Run cron jobs in Windows Subsystem for Linux

If you’re running Ubuntu or another linux shell in Windows 10 via WSL (Windows Subsystem for Linux), you’ve probably wondered about using cron.

Cron is super-handy for doing things, like, running a backup.

You see, as useful as WSL is, it stores all the linuxy files in a way that is not exactly easily backup-able by File History or anything else… as far as I can tell.

Worse yet, even when you try to set up a cron job to run a backup, it doesn’t work!

What to do, what to do?
