store the contents of target’s RAM in frequent intervals

[Sandeep222]

Hi,
             I would like to know if there is any possibility for adding
functionality in GDB which could store the contents of target’s RAM in
frequent intervals so that, when accidentally switched off or shut down of
an embedded target, we can resume the execution of the program from where it
earlier stopped (i.e previous save point). Conceptually It is somewhat
similar to the Hibernate function used in Windows xp, Service pack 2. I was
thinking of inducing this functionality for embedded targets in particular.  
             Need comes for test cases which runs for days, or even weeks.
Suppose, on 2nd day of program run, somebody switches it off, it should be
able to resume from that location after it's switched on. 
Thanks. 
Reg, 
Sandeep
