ssh/rsync

I finally got bugzilla working at my job. I had to learn about mysql and apache to get anywhere, so it took me days. I'm working now on backup for the bugs database. I would like set up a cron job to use rsync over ssh to backup a dump of the bugs database to a backup host. What I don't understand is how to deal with passphases in a shell script. Or is there a better way to go about this? Any ideas? -- -ashley One of these days I'm going to completely organize my life.
