I only save my *.r script source files, daily. It's not too heavy.
I tried to precede each file, and each function,
with at least 1 comment-line filled with key-words.
(Plus other comments)
This trick works for all languages.
Even some years later, this allows to retrieve forgotten functions.

any search engine, like the simple Windows search menu is ok.

comment lines can be used for other powerful tricks.
