i have to keep three servers uptodate and i would like to do this using rsync. as far as i know there are several security concerns about rsync, so is there another tool available that can do this for me ? btw ... i am using sftp to encrypt my ftp-session ? maybe there's a similiar tool for rsync available, too ?

use rsync over ssh (-e ssh) and all will be fine ;) you can use dsa/rsa keys for authentification like sftp/ssh does and that should solve your problem

You may find it a bit of a problem that to use SSH, the user account you're connecting to on the SSH server needs a shell to be able to execute the rsync command. You can take most of the risk out of this by specifying the command to be called in the SSH public key used for authentication, though. Use the following option in the public key: command="[<PATH>]rsync --server --sender -vlogDtpr <source path>" This pulls data from the server, if you with to 'push' data to the server, you'll probably need to replace the '--sender' option with something else or remove it alltogether -- I'm not looking at the man-page right now but quoting from a personal implementation reference.
