rsync backup script

VERY simple rsync script. It rsyncs a remote directory across to a local one. There's no special reason why I did this, other than I wanted to run the script on my local machine. It could just as easily rsync a local directory to a remote one.

#!/bin/sh
export RSYNC_RSH=/usr/bin/ssh
origin=remote.machine.com # the remote machine to rsync from
user=miguel # the remote user
rsync -aHPvz "${user}@${origin}:/remote/files/" "/local/files/"

I run ssh-keygen -t rsa and create a password-less key on the remote machine, and copy the .pub file into my authorized_keys. This way I can run this script on a cron, say in the middle of the night, and not have to be around to enter a password at the prompt.
