[protege-discussion] Protege on Linux server without graphical interface

Hi Katja,

I've been running Protege 3.4 as a server for about a year now on a  
windows server and this runs without the GUI in what it calls  
"headless mode". So, it's definitely possible. I do "manage" some  
changes, e.g. to forms, by stopping the server and running Protege in  
stand-alone mode.
However, to do backups, I simply get the database to run scheduled  
backups and I have some scripts that run automatically to copy  
the .PPRJ file as a backup.
Backing up the database - just set up a scheduled MySQL backup - will  
cover your ontology in terms of both the Instances and the Classes.  
So, any changes made by the Protege clients will be covered by the  
database backups.
To make sure that any changes you make to the Forms are not lost, you  
need to backup the .PPRJ file.
That will do it.

Hope this helps - let me know if I've missed something
