If I have systems that are based on realtime data, how can I ensure that all the information that is current is redundantly stored in a file? So that when the program starts again, it uses this information to initialize itself back to where it was when it closed.

I know of xstream and HSQLDB. but wasn't sure if this was the best option for data that needs to be a literal carbon copy.
