why can't you import a pst file? Isn't that one of its purposes --
to be able to back-up and retrieve files if needed?

Exporting and importing are for changing between Outlook and non-Outlook
formats, not for backing up. You don't export a Word document to a Word
document, do you? Backing up a PST is EASY. With Outlook closed, just COPY
it.
