After just permanently losing all my SMSs and contacts, I've become super paranoid about the prospect of this happening again.

Does anyone know of a way to initiate the built-in backup from the commandline? I think it must be possible, because the PR1.2 and PR1.3 updates kicked off an auto-backup before they installed.

I'm hoping I can script it so cron/ProfileMatic kicks off a backup at 3am every morning...
