In my eyes, it would be a great feature, if it is possible to rebuild the database with only the dicom-files.
So, it's only needed to archive new studies, which is possible to do on dvd. if the systems crashes, you just copy back the dicom-files and rebuild the db.
it's the same when changing e.g. the port of the server: if you forget to uncheck "drop tables...", then you need to restore the db, if you 've backuped it...
