[GNC] Logs and Backups

David,

Actually, I was more trying to remind Ken that he could just turn off 
AutoSave altogether by setting the Interval to zero.  That way he has 
complete *manual* control over how many saves are done, and when -- 
rather than being dependent on user activity or the calendar.  One thing 
that might have caused confusion is calling those save files "backups".

The reason I like having those saves is because it gives me the chance 
to go back in time in a granular way if I need to see what a certain 
action or transaction of mine might have done to possibly cause a 
problem.  But it's definitely not a recourse in the event of a 
catastrophic failure.  If the disk dies, those saves die right along 
with it.  I think we all realize that.  My backup program copies those 
90 some files off to a completely separate physical disk at the end of 
each day.  That other disk is the *actual* backup.
