on os9, i used CopyAgent to perform automatic backups. this program is not available for osx. i'm wondering what everyone's using. i'm using .mac to back up 20 meg of my most valuable stuff. but for all my user data, i've got about 30 gig that i can back up to an external firewire drive. i'd like something that allows me to back up different folders w/ different options (e.g. schedule, copy policies). thanks!
