The German Version 9 from http://www.paragon-software.com/de/home/db-express/features.html cannot backup Windows 7 partitions, only the English Version 10 from http://www.paragon-software.com/home/db-express/ can do Windows 7 backups.
But all editions of Windows 7 itself can backup Windows 7 partitions, see (1) and (2)
Cons:
You will need to register for a serial number before starting with installation, but it's well worth the minimal effort.
Without a product key and serial number the installation process will be interrupted without information about this fact at the beginning of the installation.
