Take a look at DumpSave. Doing

DumpSave["file.mx", "Global`"]

will write out all of your data and variables in the Global`
context to a binary file that can be re-loaded using Get. There
are a few things this will not preserve. It will not save and
restore the history stack. Nor will it re-open any file streams
that are open when DumpSave is executed.

It is also important to realize the format used by DumpSave is
not portable from one computer system to another.
