Scheduled Backups If you need to schedule backups, you can make use of Mark Malson’s excellent (and free) “Cron.” This faceless background application constantly scans its own preferences folder for aliases to items you want scheduled. These aliases are labelled according to a Unix-like format. For example, if you wanted a certain SwitchBack document to be launched at 5pm every weekday, you would place an alias to that document in the “Cron Preferences” folder, and label it “0 17 * * 1-5”. For more details see the documentation supplied with “Cron”, available at the usual mirror sites of Sumex and UMich.
