Syncthing and other similar software are great, but sometimes you just want a simple, lightweight, and fast way to mirror things, specially if the remote and/or local machines have limited resources.
Here is my ultra minimalistic set and forget (I hope) 2-in-1 rsync based mirror script that can be used in a cron and called manually at the same time. If there is a problem with the transfer, you even get an email.
