openssh unix dev - Apr 2002 - Password in SSH scrips

Hi,

    Suppose my backup server has to copy every day at the end of the night,
all files from the Web Server.  So every day I will have a script that
copies files using SCP. 
    I  USE  HP-UX .

    But this script must work without anyone entering passwords. I know that
SCP will need Passwords. How can I make a script with this feature ? Using
keygen ?
If posssible, describe with details how can I make some script, for example:

- cd /tmp
- lcd /tmp
- scp list.cfg root at mactest
- echo OK

    I have the same problem for SFTP. Can anyone help me ?

Att,

I do something very similar with rsync using ssh as an rsh replacement. 
Using rsync you don't have to script a session and you also get some
additional atime/mtime and delete features.
