Simple Minimal Backup Solution

Last night I was writing a script and it made a directory literally named "~" on accident. It being 3am I did an rm -rf ~ without thinking and destroyed my home dir. Luckily some of the files were mounted in docker containers which my user didn't have permission to delete. I was able to get back to an ok state but lost a bit of data.

I now realize I really should be making backups because shit happens. I self host a pypi repository, a docker registry both with containers and some game servers in and out of containers. What would be the simplest tool to backup to Google drive and easily restore?
