What happens to data which is stored in store and forward and accidentally the physical machine on which ignition server is installed is restarted?

Any data in the memory buffer is lost.  
Any data in the disk cache will be kept, as they’re stored in a HSQL DB on-disk in the Ignition installation directory.
