manpagedescription()
-Rsync is a program that behaves in much the same way that rcp does,
-but has many more options and uses the rsync remote-update protocol to
-greatly speed up file transfers when the destination file is being
-updated.
-
-The rsync remote-update protocol allows rsync to transfer just the
-differences between two sets of files across the network connection, using
-an efficient checksum-search algorithm described in the technical
-report that accompanies this package.
-
-Rsync finds files that need to be transferred using a "quick check" algorithm
-that looks for files that have changed in size or in last-modified time (by
-default). Any changes in the other preserved attributes (as requested by
-options) are made on the destination file directly when the quick check
-indicates that the file's data does not need to be updated.
+Rsync is a fast and extraordinarily versatile file copying tool. It can
+copy locally, to/from another host over any remote shell, or to/from a
+remote rsync daemon. It offers a large number of options that control
+every aspect of its behavior and permit very flexible specification of the
+set of files to be copied. It is famous for its delta-transfer algorithm,
+which reduces the amount of data sent over the network by sending only the
+differences between the source files and the existing files in the
+destination. Rsync is widely used for backups and mirroring and as an
+improved copy command for everyday use.

Some of the additional features of rsync are:
manpagesection(ADVANCED USAGE)
-The syntax for requesting multiple files from a remote host involves using
-quoted spaces in the SRC. Some examples:
+The syntax for requesting multiple files from a remote host is done by
+specifying additional remote-host args in the same style as the first,
+or with the hostname omitted. For instance, all these work:
-quote(tt(rsync host::'modname/dir1/file1 modname/dir2/file2' /dest))
+quote(tt(rsync -av host:file1 :file2 host:file{3,4} /dest/)nl()
+tt(rsync -av host::modname/file{1,2} host::modname/file3 /dest/)nl()
+tt(rsync -av host::modname/file1 ::modname/file{3,4}))
-This would copy file1 and file2 into /dest from an rsync daemon. Each
-additional arg must include the same "modname/" prefix as the first one,
-and must be preceded by a single space. All other spaces are assumed
-to be a part of the filenames.
+Older versions of rsync required using quoted spaces in the SRC, like these
+examples:
-quote(tt(rsync -av host:'dir1/file1 dir2/file2' /dest))
+quote(tt(rsync -av host:'dir1/file1 dir2/file2' /dest)nl()
+tt(rsync host::'modname/dir1/file1 modname/dir2/file2' /dest))
-This would copy file1 and file2 into /dest using a remote shell. This
-word-splitting is done by the remote shell, so if it doesn't work it means
-that the remote shell isn't configured to split its args based on
-whitespace (a very rare setting, but not unknown). If you need to transfer
-a filename that contains whitespace, you'll need to either escape the
-whitespace in a way that the remote shell will understand, or use wildcards
-in place of the spaces. Two examples of this are:
+This word-splitting still works (by default) in the latest rsync, but is
+not as easy to use as the first method.
-quote(
-tt(rsync -av host:'file\ name\ with\ spaces' /dest)nl()
-tt(rsync -av host:file?name?with?spaces /dest)nl()
-)
+If you need to transfer a filename that contains whitespace, you can either
+specify the bf(--protect-args) (bf(-s)) option, or you'll need to escape
+the whitespace in a way that the remote shell will understand. For
+instance:
-This latter example assumes that your shell passes through unmatched
-wildcards. If it complains about "no match", put the name in quotes.
+quote(tt(rsync -av host:'file\ name\ with\ spaces' /dest))
