I wonder why the file BACKUP.HISTORY is so importent that it blows the whole 
import process if it is not there. 
I do not have this file because i retrieved the backup by performing an offline 
backup. In this case there is no BACKUP.HISTORY file.

If i create a empty file with the name BACKUP.HISTORY in the backup folder, 
everything works fine.
