The site seems to have gone down at the time of this writing. I am looking for a backup alternative to Time Machine because it seems to have a memory leak. The fraction of available memory just shrinks, even if I quit everything. I've turned Time Machine backups off in System Preferences and rigged launched to back up only 3 times a day, and now I'm no longer having to reboot every other day.

A shame, because TM seemed to work perfectly in Snow Leopard.
