With reference to a few posts on this forum (inc. http://www.zionworx.org.uk/forum_3/viewtopic.php?f=20&t=786 recently) an easy backup option to USB key (with maybe upload to internet FTP URL) would be a good product addition.
The above post points out that the database is in a hidden folder, and though getting to the location is easy (unhide, or just type in the path in Explorer), having a backup option would be good becuase it would backup the correct files whilst Zionworx is running.
