When I quit my last job, I was the only employee left that understood our tech stack. The other was a mechanical engineer and industrial designer. Because I felt that CEO could barely comprehend what git is or why it's important to pay AWS on time, I made a full backup of everything on a USB hard drive.

If you ever need to do this, it can be as simple as "git mirror", with extra steps for LFS and other addons.

That guy definitely did not deserve me to give him $100 of my own personal hard drive stash but out of some sick sense of professionalism I felt I had to give him a failsafe archive. Because, you guessed it, not one byte of the entire company was backed up anywhere.
