If you do, read carefully the documentation on intervals and automation. It took me an embarassing number of tries to get the intervals and crontab entries to mesh so it worked the way I wanted. It's not really that difficult (and it's pretty well documented), but I managed to combine a misreading of how often and in what order the rsync wrapper was supposed to run with my chronic inability to grok crontab specifications.
