rsync and passwords

[todd at aristesoftware.com (Todd Cary)]

To synchronize my server with the "standby" server, I run the following:

rsync -a -e ssh /home/ 192.168.0.22:/home/

As expected, I am asked for a password from the destination computer.  
Is there a way to avoid that so I can make a crontab to run the rsync 
nightly?
