Outlook 2000 and Outlook 2003 had an add-in for "backup PST" but does
not seem to be available for Outlook 2007 BETA yet. Any word on when
it might be made available for Outlook 2007?

All that backup tool does is copy the PST to a folder of your choice on a
regular schedule. You could do the same easily by creating a Scheduled Task
in Windows.
