7.1.2  Data backup in HMI Embedded 
All furnished drives are available for a data backup.  
As a general rule, all modified files and programs are stored directly on the 
CompactFlash card in a permanently defined tree structure. From there, they can 
be copied to other memory locations over the set up drives. 
 
Procedure 
Use the same procedure as described in the “Series start-up” section.
