I think that none of this systems work reliably,
in both ways (copy on boot unless you make a new one
everytime, and copy before editing)
you can discover trashed sources too late.
I think it's better to have a manual save when important
changes are made, because the Murphy (PV) law state:
"You find the trouble just a moment to late"

Oh and with subversion it's only a matter of simple:
svn -m "" ci
for save a new version and subversion saves only changes,
so no wasted hd spaces and work well for executables
and binary data like images audio files and so on
