[gentoo-server] cron not doing backup

[Ben Munat]

Discovered that cron is running my backup script but not making the 
backup. The output shows up in the log, but the last increment is the 
last time I ran the script from the command line. I'm pretty sure that 
the problem is that cron can't make the connection to the server... I'm 
running this script on my backup machine, using an RSA key to log-in to 
the server. It works great when I run it from the command line as root, 
but when cron does it, it fails.

So, the question is, how do I set up cron so it can use the RSA key I 
generated for this... how can cron log into my server as root?
