DESCRIPTION
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 already
exists.
The rsync remote-update protocol allows rsync to transfer just the dif-
ferences between two sets of files across the network link, using an
efficient checksum-search algorithm described in the technical report
that accompanies this package.
Some of the additional features of rsync are:
o support for copying links, devices, owners, groups and permis-
sions
o exclude and exclude-from options similar to GNU tar
o a CVS exclude mode for ignoring the same files that CVS would
ignore
o can use any transparent remote shell, including rsh or ssh
