What are the data/files that should be backed up in order to rebuild the server in case the machine fails?
Obviously, the ~/Library/Application Support/PanoramaX/Server/ folder. Anything else?
It looks like the settings are kept in:
~/Library/Preferences/com.provue.PanoramaXServer.plist
Preferences are saved by Apple, so I can’t guarantee that everything is in there, but I think it is highly likely.
Also, I think you don’t ever want to restore this file when the application is open.
Of course my recommendation for a good backup would be to back up the entire ~/Library folder.
