<para><application>rsync</application> is a replacement for <command>rcp
|
|
</command> (and <command>scp</command>) that has many more features. It
|
|
uses the "rsync algorithm" which provides a very fast method of syncing remote
|
|
files. It does this by sending just the differences in the files across the
|
|
link, without requiring that both sets of files are present at one end
|
|
of the link beforehand.</para></sect3>
