Hey if Bukkit has an auto save feature, then why would I use the plugin AutoSaveWorld. My co-owner had added it to our plugins and I thought that that was the only way of saving your world up until now,
AutoSaveWorld is a multi-functional plugin that can save, backup, purge, restart the Minecraft server, reload plugins and much more. Some people just like this plugin.
I use world save plugins for one giant reason slot of times my staff dose stupid things by accident that my crash the server and any of my world will be save if that happens
