There are two modes of rsync. There's the kind you use to download a CD
from an rsync server: great for unreliable connections since it will fix
a corrupted file even if you started out using a different program (e.g.
wget) to get the file in the first place.
The other mode is where it uses ssh as the transport layer so it is very
secure; everything is encrypted before going across the wire.
It's great for backups. It's great for moving config files around.
In both modes, rsync must be installed on both machines. When you tell
your rsync to copy your backup to a remote box, if the same file already
exists and you tell it to overwrite, rsync will compare the differences
and only send the differences over the wire, speeding up the transfer
greatly unless the files differ greatly.
It maintains owners, permissions, and times. All in all it's a great
tool.
Doug.
