preserving the directory
+structure, use this command:
+
+@example
+rsync -avP ~ foo.example.org:/bkup/mbp/
+@end example

+@section Local and remote
+
+There are six different ways of using rsync. They are:
+
+@enumerate
+
+@item for copying local files. This is invoked when neither
+source nor destination path contains a @code{:} separator
+
+@item for copying from the local machine to a remote machine using
+a remote shell program as the transport (such as rsh or
+ssh). This is invoked when the destination path contains a
+single @code{:} separator.
+
+@item for copying from a remote machine to the local machine
+using a remote shell program. This is invoked when the source
+contains a @code{:} separator.
+
+@item for copying from a remote rsync server to the local
+machine. This is invoked when the source path contains a @code{::}
+separator or a @code{rsync://} URL.
+
+@item for copying from the local machine to a remote rsync
+server. This is invoked when the destination path contains a @code{::}
+separator.
+
+@item for listing files on a remote machine. This is done the
+same way as rsync transfers except that you leave off the
+local destination.  
+@cindex listing files
+@end enumerate
+
+Note that in all cases (other than listing) at least one of the source
+and destination paths must be local.
+
+Any one invocation of rsync makes a copy in a single direction.  rsync
+currently has no equivalent of @command{ftp}'s interactive mode.
+
+@cindex @sc{nfs}
+@cindex network filesystems
+@cindex remote filesystems
+
+rsync's network protocol is generally faster at copying files than
+network filesystems such as @sc{nfs} or @sc{cifs}.  It is better to
+run rsync on the file server either as a daemon or over ssh than
+running rsync giving the network directory.

+@cindex @command{rsh}, alternatives to
+@cindex @command{ssh} 
+
+Once installed you can use rsync to any machine that you can use
+@command{rsh} to.  rsync uses @command{rsh} for its communications,
+unless both the source and destination are local.
+
+You can also specify an alternative to rsh, either by using the
+@option{-e} command line option, or by setting the
+@var{@sc{rsync_rsh}} environment variable.
+
+One common substitute is to use @command{ssh}, which offers a high
+degree of security.
+
+Note that rsync must be installed on both the source and destination
+machines.

+This option increases the amount of information you are given during

+give you information about what files are being transferred and a
+brief summary at the end.  Two -v flags will give you information on
+network connections, files skipped, and slightly more information at
+the end.  More than two -v flags should only be used if you are
+debugging rsync.

+
+On many systems, only the superuser can set the ownership of files,
+and users can only put files into a group to which that user belongs.
+rsync works within the operating system security model.  So on such a
+system, if you copy a file which you can read but that does not belong
+to you, the destination file will be owned by you.  The only way to
+change this behaviour is to copy the file as the superuser, or to
+adjust your operating system's security model if that is possible.
+
+@quotation
+@strong{Please note:} @option{--archive} does not detect files with
+multiple names.  If any exist, they will become multiple identical
+files on the destination.  To make the names all refer to the same
+file, use @option{--hard-links}.

+Configuring rsync as a server is entirely optional.  If you just want
+to copy your own files between local directories or machines, then
+using rsync over @command{ssh} may well be sufficient.  Daemon mode
+may be useful if you wish to distribute files to a number of machines
+on a network, or to the public.

+@cindex @sc{tcp} port 873
+
+@sc{Tcp} port 873 is reserved for rsync by the Internet Assigned
+Numbers Authority (@sc{iana}) and has the service name @code{rsync}.
+However, rsync may be run on any other port using the @option{--port}
+option.
