There's been a few threads about this, but I haven't seen a definitive conclusion and I remember a conversation in Discord about it.

We're currently saving locally on the server and I would like to be able either schedule a save every x amount of hours, or better yet if there could be an option to run a local save whenever the last person leaves the server that would be awesome.

Very much like we can set up so when the last person leaves the modules shut down/pause, an option to do a server save at the same time could be very useful.
