rsyncing via cron

[Nori Heikkinen <nori@sccs.swarthmore.edu>]

how can i create a cron job to rsync to a remote system?  i use
ssh-askpass, but since cron runs as root, i get

Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,password,keyboard-interactive).
rsync: connection unexpectedly closed (0 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at io.c(150)

is there a way to do this?

thanks,

</nori>
