well the answer is in what you wrote: while the RESTART is backup-ed  
normally (and you can loose it)
RESTART_HISTORY is by default not backup-ed, and dumps the restart  
only at certain amount of iterations.
You can use the setting I sent you for both section and get the same  
result.
Up to you which one you want to choose.

This is the REFTRAJ ENSEMBLE in the MD module.
I'm not sure it is fully integrated in such a way that you can read  
WFN restart
files at each iteration (I would say you cannot at the moment)..  
but.. you can of
course use the trajectory and re-compute the wfn optimization at each  
step..

Keep in mind that the speed of computers today is such that does not  
make
any sense to store thousands of restart files when you can re- 
evaluate them
quickly.
