In CLIPS 6.3, there are two C functions, EnvGetInstancePPForm and EnvGetFactPPForm, that will return the printed representation of an instance or a fact. You can iterate over the facts/instances and save that representation to later recreate the facts/instances. The drawback is that the buffer passed to the functions is fixed to whatever it's initially set. In CLIPS 6.4, the equivalent functions are InstancePPForm and FactPPForm and these use a data structure that will expand the string buffer needed...

The ppfact function allows you to specify a logical name, so if you want to use a custom router you can iterate over the facts and use ppfact to direct the output to a logical name recognized by the router.
