It also, I would assume, is why .Mac fails to sync Yojimbo so often.
Instead of syncing 1,000 small files, it is trying to sync one
monolithic DB.  I can't get it to work with .Mac or SyncTogether's
latest beta.

Um... are you sure about Outlook?  I know it didn't used to be that
way, as I would routinely have to make sure that the Outlook PST
stayed below 2gb.

Entourage doesn't store a single email per file.  It too uses the same
Huge Database Concept.

I certainly wouldn't be using Yojimbo or any other DB app while
SuperDuper et al are running.  Sure it might not throw an error but
you still risk problems.

I run SuperDuper at night when I go to bed and then have it
shutdown/sleep the computer.  I quit all my running apps except SD!
