DumpSave is very useful in that it is very fast, and creates a binary 
file (with suffix .mx) that can be read back with Get. The read back is 
also very efficient.

However, you will need to specify what exactly needs saving (see the 
help for this function), but if your notebook is reasonably well 
organised, this may not be hard.
