How can anyone answer this question - as you have supplied no code! I 
must say, however, I would not store important results in binary format 
- it probably takes up less disk space, but if something goes wrong, you 
have nothing. If you ARE going to use DumpSave, I would at least check 
that it is working as you expect early on in the process.

Are you performing a calculation that takes an excessively long time to 
run, and if so, are you sure this could not be speeded up in some way so 
that there is no need to do the calculation in several stages.

If you supply more details of your problem, I am sure someone here will 
be able to help - although probably not to salvage your previous results!
