That is how it is supposed to work, yes.  If the data really isn't in your
Data.fs (as opposed to being there, but inaccessible somehow) then that's a
serious Zope bug.  This may sound stupid, but have you tried using a
different browser or aggressively clearing the cache on your current
browser?  Sometimes a browser has handed me a days-old folder contents view
from its cache, but refreshing fixes it.

You should take another copy of your original Data.fs and run Tranalyzer on
it (http://www.zope.org/Members/tsarna/Tranalyzer) for clues as to what's
really in it.  If it shows no transactions more recent than the two-days old
ones, let us know.

Backups are never a bad idea.  You shouldn't have to export, though;
copying Data.fs, even while the system is running, should give you a good
backup.
