<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>
