Whoops is my data recovery program, which I initially built for my own uses (I use Arq5 nowadays). Anyway, this program watches over files, scans them every second and checks if they are different. If so, they will ask you if you want to restore the previous data. The project performs better when run on local storage, because unfortunately repl.it’s emulated storage isn’t that great! When you look through, you will find a .py file called jfuncs. This just contains the code for my database helper, which aids the project in overwriting values. In case you are, I would not recommend using this software to back up your files. as there are much better programs out there. If you are interested in building your own, I would recommend looking at checksums or hashes of files instead, as these are much more efficient than reading the entire file.
