Well I often work in "dual mode", meaning that I am editing a script 
file and doing something via the GUI on the open datafile at the same 
time (or intermittently). Then from time to time it happens that I rerun 
the script file to try out the changes and then what I did last via the 
menus is lost.

The script has an 'open' command to reload the datafile because some 
time ago you recommended that for clearing some gretl internals. Maybe 
this is now simply redundant? Then that would be a workaround. (Although 
I still wouldn't like the idea to automatically discard unsaved changes.)

Exactly. So it's not really a backup but rather a just-in-case file :-)

thanks,
