This has been on my to-buy list for a while. Something I should probably do, because while recovery from the built-in recovery interface is fine, having an offline bootable backup is also great. It also doesn't interfere with having Time Machine be the "standard" backup.

I could probably setup a calendar appointment to dump a bootable image once a month to an external disk.

While I agree that SuperDuper! is worth buying, it is free to use for whole-disk backup/cloning. The paid version enables smart copying (that is, only copying files changed since the last backup).

You can just use the UI to make whatever schedule you want (monthly, daily, every Monday, etc.). I think it edits your crontab behind the scenes. I set it to daily, but you could set whatever you want. You can even have multiple schedule entries, similar to cron.

Edit: Yeah, the bootable backups have saved me more than once. It's great to just be able to keep working even when the system disk is kaput.
