Proven method for server backups?

Does anyone have a proven good way too backup the rust server.

I have linux game manager. There seems to be backups generating but I don't think I set a cron for it.

More specifically my question should be:
What files are required to safely backup/restore a rust server.

I tried zipping the serverfiles folder but its too big. I dont need it all because I can reinstall.

So for the map, and plugin/user stats/saved info.

Also if anyone knows a bash script or something I can run via cron that I can run on another server to remotely back up the required server stuff, that would be awesome. I figured that part out individually, but maybe someone has some rust server specific stuff.

Any help is appreciated.

 

BackupExtended plugin, works a treat, basically gives you control over Rusts normal backup which I've found to be crap.

 

Checking it out now, thanks!
